This is about how things started. PreAneros. My wife and I found a prostate stimulating probe. Cheap. Looking back she was not interested in this but wanted me to have fun on my own.
It was small, black, and it vibrated. It was not enough to get me off but it was fun.
The next was a cheap knock off. We were involved in foreplay and mutual masturbation. She had an orgasm and fell asleep. After 10 minutes of feeling horny, I got waves of pleasure. They didn't stop for 20 minutes. I was breathing heavy, having contractions, giggling, and crying. She was asleep by this point.
This toy never "produced" again. It was impossible to clean and it was tossed out. I was hooked and went searching for something that would last. Aneros.
