Yes.

"I know i can. Just give me a chance" Tim begs.

"Wrong answer. I can feel a little sympathy for the whiteboys that know they are pathetic and accept it. But you, the whiteboys that still think theyre real men, im done with you." Jenna says, as she clenches the muscles in her ass, creating a vice like grip on his dick. She begins bouncinging up and down, and and now instead of stroking his dick, her ass cheeks feel like they are about to pull it out of its socket with every up stroke. She now moves her her ass left to right. She still nearly pulls his dick off with every thrust, but the side to side jiggles also cause his hard dick to bend in the middle, almost like it could snap.

Tim is now more turned on than hes ever been, and yet more vulnerable than hes ever felt. He knows he isnt going to last the full 5 minutes. He thinks over his options. If he cums, theres about a 25% chance he may survive, but even if he does he feels like Jenna may actual break his dick with this new torture/pleasure shes applying. Or he can beg her to stop, and most likely be laughed out of the Alpha Delta frat, and lose his social standing.
