MWM, only gay night of sex, I still can't stop thinking about it

I was 19 and I had sex with 4 women by that time. I knew what I was doing and in for when I agreed to go with Alan to his apartment. I knew I was going to get fucked and have gay sex for the first time. I figured I'd have to suck his cock too. Alan was incredible, at 45 he had a body any teen boy would kill for. We were in the gym, had been talking through our workouts. We hit the sauna, naked together I saw his cock soft. Even soft it was 6 inches long and as thick and round as a half dollar. I was facinated and he noticed. Mine is only 6 inches hard and about an inch and a quarter thick. "You like?" he asked me sweat pouring out of both our bodies and it only made him sexier for some reason. I replied "You could hurt a woman with that thing". He told me he'd had women but for him it was guys that got him hard. "Like you" he said as he grabbed his growing cock getting it to full hardness. All I could do was stare at it. "Come on, let's get showered we'll go to my place" he said. We showered together, no one else around, I reached over with soapy hands and felt his cock get hard. He moved up behind me, placing his stiff, standing straight up cock between my ass cheeks. He started moving like he would be fucking me, reaching around he got me hard with his hand. Then we heard someone in the locker room so we broke, and turned our erect cocks to the wall.

Packing up he asked if I wanted to go with him. I did. He asked if I'd ever done anything like this before, and I had not. I'm a top, you would have to be the bottom. I knew what he meant and I told him it was OK, but only if he would take it slow the first time. In 20 minutes I had his cum in my mouth, his hard cock pulling out. I looked at him and swallowed. "Sorry, I'm a heavy cummer, probably should have warned you about that" he said. I swallowed again, "Did you get it all?" I told him I did. "Was that your first too?" he asked and I told him it was. He was surprised that I had never even sucked off a guy, and that he was to be my first totally. I told him about women I'd been with, he was getting hard again. I was jacking myself, but he stopped me. "I want you to do that when I'm inside you, when I'm fucking you". I sucked him hard again, and he had already lubed my ass generously, and put some on his cock. "What position should I be in?" I asked. "What do you want?" he answered. I wanted missionary and he told me my first time might be easier with me on top, or him behind me and us on our sides. On our sides, him behind me his cock made it all the way in after about 5 minutes of slow deliberate pushing. He fucked me for about 10 minutes that way, he said he could last a good long time since I blew him already. "Do you cum that much the second time too?" I asked him. He said he did, only about the third or fourth time did the amount go down. I pulled him out of me, and got on top of him. I eased my hole down onto his cock, resting on his lower belly the whole thing, not about 9 inches was inside me. I started rocking back and forth. Then when he pulled me down and started sucking on my nipples I went wild. I was fucking myself on his cock, fucking him like a slut bitch would do. He grabbed me, and we rolled over and he was on top of me, my legs around his ass pumping me like I did my girlfriends. He was telling me how good I made him feel, how tight I was. In another 15 minutes of what was now total bliss, he tensed up pushed in what felt like 12 inches into me with his 9 incher and I felt the hot jets shooting out of him.

He leaned down, sucked on my nipples, his softening cock still inside me. I just moaned. He looked down at me and said "Well, you really did enjoy it" I looked down and I had shot cum all over my belly and pubic hair. With that he slowly pulled out of me. It was then that I felt it. I didn't feel right, something was wrong, for the first time my butthole felt empty, and I wanted it filled again. I stayed with Alan for three days and nights. He treated me like a girlfriend, kissing me, feeling me, even in public. He'd take me out to dinner, movies, I even jacked him off in a movie theater, leaning over at the end to take all that cum in my mouth.
I got fucked 10 times, sucked him off 3 times. Of the 10 times getting fucked I shot my load 6 of those times.

When away for a few days, I took a slutty girlfriend out for drinks and dinner, then back to my place. Fucking her was good, it was a nice warm pussy hole to cum in, but I can't stop thinking about Alan and the feeling of his cock filling my boipussy, his cum leaking out of me and into my underwear as we'd walk in the park, or in my swimming suit at the pool. It's been a long time, I'm married have three kids, and I still can feel it, Alans cock moving in and out of me. I want it so bad.
