My step-brother, Tom, was 16 and had never had sex with a girl. I was 21 and had fucked a couple of guys in high school and college, and enjoyed the experience. A couple of times I had gone by Tom’s room and seen him jerking off while reading a Penthouse magazine. The third time I saw this, I went in and asked him why he was wasting his manhood on his hand when the real thing was available. He asked me what I meant, and I told him I’d be willing to let him experience his first time with me. He was surprised, and thought out loud that maybe it wasn’t right, and that my Dad wouldn’t approve, but when I told him what a great body he had, and how I really wanted him, and we really weren’t related to each other, he said O.K. without much more hesitation.

He was already in his jockey shorts, and so I took off my clothes and climbed in bed with him. He had a very nice sized penis, about 7″ long and it was standing at attention. I began by giving him fellatio, which I had also given before, and he quickly came in my mouth, but he maintained his erection, and I then lowered myself onto his manhood and rode him for awhile until he told me he was going to cum again, and asked me if it was O.K. I assured him that it was, since I was on the pill, and he then erupted like a volcano inside me, injecting me with the rest of his love juice. I told him how great he was, and kept him inside me for awhile before rolling over next to him.

We rested awhile and then he got hard again, and I let him take me from behind, doggie style, and he fondled my breasts at the same time. For a teenager doing it for the first time, he felt simply terrific.

We don’t do it often, but since that first afternoon, whenever he gets horny, he asks me if we can do it again, and we have terrific sex. He’s learned a lot since that first experience, and has thanked me for teaching him everything he knows. He now has a girlfriend — a senior at his high school –and I think he is fucking her, too.
