Giving in to this body's impulses

added by Berk92 16 days ago AP Race change Body swap

You rub your new strange face with Michael's burly fingers, wiping off the few sweat drops and taking yet another feeling of this black man's face, of his scrubby 1 day beard, of his wide nostrils and pudgy lips.

And of course...

Of this 10 inch rock-hard black dong you now have to deal with, which is irradiating a rather uncomfortable warmth all along your crotch and groin and is making your mind go wild. You think about your neighbor, that sexy black MILF called Janelle, you think about that wide pair of hips and plumpy ass. You remember how she was looking at you... at Michael's body.

"Aaaahhh... I really want to fuck her..." You say in that deep husky voice that you still can't get used to, all while impatiently rubbing those burly and tense forearms.

You want to see this huge piece of black meat you now possess disappear between Janelle's plump buttocks, you want to see her squirm under you. How will she react? Will she like it? Will she...?

You clench your teeth and immediately put Michael's boxers back up, trying in vane to tuck his enormous rock-hard dick back inside the fabric.
It doesn't take long for you to abandon your effort as a lost cause, so you reluctantly allow Michael's thick obelisk to poke over the rubber band while trying to cover the thing with a t-shirt as best as you can. You can feel that uncomfortable warmth pressed against your belly, reaching way past Michael's navel. But you try to ignore it while putting some pants on, showing a conflicted expression through the whole process.
This body's libido is already making you crazy enough, to the point that you feel yourself close to cumming even though you have done nothing other than pissing and fantasizing.

Without wasting any more time, you grab the keys and step out from your door. Then, after 20 seconds of almost running, you're already in front of Janelle's door.
Your breath is already quickening and you feel the first drops of sweat over Michael's forehead, his vigorous heart hammering your chest from the inside, and the black man's dick already leaking precum in anticipation while visibly staining the t-shirt. You gulp down at the itching feeling that covers an area way wider and larger than wht you're used to. But you quickly pull yourself together and ring.

After half a minute that feels like an eternity, you finally hear some little steps approaching the door.

"Who's that?" Janelle's distinctive voice asks from behind.

"I'm J-...uh..." You hesitate. You almost said your real name by mistake. "I'm Michael" Your finally say in a confident voice.

The door immediately opens, revealing the plumpy figure of Janelle's curvaceous body tightly tucked in her sports clothes. She is wearing a pair of leggins that seem barely able to contain that blessed booty of hers. From your astonished point of view, that piece fabric looks like it's about to burst from all that black meat pressing from underneath, like the world's most wonderful piņata.

And you're desperate for a piece of that candy...

"Hey, Michael" She greets me with a wide smile. "Boy, I thought you'd visit eventually, but I never thought you'd get me right in the middle of my morning routi..." she suddenly shut her mouth, looking down at the long bulge deforming your t-shirt and pants "...Oh."

She looks back at your(Michael's) face while you can't take my eyes off that wide chocolate cleavage. Are those E-cups? Maybe even F?

"So you comin' to get a piece of me, huh? Is that what you wanna say, big boy?"

Since she can read your mind, this will make things easier, so you look at her eyes for the first time and start talking.

"Babe, right now I'm feeling as smooth as a piece of sand paper, so I'll be direct with ya. Your annoyingly sexy ass has been troubling me since I saw it wiggle for the first time. And because of it, the first thing I did in my new apartment was making a total mess off the livingroom floor" You say in one go, your voice so deep it makes your stomach vibrate.

"And after I woke up this morning, this 'little' friend of mine..." You say, glancing down "...decided that he wanted the real thing and couldn't wait for another minute. Long story short, things have escalated, and now I feel like I'll go mad if I don't fuck your brains out until you lose the hability to walk straight."

You step forward, Michael's heavy body swaying a little bit.

"So what do you say, girlie? Are you ready to take some action?"

"Uh..." She hesitates, looking like she is taken aback.

You look at her with almost bloodshot eyes. If she says no, you don't know if you'll be able to contain yourself. This body's frightening libido is actively challenging your willpower. To the point that you might end up jumping at her like a beast and end up commiting a crime.

But after 8 painfully long seconds.

"Le me... take a shower first."

You stare at her in disbelief.

"...Sure."

Once she's already made her decision, Janelle seems to regain her composture.

"Make yourself at home, big boy. There's some beer in the fridge if you want a sip."

She invites you in and closes the door behind. You keep looking at her every movement while she does that, Michael's eyes following Janelle until she disappears in the bathroom.

"Haahhh... What is wrong with me? God damn it, Michael, weren't you supposed to be in your forties? Just chill the fuck out, man" You say to this body you got swapped into.
As a man in your twenties, you already have a long history of horny moments in your decently active life. But this is literally the first time you ever came so close to acting like a... like an animal in heat. Michael's libido is starting to frighten you. And you'll be stuck as him for an entire year...

You walk to the kitchen sink and vigorously rub cold water over this black man's face you now possess, almost as if trying to clean your thoughts. But the moment the noise of Janelle showering comes to your ears, you can't help but instantly imagine what is happening behind that door.
And these bulky dark balls nestled between your muscular legs suddenly twitch in response, in a way that your original body never did. And that twitch makes a mess of your whole train of thoughts.

That's it.

You immediately take that shirt off, revealing Michael's bulky body that's slightly chubby on the belly. After that, you throw away pants and boxers to a random place in Janelle's living room. Then, you stop for a moment, feeling the gush of cold air caressing Michael's(now your) massive black dong, now totally wet after all this time of constantly leaking pre-cum. You take a deep breath in a last attempt to calm yourself. But after it obviously fails, only a single course of action remains in your mind.

You start walking to the bathroom where Janelle is at, your decisiveness making your bare feet stomp the floor with an unusual sense of heaviness. Then you open the door, finding yourself suddenly surrounded by steam and the noise of water running. A pleasant soapy smell fills the whole room.

"Huh?" Janelle asks, surprised. Her voluptuous figure looking slightly distorted through the shower screen "Michael? What are you doing here?! I'm not ready ye-..."

Before she finishes her remark, you open the screen in a complete lack of consideration.
And there she is: Her black and curly wet hair pushed against her scalp, falling around her astonished face without losing barely any of its volume. Both her eyes and mouth are wide open, and her lips are as big and full as human lips can possible become in a natural way.
But it's the rest of her body what your eyes devour the earnest. Her naked wet figure is like a dream of imperfections that forms the most perfect body under your sight. Janelle is a decently fit woman, clearly possessing a base of toned muscle solidly cemented under a bountiful layer of fat which is distributed in all the right places to make her plump body a feast for the eyes.

Janelle seems very alarmed, and she immediately tries to hide her large breasts behind her forearm while doing the same with her rather hairy crotch.

"Michael, WHAT THE FUCK?!" She yells at you, reacting to your intrusion like any woman would if a naked 240lb black man with a 10 inch raging boner irrumped in the cubicle where you're taking a shower.

"Sorry, Janelle" You say in an awkward voice, the same tone you've always used when, back in your original body, you greeted her at the hallway "But I don't think I can hold back anymore..."

"Michael, I'm fucking serious! Get the hell out before I call the... the..." Janelle stutters for a moment when she notices the black monster you're packing, now on plain sight and reaching way above the crotch area.

And Michael's shaft is indeed now itching and twitching more than ever at the sight of the woman's wide plump hips. You almost feel like it's gonna explode from all that pressure.

"Janelle, please..." You ask her, not exactly sure at how to proceed.
You showcase your already obvious intentions by grabbing your new itching dick. By now, the shaft is so thick and hard that Michael's burly hand can't even fully close around it.

"You a horny monkey or what?! That's it, I'm outta here." Still covering herself, Janelle walks around you and reopens the screen "Ya better prepare your ass for jail because I'm definitely calling the po-Huh?!"
Janelle turns her alarmed face back towards you the moment you suddenly grab her hips from behind. She was so exposed that Michael's hands were already moving before you even thought of it.

"You gotta be kidding me!!" She yells the moment she fells the whole length of your heavy black shaft sinking between her plump buttocks.
The slight touch of her wet exposed skin is like a brief taste of Paradise before the sense of urgency props your exchanged body to lower its muscular hips and nestle the round marble-like glans right between a particular set of folds that you can't see under Janelle's amazing ass. But it feels distinctly... welcoming, and especially warm.

"Hold on for a fucking second, Michael, chill out before things get out of control, alright?" Janelle says in a surprisingly calm and reasonable tone, as if she is trying to appeal to your common sense. "Look, it's not too late to talk things out. But you gotta understand that I'm not just a lowly whore you can take any time you wa-"

Despite her last ditch effort, your arousal is already past the point of no-return. So you project Michael's hips forward...
