I ended up masterbating while writing down the story, letting cum spurt all over my keyboard.
During spring break my older brother of eighteen invites his friend over. His friend was good looking, brown hair, blue eyes and nice body. I would pass by my brothers room to get a glimpse of something good. I would end up masterbating imagining him naked.
Two days later we all decided to go swimming at our swimming pool, the thought of seeing him without a shirt made me hard as a rock. Finally he came over and changed, he came out and he was wearing his swimming shorts, he looked great. We were all getting ready outside putting sun block on and he sat down behind me. I quickly turned and spotted his massive bulge. My cock went hard causing a huge tent in my pants. His bulge outlined his penis. I tried not to stare but it was inpossible.
After he got up I went back, got a grip of my dick and started jacking off. I quickly let cum out ropes after ropes. Later that day after we had swam I stayed in my room while my brother and his friend were watching a movie, he had decided to sleep over. I was on the internet up to eleven and I assumed they were asleep when my door opened. I quickly closed the porn website I was on.
It was my brothers friend with just boxers and a white t shirt on. 'You don't mind do you?' he asked me, 'of course not,' I said. He sat on my bed and said 'I noticed you looking at my bulge.' I quickly told him I wasn't, he said 'don't worry, I do the same thing, I like masterbating over stuff like that too.' I felt cum pressure up my penis ready to jack off. I got up and locked the door.
'So do you want to masterbate?' 'of course, I have never masterbated with someone else.' He dropped his boxers and I was super horny. His testicles were huge, his penis was long and thick surrounded by brown pubic hair. I had never see a dick so huge, no wonder his penis was so noticeable along his shorts. He got both hands and stroked up and down. I was also rubbing my penis with my right hand as I looked at his motion. His eyes were closed as he breathed heavier. The tip of his penis was red, his legs started jerking as he got to orgasm. A long thin rope squirted out along with more oozing out of his shaft. His face was red as he tapped the tip of his penis and more cum came racing out.
I blew the biggest load too, I felt sooooo great. We each observed our cocks and got dressed. Everytime he sleeps over now we see each other for our masterbation session.
