This happened two days ago. My son was watching a movie on the living room couch and I sat next to him to relax. I put my feet on the coffee table and was dozing off than watching the movie. I wanted to take a nap so I laid down and put my feet on my son’s lap and put a blanket over myself. After a while, my son started rubbing my feet, I thought it felt nice so I let him continue. A little while later he started rubbing my legs, it still felt good so I didn’t really care. I was dozing off and sleepy, but I was still awake, I started watching the movie and a sex scene came on. At first, I couldn’t care less, but as soon as the scene started my son started to go higher to my thigh area. Shortly after, he told me to sit up because his hands were getting tired, I said sure and sat normally and browsed my phone. He kept touching my thighs, and I ignored it mostly until he asked if he could hold my hand real quick, I thought he was going to massage my hands so I said sure, when he held my hand he put it on his crotch and I could feel his erection.
