Slippin' into Darkness: Part 2

Chapter 4

The two mothers changed and then did their morning exercises in Susan's nearly professional-quality basement workout room. Suzanne joked around and acted gaily to put Susan back in a decent mood. They were nearly done with their sweaty workout when Suzanne decided to bring up the topic of Ron again.

As Suzanne pedaled on an expensive exercise machine, she said, "Susan, I'm very proud of your decision with Alan. It looks like your new attitude has prevented things from getting out of hand."

"Thanks. I think it's all for the best, too," Susan said happily. "I know you keep saying what I did with him wasn't wrong, but it FELT wrong to me. And regardless of what Ron may or may not have done to me, I had no right helping Tiger out that way without Ron knowing. And there's no way I could bring it up with him - no way. So the only solution is to leave the medical treatment situation in your capable hands."

Suzanne furrowed her brow, dismayed at Susan's conclusions. She thought, I haven't been hyping Sweetie up ever since Ron called to say he was coming back home. I need her to resume obsessing about his cock. She's gone cold. It's gonna take a while to get her back into a sexual heat.

Suzanne pretended to agree. "That's very wise. I'm glad it all worked out." But then she lowered the boom. "Just one problem though. Have you seen Sweetie lately? How he's been behaving?"

"I think I'm aware of my son," Susan said defensively. But then doubt crept in, and she asked, "What do you mean exactly?"

"Have you seen how much he's suffering? I imagine you haven't, 'cos he's been trying to hide it from you, brave soul that he is. It tears me up badly to see him suffer silently like he does."

"Suzanne, what on Earth are you talking about? He seems perfectly fine to me."

"Yes, he can be a good actor, can't he? He looks fine on the outside, but inside he's dying."

"Dying?!"

Suzanne explained as she pedaled, "I've had my suspicions, but he confided in me and now I know how he really feels. Since you changed the atmosphere around here, I'm afraid you may have gone too far. You killed the spirit of sexiness, so now he's demoralized, just like when he tried and failed to go out with Christine. You remember how he gave up trying to do his thing for days. But unlike then, he's still trying to do his thing six times a day. What a brave trooper."

Susan was extremely dismayed. "Haven't you been helping him? Wait! I don't want to know ... No, I'd better know - it's my responsibility as his mother. Oh God, tell me, but please don't tell me the details!"

"Have you seen his chart lately?" Suzanne asked, referring to the chart on his door marking the number of times he climaxed in a day.

"No," Susan admitted. "To be honest, I've been keeping out of his room altogether just to avoid having to look at that chart. I want to put all reminders of ... what happened ... out of my life."

Suzanne could tell when Susan was lying or not, because she was a lousy liar. She knew that Susan was telling the truth about not seeing the chart lately, which gave her the freedom to exaggerate about the results. "It's terrible, Susan, just terrible. He barely manages. It's been plummeting down on a six, five, four, three, two, one, zero trajectory."

Susan asked with great alarm, "Haven't you been helping? Everyone calls you the real-life Jessica Rabbit. Certainly you can stop that slide, can't you?"

Suzanne sighed as if the weight of the world was on her. "I've tried, I really have. But to be honest, I haven't been able to help that much. How can I, between Ron being here, and not wanting to offend you, and not wanting to violate the new restrictions you've created?"

That was mostly true, but now she lied blatantly, "It's growing tougher and tougher each day. It takes him forever to get hard, and longer still to ejaculate. He's in his room an hour or more sometimes, just trying to get erect. He tells me the porno videos and magazines you bought have done little for his inspiration, since he feels like he's failed in the real world, first with Christine and then by upsetting you. I stroke and stroke and stroke, but sometimes I can barely keep him stiff."

Susan clutched at her chest for some reason. "Don't you ... don't you, use your mouth?"

"Of course! I suck and slurp and lick like his erection is the tastiest ice cream cone in the world. And in a way it is. I engulf his great fat cockhead and bob over his sweet spot so much that my jaw simply can't take it anymore. And naturally I never stop stroking the rest of his shaft at the same time, unless it's to fondle his balls. Remember how I taught you to do that, and the way he really likes it?"

"Um, I do, but I..." Susan was so frazzled by the suddenly highly arousing turn of the conversation that she was having trouble remembering her resolve to put that kind of help behind her.

Suzanne sighed again, perhaps a bit too theatrically. "I bob up and down on his fat, long slab of hot and tasty meat like some kind of horny woodpecker. And you know I have a pretty unique tongue?"

"Yes?"

"I use that in every way I know how, licking from tip to base and back again, over and over, slathering his balls with my love, and just generally acting like some kind of wanton big-titted mommy slut! Of course, I kneel naked before him, letting him know that he has all the power, and I'm helpless but to serve him. But it's no use!"

Susan asked, "Do you wear high heels?"

Suzanne responded indignantly, "I'd be naked without them!" But then she chuckled, and added, "Of course, around Sweetie, I'm usually naked with them."

Susan couldn't help but giggle at that, despite her grave concern.

Suzanne concluded, "Sometimes even I can't get him hard at all, no matter what I try."

"Oh my! I had no idea!" said Susan, who suddenly felt both very horny and very worried. She thought back to her run-in with Alan the night before. She admitted, "But, um, last night, I was in the bathroom just across the way from his room, and I heard him, and even, uh, saw him. And he had no trouble ejaculating, I can tell you that!" She blushed as she recalled his cum squirting all over her body.

"How could you have seen him from inside the bathroom?" Suzanne pried.

Susan blushed a deeper red. "Um, I was, uh, I heard him cry out, and I thought he was in pain, so I rushed in, and, well, he was doing his thing."

"You mean he was jacking off?"

Susan nodded slightly.

"All by himself? That's extraordinary! I can't tell you how difficult it's been for me to arouse him at all lately. He must have been thinking about something incredibly stimulating. What did he yell out exactly?" Suzanne was hyping up her comment because she had a sneaking suspicion that he'd been thinking about Susan, and Susan knew it.

Susan turned away and replied so quietly that it couldn't even be called a whisper.

"What was that?" Suzanne asked.

Susan answered a tiny bit louder. "Something about me."

Suzanne was only able to catch that from watching Susan's lips. "Did you say, 'Something about me'?"

Susan dropped her head in shame and nodded almost imperceptibly.

Bingo! Suzanne thought. I love it! But she maintained a serious face. "Ah. You see? If there's one thing that gets him aroused no matter what, it's thinking about you. That's not terribly surprising. Everyone knows that it's normal for boys to fantasize about their mothers. But when a boy has a mother built like a brick shit house-"

"What does that mean, exactly? I don't understand that expression. Why compare a woman to a, er, commode?"

"It just means a woman who's fit and shapely, like a building put together as solid as a brick wall, and it usually implies having a great rack. But my point is, with you acting sexy and providing visual stimulation, he can easily get in a sexy mood, and I can help him or he can help himself without much problem. But when you act like you have been lately, almost nothing can inspire him. Of course Ron being here just makes it twice as bad. Frankly, we may have to give up on his treatment altogether."

"Oh no!"

"I'm afraid so. Maybe no man is meant to climax six times a day. Certainly that would be an impressive achievement for a married man or someone with a serious girlfriend, but can you imagine how it must be for someone who still hasn't even kissed a girl? To do it every single day? We'll have to talk to Nurse Akami, but I don't know how much longer he'll be able to go on falling far below his daily target. Perhaps he'll have to stop the treatment and take the other option. You know, the pill treatment that will give him breasts like a woman, God forbid."

"Oh no! Anything but that!" Susan moaned in **** distress. Both of them had long stopped their pedaling, in response to the seriousness of the discussion, but they remained on their exercise machines. "What can we do? We can't very well have things like they were before. I was out of control, Suzanne. Honestly and completely out of control. If Ron knew what I did last Tuesday, I think I would just die! I mean, it went way beyond helping. I really loved it! I'd be lucky if he didn't divorce me. And I'd like to help with some visual stimulation if it's really that important to my cutie Tiger, but how can I? With Ron here, we can't make things even a little bit sexy. He'd find it really bizarre to see me dress up for no reason. I don't want him to start asking questions. I already feel like I've committed a crime and have to cover it up. How horrible!"

"I know, I know. It's bad," Suzanne commiserated. "But there's always a solution. The problem is with you and this house, right? What if I took care of him from time to time some place outside the house? One session where I get really sexy could keep him going for days."

"I don't know," Susan said more than a little bit doubtfully. "I appreciate the offer, I really do. But..." Susan began to fish for objections - "what we really need to do is find him a true girlfriend. You don't want him to think of you as his de facto girlfriend, do you? After all, you're a married woman too, and twice his age!"

"I know. Don't remind me of either of those facts - I don't know which one I dislike more. But Sweetie's on the edge of disaster. We need to get him to climax six or more times a day, and fast! Preferably more, to make up for his recent drought. There's no chance of him finding a girlfriend who can help with something like that in a matter of days. So what can we do?"

"I don't know," Susan replied, still beside herself with worry. "Let me think about it. I'll think about your offer, too. But I hope there's another solution."

"So do I," Suzanne lied. "It's not like I want to be catering to him hand and foot in this weird way. I mean, his great big erection is just so hard to conquer. I lick and suck and suck and lick, and stroke, stroke, stroke. If I'm lucky, I get rewarded by a hot, sticky bath of his creamy cum all over my face and chest. But even then, I feel like his cock has conquered me!"

Susan held her breath, overwhelmed by a surge of arousal.

Suzanne pretended not to notice. "In the meantime, if you could be more supportive, that would help."

Susan nodded gravely. "And bless his soul, he's been trying to hide his suffering from me. What a trooper he really is!"

Suzanne was a bit surprised that Susan didn't accept her suggestion to meet Alan outside the house.

The real reason Susan didn't like that idea was that she felt possessive. In her heart of hearts she still wanted to be the one to whom Alan would turn first for a cocksucking or handjob, and she didn't want him to develop a strong crush on Suzanne.

This clashed completely with her renewed morality, but she unconsciously felt that way just the same. And she had a concern that with Suzanne and Alan getting sexual outside the home and with no one to drop in on them, they'd be fucking before long.

That, in fact, was Suzanne's exact plan. But Susan was now so **** to find a way to help with Alan's "crisis" that she seriously considered letting Suzanne have her way with him.

Now that the topic had been broached again, Suzanne made it a point to resume mentioning Alan's penis at every possible opportunity. She was still talking about it in mostly non-sexual terms while discussing his "crisis," but at least it had Susan thinking frequently about it again.

Chapter 5

In class later that morning, Alan found to his surprise that he could temporarily put the recent crazy sexual incidents out of his mind and focus somewhat on his classes.

It helped that he had other things on his mind. For instance, he spent a considerable amount of time thinking about his date with Christine the previous Friday, even though it was supposedly just a meaningless practice date.

The fact that Christine was in some of his classes helped ensure that he couldn't forget about her. Since they both were in the "gifted" or advanced track, they were in most of the same classes. And since they were both "teacher's pet" types, they tended to sit in or near the front row. Due to Alan's long-standing crush on Christine, he'd managed to sit next to her in those classes that they shared.

Because they were friends and had similar schedules, they sometimes walked from class to class together. For instance, they had the same first and second-period classes, so on many days they would chat while they moved to their next classroom in the five minute gap between those classes. In fact, since Alan had almost never seen Christine socially outside of school, these times between classes, as well as sometimes eating together for lunch, were the basis for much of their friendship.

That day was no different, so when their first-period physics class ended, they naturally fell in together as they walked to their next class. But it was different in one important way, because they'd had their first practice date after their previous day together at school.

"Hey," Alan said, trying to sound casual.

"Hey," Christine replied.

"So ... what's up? Did you do anything fun Friday evening?"

She laughed, since she'd spent most of the evening with him. She joked back, "Eh. It was okay. You know, the same ol', same ol'."

He was hurt at first, until he realized she was just kidding him. He played along with that too, yawning ostentatiously. "Yep. Same ol', same ol'."

There was an awkward silence after that. Neither of them really wanted to talk about their date. Although Alan would have loved to date Christine, after her initial rejection they had agreed to be just friends. He was trying hard to roll with that and not think of her in too sexual or romantic a way.

Christine, by contrast, was discovering that her romantic feelings for Alan had been growing steadily ever since he'd asked her out and she'd turned him down. She'd always liked him a lot, and lately he'd developed a new confidence and even a sexual swagger that made him much more desirable as something more than just a friend. She was particularly impressed by his behavior on their practice date. The truth was, she couldn't have imagined a better real first date. But she was trying hard to still think of him as just a friend, so she was as determined as he was to make it seem like the practice date was no big deal.

As a result, she decided to change the topic, even though they had been referring to their practice date in only a very oblique manner. "So ... got a lot of homework?"

"Enh. Not so bad. I've got a big test coming up in my history class, but that's about it."

"Oh, yeah. Ms. Rhymer's World History class. How's that coming along? We blondes are curious how the common folk live."

Alan grinned, but he also shook his head. Christine was so smart that she'd even managed to skip ahead of him in some subjects, in order to get college credits while still in high school. That was why their class schedules weren't even more similar. She'd had Ms. Rhymer's class the previous year and was taking an Advanced Placement history class this year. It just so happened that there was a greater percentage of blondes than usual in that class, and she never let Alan forget it. Since he liked to tease her with "dumb blonde" jokes, one way she joked back was to claim he was taking the "remedial" history class for "brunettes."

Knowing all that, he playfully teased, "Yeah, well, it's fascinating. We've been learning that it turns out history is made almost entirely by brown- or black-haired people, and even a few redheads. Pretty much everyone but blondes. Think about how many U.S. presidents were blonde, for instance. There's James Garfield, and ... and ... oh yeah. That's about it!"

She was all grins, because she loved this kind of bantering with him. "I'll have you know that U.S. presidents are just puppets. The REAL power lies with secret societies. All-BLONDE secret societies!"

"Yeah, right. Then how do you explain that Ms. Rhymer herself is blonde, and she's the one teaching us about all the famous non-blondes?"

Christine shook her head dismissively. "How naïve you are. Of course we blondes have to keep the dark-haired masses from the truth, so naturally Ms. Rhymer plays a role in that part of the plot. This whole 'dumb-blonde joke' thing you love is just another part of the smokescreen, and you're unwittingly helping us by spreading those jokes."

"Oh yeah? If that's true, then why are you telling me all this?"

She was just making up stuff as she went along, and that stumped her. But after only a brief moment she came up with an answer. "The truth is, blonde power is growing, Our fearless leader, Reese Witherspoon, thinks it's time we start to step out of the shadows and reveal our real role to the teeming masses."

He laughed. "Reese Witherspoon? Is she the supreme leader of the planet or something? And I suppose her role in last year's movie 'Legally Blonde' is somehow tied up in this grand unveiling?"

"Hey, pretty smart guesswork, for a brunette."

They continued to joke around like this until they were seated in their second-period English class and the bell rang.

When the teacher, Mr. Randall, started lecturing, Alan thought, Dang. She got me good this time around. But I'll get her next time. The interesting thing is how she deflected the conversation from our practice date, talking about all this hair color silliness until class started. She obviously wants to make it clear that that was no big deal. I was kind of getting my hopes up that she'd reconsider things, but I guess not. She probably doesn't even want to go on a second date. Damn!

Besides, how could we even get romantic now, what with all my sexual stuff going on lately with Mom and Sis and Aunt Suzy and whatnot? It's better just to play it cool with her.

At the same time, Christine thought, Talking to Alan is such fun! We have such a good rapport. I couldn't joke around like that with anyone else. Everyone else is intimidated by me; with him we're just pals on an equal footing. And Friday night was even more fun! If I wanted a real boyfriend, it would definitely be him. But, sadly, that boat has sailed already and I missed my chance. It's best to treat our date like the non-event it was supposed to be. Besides, I wouldn't even know what to say to him about it. "Hey Alan, I had a lovely time Friday evening"? No, that's too cheesy! And he might get the wrong idea. Even though maybe that wouldn't be such a bad thing...

No. What am I thinking? Gaawwwd, I'm terrible at this kind of thing! It's best to stay friends in any case, because otherwise I'd probably just screw it all up. Things would get weird and awkward and we'd lose this special rapport we share.

Chapter 6

Alan managed to keep his mind off his planned sexual hijinks during the second and third periods. But by the time of his fourth-period class with Ms. Rhymer, his plan to meet with his sister in the supply room just after class ended was getting harder and harder to ignore. The closer it came to the end of class, the harder it was for him to think about anything else. By the time class ended, he was acting like a total space case.

Glory couldn't help but notice how he wasn't paying any attention. It bothered her that this seemed to be becoming a pattern with him, despite his recent promise to be better. When the bell rang, she indicated that she wanted to speak to him after class.

But this time he just said, "Can't today! Gotta run," and hurried to the door.

However, before he could leave the classroom, Glory barked, "Now, hold your horses, young man!" She waited until he paused at the door, then she said, "We have things to talk about! Apparently you're in some big rush right now, so I expect you to see me here when the school day is over. Understood?"

He sighed like a typically oppressed teenager, but then nodded. Then he immediately raced out of her room and down the hall.

He had all the painting supplies he needed already prepared. This time he used his own illicit copy of the key to unlock the door to the supply room.

Katherine and Kim both eyed him from a distance as he entered the room. One at a time, they made their way inside shortly thereafter.

Kim was the last to enter the inner closet within the supply room.

While they were getting settled, Alan couldn't help but notice that they were both wearing their cheerleader outfits. This was unusual, since all cheerleaders only wore their outfits on Friday game days. To wear them on any other day might raise eyebrows, especially by the other cheerleaders, so they'd both put their outfits on just a minute or two earlier, thinking that he would find that look extra sexy.

They were right. There was something about those red outfits that got him very horny. Seeing other cheerleader outfits from other squads didn't do much for him, but those colors had special meaning for him since both Katherine and Amy were on the squad.

As soon as Kim entered the inner closet, Alan said with a big smile, "Hi, Kim. My name is Alan. Now get naked." Of course he didn't have to put it that way, but he was in a good mood. He felt confident, so he decided to let it all hang out, both literally and figuratively.

Katherine had the same attitude. She cuddled up next to him and said, "What about me, Big Brother? Don't you want your sister to get all naked too?"

"It's not necessary yet."

She pouted exaggeratedly, "But would you mind? Wearing all this clothing is chafing my skin! It could cause permanent damage!"

"I think permanent brain damage is more like it." But seeing that she didn't like his joke, he said, "Oh, all right." It occurred to him that Suzanne had delighted in complaining about "chafing" too, which he found arousing and amusing.

He considered their situation and added, "But remember, we have to act quickly, especially since there are two of you to paint. Oh, and Sis, last time we were silly trying to keep the skirt up all the time. It's easier if you both just take the skirts off."

Katherine took off her skirt, and Kim did too. They both had on their form-hugging cheerleader tops, to simultaneously tempt him and remind him that they were cheerleaders.

Kim said, "I just have to say I think this whole thing is really sexy."

Alan nodded. He looked over and was surprised to see that Kim had pulled her top up over her boobs, as well as dropping her skirt, perhaps to ensure he didn't get any paint on her top. Whatever the reason, it turned up the sexual heat in the room.

He noted that she seemed a bit nervous, despite her willingness to bare her body. He saw that she had shaved her pussy. That, plus her slight hips and smallish boobs (by his standards, at least), made her look even younger than she was. He thought, Damn. Talk about robbing the cradle. I must be committing some crime here, for sure.

He looked at his sister and added to himself, Several crimes at once, probably. But he was resolved to do the pussy painting anyway.

Katherine noticed him staring at Kim's crotch and said, "She's already shaved for the paint job. Don't worry. We met before school today and had a nice, long talk. We decided it would be more fun if we both went without underwear for the whole day, in case you're wondering why we didn't need to take them off. I told her all about my unnatural lust for my big brother, and she's perfectly fine with it."

Alan was horrified. "What? You told her that? Kim, it's not true. In fact-"

"Chill out," Katherine interrupted. "I only told her the details 'cos she'd already guessed the rest on Friday. Mostly because she noticed you checking out my pussy with your binoculars."

"Oh ... Oops," he said, nearly speechless. His dick went flaccid in a matter of seconds. Fuck, fuck, fuck! We're fucked!

Katherine continued, "But don't worry. She's the only one with a clue about this, 'cos I told her you were the painter. Anyway, judging from just how much her cunt was dripping in the girl's bathroom this morning, I think it's safe to say that the idea of you and me together gets her quite hot. Wouldn't you agree, Kim?"

"Definitely! Go for it, you two," Kim replied enthusiastically.

"What, you mean like this?" Katherine leaned in and kissed Alan right on the mouth.

He found himself thinking, So maybe Kim is cool with ****, but can she be trusted? That's the big question! But he found himself highly distracted. Soon their tongues were enmeshed, and their hands ran all over each other. Before long, he forgot all about his worries.

Alan's hands quickly found his sister's naked ass. It occurred to him as he kissed and fondled her that, despite all the sexual fun he'd been enjoying lately, he hadn't been able to French kiss much - the only time he'd been able to do it was recently with Katherine. He could understand Susan wanting to stick to her rules limiting intimate contact, but he didn't understand why Suzanne was also **** to kiss him.

Thinking about boundaries and rules renewed his worries about the wisdom of kissing like this in front of Kim. "Katherine!" he chided as he gasped for air. "What about boundaries? Don't you remember the boundaries?" By "boundaries," what he meant was that it wasn't prudent to do anything overtly incestuous in front of Kim. It was one thing that Kim had approved in theory, but how would she react if she had direct visual evidence? But he was trying to say that in an oblique way since Kim was right there listening.

"What do you think about boundaries, Kim?" Katherine asked, since Kim was standing there nearly naked.

"I say: 'Fuck the boundaries!'" she replied.

"You hear that, Bro?" Katherine still held him tightly. "I think we have to take her advice very seriously. Especially the suggestion to fuck." She giggled.

"Let's talk about this later," he replied nervously as he pulled away from the hug. He glanced at Kim, which only heightened his worry about her knowing about the ****. He really wished his sister hadn't made things worse by mentioning fucking. Plus, he was well aware that their available time was passing quickly. "We've got less than forty minutes to paint both of you. Let me start with Kim since I think I can do Katherine pretty quickly."

"I hope that when you 'do me, ' you'll take your time," Katherine shot back, and then giggled some more.

Facing Kim's butt, Alan began painting. At the same time he asked his sister, "By the way, Sis, speaking of painting, did you paint that top on? Your nipples are soooo noticeable."

"You noticed!" she said, delighted. "Actually, it just looks painted on, 'cause it's so tight. When I see you my nipples always turn into hard little erasers. But I've also been pulling my tops tight in front to stretch the fabric and get you even hornier."

Kim said in response to this, "You two really need to get a room, seriously. Both of you are like dogs in heat. You're so ready to go. Basically, I'm a lesbian, but just thinking about you two is so damn nasty that it gets me all worked up. I've read about ****, but I never thought I'd see it up close like this."

"It's not ****; she's helping me out with a real medical problem," said Alan in a hurt voice.

Kim guffawed out loud. "Medical problem? That's a good one! I have a boner and have to stick it in my sister for relief! That's hilarious. You're not serious, are you?"

Alan wanted to tell her about his medical diagnosis, but remembered that he shouldn't tell anyone else about it. It appeared that his sister had kept his secret; he needed to also. He further realized just how silly it would sound if he did give his medical story. Now that I think about it, the whole thing does sound completely absurd. Was that really my diagnosis, or was it some kind of weird scam?! For what purpose would the doctor lie? How would he gain from it, except for a few more appointments? Or did we take a valid medical thing and turn it into something twisted and sexual? What would Dr. Fredrickson think if he could see me now?

But he was distracted from further thoughts because Kim added, "You know, I'm getting so horny watching you two that I want to pleasure myself. Would that interfere with your painting?"

Alan worked on the top of Kim's butt. "Not at the moment, but it will later."

"Okay, fine, tell me when I have to stop." She began to slip her fingers in and out of her slit with one hand while rubbing her clit with the other.

Behind him, he heard his sister say, "Big Brother, could you stand up for a second?" She'd always called him "Big Brother," but lately she did it much more than before and usually emphasized the word "big."

He reflexively stood up before thinking to ask why she wanted him to.

Katherine immediately pulled his shorts and underwear down to his knees. "That's better. You can kneel back down now," she said.

He did.

"I think we already need to reward Alan for his work," Katherine said, as she reached around his waist and began to jack him off.

Kim enthused, "You two are so hot!"

He asked her incredulously, "Are you really okay with this?"

"I am!"

Katherine added, "She is. Besides, I know what you're thinking: can she be trusted? She can! It's a long story, but she's already passed that test. If she hadn't I wouldn't be so open in front of her. I may be crazy for you, Bro, but I'm not THAT crazy! Basically, she totally had me over a barrel and could have made me her sex **** or worse, but she didn't. She's cool, and a good friend."

Katherine and Kim shared a smile.

Alan felt a lot better hearing that, even though it didn't completely dispel his worries.

Katherine joked as she stroked, "Besides, if I'm gonna be anyone's sex ****, I wanna be yours, Brother!"

He pretended not to hear that, because he found it far too arousing and didn't know how to respond.

Kim saw the look of concern still in his eyes, so she said, "Look, if you could have some kind of out of body experience, you'd be able to see you and your sister like I do and realize that seeing her stroke you like that is the hottest, sexiest thing in the history of the world! Just looking at you doing that almost makes me want to give a dick a try."

"It's never too late to start," encouraged Katherine as her fingers pumped. "I'm not too picky about sharing his marvelous cock, as long as he knows where to stick it when he gets back home at night."

"Hey, I don't stick it anywhere when I get back home at night!"

"That's your problem, Bro. Are you beginning to get the subtle hint that I wouldn't exactly mind?" She looked at Kim and rolled her eyes. "Alan has certain boundaries he says we shouldn't cross."

Then she looked back at her brother with fierce determination. "Fuck the boundaries already! Don't you know I wouldn't mind if you pushed your meaty schlong up really deep into the very center of my body and pounded me over and over again, every night and every day? Not only that, but you said yesterday that you owe me a big one, that you'd do any favor for me. The big one you owe me is in your pants, very BIG Brother, and I command you to fuck me with it as my favor."

Her hands flew fast over his erection now, and she leaned forward in the very tiny room and rubbed her boobs against his back. When she stopped talking she began to nibble on his ears, only because she couldn't kiss him on the mouth from her position.

He stopped painting (not that he'd gotten a lot accomplished so far), stood up, turned around, and held Katherine's shoulders. "You're making me so horny, I can't stand it anymore." He glanced at Kim, and saw a genuinely sex-crazed look on her face. He thought, Fuck it! She knows this much already; how much worse could it get if she knows a little more?

Then he turned back to Katherine. "Okay, I admit it: I wouldn't exactly mind, either. Fucking, I mean. And you do have me over a barrel on owing you one, dammit. But just 'cos we might want to do it doesn't mean we SHOULD do it. For one thing, we'll get caught. Can't we at least wait until our father goes overseas again before we talk about this?"

Katherine just wanted to fuck, not talk. With a pout, she simply answered, "No." Then she kissed him passionately on the mouth.

He enjoyed the kiss for a while, but eventually he pulled away again. "How can I finish this painting? Cool it down, okay? People might hear. Someone might walk into this room at this very moment! Remember, we're doing this in the middle of the school!"

That thought drastically cooled his passion. He turned around and began painting again. "Sorry Kim," he said, "but my sister is so horny that I think the only solution is to lock her up."

"Given that she's now my sex ****, that can be arranged," Kim responded wryly.

"Oh no, not you too. Don't encourage her!" said Alan.

They all laughed.

Katherine again reached around Alan from behind to fondle his prick some more. "I'm sorry, but I'm just so excited. Big Bro, do you realize what you just said? You admitted that you want to do it. Do the nasty! How sweet!" Her hands slid up and down, sped along by his pre-cum. "You want to drill this big, fat thing deep inside me and pump me full of your baby makers! How can you expect me not to cream all over when you say that? Now we don't have to play games anymore. You're going to deflower me! It's only a matter of finding the right place and not getting caught."

"There's no way," said Alan, still worried, although also extremely aroused, thanks to her words and her busy fingers. "It's too risky. I'm only agreeing 'cos I'm temporarily insane from what you're doing to my prick."

He began to focus more on painting. It wasn't easy, with his sister's hands on his stiff rod and Kim frigging herself mere inches from his face.

"Oh, Alan! Brother!" Katherine said swooningly. "We're going to do it! We're gonna fuck! I can't wait!"

He protested, "Shhhh! Don't call me that in a sexual context at school! What if someone's listening right now? This is total insanity! Please don't say another word, I beg of you!"

She took her hands off his tool momentarily, took her top off, and then took off his T-shirt. Then she leaned into him and rubbed her naked boobs up and down the skin of his back. It was the best she could do from her awkward position behind him, but it still made him feel great, especially as she soon had her hand back stroking his erection.

Alan put the brush down. He whispered, "Kim, I'm done with the butt. Don't ask me how, because certain naughty sisters are being more than a little distracting." He realized he was in danger of shooting his jism all over Kim, but kept trying to focus on the paint job. He was hasty, because it was a race to finish before he came all over a virtual stranger.

Finally, he said to Kim, "You can turn around."

Kim turned.

"Katherine, you have to stop that, or I'm going to ... going to ... Oh shit! I'm losing it! Let go!"

Alan had to cum, but there was no safe place to dump his load, with Katherine behind him and school supplies from wall to wall. Still worried about what Kim would think, he began to squirt into his hands. He tried his best, but what missed his hands splattered onto one of Kim's legs.

When Katherine realized his cock had started to spurt, she increased the speed of her stroking and gripped his rod even tighter.

"Sorry!" he said to Kim as it all came out. His feelings were so intense that he had little control over where he was shooting and just hoped not to make too big a mess.

Kim had never actually seen a penis cum before, so the sight of Alan's big shaft spurting stream after stream of cum was thrilling for her. As his hot cum splattered onto her leg a tingle of excitement shot through her whole body.
