I was a very stupid 18yr old, I put myself in a position unwittingly, the experience though solidified the very heteroflexible approach I have.
I was 18 and had just landed in Sydney after Infantry basic training at Singleton, I was alone living on the army barracks, it was 1995 back then porn really only came from adult stores there was little to no internet porn that's if you even had a 486 PC and a dial up connection, It was a Friday night and I was board and horny so I had a long shower stroking my cock and fingering my ass then headed into the city to get a couple of DVD's I could watch in my room and wank to over the weekend.
The store I ended up at had a "theatre" in it, the guy at the counter (John on the name tag) said I should go into the theatre and he would play one of the DVD's I'd picked so I could make sure I liked it, the whole porn transaction made me super nervous and I just went with whatever he said, he was a big confident guy his energy was pretty intense, it was the first time I'd ever walked into an adult shop and in reality I was way out of my depth with no idea, I was fighting embarrassment talking to someone with all the sex shop items surrounding me not to mention that he was looking at porn movies and advising me that he would be playing one in public which he knew that I was going to be wanking over later, I was losing the battle in my mind.
I didn't have the confidence to control my situation and I think he knew it, He told me to go in the room and he'd put one on, I went into the room as directed, it was dimly lit from just the large projector, there were two guys in the back row talking to each other and another three guys on their own sitting randomly in seats in the room, I sat as far away as I could from all of them so went to the front row, the movie playing was a girl being gangbanged, It abruptly stopped and a voice on the speaker said "sorry guys just putting one on for my young friend to ensure he likes it". The "Buttman" movie I had picked appeared on the screen.
I sat there watching the porn for about 5 minutes, one of the guys from the back row came and sat right next to me, I remember he had a black T-shirt on, he had scruffy black hair but that's about it, I saw him pull his cock out of his pants from the corner of my eye, he leaned over and told me something like, "pull your cock out, it's alright to play with it here", I did what he said but I felt really nervous and couldn't get hard, he reached over and took my hand and put it on his cock, I immediately knew to stroke him, his cock was long but skinny, I remember this stupid detail vividly it felt really skinny compared to the usual thickness of me holding mine, his cock was longer than mine but it felt small to me as I stroked on it for him.
He took mine in his hand and started to play with it, I got hard in his hand pretty quickly, what he was doing was feeling good, pretty soon after I was rock hard in his hand he got on the floor between my legs and pulled my shorts and underwear off and started sucking me right there in public in front of these other guys, they couldn't physically see him from behind us so I was hoping they didn't notice him move from the seat to the floor, it felt good and I could not bring myself to ask him to stop, A fight flight response was pumping adrenaline through my body as he took my cock balls deep in his mouth over and over.
I felt a hand on my shoulder and turned my head the other guy from the back row was standing behind my chair he had one hand at his lips giving me a shoosh gesture and he was pushing his rigid cock towards my face, he moved his finger from his mouth and quite forcefully just said "suck it" I opened my mouth and he pushed it into me, I honestly thought these men would forcefully do this if I didn't just go along with it, it was also evident that everyone else in the room would be seeing me suck this guy's cock at this point.
After a while of sucking cock and being sucked the guy between my legs grabbed my waist and pulled me forward awkwardly on top of him until I was on my hands and knees he'd gone onto his back and was under me still with my cock in his mouth, the other guy had stepped over the seats, he stripped off and went to his knees in front of me and rubbed his wet cock on my face telling me to "get back on it, suck it slut", I did as I was told. I spread my legs wide so my cock was at the right height to fuck my new friends mouth while he controlled my movements by pushing or pulling me by his hand firmly wrapped around my balls.
I felt something funny at my butt and turned to look back the guy (John the only name I got that night) behind the store counter was rubbing lube and licking around my butt hole, the guy I was sucking just told me to enjoy it, he grabbed my head in his hands and turned me back to face his cock and pushed himself in and out of my mouth, he kept telling the others I was all sorts of things, a good boy, a cocksucker, a slut, a cumdump and all sorts of other names, he announced that "We are all going to take turns fucking your holes until your full of cum you little slut and you're going to love every bit of it" with a gentle face slap to punctuate the remark, he really didn't shut up as he used me, he kept trash talking me and degrading me as he fucked my mouth, he wasn't that rough with me thankfully just a light slap with his hand or he would pull out and cock slap my face every now and then, I guess talking just got him off.
