Tony's body was warm and welcoming beneath his hands, and Steve was set on caressing everything; his pectorals, his nipples. Every scar, every curve. The blonde was getting louder with those noises. Particularly when he felt Tony's fingers opening his fly. A hand shot out from beneath that shirt, reaching to grab Tony's - not for the sake of stopping him, but to encourage him to go further. He pushed Tony's hand onto the bulge of his erection, separated only by the thin layer of his underwear.
An intense spark shot through him. He groaned and leaned heavily into the other man, the need to be touched only becoming worse with every passing second. It would be rude not to return the favor though, wouldn't it? So once Steve recovered from that wave of pleasure enough to do more than just react, his own fingers were fiddling with the closures on Tony's pants. With less skill and grace, granted, but Steve was plenty eager.
