My wife had headed off to the mall to do some shopping and I decided to use the time to jack off to some porn. My wife is nice, pretty, and likes to fuck, but only on her terms and when she wants to which is not nearly often enough for my desires. I had started buying porn, and watching porn movies to keep things under control. I did not really want to cheat on my wife and this seemed like the best way.

I really like the moves where I watched a woman masturbate and the ones where big cocked guys ended by ejaculating on the girl’s tits. My wife would never masturbate for me, and I always had a fantasy of ejaculating a big load on her tits, but again I never felt like the time was right to do it, or even ask her about it.

I loaded the CD I wanted to watch today. It was of a girl named Petra and she masturbated using her fingers and a big dildo. She had a big set of tits, with thick dark nipples that she liked to pull and rub while she fingered her clit. She had the most amazing loud screaming orgasms, and I always like to cum while she did, imagining my cum dripping off of her nipples. There were a couple of scenes where a big cocked guy fucked her hard for a while and then jacked his load on her big tits. I really liked to masturbate to that one as well.

Today I was watching Petra’s solo act, and I was pumping my hard cock slowly, waiting for Petra to climax so I could jack my load; I had just reached the part where she was pulling and twisting her erect nipples with her free hand, while her other hand was pumping a big vibrating dildo into her pussy. My eyes were locked on the TV, and the room was filled with the moans of lust of the lovely Petra. Suddenly I realized someone was at the doorway to my bedroom, some small movement caused me to turn my head and I realized that my wife was standing in the doorway.

I just about came out of my skin I jumped in surprise so quickly. My cock was shiny with the lube I had applied and as big and thick as it ever gets. I could see her eyes flick between my stiff boner, and the porn on the TV, her face was an unreadable mask of horror, surprise, I could not really tell. Petra was climaxing on the TV her loud moans of lust filling my bedroom, her big tits jiggling as her hips pumped in ecstasy against the vibrating dildo. I reached up and turned off the TV and the room suddenly went silent. It was just the two of us, staring at one another, each frozen. . .
