There's a bit of shuffling as Peter gets a good grip on her thighs and tries -- if not to help -- at least not to hinder her efforts to align them. This being a dream, there's no twinge in his back at lifting her weight, no uncomfortable poking as she guides him in. There's just the smooth, firm slide into her wet heat, Peter letting out a growl of satisfaction as he pushes all the way in. Muscles of his back flexing, he withdraws, then pushes again, slowly starting the familiar rhythm.
