My husband is most of the time away from home so I end up spending most of my time at home with my son. I'm 41 and he's 19, on one of our Summer trips because the hotel was full, we had to sleep on the same bed, it was the only room available. That night when he thought I was already a sleep he started to rub his hard cock, from behind and between my legs. I felt his hands on my waist but I let him finish. The next morning I decided to show him I wanted it too...
