My first sex was m2m, after only women

We grew up together. We stayed at each others houses. He and I were always staying over at each others house. We were the same age, I was brown haired, he was blonde. He didn't have much body hair, nor did I. I was much more interested in his mom and his sister who was a year younger. We used to set up peep holes and could watch both of them in the bathroom. I guess it was me doing most of the watching. One night he and I in our undies under the covers in a double bed he took off the cover, and took off his underwear. His smooth, firm butt in the light coming through the window at night. He produced a jar of vaseline, and rubbed it on his ass sticking a finger in it. "Put some more in" he said as he handed the jar to me. I first rubbed his ass cheeks, he liked that. I had a super hard cock. I'd not fucked anyone yet and just wanted to fuck. I always thought it would be a girl with me imagining his moms black haired bushy pussy or his sisters not too thick brown bush. Now I pushed more vaseline into his ass. With my finger in his ass all the way he was slightly moaning and wiggling his ass around.

I put some on the head of my pretty thick cock. He was lying on his belly his legs spread, his hands pulling apart his cheeks with his little pucker, untouched till now showing and ready for me. It was the first hole I was going to fuck. His and my first fuck. I never imagined it. I started slow, pushing the head in and holding it. "Keep going, put it in, I need it in me" he was saying I slowly pushed it all in up until my pubes were on his ass. He started bucking back and forth on my cock. "Come on do it" he said. So I started moving it around, "No, not like that in and out" he whispered. I started fucking now, pulling out and then pushing back into his tight, tight asshole. He was moaning, "Yeah, oh yeah, just do that, as much as you want, anytime you want" he told me between his moans. I stopped, he asked why. "If I keep going I'm going to shoot my sperm in you" I told him. "DO IT" he was demanding. I speeded up and within two minutes I was rammed into him farther than I thought possible shooting my cum deep inside him. I stopped, he was breathing hot and heavy, I rolled off him. We turned and facing each other, he reached over and got some tissues and started wiping up his cum. He came while I fucked him. He got up went to the toilet and came back. About 6am I woke him up and fucked him again. Later that day I fucked him with his mom and sister out of the house for a few hours. That time just his pants down to his ankles, he was bending over the kitchen table while I dumped another load of my sperm up his ass.

He and I stayed fucking quite a lot. I didn't consider it gay for some reason, he did. His sister became my first piece of pussy. Turned out she and their mom knew I'd been fucking him. The sisters ass was tighter and her pussy was virgin the same with her mouth. I never had another guy after him, it went on for about 4 years. I'm married to a woman, we have 3 kids but I never forget that my first fuck was another guy and I liked it enough to go on, even while I was fucking his sister.
