Mommy Milf-A-Site! (Wing-it)

You have been transformed into an Onahole and are being used to fuck a hard cock. It starts off slow teasing your hole and just poking with the tip. There's no pain but so much anticipation. It's going to stretch you so- OH GOD. It gets in, a satisfying pop around the head. In and out just a little bit. In and out in and out. God you've never been this full. Your hips expand a little with every thrust. Your stomach buldges a little bit. The cock starts thrusting deeper bit by bit. It feels like it's under your chest nowwww. Fuck. Shouldn't this effect yOUR breathINg? Do you breathe anymORE? Oh God you're so fuLL UGGH. IS it going to rEACh your neck soON? Oh God there's so much throbbing hot cOck. Up you're hole, through your stOMACh, the tip pushing to yoUR NEEeeck. Your mouth gets forced open a little with that thrust, a mix of precum and lube beads up and goes back down, but then cOMES BAAACK FUUUGUHUGHUGHIG

PLAP

This is it. Time is barely a concept. There's so much to feel, this is the tension right before the cumshot. You're fully impaled , it's fully erect, you feel so full and so good. For just a split second the cock relaxes, ready to cum. Then, you feel it. You could swear as you feel this body filling cock harden, that you can feel it's load travel though it. Up past your hips, your stomach, your chest, your neck... As this is happening the mushroom tip expands and breaks past your lips. The tip is no longer inside you, it's free, edge of the head resting snugly upon your lips. A giant (to you) load of cum shoots out of it. It feels so weird, it should be shooting into you but instead it's shooting though you. You've never been so full but felt so needy and empty.

It happens again. The tension relief, the tightening, the second shot. Not in you, but frustratingly through you. The third shot, the fourth. God it feels so... it's so good but you just... you just need more.

Taking on physical traits of the sire or sires, depending on how many are pumping babies in them. Growing even more fertile with each birth, going from singles or twins on average to full sized litters with no signs of stopping. Developing a more compartmentalized womb in order to breed more babies from more sires, and feeling all the various offspring shift and move around as they grow snugly next to one another. More teats or full breasts in order to whelp those babies after they're born, producing so much milk that they need to be hooked to a machine just to make sure none of it is wasted.

Fear or uncertainty of all these changes slowly fading into content, even joy or excitement with every successful breeding and birthed litter. A perfect little breeder, maybe even made into an idol of fertility. Not that they would particularly care; all they really look forward to is the next virile cock to come and fill the recent vacancy in their gravid, ever fertile belly.

This is an intriguing scenario, anon!

Could be aliens, could be some magical scenario, but regardless of what's impregnating you, your body is being changed. You're slowly morphing into the perfect breeding vessel, and the longer it goes on, the more content you find yourself. It's like you hadn't really had a purpose to your life before these beings started filling your womb, and now you know that all you want is to keep making their babies.

How much more will your body transform? How much bigger will the next litter be? There's only one way to find out.

I've done a couple bustyboy things, but I'm not sure if any of them would really count as femboy BE.

Here are a couple I've done in the past:

Bratty Busty Boy Hucow

Just Two Dudes Having Fun

Making His Boyfriend "Jealous"

New Star of the Show

Wing-it for churin Players, before you interrupt your DM, think about the poor NPCs and Monsters who are being tossed and tumbled in the sea of your assumptions 😔

At the time, intentionally getting infected with the Bimbo Flu had seemed like such a good idea. The injustices of genetics that had left Jennica flat-chested and scrawny finally had a solution. In the throes of it, however, Jenni was starting to regret it.

Or, at least, she would be if it wasn't getting so hard to think.

"Hnnng.... I, like, don't feel so good..."

Pink fever settled around her mind, making it harder and harder to think. Jenni couldn't focus on the fact that her grey top was starting to strain and stretch over her growing titties. She couldn't spare the attention to her soft, full lips that ached to have something slid between them. The only thing that mattered was the deep, desperate need between her thighs. She couldn't even spare enough attention to enjoy the feeling of finally having a pair of big, soft, sexy titties. Looking at them just made her hornier and touching them, squeezing them, feeling the biggest tits she had ever seen bulge between her fingers, made her practically feral as their growth pushed out against her grip. Her breasts seemed to grow in flashes as Jenni faded in and out of consciousness—or, rather, what passed for consciousness for a 'victim' of the bimbo flu.

Jennica, and all her aspirations, had melted away. Only Jenni, with her full lips and her massive, growing tits remained. A needy, sultry voice moaned out of her.

Jenni was busty.

Jenni was growing.
