We are three childhood friends who have been friends since elementary school. I confessed to one of them, Kei-kun, and I was dating, but I honestly didn't know how comfortable sex was because I had never dated anyone else. Of course, I didn't know anything other than Kei-kun. But,,, I found out that my penis, which reaches the back of the navel, spreads loosely, and every time my uterus is hit with that punch, I'm going crazy with climax.
