Pete was tired in this scene, you can tell he wasn't enjoying himself. Legend has it that his agent quadruple booked him this day. His agent was a cruel old Hollywood jew that used and abused Pete and took advantage of his talents. On this particular day Pete was booked for 2 DP's and 2 threesomes. Pete still managed to get his dick stiff and deliver an impressive money shot even though the scene was average. This was just a testament to Pete's talent and freak of nature sexual drive. When Pete collapses on the couch he is not acting, he was physically exhausted.
