You try to help

Overwhelmed, you try to think of what to do, but the growing futa is impossible to ignore. She is getting hotter by the second, and your poor mind cannot handle it any more than she can. Without even thinking, your hands move towards her bulge, her hard cock perfectly visible under her absurdly stretched pants, already as big as your forearm and getting bigger.

"Yes! Fuck!" She shouts, her voice so much louder now. Her clothes start to tear apart, her shirt is the first to go, dropping down to the floor like a discarded rag, then her pants, ripping in two and letting her huge cock bounce free and slap you in your stomach hard enough to cut your breath for a moment.

"Please!" She shouts again, wildly humping you against the wall. Her overwhelming physical presence is inescapable, she is so much bigger and stronger now that you have no chance to escape, even if you wanted to. In fact, you can barely move, but somehow you manage to wrap your hands around her shaft.

Her cock throbs, a stream of pre leaking out. "God, yes! I'm so close already!" She shouts again. She is getting so big! You are staring at her abs now, while standing up! So perfectly sculpted you could grate cheese on them. And her cock is just scary, getting nearly as long as your entire arm and already much thicker than it. Both your hands cannot warp all the way around it!

But you try your best to satisfy the growing futa. Your hands go up and down, quicker and quicker, she starts fucking your hands too, her hips moving frenetically, while her growing balls swing and hit your arms. How big are they? How big is she going to get?

You get your answer when she suddenly stops moving and tenses up. "Ahhh!" She screams, and an avalanche of cum pours out of her cock and directly into your face. Your vision goes white, the pressure is intense, enough that you get your mouth full without even opening your lips. It feels like you are getting waterboarded with cum.

She has one last, giant growth spurt as soon as she cums, climbing higher and higher until her head hits the ceiling, hard enough to daze her. Her foot then slips in the pool of her own cum and she falls down, finally falling ****, or perhaps a quiet sleep, induced by the insane growth and orgasm.

You stare at the giant futa, filling up the floor. She is simply insanely hot now, the apex of futanari. Her body is perfectly shaped, covered in thick but feminine muscles, large boobs that are bigger than her head, and much bigger than yours, an ass so round and perfect an artist could not make a better job, shapely muscular legs that go on forever, and a massive cock that would make a minotaur feel inadequate, with a pair of giant balls that are already churning the next load.
