That scream captivates all his attention, breast heaving as she takes what she wants from him. His fingers move rhythmically at her behest, ministrations speeding up as he feels her movements deteriorate. "Ah!" he cries out, moisture prickling in his eyes when she pulls his hair. It causes pleasure to lick down his spine and pool at his belly, determined to hold off until he can watch her come. When her body begins to shake, her inner walls squeezing and milking him for everything he has, he knows he can't hold back. He wants to ask if it's okay, but when he opens his mouth no words come. This is it, this is the end, and when he feels her orgasm grip her fully he tumbles over suddenly himself, with no warning. Tony's labored breathing rises in the room, bucking his hips upward as the throes of his own end consume him. "Yes, fuck. Pepper... I love it. I'm coming." More pitchy babble from him when his voice returns, eyes squeezed shut as his hot seed spills inside her, gravity causing it to drip back down over his cock in a strangely sexy way.
