"No." Another gyration of his hips against Sam's ass accompanied by a first upward stroke on his cock. "This ain't just about me. It's about taking care of you. You're just mad because you had a plan and now it's gone to shit."

Which, honestly, plans that hinge on Tony Stark having any semblance of his shit together often fail.

"You think you don't like it, that you don't like me, and that's alright. We got time. Your ass likes me." Pulling back enough so that Sam can feel that knot swell and catch inside of him, just to slam deep again. "Your wet perfect fuck hole likes me. The rest of you will come around."

He rests his chin on Sam's shoulder as he begins thrusting again. "Gonna be so good for you ya get wet just seeing me. Never gonna let that go to waste, either."
