My Sons Bed

I'm a 48 year old woman recently divorced. I have 2 boys from 2 previous relationships. For a long while it was just my boys and I until I met my ex husband. The boys loved him which made me feel like I had met the right man. I told him that I wanted for us to be completely honest and tell each other about our past. I started to tell him everything and let him know that I was afraid to lose him after I told him some really personal things that I had done and had happen to me. I told him that my stepbrother had sex with me when I was 9 and he was 15. I told him every detail and that I have also had sex with 2 of my cousins. I explained to him that sex was just sex to me and that I could sleep with anyone and not have feelings for them. What he doesn't know is that when my youngest son was leaving for basic training I wanted to spend as much time as I could with him before he left so I started sleeping in my son's room on his bed. I've always slept in a long shirt and my panties and I've always been around my boys that way. My son and I were laying in bed and I rolled onto my side pulling his arm around me telling him that I wanted him to hold me. He held me close rubbing my stomach and I could feel his breath on my neck. His hand kept moving lower and lower as he rubbed my stomach. He ran his hand across the front of my panties and then ran up and down my leg. I got carried away when he kissed my neck telling him to bite me a little. His hand was rubbing my ass and slid his finger under my thong going up and down. Automatically I reached down grabbing his hand telling him to bite me harder and rubbed myself with his hand.
