There was once this acquaintance that I would have casual sex with. We did not know each other well outside of fucking. We would fuck bare, and when she was not ovulating she would let me finish inside. When I was close, I would ask if it was OK to cum inside. She would never say “no.” It was safe she would say “yes.” If it was not, she would say “you can cum inside but we might make a baby.” So hot. But it was anticlimactic because I would have to pull out. So eventually I requested that when it was not safe, she should say “no” and save the baby talk for when I could cum inside her. She obliged and I found it so sexy. It was fun “making babies” with her. I nutted inside her so hard. She was great.
