Peter huffed out a breath of warm laughter against Bobby's chest when he told him how good it felt to have Peter on top of him, he knew how that could be too, it was always nice to change the perspective, to shift things around and experience something a little bit different. He'd felt the same laying in the grass with Bobby on top of him, the warm weight of him was different and nice and yeah - he got that.
Like this though with his hands and his mouth on Bobby, taking his time to explore his body, teasing his nipples with his tongue and breathing in the scent of him he could feel a shift happening. Even as Peter enjoyed the way Bobby felt beneath him like this, enjoyed the way his body felt under his hands and the way he moaned while Peter worked his way lower, tempted to spend a little time the same way Bobby had.
"Hey," He said gently, turning his face just enough to let his lips brush against Bobby's arm, there was a little less of the easy confidence in Bobby now than there had been before, Peter wasn't always great at reading a room, but he knew enough to sense the nerves in Bobby now.
He pushed himself up again, and kissed Bobby again, less heated and a little more slowly, a little more carefully. "What's going on up here?" He asked, settling on top of Bobby once more, his hand stroking over his side slowly, "Not that I don't appreciate an offer of anything I want," He added, "But I'd kinda like to be sure you're going to enjoy the experience too, you know?"
