It had been a couple months since my sister in-law Carolyn's visit and life was pretty much business as usual. My wife told me her sister was planning another visit for the upcoming weekend because she got a smoking deal on a plane ticket. Carolyn had told my wife she had so much fun during her last visit that she wanted to come back and spend some more time with us. My wife, my son, and I picked Carolyn up at the airport late Friday afternoon and we all went out to a nice dinner. After a good meal and a couple drinks we headed home to put my son to bed. The three of us stayed up had a couple more drinks while we caught up on things.
After a while my wife was feeling drowsy from the alcohol and she went off to bed. Carolyn said she felt a little tired too and decided to read in bed for a bit and turn in. After Carolyn went off to the guest room I got on-line and surfed the Internet for a bit. After a while I logged off and decided to watch some TV before going to bed.
I turned the TV on and went to empty my bladder before settling in. As I was heading back to the living room I heard Carolyn call out to me from the guest room, which is right across the hall from the bathroom. I went to see what she wanted and found Carolyn sitting up in bed, wearing the same robe as last time, with a book in her lap. She said she had gotten a second wind and didn't feel that tired anymore. Carolyn asked me to come in and talk with her a while so I went and turned the TV off and returned to visit with my sister in-law.
When I returned to the guest room Carolyn patted the spot on the bed next to her and told me to have a seat. I sat down and asked her what was up. She said she really enjoyed her last visit, especially our evening together. She told me when she went to bed that night she had a little trouble getting to sleep. Carolyn said she is usually pretty self-conscious and was just lying there staring at the ceiling in disbelief that she had actually masturbated in front of me. In spite of her embarrassment she said she was still really turned on and had masturbated a second time before going to sleep. Carolyn said she could tell I had enjoyed what was going on too because she could feel my hard-on pushing against her back through the pillow.
I blushed and sheepishly told her how sexy she had looked in her lingerie that night and was sporting a woody pretty much from the start. With Carolyn talking about that evening, and visions of it running through it running through my head, I had a hard-on straining against my shorts as we spoke. Luckily my t-shirt was covering it. Carolyn told me she had used my idea with her husband when she got home and it worked like a charm. She just enjoyed great lovemaking sessions and didn't think about getting pregnant once during them.
