When I went to an image club where sex is prohibited, I ran into an acquaintance from high school, a senior at my part-time job, my friend's wife, and a classmate from college. The play started in an awkward atmosphere. During the intercrural sex, I shifted my penis 3cm and secretly inserted it! I thought she would refuse, but she secretly said, "You're the only one for me." I had sex with her. I remembered those days and got excited, so I tried to cum outside her vagina, but she said it was okay to cum inside, and I came inside her.
