Relief with Mom and Airi

I was laying out on the couch in the living room, just relaxing and enjoying fun thoughts of just how awesome my life now was. Also I had my cute sister lying against me as she watched the television, wearing shorts and a loose t-shirt and nothing else. I knew this because my hand was free to wander underneath her clothes and there was no bra on her soft globes nor panties over her increasingly sticky slit.

Currently, I was absently teasing Airi's folds and enjoying the way she squirmed and sighed, tweaking her quite hard nipple with a couple fingers while the others stroked the rest of her breast flesh. I was extremely aroused, the heavy length of my erection pressing hard against Airi's lovely little behind. She didn't mind, of course, thanks to that normality. In fact, her hips kept slowly squirming, rubbing the cleft of her ass around it quite pleasurably. I had basically been a saint in terms of not going crazy with Kotori, Umi, and Honoka today. Even so, the ghostly sensation of Honoka's soft lips was still tingling upon mine and I reveled in the fact that I'd been able to kiss her like that. Earrings-based confidence but it still counted.

Ahh....

Kotori. Umi. Honoka.

Honoka...

My perverted imagination kept coming up with all sorts of sexy scenarios and I found it difficult to resist doing them because of how easy it would be. It continued to blow my mind that I could have just taken my dick out during our pleasant conversation today and stick it in their pretty mouths. I thought about Sumire, the girl I'd lost my virginity with on a whim, and the desire to take each of my new friends' cherries was hard to deny.

“Hey. How was Science Club?” I asked, retrieving my hand from Airi's shorts and gently slapping her butt.

“Just fine! Nothing exciting to report!" chirped Airi, wiggling a bit. "How was your day?" she asked, "Were those girls all over you?"

I laughed, "It was great! Why do you say that?"

Airi giggled, "Come on! My super-cute oni-chann in an all-girls school! Of course, they are going to be after you! Did you make any friends?"

"Oh definitely." I replied as I tweaked her nipple.

She gasped a bit, one of her hands cupping my hand through her shirt. "Ah-ah W-well, tell me a-ah - about them!"

I told her about my new friends, gently rubbing along her navel with one finger. She asked questions often and somehow zeroed in on Honoka as my crush, teasing me gently about it. I easily parried by inserting a finger fully inside of her hot and wet vagina.

Airi shuddered and a small gasp followed by a light little mewl escaped her lips in response.

My phone buzzed, indicating a message. I wasn't going to bother with it but Airi spoke up.

“Are you going to check that?”

“Nah... I'll look at it later.” Seriously, my sister's wet little pussy was far more interesting right now.

“But what if it is someone sending you a picture?”

“So...?”

She pushed up off the couch and twisted around to me, “Oni-chan! That would be so rude. What if they put a lot of effort into looking nice and making the shot look good?

I stared at her as I realized she knew about girls in my contact list sending me pictures and I wondered why. Does everyone instinctively know this stuff? Does some random guy in South America inexplicably know what is normal about me? How does that work? “Um... how do you even know that girls send me sexy pics of themselves?”

Airi looked confused, “Why wouldn't they? Mom and I do.”

“Yea, but why?”

She drew her answer out, eyebrows drawing together, “Becaaause it's the normal expected thing you do. What, you don't like it? You know, you never did send me a response about the shots I sent you! Wait. Are you not replying to anyone's pics?!” She smacked my chest at my expression, “Oni-chan! How could you!?”

She then snatched my phone up and flicked the photo on. Her eyes went wide, “Oh wow! This one is amazing! Look at it!”

I soon had my lovely teacher before my eyes as she sat on the side of a bath tub, thick soapy suds obscuring her loins and her breasts, but leaving acres of smooth wet flesh exposed to my feasting eyes.

“Isn't that really sexy?” prodded my sister, “Now think about all the effort she put into to that and how it feels getting nothing back?”

“Um...” I started, feeling a little bad, “I'm not sure if Miyami-sensei would appreciate lewd comments from her student saved on her cell for later prosecution.”

“What? What are you even talking about? No one is going to get mad about you sending perverted messages to your teacher! And it doesn't even have to be lewd. You could just say: Wow! And Thanks! That's it. How hard is that?”

“Um.... not hard.” I answered dumbly.

Airi smirked and rocked her pelvis against my crotch, giggling, “Something else is though!” She then thrust my phone into my hand and ordered me to respond to Miyami-sensei. I did so with an unoriginal 'Wow! Thanks!”. My sister snatched the phone back when I was done, snorting and shaking her head at what I'd sent.

Then she proceded to go through the rest of the pictures I'd been sent. She made soft sounds of approval as she went through them. I noticed her hips wiggling slightly against my hard-on as she did so.

“Who's this?” she asked as she showed me Sumire-chan's photo, “Your girlfrieeend?”

I took a moment to appreciate how exciting I found this situation, my sister going through all these sexy photos and finding them perfectly acceptable. I took great pleasure in telling her, “No. That is Hirano Sumire, president of the Swim Club. We fucked in the shower after their practice.”

Airi's response was awesome. “Ooooh!” she cooed excitedly, “Will you tell me all about it?”

I told her about it.

By the end of my story, the level of my arousal had hit a new high. My sister listening with rapt attention and asking all sorts of questions about how it had felt to have sex, was more than enough to have my member throbbing and almost twitching between my legs. My fondling of her body increased to the point where I was driving a finger in and out of her wet slit at a rapid pace.

“Unghh...ahh! Your fingers feel good, oni-chan!” Airi mewled and gasped.

It should be no surprise to anyone that a couple minute later, I had divested my sister of her shorts to very little protest from her. So now she was on all fours upon the couch wearing just her shirt, with her delectable ass with the sweet folds of her pussy peeking out between her thin thighs and the tight pucker of her asshole exposed to my eager gaze as I sat beside her, my hands all over her.

I slapped and squeezed one ass cheek even as I used two fingers from my other hand to spread open her pussy lips, staring at her glistening wet pink insides. My erection throbbed heavily in my pants, the thick weight of it pressing uncomfortably against the seam, and the desire to take it out and stick it right in this tight little hole was incredibly strong.

It was at that point that mom came home, the front door shutting behind her. Feeling like a fox in the hen-house, my hands jerked back away from Airi's butt. However, as my mom came into the room, unbuttoning the top four buttons of her blouse, she wasn't too concerned.

"Aye look at you two. Being awfully naughty, huh?"

Airi ducked her face in her arm and there was a sense of frustration in her body language somehow. She raised her head, "Moo-oom!" She complained before continuing, "I'm not doing anything naughty. He was the one taking off my shorts and playing with my butt!"

Mom quirked an eye, asking dryly, "Did he take your bra and panties off too? I don't see them anywhere." Yes, I had nothing to do with that one. Airi hadn't had them on when she joined me for tv watching couch snuggles.

"Um..."

"That's what I thought." she remarked dryly before leaving the room, heading upstairs to get changed.

Airi sat up, pulling her delectable private parts away from me.

"What was that about?" I asked her, still pretty amazed by my mother's total nonchalance about the fact that I'd been playing with my sister's half-naked body right in front of her even after all this time of it sinking in.

Airi's face was as red as a tomato but she just shook her head, "It's nothing." I got the impression that my mom and sister had recently had a discussion about me and I wondered about the contents given all of my recent changes to normality.

The mystery of it did not distract me for long because my undeniably sexy sister was still wearing only a shirt and my boner had not relented in the slightest. I thought about all those tissues I'd made use of last night and my now strong desire to not resort to that method of relief. I didn't know if I was ready but I knew this path was sort of inevitable given my personality and powers. My erection was throbbing in my pants and I knew what I wanted to do.

Though I knew Airi wouldn't find it odd, I went ahead and covered my mouth and leaned away a bit as I quietly said, "It is normal for my mom to take this opportunity to teach Airi how to give a blowjob using me." I totally could have made a change that had both of them acting like my enthusiastic sex partners instantly, but taking it step by step seemed more fun. Besides maybe just a little sucking would sate my urges for now and my conscience could live to battle on another day?

In any event, I was still plenty horny so I sidled up next to Airi, slipping a hand down to press apart her thighs while the other snuck around her back to cup her boob, palpitating it gently. The tension seemed to then just drain right out of her and she leaned into me sighing. "You like that?" I softly asked, my lips at her ear.

"Y-yes...." she breathed, her hips squirming a bit upon the couch.

I fondled her like that for several minutes and for some reason Honoka drifted into my brain as I wondered what it would be like to hold and play with her body just like this. It wasn't exactly fair to Airi but given that at least half her attention was still on the television, I supposed I shouldn't feel too bad. I kept remembering what I'd said to Honoka and feeling embarrassed. My little speech had been so corny. I was actually blushing about that while I teased my index finger around the little hood atop Airi's slit (which seemed to be awfully sensitive, the way she kept squirming and hitching her breath). Still, even though I felt kind of stupid about it, it was also a pretty cool moment I had to admit.

It wasn't long before Mom came back down in some casual clothes, a loose white shirt that nonetheless did nothing to hide the great swell of her chest and a long pleated skirt. With a meaningful look at the thick bar of my erection, she told us, "Before things here progress, I think we should have a little lesson." She knelt before me, placing her hands lightly upon my knees, "Come join me, Airi."

My sister had an impish grin on her face as she slipped down to squat beside Mom, her unrestrained boobs jiggling energetically underneath her t-shirt, "Finally!" she breathed.

I feigned ignorance, "Uh...what's going on, you guys?" I couldn't resist reaching out with both hands and grasping their chests, rubbing my thumb gently up and down. Mom's breasts were so big and soft. Airi's weren't small by any means but they were dwarfed by Mom's. My thumb easily finding my sister's hard nipple with a back and forth swipe while I'd have to go exploring down Mom's grand slopes and into her seemingly vast bra-cup to find hers.

Mom reached for the waistband of my pants casually as she spoke to me, "I'm going to teach Airi how to orally pleasure you. Now I know that you can have any type of sex you want with her, but my preference would be for you two to just stick with blowjobs for now."

I blinked as my pants were undone by her deft fingers. I was struck with surprise by my Mom's casual assertion that I could fuck Airi if I wanted but then I remembered my change to normality involving everyone not minding if I did sexual things with anyone I chose. Huh. It was interesting to see Mom exerting what parental authority she had while working within those extremely liberal limits. She couldn't forbid actual vaginal sex but hoped to influence my decisions anyway, perhaps by ensuring Airi was so skilled at blowing me that I'd remain satisfied with just that?

"Lift your butt, honey." she told me while reaching under me to grasp and pull down my pants and underwear as I obeyed her.

My exuberantly hard and exceedingly swollen member jumped out into the cool air to sway wildly before them. Mom helped me to pull my clothes down and off my legs fully and I spread my legs further for comfort and to accommodate the both of them. I felt incredibly exposed and self-conscious to be naked from the waist down but I suppose I now knew how Airi felt. My sister's eyes almost seemed to be bugging out of their sockets and I almost had to laugh at her expression with her jaw hanging open as she stared.

"It... it's so big." she sputtered and I loved it though how much experience Airi had to judge such things I didn't know.

But then Mom agreed with a calm, "Yes." as she took a hold of both my shaft and my testicles lightly, "My but you are definitely in need of some relief."

I didn't know what to say. I was too turned on to think and much too focused on watching and feeling my Mom's hands on my cock to care.

"Go on, Airi. You can touch it." she encouraged, "Have you touched one before?"

My sister's face was bright pink as she reached out, "No! I haven't even seen one in person before. Oh wow! It's soft and hard." I hissed lightly as she gripped my shaft even as Mom seemed to be gently rolling my balls in her hand below.

Oh god. This situation was so hot and I'd been on edge all night. I wasn't going to last long.

Mom frowned slightly as she observed Airi's technique, "I feel a bit silly. It was my idea to teach you now and I'm really no expert. Mmm. Perhaps you can watch and learn from what I do? Does that sound alright?"

I suddenly very badly wanted to feel Mom's beautiful lips around me and I eagerly nodded my head with a thumbs up, "That sounds great! Yea!"

Airi giggled, her eyes sparkling at me before she looked to Mom, "I think someone really wants his blowjob, huh?"

Mom's quirked her mouth at me, "Uh huh. Just remember to tell me when you're getting close so I can back off. Semen is really not a pleasant taste."

I watched my mom's soft lips descend as she tried to take my dick into her mouth. I felt her lips stretch incredibly taut around the thick head, her face writhing a bit as she hit an immediate wall of resistance. She suddenly retreated, looking surprised and slightly out of breath. My cock popped out of her mouth and her beautiful eyes met mine. I guess this took a lot of physical effort. Then her tongue slithered out to lap all around my glans and she made a humming sound of delight. Then her head plunged back down, taking what she could fit and sucking with renewed enthusiasm, going "mmmmmMMmmmm" repeatedly.

Okay, that was incredibly arousing. I had no doubt that my mom had just learned that she really liked the taste of my cock.

I groaned and squirmed slightly on the couch cushion, the sensations of my Mom's mouth were incredible. She licked me, not using her hands at all. Her head ducked down out of view and her tongue made brief bold swaths against my shaft, right above my sac. I marshaled my will, taking a deep breath as I battled the approaching orgasm. She licked me again, higher this time as Airi watched biting her lip. Mom's tongue danced playfully on the underside of my glans. She really seemed to emphasize the use of her tongue rather than taking me into her mouth more like my previous blowjobs. I wasn't sure if that was general preference or her just really enjoying the taste of my penis.

She stacked both of her hands firmly around the base of my cock, and with that support, she began to push and lap her tongue more forcibly against the vast amount of exposed skin, licking fervidly.

Mom seemed to catch herself, opening her closed eyes with her tongue still fully slathered against my cock-head. An embarrassed expression appeared and she sat back, closing her mouth. "Ah. I was a bit carried away I think."

I smiled and gave her a thankful look, "Well, I'm glad you stopped. I don't know how much longer I could hold out. Although actually I'm not that glad..." My cock twitched and strained, feeling massively full with blood and actually aching with need. I really wanted to cum!

"Oooh!" exclaimed Airi, pressing forward, "Is it my turn now?" Her nipples were like bullets against her t-shirt.

Mom stopped her with a hand, "Wait, Airi. Give your brother a chance to cool down, please. He's definitely right on the edge of ejaculation. Do you see how swollen he is? How dark his cock-head has become? You can also see the tension in his body, his face."

I was deeply self-conscious and embarrassed to be observed and studied this way, in this situation but also incredibly aroused and willing to act on impulse. So I had no problem asking Mom to take off her top so that I could see her breasts.

She agreed calmly and even had Airi strip off her shirt as well. I feasted my eyes on my sister's beautiful tear-drop shaped boobs but when the pale mountains stuffed tightly in Mom's large white bra-cups were revealed I was stricken. Even more so when she reached into one of those cups with one hand and pulled at one like it was a giant melon, it struggled to break free. It soon flopped out, the light pink aureola taking up a startling amount of breast space topped by a short rather thick looking nipple. Soon enough she extracted her other one and they sagged significantly lower on her chest yet still had plenty of shape, like Airi's but scaled up to a massive degree.

Mom squeezed them a bit with her hands and used her arms to press at them from the sides, doing delightful things to their jiggly mass. She was watching me as she did so and she had a small smile on her face and said knowingly, "Did that cool you off or just make it worse?"

I suddenly very badly wanted to feel my dick between those massive boobs but Airi and I had to bit my lip as my cock still throbbed. This was steadily becoming one of the hottest moments of my life and it was all I could do to restrain myself from really just going crazy.
          
I smirked back at her, “Worse. But I think I'm good for Airi to try.”

That was what she had been waiting for, because Airi dropped the hand that had been sneakily cupping and stroking the underside of one of her boobs to press forward quickly. She grabbed my dick a bit roughly even as she brought her face in close, immediately breathing in and saying, “Woah. You smell really nice down here. I did not expect that.”

Even as I appreciated the fruits of that normality (the thought girls would like the smell of my junk was endlessly amusing), Mom leaned forward a bit to sniff, eyebrows raising a bit as she too seemed to like the scent of my cock and balls. Apparently she had avoided breathing in through her nose earlier because she believed the opposite to be true... heh.

I gave Airi a sarcastic, “Thanks, sis.” and she rolled her eyes at me, “Uh-huh. You like it.”

She then grabbed my shaft right beneath the glans, looking to Mom, she asked, “Like this?” and she brought it towards her mouth.

Mom nodded, “Yes, go ahead. Just suck on the end for a bit.” She pressed close, brushing Air's hair back and out of the way, an intimate gesture that I found surprisingly arousing. The fact that my Mom's immense pendulous breasts pressed against Airi's nude side only made the effect stronger.

When Airi's lips stretched as wide as they physically could just to close around my cock head, I think I found the actual sight itself of my very own sister's pretty face struggling on my dick just as pleasurable, if not more so, as the tactile sensations of her wet warm orifice. She sucked me like that, bobbing her head repeatedly for several long moments before she took initiative and laid a trail of tender soft kisses down the underside- which felt amazing.

She came back up with long licks up the side of my shaft, eyes wide in a repeat of Mom's reaction, “Wow! I had no idea penises tasted like this!” She eyed me, “We should do this more often. Like everyday.” Then she went right back to licking towards the top as Mom shook her head with an amused expression at my exaggerated silly grin with two thumbs up at Airi's suggestion.

She kissed my tip and asked, “What else, Mom?”

Mom looked put on the spot again, brow furrowing slightly. I could tell that my Mom had never once put much thought into giving blow-job lessons despite my normality. It made me wonder what that seemingly oral expert, the director's lesson would be like for Kotori. I suddenly very much wanted to expand blowjob lessons as a normal practice for all Japanese mothers and daughters, but I resisted the urge and kept my promise to myself. Though I was definitely going to think hard on it later tonight. I really wanted to see Minami-sensei in action with Kotori or perhaps just asking my new friends about their special oral practice with their mothers would be fun.

Mom finally decided, “Try sucking on his testicles, honey.”

Airi nodded but she didn't simply jump down to them. She alternated between sweet kisses and long lewd licks down my member with pleasant sounds of almost culinary delight slipping from her mouth. Then I felt a kiss at the loose skin of my scrotum and then a tentative lick and she giggled, “Okay, this should be so gross but they smell and taste so good, ohmygod I just want to stuff them in my mouth!”

I rolled my eyes heavenward, thanking the spirits for these earrings.

Mom smirked slightly, shaking her head minutely, “Just try one for now. Gently mind you. They're fragile as I'm sure you know.”

I had to see this and I grabbed my length pulling it against my abdomen and out of the way.

When her lips spread around my left nut and I felt it introduced to the warm wet cove of her mouth with a slowly exploring tongue, I couldn't help but squirm and let out a small moan. An intoxicating tingle shot up my spine.

Mom smiled looking at me, "I think he likes that Airi. Just suck on it slowly."

She did so and I was in some kind of exquisite heaven. My beautiful younger sister had one of my balls in her mouth as my topless mother looked on with approval!

My other nut was feeling rather left out, "Uh...Mom... would you suck on them too?"

"Yes, I suppose I could show her how I do it though there isn't much to it really..."

Oh but there was!

Something about Mom's manner in contrast with Airi's enthusiastic bluntness made all the difference. It was slow and maybe she was just hesitant, but it felt incredibly sensual and erotic.

She dipped underneath me and lifted an open mouth to gently cradle the ball before suckling gently on it. She drew on it, pulling it ever so gently while her tongue caressed the portion in her mouth. The orb fell from her lips when they gradually began to purse. And then she moved to the next, repeating the entire, delicious process.

Seeing and feeling my Mom doting on my balls was incredible and my cock trembled and twitched in my hand. My scrotum left the her mouth. She spoke then, but only after giving a hot, smooth lick up through the middle of my balls. “Did that feel nice?” she asked, though clearly knowing the answer by the tiny quick of her lips.

I nodded tightly, motioning in an almost frantic begging way for her to continue and she did so without ever breaking eye contact, Mom leaned in and started giving the head of my cock little kisses with her soft lips, small licks, a light suck. With a small giggle, Airi went back to tasting my balls, similarly staring at me with big eyes past the base of my cock.

For some reason the unbidden the image of Honoka, Kotori, and Umi flashed into my head, Honoka's cute face blushing the way she'd had during my stupid (and awesome!) confession, only this time it was as she pursed her lips about my tip while Kotori and Umi slurped on my nuts below.

Suddenly, I could feel my orgasm lurching forward and Mom apparently had been watching closely because she pulled Airi back. I couldn't help but whine a bit and I felt the strong urge to grab my cock in hand and pump it to my no doubt volcanic conclusion. “Co-come on, Mom... I need to cum!”

Her perpetually calm expression slipped to one of open sympathy as she took in my urgent condition, “Ah. Okay. Here. Take off your shirt.”

I didn't know why she wanted me to do that but I wasn't arguing. I whipped it off with her help. She then grabbed my wildly swaying prick in both of her hands, telling Airi, “When they tell you that they are about to cum or when you can tell they are close. Stop sucking and use your hand. They might even prefer to do this themselves- your fath- eh-hem. Watch.”

I wanted very much to make my Mom take it in her mouth because I knew she would like it but I wanted her to come to that decision at least somewhat herself and anyway, all conscious thought evaporated when she started tugging on my cock really fast, she stood up on her knees, her huge jugs heaving and swinging wildly as she did so. I began to groan and writhe slightly as white spurts leapt from the head of my cock, firing straight up into the air as Mom directed. My own semen came back down to splatter across my chest and stomach as was clearly what she'd been aiming for, my final successive shots came with much less **** falling to liberally drizzle upon her now slowly pumping hands and my own member.

Mom laid my softening member down upon my messy abdomen before she got up, "One sec, honey. I'll get a towel." She left the room leaving me alone with Airi sitting on the floor draped against the inside of my leg.

She looked a bit dazed and flushed, one of her hands hovering between her legs. I was a bit uncomfortable that she'd seen me ejaculate and now covered in my own sperm. It didn't seem all that sexy but based on the way she looked at the moment, maybe I was wrong.

I scooped some of my semen, suppressing the urge to wrinkle my nose, and offered it to her on a finger, "You want to try some?"

Airi focused, a small grin appearing as she shot a glance towards the kitchen where Mom had gone. Then she suddenly glomped onto my finger, sucking lightly and I felt her tongue run across it.

Her smile grew big when her mouth popped off, "Mmmmm! That tastes so good! What was Mom talking about?! Now I know why girls like to give blowjobs! I knew why guys liked them...."

When Mom came back a few moments later, she stopped short in the doorway with a frown at what she saw: Airi crawling across my torso licking up my cum.

I gave her an innocent grin.

She sighed and came over. I was very interested to watch the hypnotic motion of big majestic boobs as she walked, only slightly disappointed that she held her arm as a bar across them for support, stifling their jiggling. She sat down on the couch cushion next to me and patiently waited until Airi finished, reaching out occasionally to wipe at my body when she caught some she had missed.

As Airi sat back, licking her lips and looking satisfied, Mom said, "Well I want this training to be meaningful so let's continue. I'm sure your brother won't mind and I have little doubt he'll get erect fairly easily. Just go ahead and take him into your mouth with him soft like that."

Airi did just that with a happy slurp as she realized there was still quite a lot of messy jizz all over my member. I reached over and fondled Mom's naked breasts, marveling at their incredible size and softness as my flaccid cock was gently sucked back to life. Seriously, was this not the best experience of my young life? Did I truly deserve this?

As I once again grew hard, Airi came off my cock with a lewd pop and abruptly asked Mom, "What about deep throating?"

Mom looked surprised, "Ah! You know that much?

She blushed, "I-I'm not actually...I guess competent with that skill. Hmm, perhaps that is a bit advanced. Let me-hmm, do some research and we'll have another lesson. I'm guessing learning something like that might keep your brother satisfied." She gave me a side-long glance and I shrugged with a happy expression. The thought of my Mom doing some internet research on that topic was so great and so was getting to do this again!

Over the next half hour or so Airi sucked my cock again with Mom even joining in for long stretches of personal demonstration or 'learning by observation' as she put it.

I think my Mom just really liked the taste of my cock....
