I strongly suspect I was not the first to use the thrusting sex-machine. My husband assembled it, charged both the remote and machine and left it on the bathroom sink. In the garbage can was a condom wrapper. So I think he had some anal sex with it. I asked him if he used it, and he didn't answer.
I'm not great with technology and asked him to show me how to use it. On the control pad was the charging port, on/off, thrusting control, heater, and vibration buttons. It was big and bulky, so I asked him to use it on me for the first time.
He positioned a rolled towel and gently pushed it in. I had already used a clit vibe for 20 mins and thought I was ready. It didn't go in smoothly. He had to angle the curved head and slowly push it in. I was very apprehensive. Nobody wants pain while having sex. The head was soft, but the shaft was very firm.
He started it on low and went through some cycles. I felt they were too much. He turned it off and handed me the remote. I used the low setting for quite a while until ready for more. After a while, I settled on the fast thrusting, then slow, then fast again. I also turn on the vibrations and heat. The combination of thrusting and strong vibrations was super! I came slightly after about 10 mins.
