Wasn't For Me

My parents divorced when I was 12. Soon after dad came out as gay and I guess started a mid life crisis. He became a party guy.
The upside of this was the lack of rules. When I visited him I was basically free to do as I pleased. I was too young to realize this was not a good thing. When I was 16 I wanted to live with dad full time just for that reason. Mom was pissed but she said OK to avoid conflict.
Dad treated me like a buddy and I got to do whatever I wanted. I quickly realized dad was even a bigger partier than I thought. A lot of different guys would come and go. He didn't do anything sexual in front of me but the walls were thin and I heard a lot!
Also the guys that were always around noticed the 16 yr old boy. I got hit on a lot. Dad thought it was funny.
One day dad wasn't home and a guy I had met several times stopped by. He came right out and told me he wanted to fuck me. I don't know exactly why but I led him to my room. After we stripped he made me lay down on the bed. He sucked my cock until I came in his mouth. After he looked up and asked me if I had ever sucked a cock. I said no. A minute later his cock was in my mouth. It took me awhile to get him off and I choked and gagged trying to swallow his cum. Most of it ended up dribbling out. We laid on the bed for awhile and he asked me a lot of questions. He got up and started to walk out but he told me to stay put. He went into dads room and came back with a bottle of lube. He stood beside the bed, poured lube on his cock and stroked it until he got hard. He grabbed me, rolled me over on my stomach and poured lube on my asshole. He fingered me for a minute then pushed his hard cock inside me. He fucked me hard. Yes it hurt but I took it. After he came inside me we cooled off, then dressed. When we came out of the bedroom I realized dad was now home. I figured he would be mad since I just had sex with one of his boyfriends. Instead he acted proud of me.
From that point on dad was more open with his sex life. He started leaving his bedroom door open and I saw him having sex several times. I found out dad was definitely a bottom.
Over the next couple of weeks the guy came back specifically to have sex with me a few times.
The night I decided this lifestyle wasn't for me things got way out of hand.
The guy I was having sex with stopped by with a surprise. He had two men with him. One I had seen before and the other was a stranger. He took me into the bedroom and the two other men stayed in the living room with dad. We played around for a little, mostly he wanted to give me a blow job. After I got off he took me by the hand and pulled me off the bed. He opened the door and tried to lead me out of the bedroom. I tried to grab my clothes but he insisted. He led me back into the living room. Immediately I was hit with the sight of my dad and the other two men naked. Dad was on all fours with a man fucking his asshole while the other had his cock in dads mouth. We sat on the couch and watch for awhile until my friend became too horny. I ended up on the floor getting my asshole fucked . The three men took turns on me and my dad for several hours.
A few days later I went back to moms .
