"More," she whispers, and tilts her hips so he can go deeper. He’s big, and he fills her completely, stretching her until she is on the perilous border between pleasure and pain. For just a few seconds, she’s afraid it will be too much, but her magic draws him in, makes room, accommodates him entirely, even as the unaccustomed stretch fires her nerve fibers. He pulls out almost all the way, then slides back in, stretching her even further. The feeling is exquisite, a bright tingling burn like an electric shock, and when Draco gets his thumb on her clit, she’s almost overwhelmed. Nothing in her experience has ever felt like this, nothing has come close. Her body begins to tense, tightening around him, and he pushes even deeper, forcing the stretch every time. "Fuck me harder, Draco," she murmurs.
