Michelle and a team of other nurses have a complicated table of ovulation times, so who I have sex with is carefully regulated. Also, I am not allowed... to have any type of ejaculation that won't result in an impregnation. My sperm is too precious to be wasted, of course. And I also am pretty tightly curtailed in what I do in general. I don't want to get hurt or kidnapped, so I am only allowed on and around the grounds of the hospital, always escorted by two bigger women.As far as my impregnation. I saw her red colour pantie. That made me horny. I never saw any girl like that before.My sister was squeezing her boobs and then my evil side took over me.I thought I can go now and hug my sister and squeeze her boobs and fuck her. But I also had a small fear in me. So I stayed under the bed itself and continued watching what she was up to.Then she removed her pantie also. Now she didn’t have any cloth on her body and was standing nude. Then she went inside the bathroom to take a shower. I. She felt the cold tip of the oil can force it's way past her rear and deposit it's cold load inside her. It was quickly replaced by a longer flexible tube. It didn't feel that bad, sort of a little unconformable but it was skinny. There was some sort of bar at the end that ran up and down her crack, she guessed it was to stop it going too far in. She was just starting to feel comfortable with it when she heard the bike pump go. She wasn't sure she felt anything at first but with the second pump. And when he is home, he is usually too tired. About every other Saturday he gets rested enough to make love."Kathy and I consider any week we don't fuck at least 3 times to be a slow week, and we hadn't had very many slow weeks in 25 years. I didn't know why Kathy was telling me this, but I was definitely interested enough that I didn't question. I just made some sounds to let her know she had my complete attention, and she continued."I couldn't believe it either, and said as much. Jean swore.
