My friend's parents were going out of town, to one of his sister's basketball games, for the weekend. He asked me if I wanted to stay with him at his house while they were gone. Night time rolled around and we decided to sleep in the living room and watch porn. I was horny before we even started. I was lying on one couch and he was on the other which was positioned 90 degrees to mine. I knew that he masturbated and was hopng to watch him so after a while I pretended to fall asleep. He waited a few minutes then said my name. I didn't answer. He then stood up and walked out into the kitchen. I could see his erection poking out his boxers as he walked back with a piece of paper towel.
My cock was leaking precum with anticipation of what I knew was about to happen. He said my name again and again I didn't respond. Through half opened eyes I watched as he slid his boxers down to his ankles. His hard cock illuminated by the light of the tv that his eyes were glued to. His cock was probably 6' long and pointier than mine and considerably thinner. He was circumsized, like me, and had a full head of hair above his unit. His balls seemed tight to his body indicating he wasn't going to be long before he lost his load. I watched as he grabbed his cock and stroked up and down, keeping in rhythm with the lesbians on the tv.
A minute later the girls on tv were climaxing. He sped up his stroking and lifted his ass off the couch and shot his load onto his stomach. My cock was aching to do the same as I gently rubbed precum on the underside of my cock. He cleaned up with the paper towel and pulled up his boxers. He was asleep in minutes. I got up, grabbed the papertowel, and went into his younger sister's room. I turned the light on and looked at the cum filled paper towel and touched it with my finger. It turned me on. I then wrapped the wet paper towel around my rock hard penis and began to stroke it. It felt so fucking good. I was on the verge of cumming when I saw a pair of his sisters panties on the floor. I picked them up and looked in the crotch to see if they were dirty or clean. My lucky day. There was white crust and a few brown pubes in the crotch.
I stroked my cock as I lay on her bed, with her panties in my mouth and her brothers cum on my cock and in my belly. I started jerking fast until I shot my cum all over myself and her pillow. It was a strong orgasm. I then cleaned up with the same paper towel, put the panties back on the floor and went back out to the couch. I tossed the paper towel next to my friends couch where he left it and drifted off to sleep.
