What's next?
Tiffany's room
Tiffany’s bedroom door closes behind you with a thud. You take a moment to analyze the state of her room and find much of it changed from how it was before she’d moved back in. She’d only moved back into the house less than a year ago, but it seems she’s already gotten rid of most of the decorations she had there during her high school years. All the posters of her favorite boy bands, the insane amount of makeup kits she’d used to have – all gone, in a dumpster or landfill somewhere. She kept the funky lava lamps, though. Two of them are on right now. One glows dark red and the other a whitish yellow, like the sun. They sit perched upon her dressers.
The room is rather plain compared to what it used to be, and you find that much more appealing. You prefer neat, organized settings over chaotic ones. You suppose that’s one of the reasons why you and your sister have struggled to get along. After she’d gone into high school and started miring herself in whatever new fancy or fad was in vogue at any particular moment, she’d never invited you to spend time with her here. Other, less closely related people were allowed in all the time, whether they were boyfriends or just friends. Aunt Leslie’s daughter, your cousin McKayla, had stayed in Tiffany’s room when she and your aunt and uncle stayed over a few years ago. But not you. You were the one person who was forever barred from Tiffany’s inner sanctum. The one person who ever truly displeased her.
People seemed to have always really liked Tiffany, and they’d had no problem getting along with her. Not like you. You prefer the calm, ordered solitude of your room to stressful social situations. You suppose that makes you seem judgmental or aloof to others, and while to some extent that’s true, it didn’t mean your family’s tacit rejection of you didn’t sting. Try as you might to be a self-contained individual, you’re still human. You still crave the warm company and acceptance of others, especially in those moments you want nothing more than to cut off all outside contact with the world.
Now, as you look into your sister’s pretty emerald eyes, you know something fundamental has changed about your relationship. Gone is the casual dismissal of anything you might say or feel. Instead, she seems to want something from you besides your absence, and thanks to the instructions you’ve given her under hypnosis, you have a pretty good idea what she wants.
“So,” your sister says. You look at her body up and down. She practically preens when she knows she has your attention. She leans towards you slightly, drawing your eyes to her deep, expansive, pale cleavage. Her teardrop breasts dangle tantalizingly within the confines of her loose shirt.
“So,” you openly ogle her breasts now, secure in the knowledge that while you didn’t accomplish everything you set out to during her trance, you’d done enough to make her crave your attention, especially in a sexual context. She doesn’t admonish you for staring. If anything, the smile on her face has only grown. She bites her lower lip and sighs happily.
“You like what you see, shithead?”
You shrug, the insult rolling off you like a drop of water. You’d called her much worse and been called even worse things in turn.
“I don’t know. I mean, you’re hot, don’t get me wrong, but I can’t help but feel like something’s missing.”
Her smile dies almost instantly. Her green eyes widen slightly and for a moment you think you glimpse a flicker of panic within them. You only barely resist laughing at how easily it is for you to damage her self-esteem now. She’d been doing it to you for the last half decade at least. Now, if you want, the shoe could be on the foot.
“W-what do you mean, ‘something’s missing’? I’m right here in front of you. what else could you possibly need?” Tiffany says, her tone a strange mix of anger and timidity. Her eyes are wide and ****, and you can’t help but empathize with the pain you see within them. Try as you might to forget sometimes, it’s impossible not to recall that you’re her brother and she’s your sister. You’re supposed to look after her, to protect her from the big bad world. Even if she’s the older of the two of you, you’d always do your best to keep her safe. Make sure she kept her scheduled appointments, ate breakfast, and made it to school on time. She’d hated you for it.
A not-insignificant part of you wants to say you’re sorry. To pull your sister into a hug, forget all about the changes you’ve made to her mind, and apologize for being such a distant brother. You chalk it up to some inner weakness you’ve yet to overcome, but the feelings are there regardless.
You set your jaw firmly. It doesn’t matter what you’ve done. You won’t hurt her in any way that’s permanent. She’s your sister and if you’re going to rewrite the way she sees the world, you’ll at least make sure she’s happy with the changes you’ve made, first among them being her feelings towards you. You want to be her everything. The person she can lean on when she’s lonely or scared or sad. You’ll give her more love and affection than Rick ever could, and provide your little nephew Ronnie a life where he’ll want for nothing. Maybe as time goes on you’ll give him a few half-brothers and sisters to keep him company.
The thought causes your cock to harden. You picture Tiffany pregnant again, her already large breasts swelling even further with milk. You see her cradling a cute baby bump, her hands rubbing it lovingly as she whispers sweet nothings to her unborn child. You imagine everyone else congratulating her on her second pregnancy, unaware of the fact that the child was yours.
Your lips tremble into a smile. Where were these thoughts coming from? You’d certainly never imagined anything like that before, but now that you have you can’t shake the thoughts from your mind. You suppose the nature of your ability has something to do with it. Before you’d met Charles, Tiffany would never have seen you as anything but the younger brother she’d long hated. Now, you can whisper into her mind, reshaping it and everything she knows and thinks and feels and believes. You can make her love you more than she’s ever loved anyone. You can make her crave your seed inside her, and have her believe that bearing your offspring would be the greatest thing she has ever done.
“John, you there?”
Tiffany waves her hand in front of your face.
You blink and shake your head, dispelling the litany of dark thoughts that had broken free from some abyssal corner of your mind.
“Yeah. Sorry,” you mutter.
“It’s okay,” Tiffany gives you a strained smile. “Um, you were saying something was missing?”
Nodding, you think about what to say for a few moments. You want Tiffany to feel appreciated by you, but not too much yet. You want to see her naked first and have her believe she has to do more than simply exist to earn your appreciation.
“Well, first off, you’ve got all those clothes in the way. That’s a huge problem for me. When you sent me that picture earlier, I assumed you wanted to show me your naked body. That’s why I came home so fast. If you aren’t going to take your clothes off then I might as well leave now.”
Tiffany’s eyes widen. She grabs your arms with her hands.
“No, don’t leave! Please!” She looks down at herself in surprise, as if she’s only now realizing that she’d been clothed this entire time. “I-I’ll take everything off. I swear, just don’t go. Look, I’m taking my shirt off now.”
She hooks her hands into the bottom of her shirt and pulls it upward, exposing her creamy, soft stomach. She’s somewhat chubby, not in the same shape she was before she’d had Ronnie, but she isn’t obese either. Within moments, the rest of the offending garment is lifted above her head, and you stare with wide eyes at her breasts which have been revealed to you in person for the first time.
They’re huge, bigger than you think they’ve ever been thanks to Tiff’s pregnancy. Her pink nipples are small compared to the enormity of her breasts, but they’re hard, standing out proudly as if begging for your attention. They’ve certainly got it.
Tiffany notices your interest and smirks, her confidence seemingly returning. She gives her chest a shake. Her big tits wobble from left to right. You watch them move.
“Wow,” the word escapes your lips almost of its own accord.
Your older sister puts her hands on her hips proudly.
“Aren’t they amazing?” she says. “Rick says they’ve gotten a little too big since I got pregnant, but I like them.”
She gives her chest a shake, causing her breasts to wobble and jiggle delectably with her movements.
You try not to let them distract you too much. With a snort, you say, “You’re kidding, right? Rick thinks they’re too big?”
Tiffany shrugs, but you can tell from her body language that it bothers her a little.
“Yeah. Well, he says he’s worried about me getting backaches from them, but I haven’t felt anything like that so far.”
“I’m glad to hear it,” you say.
Tiffany smiles warmly. She gives her breasts another shake, and they jiggle to match her movements.
“Why don’t you come and feel them? They’re so soft. You could just stay here all day and feel them.”
“All day?” you croak.
Tiffany’s smile widens.
“Mhm. All day. Everyday. As long as you want. We just gotta make sure nobody figures out what we’re doing. You may be willing to bre…” her mouth droops open slightly and her eyes take on a distant, far-off look. “…break a major taboo,” she licks her lips. “But most people are really judgmental, especially Mom and Dad. They won’t understand at all, so this’ll have to be our little secret.”
You nod, but decide to test her further.
“What about Rick? Wouldn’t this be like cheating on him or something?”
Tiffany nods.
“Yeah. Probably. But… I don’t know. I think I remember liking the way he looked at me, but now it just feels like he thinks I’m a fat pig. Oh, he’ll still have sex with me, but I know deep down that he doesn’t really appreciate my looks at all. Not like you,” she grasps your hands in hers and brings them to her breasts. You give them an experimental squeeze and find them to be incredibly soft and warm.
“See?” she gestures toward your hands before meeting your eyes. “I can tell you love my tits. Like, really love them. Like it doesn’t matter how big they’ve gotten, you just fucking love them and I can’t get enough of it. Holy shit, that feels amazing.”
“Yeah?” you give her breasts another squeeze. “You like that?”
“Mhm,” your older sister moans.
“You like having your brother grope your big tits?” you prod her.
She swallows and nods.
“I want to hear you say it. Tell me how much you like me touching your tits.”
You grab her nipples and pinch them between your fingers.
Tiffany whimpers.
“Ah!” she closes her eyes for a moment. When she opens them, her eyes are hazy, like she’s under the influence of some ****. “I… I fucking love it when my brother feels up my tits. It’s amazing.”
“Is it better than when Rick does it?” you say.
She nods rapidly.
“Hell yeah. A million times better. My fucking fiancé doesn’t make me feel good at all. Not like you do…” her hands find their way to your arms. She massages your skin before moving them up to your shoulders and then your chest.
Your eyes widen.
“W-what are you doing?”
She smirks.
“Returning the favor,” she replies matter-of-factly. Her hands find the bottom of your shirt before moving under, stroking and prodding your bare skin as you continue to grope her large breasts. “Hey. Since when do you work out?”
You sigh and roll your eyes.
“Since I decided I didn’t want to die of heart disease before age fifty?”
Tiffany raises her eyebrows. You shake your head, shooting her an irritated scowl.
“What? You think just because I don’t go out and party every day that I wouldn’t care about staying in shape?”
“No,” at your questioning look, she shrugs. “Well, maybe a little, but what I was wondering is if you’ve got a decent body, why do you hide in your room all day? Don’t you want someone to appreciate it and tell you you’re handsome or something? I know for a fact that there are plenty of girls who’d love to have a boyfriend who keeps himself in shape.”
You smirk, leaning slightly into her space.
“You think I’m handsome?”
Rather than retreat or be embarrassed, your sister nods simply.
“You know what? Yeah. You’re pretty cute, actually. And I really like how hard your chest is. So nice and strong.”
Huh. You’d expected her to just soak up all the “appreciation” you’d been willing to show her. You hadn’t expected her to want to reciprocate at all. She’d never struck you as the type to want to do that, but maybe you’ve been unnecessarily harsh in your perception of your sister. You’d be lying if you said you didn’t like what she was doing or the way her eyes seemed to light up at your reaction to her marveling at your body.
Shrugging, you take your hands off her breasts for a moment.
Tiffany gives a frustrated whimper, but her entire expression changes when you grip the bottom of your shirt and pull it over your head.
“Hmmm. Nice.”
She stares at your exposed chest for a long moment before putting her soft hands on you again.
“Can you grab my tits again, please?” she asks, her eyes looking up at you.
You make a show of considering her request before nodding.
“Well, since you asked so nicely…”
Tiffany smiles as you rest your hands on her breasts again. You poke and prod at them for a few minutes before returning to outright groping them. Your fingers sink into her plentiful titflesh whenever you squeeze. Tiffany lets out throaty moans as you do so, an ever-present smile on her lips. She keeps rubbing her hands up and down your chest, cooing softly when she pinches you.
You aren’t in what most people might consider to be incredible shape. Even if you exercised rigorously and had a diet to match, you’d never had the build to become truly muscle-bound like the men who’d been in a few of Tiffany’s posters. You have what some people call a wiry frame, which you maintain through regular exercise and intermittent fasting, which you’re much more grateful for now. Tiffany might have been trying to tease you earlier about wanting girls to like you and call you handsome, but you can’t shake the notion that she’d been right and the excuses you’d told yourself were just that.
The two of you stand in front of each other, feeling each other up for what feels like ten minutes. The novelty of feeling Tiffany’s breasts fades somewhat, and you expand your groping to include the rest of her chest. Her belly and her arms and her shoulders. She giggles when you reach her belly button.
“S-stop it! That tickles…”
You trial a finger over her belly button again, and she retreats slightly to get away from your teasing. Her cheeks are flushed cutely.
“You’re such an asshole. I told you to stop,” she mutters, but moves herself back into range of your hands. You grab her breasts again and give her nipples a tweak.
You let your eyes wander lower to her thick thighs and what’s between them and behind them. Tiffany notices your wandering gaze and smiles.
Without a word, she grabs the waistband of her booty shorts and lowers them, dragging her panties along with them and exposing her thick, creamy thighs.
You stare at her, marveling at the sheer beauty of the woman before you. Her skin is pale and flawless, with nary a blemish marring her features. She spreads her legs slightly, and you glimpse the pink lips of her pussy. A cute tuft of red hair adorns the top of her vagina.
Incredible. Your sister is utterly ravishing, not that you’d risk telling her that just yet. You need her to work for your appreciation, after all. But wow. Mom, Sharon, Marissa, and Vanessa are all amazing and beautiful MILFs in their own right, but as you stare at the voluptuous red-haired, green-eyed beauty in front of you, you think she might just be the most beautiful woman you’ve ever seen personally. In that moment, you know that in spite of everything, you need to have her. You will have her. She’ll be yours one day, completely and utterly yours.
Her eyes stare into yours searchingly, like an Olympic diver waiting to hear the verdict of her performance from a judge.
You give her an appreciative smile, a verdict on its own. She smiles back, leans forward, and kisses you. It’s chaste, and only lasts a few seconds, but the impression of her soft lips lingers on yours like a mark.
“Why’d you do that?” you ask, keeping your tone level so as not to seem judgmental or angry.
She shrugs.
“To say thanks, I guess.”
“For what?”
Another shrug. She crosses her arms beneath her big breasts, pushing them upward.
“I don’t know. Being here, I guess. You make me feel amazing, you know that?”
“I do?” you mutter.
“Mhm,” she hums, her green eyes staring into yours. “Most guys only pretend to like you so you’ll sleep with them, but with you, it’s like I’m the only girl in the world.”
You lower a hand, tracing it down her belly and abdomen before moving it between her legs. Her eyes widen as you touch her pussy for the first time. It’s warm and surprisingly wet. You find her clit and press against it with your thumb.
“Holy shit.”
Tiffany gasps and clenches her soft thighs, trapping your hand against her pussy. Her cunt pulses slightly against your hand.
“H-how am I making you feel now?” you whisper.
“Still amazing,” she murmurs, looking up at you with half-lidded eyes. “I can’t believe my own brother’s touching my pussy. I can’t believe I’m enjoying it! God, I’m so fucked up!”
“Hey, if you’re fucked up, then so am I,” you say. “So don’t worry about it. I won’t judge.”
She chuckles.
“Good point. I guess we’re both a little fucked up in the head.”
You take advantage of her distraction to insert your index finger into her cunt. Her slick inner walls spasm slightly before clamping down on your finger.
“Oh fuck…” Tiffany gasps.
You smirk back at her.
“Looks like we just broke another taboo,” you say, and resume rubbing your thumb over her clit.
She nods, biting her lip.
“Mmmm, I guess so.”
Her hands resume massaging your chest, but they start wandering lower. Her fingers tease at the waistband of your shorts. You keep rubbing her clit and start moving your index finger in and out of her slippery pussy. You’re rewarded with your sister’s hot moans and gasps, and you can’t help but feel amazing at being able to elicit those reactions from her, but you want more. You always want more.
“Hey, can you do something for me?” you ask.
Your sister stares at you for a few seconds before replying.
“Sur- ah!- but don’t stop – oh shit! – d-don’t stop rubbing me down there, okay? It feels really fucking good.”
You smirk.
“I wouldn’t dream of it. Now lie down on the bed and spread your legs. I want to see all of you.”
Her pussy tightens around your index finger, and you have a feeling that she really likes the idea of spreading her legs for your viewing pleasure.
“Okay,” she smiles.
Your sister backs off obediently, and you follow her, keeping your hand on her pussy. She stops walking when the back of her legs meet the bed. She lowers herself down, her thick thighs squashing outward against the light blue comforter draped neatly over her bed.
She scoots back until she can rest her back against the many pillows she has propped up against her headboard. Then she spreads her legs.
You stare as you get a good, unobstructed look at her pussy for the first time. It glistens slightly in the light of the room. You lick your lips. How many times had you imagined something like this happening before?
Your hot, voluptuous older sister is lying on her bed in front of you, naked as the day she was born. Her green eyes stare at you expectantly, willing you to make a move.
“You’re beautiful,” you say.
Tiffany’s face flushes a delightful shade of red that almost matches her hair.
“Gee, thanks. It’s strange, a lot of guys have said that to me before, but you’re the first one who seems like they actually mean it,” she opens her legs a little further and places a hand between her legs and starts rubbing her clit. Her face scrunches up, as if she’s frustrated about something. “Now come on. You said you were gonna keep playing with me down there.”
You grin wolfishly.
“I did, didn’t I? But you didn’t say the magic word.”
“Please?” she asks.
You quirk an eyebrow. Your cock throbs heavily in your pants. Fuck. You want nothing more than to take it out and shove it in your sister’s pussy, but you’re not sure she’ll allow it yet.
“Please what?” you say.
Her face scrunches up a little further. She glares at you for a moment before clenching her fists and taking a deep breath to calm herself. Hm. How interesting. Usually Tiffany had a pretty mean temper when she didn’t get what she wanted. Now she’s exercising more self-control than you’ve ever seen from her. She rubs her pussy impotently and groans.
“Please get down here and play with my pussy,” she inserts a finger into her cunt and starts fucking herself. She lets out another frustrated groan.
You shrug, trying your best to look nonplussed. It’s extremely difficult, however. If you’d tried this before you’d had sex with Marissa or gotten a blowjob from Sharon, you doubt you’d have been able to resist her at all.
“It doesn’t seem fair that you get to feel good, but I don’t. You mind if I take my shorts off?”
Her eyes fall on your crotch almost immediately.
“I-I don’t know…” her finger picks up the tempo, pistoning in and out of her wet pussy. Her huge tits jiggle with her movements.
“Oh come on, we’ve already broken a few taboos. What’s one more?”
“Ahn…” she inserts another finger in her pussy. Her eyes are slightly misty now. They stare between your legs. “Fine. Do it and get down here. Please. I can’t fucking wait any longer.”
You waste no time unbuttoning your shorts and pulling them down with your boxers. Your hard cock springs free. Your sister’s eyes widen slightly.
You don’t give her time to stare at it, however, and you crawl onto the bed on your hands and knees. You move between your sister’s legs so her pussy is mere inches away from you. She pulls her hand away from her pussy, allowing you unrestricted access to it.
You reach for it with both hands now, spreading her pussy lips so you can get a view at the pinkness inside. Her inner pussy walls pulse and clench. It’s hard not to imagine your cock inside there, but one thing at a time. You start rubbing her clit again with your right thumb. With your other hand, you insert a finger into a pussy up to the knuckle. Your sister gasps and squirms on the bed.
“Holy fuck,” she hisses.
You spent the next few minutes playing with her pussy. You end up inserting more fingers into her tight cunt until three of your left hand fingers are buried inside her. You move them in and out of her pussy, fucking her with your fingers. With your other hand, you keep playing with her clit, enjoying the way her body spasms and twitches whenever you pinch that little nub.
Her tits wobble and jiggle as she moves in tandem with your ministrations. She even starts playing with her own breasts with her hands, squeezing them and pinching her nipples when it becomes obvious to her that you enjoy it.
It’s all too much for her.
“John, I think I’m gonna cum,” she says. “Oh fuck, I’m cumming!”
She spasms again, thrashing on the bed. Her tight cunt clenches even tighter around your fingers as she orgasms. It lasts a little less than a minute. She sighs.
“Wow,” she mutters, looking down at your hands as you continue rubbing and playing with her pussy. She looks up at you again. Her eyes are misty and wet. “That was fucking amazing. I don’t think I’ve ever felt this good in my life. Do you, um…” she glances down at your cock. It twitches and throbs and you can’t help but feel frustrated at not getting off like she has.
“What?” you ask.
“Can I touch it? Your cock, I mean,” she licks her lips and swallows nervously.
The two of you stare at each other silently, and for a moment the room is so quiet you can hear your own heartbeat.
You nod.
“Uh, sure. Trade places?” you ask.
Tiffany nods silently, pushing herself up and shifting so she’s on her hands and knees. Her big tits dangle freely beneath her, swaying as she crawls to the other end of the bed. You catch sight of her juicy bubble butt. It jiggles as she crawls, and you can’t help but imagine it squishing out against your abdomen as you fuck her doggystyle like you did Marissa.
You lie down on the bed in the same position Tiffany had been. The comforter and pillows are slightly damp with her sweat and juices. Your hard cock sticks up proudly, as if vying for Tiffany’s attention.
Your sister, for her part, just watches. She’s kneeling in front of you now, her hands clasped atop her thighs. She makes no move to touch your penis.
“If you’re having second thoughts, we can stop. It’s no big deal,” you murmur, giving her a gentle smile.
She clenches her fists again. Her green eyes harden slightly.
“No. You played with my pussy and made me cum even though it must have been so hard for you to break that taboo. I won’t let my little brother outdo me,” she says, her voice firm.
She reaches her right hand out and grasps your shaft.
