My kid brother, is very much a 'he man'. He never shows emotion and is never phased by anything.
Allan can be a jerk, but he is basically a nice guy, sometimes too nice, maybe. One evening I passed his room and I heard sobbing. Not just crying, full on sobbing. I peeked through the crack of the door and he was just sitting on his bed crying his heart out. I walked in and sat beside him and just hugged him until he was able to talk. I thought something dreadful had happened, and, I suppose, for him, it had. He told me of a girl at school who he had been going out with for about six months and that he had been feeling odd while they were kissing. On further examination, it turned out that he was really frightened of allowing any form of sexual contact and she was on the verge of dumping him. I told him that if she was going to dump him just because he wouldn't do anything sexual with her, then maybe she wasn't worth it in the first place. What girl would allow herself to be emotionally blackmailed by a boy like that?
Then he told me that he was worried about letting her touch him because he 'wasn't normal.' It turned out that apparently, my little brother, to put it briefly, not only comes a huge amount, but also has very powerful ejaculations, or so he thinks.
As we were talking I could see he was getting hard and I decided to teach him that maybe what he was like was just fine, so I put my hand on his cock. It felt really quite horny touching my own brother like that. Soon, I had it out and was jacking him gently. I asked him to tell me if he felt close. I must admit that I was really creaming myself as I did this. Soon, he said he was going to cum and then, well, I am not exactly over experienced myself, but holy shit can he cum. It went on for a long time and shot almost across the room. Then I had a brainwave and told him that he should let Alison do this to him and then to tell her that it was her that caused that massive reaction. She will love it and he will feel ok about it.
I went back to my room and tried to take my mind off what I had just done, but, of course, I couldnt. I had to finish myself, and the splash of his cum on my hand and lap helped just fine!
