My cousin waves bi

I was a senior in High school and school was out for spring break. My cousin Mark came to visit our grandparents. Mark was about 35 yrs old and I though he was kinda cool he played music and like to party. We went out drinking and around mid night I mentioned I wanted a stop sign he wanted some road signs too. We had a good buzz going he said let's make it a little dangerous by stealing road signs butt naked I said ok. We drive outside of town at a road side park where we get naked. Mark put his clothes in the trunk and I didn't know he put my clothes in the trunk too. It was exciting riding naked. We got some signs then I said let's get one from inside the city limits. He suggested we park a couple of blocks away from downtown and sneak downtown and get a stop sign in the buff. I had drank just enough to do it. We agreed to park at our grandparents three blocks from downtown. We made it and got the sign and was almost home and we almost was spotted and for some reason it excited me for real I got a hard-on. We got to the house and Mark noticed my hard cock and as he was commenting on my cock his dick got hard too. Mark reached out grabbed my cock and ball and I just stood there letting him cup my cock and balls. He ask me if I liked this and I answered it's ok. Mark went to his car and then told me he lost the key to the trunk and then I find out my clothes are in his trunk too. We quietly and naked went in the house to his room.He said we both could use the bed. I had a headache and laid down in the regular size bed. Mark had me lay on my belly and he massaged my back moving up to my neck and I could feel his hard cock press between my ass cheeks after a while he massaged from my neck to low back up and down my back and his cock slid up and down my ass. I didn't know when but I had pushed my butt up and out parting my legs a little and on his stroke up I pushed against his cock. He stopped and I turned over he turned out the light and crawled into bed. I dosed off only to be awaken by my cock being sucked. Mark gave me the most amazing blow job ever even eating my cum. I told him how good it was and he ask if he could do something else I said as good as that was he could do anything he wanted. He took my hand and wrapped it around his cock wanting my to jerk him off. I jerked his cock for a while when he ask if I wanted to suck on it not waiting on an answer he grabbed the back of my head guiding my mouth to his cock then told me to lick it and I did. Then he told me to put it in my mouth. I started taking more of his cock little at a time when he grabbed the back of my head forcing more cock down my throat the he pushed hard making me take all his cock holding me there a shot cum down my throat. He stayed for a week and by the end of it he had me sucking cock like a pro loving the taste of cum.
