Me and my bro have been masturbating together for years.
The first time I masturbated in front of someone was when I was 18. My brother was 16 at the time and he walked in on me in the shower just as my cock was about to explode. He was amazed but I could also see he was fascinated with what he saw. 'Wow that looked great, how cum I don't shoot as much as that when I cum' He also explained that he's usually over very quick. 'Practice and taking your time and exploring your body' I offered to show him what fun he could have with the pleasure of masturbation if he was willing to watch. He agreed without hesitation.
Later that night when all my family had gone out I went into his bedroom my hard cock throbbing and waiting for some stimulation. 'You can watch me now if you like'? He was already in his boxers and he was hard as soon as he saw my hardon. 'I like to use lube' I unscrewed the cap off my masturbation cream I had purchased earlier in the day. I stood in front of him as I applied the lube to my cock and slowly stroked myself moving up and down the shaft of my hardon and around my cock head which was now purple and the pleasure shot through my body.
Grabbing my balls with one hand as I stroked around my helmet and squeezing my balls the fantastic pleasure pulsed through my body as my knees began to buckle. I could see the fascination on my brothers face, he was wanking too now and he was not too far away from shooting his load. We both stood next to each other as my bro shot his load onto the floor in front of him. I was still going stroking and concentrating on my now very stimulated purple head. The pleasure took over and my cock exploded with wads of cum all over the floor and onto his bed.
My brother was amazed at my pleasure and I vowed to teach him how to orgasm with as much pleasure as I did. Even now me and my bro get together reguarly and masturbate with each other, usually watching porn and we show each other techniques. We will probably masturbate together until we die!
