My brother got so excited he almost unloaded in his pants
My brother is a year younger than me but he still acts like a much younger kid which gave my parents some concern as he was growing up. Still, he and I get on well together and he often slept in my bed, it was a double so space was never a problem.
On the very first morning of the summer holidays I woke at just before six which ticked me off a little. I turned to see Ben still sleeping with his face to me and he had kicked off the sheet so he was lay on his side wearing his boxers the same as me. He mumbled something I couldn't make out the he put his arm between his legs a started humping it with long slow thrusts and he was moaning something that was too sleepy sounding to make out.
Despite the fact that Ben was my brother I still had to watch him and I was looking between his leg at his boned organ that was now poking out of the front of his boxers. He giggled still sound a asleep and stopped humping turning over onto his back giving me a full view of his erection and it was a gorgeous looking dick with the veins well pronounced and the purple head pushing up. He smiled and I almost yelled out and his dick jerked as if it was alive and he moaned very low pushing his hips off the bed exposing more of his manhood including now his hairless balls that slipped free. He arched his back as he shot three decent ropes of cum on his stomach and chest. I was amazed he was still sleeping after that but it gave me the opportunity to carefully get his semen off with my hand and jerk off while looking at his deflating member that I desperately wanted to suck.
Maybe one day I did it that will be another story for another day.
