We did the same thing to each other whenever we showered together. The next week when our parents were out, my brother asked me if he could try something on me. Not sure whether it involved sex, I agreed. He took me to his room and unbuttoned and removed my shirt, I then knew it did involve sex and my cock started to get hard. He then pulled my pants and underpants off. I was naked with my cock standing straight out. My brother than undressed and I saw he also had a full on bone. He asked me to lie on the bed on my back. He brought out a small plastic container of jam, which he proceeded to empty onto my hard cock. Then to my further surprise he took my cock in his mouth and started to suck my cock with relish. I was in ecstasy having never had a blow job before. It was not long before I was cumming and I felt the spunk spurting out of the end of my cock, into my brother's mouth. He swallowed it all and kept sucking till I was finished. It was fantastic, even better than when we jerked each other off. He then asked me to kneel at the end of his bed and put my arms on his bed. He had a jar of Vaseline. He pulled his foreskin right back and rubbed some Vaseline onto his cherry. He then got behind m~ and slowly pushed his cock into my bum. Once his cock was fully lubricated he started thrusting it in and out. It was not long before he came. He also said his orgasm was better than me wanking him. One time while we in the shower and my brother was masturbating me, we must have left the door unlocked and my dad walked in just as I was just getting an orgasm. We were so shocked, that brother didn't even stop wanking me. He stood watching us, mostly keeping his eyes on my cock, and watched me shooting my load, smiling the whole time. After I had finished ejaculating, he walked out and closed the door. He never mentioned tl1is episode to either us again. We continued to have sex, wanking sessions sucking sessions and bum sex together, right up till the time I went off to college. Those were great times.
