When JMac plunges his dick into Jenni Noble as they do the piledriver position (the girl's upper back on the floor, hips and legs in the air), you can see her legs tremble. I was very impressed with Jenni and her extremely enthusiastic, energetic, very natural sexual moves in this scene. The pros who make hundreds of videos have nothing on Jenni. Maybe because they've done so many hardcore scenes, their fucking looks mechanical. Jenni was not a porn star when she made this. She's a regular girl who works at a regular job, and I had the impression that getting into nude modeling and porn was a fun activity for her. I don't know if she had ever had sex with a super-stud like JMac before she came to SCORE. About being photographed fucking JMac, Jenni said in an interview with Dave, "It's exhilarating. It's like this huge rush. There's a lot of adrenaline going through my body. There's a lot of nerves, obviously, but I'm also really excited because this is the opportunity of a lifetime. This is awesome.
