Last Saturday night I was drinking with my housemate, Lauren. We'd both had quite a bit and somehow we got talking about things that turn us on. I mentioned that I've had a fantasy about being blackmailed into sexual situations. Lauren said she'd be turned on by exhibiting that kind of control over me and started trying to convince me to let her actually go through with it.
We'd had enough to drink, that it wasn't too hard for her to convince me to let her take a video of me masturbating to use against me. I was wearing panties and a tee-shirt at the time, so she recorded as I stripped. I lay back on the couch with my legs spread, and rubbed my pussy. Between the audience, and the thought of being blackmailed, it didn't take long for me to reach orgasm. She made me stay naked for the rest of the evening, and we went back to drinking and hanging out.
