He can't bring himself to stop her, even if for safety's sake he probably should. His eyes shut tightly as he feels her wet slit rubbing along his length, and thoughtlessly his hand reaches for the tip of his erection, pressing it against her and rubbing it over her clit, replacing the touch of his fingertips.

The sensation is more than he could have ever dreamt or imagined, making his heart race a little faster, forcing him to actually focus on how fast it is going, and if it's more than he can handle. And yet, he doesn't pull away, instead moving his hips slowly so the head of his cock rubs insistently against the sensitive knot of nerves, the rest of his length pressing up against her slit in the process.
