I had been friends with Craig since we were teens in high school. Now we were both in our early twenties. I was supposed to stop over to Craig's mothers home in order to pick him up. I saw their cars in the driveway so I went to the front door and knocked. No one was answering so I tried the door. It was unlocked so I went inside.
I didn't see anyone immediately but I did hear voices coming down the hallway. I walked down to where the bedrooms were. I came to Craig's room and I peeked around the corner. I couldn't believe my eyes. There was Craig and his Mom in bed. They were busy fucking. My friend was on top of his mother. She had her legs wrapped around Craig's waist.
I think I had my mouth opened. I must have made a noise. Both of them turned and looked towards the doorway. I guess I was embarrassed being caught looking. I quickly turned and walked out of the house. I got into my car and drove away. There is a wooded area not far from my friend's house. I pulled my car into this area and I stopped the car.
I could feel my dick stirring in my pants. I replayed what I had seen back there. I unzipped my pants and pulled my cock out. I had to do something. I began to stroke my bone. In my mind I saw my friend's prick sliding in and out of his Mom's pussy. I could see how wet she was. I also remember hearing the both of them grunting and moaning from fucking one another.
I reached for a box of tissues I had in the back seat. My hand was moving up and down my hard rod. I just had to release the pressure. I felt that tingling and I let go. A gusher of cum shot out of the tip of my cock. I managed to catch it all in the tissues I had. I was panting as I finished stroking myself. I had no idea what I would say to my friend.
It ended up I didn't have to bring up the subject. The next day Craig drove up to my parent's house. We stepped outside and Craig spoke to me.
"Tom, you have to promise not to ever say a word about this," he urged me.
Craig confessed that since his Dad left them he had been screwing his Mom. They were full time lovers these days. Craig even said he wasn't interested in girls our age. His Mom had been fixed long ago. There was no worry about her getting pregnant. He also dropped a bomb on me. His mother brought up the idea that I could stop by for some fun.
