My sister in law has always been the prude of the family. She has always accused me of leading her sister astray. I never viewed her in a sexual way until recently. She always dressed very conservatively and was constantly on my case for obsessing about sex.
My wife, Jill, is on the other hand, a very sexual woman. That is another story, that I will tell another time.
Jan, my SIL and her husband were visiting us and staying in the guest room. The previous night had been pretty boring, filled with meaningless chit chat and we all turned in early. The next morning, I got up very early to get ready for work. I sleep in the nude and, as usual, walk from our room to the bathroom to shower and stuff. This morning was no different. I left our room and, still groggy, headed for the shower. I had a huge morning woody, you know, the kind that hurt because it is so erect.
I paid no attention to anything else as I walked. Just then the bathroom door opened and out stepped Jan, my Sil. We both just stood there frozen for what must have been 10 seconds.
She then broke the silence and said "Oooh, you are a big boy, aren't you?" She smiled and left to her room. I said something like "I'm sorry, I didn't know anyone was up. "
I then showered and left for work. When I got home I asked Jill if Jan had said anything to her about it. She smiled and said "Yeah, she told about it. "
Jan and her husband had left that morning, but, right after supper she called. I answered the phone and she said "I'm sorry I won't be there tomorrow morning." She then asked to speak to Jill, but, said as Jill picked up the other phone, "Bye bye sweety, I may not be able to control myself next time. " Then I listened in the background as they talked. All I could hear was some whispering and a lot of giggling. These kind of calls went on for two weeks between them.
I was now obsessing about her. This was so out of characters for her. I have to admit, I now wanted her very badly. Every time she called, she would talk very sexy to me.
