Neighbor Made My Wife Cum

My single good-looking neighbor was over for coffee, and it started out as a simple discussion - we were debating whether women orgasm during r*pe. My wife said she thought there was no way a woman could cum involuntarily. She said she never cums unless she is into it. The neighbor said, "I'll bet you $100 I can make you cum against your will within 10 minutes. I would touch you but you'd keep your clothes on." I was a little uncomfortable but my wife said it's an easy $100 for a few minutes work.

When I agree the neighbor told her to lean back on the couch and spread her legs apart. He told me, "It's your job to watch the clock and tell us when the 10 minutes are up." He started by rubbing her tits. Her nipples were hard within a minute and he pointed this out, much to her embarrassment. Then he reached between her legs and started rubbing her pussy. He started talking really dirty, saying things like, "Your pussy's getting wet, isn't it? Admit it. You want a big hard cock in your hole, don't you? " I wanted to stop it, but it looked like my wife was getting into it, thrusting forward slightly and her breathing started to become labored. He went on teasing her about being a "nasty slut," taunted her about the wet spot between her legs, and told her that her pussy was getting ready to take "a stud with a big dick." At about the 8 minute mark she said, "Oh no. I'm cumming" and she started to jerk and moan. When she settled down, she kept apologizing to me and said she couldn't help it and was really embarrassed. Our neighbor looked smug - he said, "Keep your money. I enjoyed myself and looks like your wife had some fun too. Your embarrassment is payment enough, buddy!"
