What to do when you get home... Games, watching something, a light workout, maybe just going straight to bed. It's been a long day, so going straight to bed isn't entirely out of the question. You would nearly be falling asleep walking down the street if it wasn't for the music you're blasting. You do know it's not a great idea to have both earbuds in and not pay attention to your surroundings at night, but you're a well-built guy. No one should try to mess with you. After all, if you're walking home, you probably aren't carrying a ton of cash on hand or anything like that.
You check your surroundings from the corner of your eye once in a while, and you could swear that you see someone closing the distance behind you. Turning around all the way and staring at them would only make it work, so you just pick up the pace a little and try to get home as fast as possible. For a minute or two, all seems well until you feel a pair of hands on your shoulders and a nip on your neck. You're frozen in place, no way someone is actually trying something. It's not like you've got much to lose, but it's certainly still scary.
"I don't have anything!" You blurt out, trying to slither your way out of the situation as you turn around to face your attacker. What you don't expect is to see a figure significantly smaller than yourself, and it's not some guy in a ski mask. It's a girl wearing a crop top and a short, tight skirt with fishnet leggings. "What do you want?" You ask, sounding plenty confused as to why you'd be getting such attention from a girl like her.
"Mppphhhh~!" Your yelp is stifled as the girl lightly wraps a hand around your throat, pinning you to a wall and kissing you right on the lips. She slides her knee between your legs, rubbing your crotch with her thigh while she forces you to make out with her. You're left completely stunned. What should you do? What is she doing this? You can't complain about having a girl make a move on you for once, but why in such a suspicious and forceful way?
While you can't tell with all of your clothes still on and your mind focused on the potential immediate danger, your body is already starting to change. It manifests as faint aches and sorenesses as your bones crack and your muscles shift beneath your skin. The process is gradual enough that you couldn't realize it is even happening unless you focus on it directly. As your tongue comes to intertwine with hers, you start to lose width off your shoulders, inches off your height, and muscles off of your frame.
"Pwwahh~ You're pretty hard already. You wouldn't mind some extra fun then, right? I'm sure no one else is around here at this hour." The mysterious woman insists. She isn't trying to take your money or anything, and you haven't passed out yet. Plus, it's not like you can really say no. You nod your head to agree, and she is sliding down your pants in no time. Your undergarments come off shortly after she teases your bulge some more, leaving you naked from the waist down in the middle of the night with a random stranger.
She doesn't leave you alone in that aspect, though. The woman lifts her crop top to reveal that there's no bra underneath, just big, plump breasts with puffy, erect nipples at their peaks. "Could I at least ask why you're doing this for me?" You blurt out when it is perhaps a better idea to stay quiet.
The woman carefully positions herself to get a perfect angle for a titjob, sandwiching your cock between her breasts effortlessly, only leaving your tip poking out. "Does it matter? I'm doing you a favor." She responds fittingly, only needing to bob her breasts up and down for a few seconds to produce enough precum to be used as lube.
You're left sitting on a bench on the side of the pathway, stifling your moans, trembling while getting a truthfully heavenly titjob. It's so good that you still fail to notice the extent of what's happening to your body, particularly to your head and face right now. Your hair is growing longer by the second, down past your ears, and then past your shoulders. Your nose is slimming while the sharpness of your jawline is softened out, prompting your lips to become soft and plump to match the rest of your feminizing appearance.
"Does that feel good? Having my huge, heavy, warm breasts completely engulf your cock? Does it make you excited to think about splattering your cum all over them?" Her sultry words sink into your brain, slipping your mind deeper into a state of lust and further away from your rational senses of caution and apprehensiveness. You let out a moan, telling her that everything she says is true, and you feel all of those things she asks.
Soon enough, you start feeling more. Some things a man shouldn't be feeling. Your chest gets hot, too hot. The heat quickly fades, though, being replaced by a strange tenderness and faint, radiating pleasure. Alongside that, you also feel some additional weight, fatty weight. It jiggles, unlike a muscle, whenever you move. Not much, but more than enough for you to notice. It only takes one glance down to see the light padding of fat behind your engorged nipples to realize that you're starting to grow breasts.
"H~Hey... Ghhhnnn~ What are you doing? Why do I have t~tits!?" You blurt out, trying to get her to stop for a moment and explain this all to you. You knew it; there had to be a catch. Why else would she be doing such a service to you for free? Your legs are too weak to run as she leaves you right on the edge of climax. Just the thought of giving up makes your muscles tremble and shake.
"Giving you the best body you could ask for. Breasts come with that, naturally. Don't you like mine? Isn't it tempting to imagine having a set of your own, so big and sensitive?" You could swear her voice has some sort of otherworldly disarming property. Her suggestions sink so deeply into your mind that you can't help but lust after the ideas she has implanted. As your chest jiggles and wobbles into perky C cups, the pleasure of their growth ramps up, making it even harder not to cum and keep yourself in control.
"I~I'm a guy... guys don't have... mmmmgghhh~ boobs!" You resist in futility. She already knows that the bite on the neck was all she needed. Everything else only makes the process faster and more fun for her. Unknown to yourself, you're starting to take on more of this girl's characteristics. Your skin color is shifting to a light brown tone, and the shape of your face is making all of the little adjustments needed to be exactly like hers, including the freckles on your nose and cheeks.
"You won't be one for much longer, so you don't want to worry about that. It'll feel so much better on the other side~" The woman coos while she keeps your cock encased in her cocoon of warmth as you have your metamorphosis into a being capable of so much more pleasure. As your breasts swell into D cups, the bliss of their growth chips at your mind. You're starting to want this, even if you didn't moments ago.
"So what about it? Are you satisfied with what you've got? Or are you oh so jealous that my tits are bigger than yours?" She teases, going slowly and sensually so you can feel how huge and soft they are with the most sensitive part of your body. She melts away your mind through your cock until you can't help but blurt out what you're thinking.
"Yes, I am. I want my breasts to be bigger, at least as big as yours." Your feminizing, meek voice mutters. The admittance is enough to make the woman happy, and she finally allows you to cum, going for one final motion with her breasts. Their slippery, warm softness slides down your shaft, earning a geyser of sticky cum splurting onto and between her cleavage. "F~Fuuuckkk!" You cry out, feeling your breasts swell up another cup size or two while you cum. Feeling the weight being packed on is orgasmic in and of itself.
"Looks like you're close, but not quite. How about you prove your manliness is enough to be worth my time? Then you can have what you desire, darling." She taunts, turning around to face away from you. Somehow, she manages to insult your masculinity while you want to become like her at the same time. Who knows how, but it works. You're desperate to prove yourself, and you place your hands on her hips without question.
She slides down her skirt herself, doing so slowly to accentuate the wideness of her hips and the thickness of her ass. All that's left is the fishnets underneath, which you're more than happy to tear to make space for your cock to fit. Her pussy is puffy and dripping already. There's only resistance from her slit from the initial penetration. It feels like it's sucking your cock inside immediately afterwards, making it effortless to fuck her as hard as you can. Her moans getting louder and louder, combined with your tits bouncing wildly as you thrust, gives you the motivation to put all of your effort into this.
"Unngfff~ Shit! You've gotta... haaaahh... really want my tits!" She says through moans, teasing you even while you're fucking her brains out. You notice a familiar sensation to what you felt with your chest has been brewing around your lower body. It doesn't take much to realize how waist and hips have been trading width, the latter getting the better end of the bargain. They give plenty of room for his already thickening ass and thighs to properly fill out his increasingly womanly frame.
With every slap of your groin against the woman's ass, you can feel your own jiggling more and more from the impacts. That, combined with the blissful growth, makes it difficult for you not to be a quickshot while having sex for the first time in a while and the last time ever as a man. Not that you care, feeling your ass and thighs jiggle bigger while the promise of having huge, sexy, sensitive breasts lies right before you is too tempting to keep your manhood for any longer.
Every thrust brings you closer to the edge. It feels like climax is only one or two thrusts away, but you manage to keep going, and keep growing your thighs and thighs fatter and thicker with every passing second. It feels strange but erotic and pleasurable to have your ass be so heavy and plump. You know for certain you're going to have a hard time fitting into pants with these proportions, but that's all part of the fun.
Eventually, your body has had enough. The woman's magic that's preventing you from cumming too soon falters, and you give her one more powerful thrust before you dump a massive load of your seed inside of her. "Fuuucckkkk~ I can't stop it!" You moan in a voice perfectly mirroring her own, feeling your throbbing shaft shrinking inside of her pussy while you dump all of the cum you have left inside of her quivering womb.
"Let it all out, fill me up until I can't take anymore!" The woman lustfully demands, her pussy milking as much from you as it can possibly manage, taking away more of your manhood in turn. Your head is spinning in the clouds. The only thing you can focus on is the constant, overpowering bliss while the last of your cock slurps away between your legs to become your new, plump, puffy sex.
You're exhausted, a near replica of the girl before you. Not quite as curvy, and notably lacking any of her tattoos. Noticing how tired you are, and the fact that this whole process is almost completed, she gets very close and ruffles your silky black hair. "Good girl... goooood girl. You're such a good girl for wanting such big breasts and a curvy ass. I think I good girl such as yourself deserves exactly what she wants."
What happens next is something you can't manage to describe. The only way you can put it into words is her warmth melting into you as her form becomes ethereal and translucent. Her ghostly form and its heat merge with your body, and the effects are immediate the moment the merging is complete. As the last of her body enters yours, your body is wracked with a crashing, surprising wave of bliss as you get exactly what you asked for.
"Ghhhnnnn~!!" You groan as your pussy twitches and squirts while you arch your back and push your chest out, feeling your chest surge forth and packing on even more supple, sensitive mass. Your nipples tingle as they get bigger and puffier alongside your tits, quickly becoming too big for your cup size. That problem doesn't last long as another surge of blissful expansion comes swiftly after the first, finally getting your tits to match the size of the mysterious woman's. Still, your lustful mind hungers for more. She was so curvy, so sexy, but your brain is too tempted by the desire to become even curvier and more sensitive.
From the power of your own mind, you manage to force your breasts to gain another two hefty cup sizes. Your nipples and entire breasts tingle with anticipation and sensitivity. Your hands hover nearby, almost touching. Even through your lust, you're still scared to feel how sensitive this body has really become. "Mmghh... shit..." You mutter underneath your breath.
You bite the bullet and give them a squeeze, cumming once again and sending your body reeling into another wave of growth. Your ass and thighs jiggle while various tattoos the woman had inscribe themselves upon your body, further molding you in her image. Your legs quiver and tremble, and you're forced back to the ground while your ass spreads further against it from all of the extra mass being packed on.
The very moment your second climax fades, you can't help but get started on the next one. You sink your fingers into your pussy and rub your clit at the same time, taking in all of the novel but at the same time familiar, enhanced bliss of this body. You should certainly be getting home by now, but one more little session shouldn't hurt.
