[F4Futa/TF] I need a subby girl with a big dick who loves having huge boobs shoved in her face.

NSFW

There's gotta be some of them out there, right? I'm just craving this particular combo of things right now, though I'm not sure why.

The introduction blitz round: hi, I'm Izzy, I'm gay, I date cis and trans women, I'm cool with dick as long as it's attached to a pretty girl, and I have a bit of a breast expansion kink.

I think we could work those things in together with a little bit of magic. Like, cumming inside me makes my boobs grow, that sort of thing. I'm really into not-fully-controllable transformations, especially resulting in clothing damage or the risk of public embarrassment. The idea of sitting on your cock, milking it with my velvety little pussy, then busting out of my shirt so you have no choice but to suck on the marshmallowy boobs filling your vision… gets me so damn wet I can't believe it.

Izzy let out a guttural sigh as she sank down onto Taylor’s shaft, her eyes rolling back in her head as she felt it pierce her core. “Oh, fuck,” she whimpered, her body trembling from head to toe at the size and heat of the invader. Her ample chest already strained at the sundress she was wearing, and the deep breaths she found herself taking to steady her mind only made the relationship between the two more fraught, more akin to the ocean against a bulkhead. “Fuck,” she repeated dizzily.

“Fuck!” Taylor echoed, squirming under Izzy’s hips. Her face was already full of her girlfriend’s cleavage, and her hot, tight pussy was clinging so greedily to her cock that she struggled to form words. “Izzy, mmffucckkk…. ‘mgonnaaaaa—”

”Yes, baby, fill me!” Izzy moaned, not caring about her lover's shockingly premature orgasm as it bubbled up unstoppably within her. On the contrary, she took it as a compliment as a pool of heat flooded her womb, tingling with magic that drew it deep within her. Her breasts matched that very sensation, a pins-and-needles feeling that made her nipples stand on end, poking through the thin fabric of her dress. “More!” she begged, rolling her hips on Taylor’s lap as she felt her neckline grow tighter and tighter, almost cutting into her soft skin.

Taylor could only groan and gasp, her cock pumping rope after rope into Izzy’s greedy womb. And the whole time, her cleavage grew deeper, her tits swelling through several cup sizes before finally — *pop* — a button gave way and her vision was filled with pale, freckled tits at point blank range, heaving with exertion as Izzy shrieked happily, still grinding her ass in Taylor’s lap.*

Uhm. That might be the dirtiest prompt I've written. Y'all have corrupted me.
