Multiple orgasms from fast fucking

I was sitting in my office, horny as hell, when in walked Sienna Day. A fit, blonde, beautiful woman, Sienna was having some back pain. Occam's Razor suggested it was her massive G-cup big tits causing strain on her back muscles, so I had her lie down for a massage. As I rubbed her lower back, I saw up her dress: she wasn't wearing any panties, and her tight pussy made me instantly hard! I had her stick her ass out to do some stretching, and when she got far back enough, I slipped my cock right inside her. She was a little surprised, but I told her a nice fuck would straighten her right out. After making her cum multiple times, I finished all over her pretty face. Her back might've still been sore, but with enough sessions, I'm sure she'll forget all about it!
