About To Mess Up Big Time

I am seriously considering having sex with my biological son. To give you a quick background I married very young. Realized I was gay. We divorced and she was pissed. At the time we had an infant son. She refused to let me see the child and eventually i gave up. Moved to California.

Now to the present. A few months ago this 18 year old kid showed up on my doorstep. His name is Mark and he is my son. He doesn't get along with his mother because he is gay. Now she is double pissed. So I let him move into my spare room.

I quickly found out Mark is a party boy and hitting things pretty hard. I went through that phase myself. It wasn't long before Mark started getting me into some old behaviors. Rather than a father and son relationship, we became buddies. Thats where things went south.

It all started when Mark and I began sharing the same sex partner. Our partner was not too discrete and loved comparing notes between us. One evening the 3 of us were alone at my house and things went too far. There I was staring across at my son with our mutual boyfriend between us. I was pumping away in his asshole as Mark filled his mouth. That was just the beginning. Mark got me into attending all male swinger parties. We watched each other do some really freaky shit.

But last night... It was a night in and we were both just hanging around the house. I was sitting on the couch watching TV. Mark came out of the shower and I quickly realized he was naked as he sat down beside me. He made small talk and mentioned he was bored as he slowly stroked his cock. Mark stood up with a semi erection and announced he was going to bed. He also added the door would be open if I wanted to join him. I wanted to so bad but somehow I managed to stop myself. I quickly went into my room and locked the door. I nearly pulled my cock off to get some relief!

I don't think I will be able to say no again.
