Thor's eye shoot open as Tony sinks down upon him, and he bites his lower lip.

When he finally opens his mouth again, it's to inhale sharply, and then exhale in a long string of words. "I am dead serious when I say this, Stark, but I don't know how much longer I'm going to be able to hold out."

Thor doesn't at all remember it, but his hands are somehow on the sides of Tony's thighs now. He loves those thighs.
