I guess my first bi thoughts started at 10when I tasted the cum I just shot through my gymshorts. Then at 13 would have blown my first guy but we were interrupted. I then thought if I was a girl I would suck and swallow every cock I could get in my mouth. Sometime After I fucked my first my first pussy, and came in it at 13. I began to wonder what it felt like for a girl to have her pussy stuffed and cummed in. By 22 sucked my first cock and wanted to be fucjed but loved sucking too much to give up sucking it to try to get fucked. I would always leave the door open as I sucked cock in my nylon black speedo at abs. Guys jerked off and shot on my ass as I sucked and I loved age 30 I was sucking cock in the steamroom of the gym naked. The other guy who was playing with his cock encouraging us to play stood behind me and fucked and bred my virginal ass as I sucked cock loved it and finally felt what a girl felt like. Still loved sucking too much to offer my ass all yge time, but always offered it up while sucking a cock. And occasionally just got fucked one suck time by this BBC who I begged to brew me as he happily did.

I came out as gay first and had my first bi experience when a guy I hooked up with regularly asked if I wanted to join him and a girl he had met. Hadn’t actually thought about it before, but agreed and got rock hard playing with her tits and then eating her out while he was fucking me. I ended up pounding her too and loved it. She was so hot: beautiful tits and a delicious smooth pussy. Ever since I’ve been as into girls as guys and love MMF fun with couples.

Mine was actually quite sudden when Peggy popped of my cock and sat on my face after fucking her the first time without a condom as hubby Matt wet down on my cock! (Circa 1995 via AOL chat rooms

Bi making me JERK UP into Peggy's PUSSY, it was also the first time I tasted my own cum IN HER PUSSY!

It was then that I realized Matt had been licking my cum off her tits and ass after playing together in the nude.

TOTALLY CHANGED ME in the twinkling of an eye!

I guess mine started when I was a teenager(shocker right?! XD) and I was younger and more flexible… one day I was having some of that post nut clarity where you’re like half monk and start thinking too much lol anyway everyone has fantasies, some you don’t quite want to share right away, and honestly I put myself in “their” shoes is the best way to put it. Idk about anyone else but when I was getting smacked by puberty I wanted my two friends at the time who were blonde and the other redhead to have a fun time with me (fmf) so for all I knew they wanted the same in reverse (mfm). Sounds kinda dumb out loud, but they were Great friends, so it was kept at that respectfully. I just wanted to prep for the day of being there for them if it ever came. So jerkin it didn’t do it one day and got this….idea… lmao. Found a chair, got relaxed, locked my arms behind my knees and found out I could comfortably fuck my own mouth XD. Needless to say I was not only ready but also a game changer lol.

Definitely as a young teen. With a cousin. He just started rubbing me one night when watching TV. It feels so wonderful. I told him, that was it for me, he Peale away my shorts. And sucked me dry, probably 14 at the time. Of course I couldn't resist sucking his. I didn't expect that cum load, more on my face. Our parents upstairs. We scrambled to clean up. And become regular cock sucking cousins.

Iwas in middle school and we had to take showers after gym class. I was mostly a voyeur and watched and got curious as some of the older bullies started harassing the wimps in the class. I guess that's when I started to actually start getting serious about starting to work out because part of me didn't want to be bullied but part of me did.
I saw one of the bullies make another kid get down and he forced his dick in his mouth while another held him down so he couldn't get up and when the first was done they switched places.
I went home that day and I was limber enough that I could put my legs over my head and I stuck all the head of my cock im my mouth just out of curiosity.
I didn't actually suck my first cock til my senior year of HS

Every year in school I had a particular boy I was infatuated by, and a girl who I was equally infatuated with. And that began in the first grade, until my senior year in highschool. If that didn't mean I'm bisexual, than I don't know what does. If I had to pick between the two sexes, I couldn't. One time I was asked the same question by a therapist, and couldn't choose. When she pressed the issue, I gave up and told her to pick for me. When she continued to ask, I explained it like this; " You know that 'B' in LBGTQ, that's me!

By third grade I was interested in girls, but would check out the guys in their gymsgorts. A couple of cute asses lots of bulging or at least outlines of cocks one occasionally peaked out the bottom leg opening. AlwYs checked for stains on other guys white gymshorts as my always had at least one cum stain on them. I didn't have a sister so panties weren't an option yet but I did check for a bit of panty showing from the pack waistline of a girl bending over . Guess I was just a purve

I guess when I was 17 and had just graduated from high school. It was my roommate and we were buzzed one night. He wanted to put porn on and asked if I was okay with it. I said yes. It was straight porn. He asked if it was ok if he whipped out his dick and stroked it. I said sure. He would once in a while reach over and rub my cock through my pants. I told him no once or twice. the third time, I pulled my pants down and said that he could suck my cock instead of rubbing my crotch. He went down very quickly and worked me over until I was cumming deep into his throat. After I came, as being too sensitive, I pulled out of his mouth. He stood up and took my hand and placed it on his cock. He said that the least that I could do was jerk him off to finish him. It was already rock hard so I stroked it for a few. He then took hos one hand and placed it on the back of my head while his other hand guided his cock into my mouth. I started sucking on his cock and fondling his ball sack. He came in my mouth within only a few minutes. I had never seriously thought about being with a guy, prior to that experience. We blew each other over several years. One of us would come back from being with our girlfriend and be horny as hell. Many nights I was woken up by him crawling into my bed naked and doing a reach around to wake me up. It always ended in oral.

I was 9yrs old with a school friend same age. We was playing in a old barn. I had to pee so I went to a corner. As I was done I seen him there looking at me. He asked if he could touch it? I don't think anything of it and said ok. He started playing with me and it felt good! But then it felt great because he was sucking me! It felt so good that I had to do the same to him to make him feel good! After that we sucked each other every day all day for months till he moved away! Didn't do anything else till I was 16 but that was fucking my girlfriend! Then after I got married at 19. My wife wanted to have a threesom with her ex at 28. When he came over she wanted to see him and me together. So we played a little and I sucked him till he cum in my mouth! First time I tasted cum. I liked it! But made it so he couldn't fuck her! I fucked her as she sucked him! Then made him eat her cum filled pussy! Then I wasn't with anyone till I was 35. I was to get with a couple. But she was sick. So he and I got together. We sucked each other and he wanted to fuck! I had never been fucked before or fucked another guy! But we did ,he fucked me a little! Then I fuck him a little. We went back and forth several times till we cum in each other's ass! Then at 55 the wife and I was not doing anything. So I'd go to GH or theater and had many guys suck me and I sucked many too. So now if I can't find a female or couples. I'll suck cock! I love cum in my mouth! Be it; male, female or couples! I just want cum in my mouth!😛👅💦🔥

I was having sex with my GF at the time, mid stroke she suddenly asks me if I think it would be hot to suck another man’s cock with her while we screwed. It wasn’t a turn on in the moment, but it planted a seed since she had brought another woman to bed before, and I kinda felt guilty. Anyhow, she was long gone when I finally tried men, sorry ladies, my D may be great for your orgasms, but I want man meat myself now!
