First time sucking a penis

Well, this story is real, it happened to me about four years ago when I was 20 years old and turning 21, I want to clarify that I hadn't had any contact with another man before, but I wanted to start, I fantasized almost every day about having a penis in my mouth, savoring it, filling it with my saliva and seeing how it would slide down my mouth, I didn't know how to start, I thought about going to that kind of disco, but I was afraid of getting carried away and things happening more than I planned, but for my luck I discovered the Grindr app, I was anxious but very scared, I posted on my status what I was looking for and after a few minutes many wrote me back, some polite ones and others sent me a picture of their already large member asking if I wanted to try it, I'm not lying that those made me hornier and made my member harden quickly and start to get wet with that liquid, so two days passed and they always offered to go to an accommodation, which didn't make me feel very comfortable, others offered to come to their homes but very late at night, until someone wrote me offering to suck it off in the porn cinema nearby and would pay for my entrance, I thought about it for a few minutes and told him yes, I took a shower, washed everything thinking that maybe things would get out of control, I got dressed in clothes I don't use often and a hat so they wouldn't recognize me, I left very nervous but with excitement, knowing it was wrong and not normal, which excited me even more, I arrived at the cinema door and wrote him to come out, he came out and recognized me quickly, the point is that he said let's go in already and I told him okay, it wasn't a big deal but also not bad, but that moment I don't know why I didn't care, I just wanted to suck a cock, paid for my ticket and we went in, everything was dark, they were starting another movie about high school girls, I turned towards the seats and saw there wasn't much people, maybe it was early, most of them were in the middle and one at the end of the row, none next to each other but most with their pants down. He could see his cocks already big, I stayed for a moment there watching, until the one who invited me grabbed my arm and pulled me to the last row to a corner and we sat down, started watching the movie, it was already in the scene where the schoolgirl takes out her cock and puts it in her mouth, didn't know how to start, I was nervous, thought about putting my arm on top and let things happen, but he did it first, put his hand near my crotch and started rubbing me, felt good and started getting warm, grabbed my hand and took it straight to his bulge, felt like it was already big, started rubbing him over the pants for a couple of minutes until he told me Get it out and eat it that turned me on even more, I lowered the zipper and found his hard member, it was 14 cm long, grabbed it by the base and started masturbating as he used to do with me, when I felt his other hand pushing me from behind towards his erect cock, didn't resist and went down until the tip hit my lips, he moved his hips trying to penetrate my lips, opened my mouth a bit and saliva dripped onto the tip, it was an exciting accident, hit my lips with his penis and opened my mouth, he almost pushed it in, seemed like he was going to suck my mouth and my saliva would run down his cock, making everything slippery and easy for him to enter, stopped and I knew it was my turn, grabbed him by the base and started sucking him like a popsicle, that was the only thing I knew I had to do, while leaning forward sucking his cock, he put his other hand in my backside, looking for another hole, at that moment I felt very turned on and loosened what I was wearing, rubbing all over there, not a disaster, until he reached the point and started rubbing me in circles with some pressure to see if I could fit a finger, that moment I felt like a slut and it felt good, I kept working on sucking his yummy cock, but in the moment when I was about to finish it in my mouth, I felt another hand on my right thigh, rubbing me like I liked and getting closer to my groin too, I wanted to say something but he grabbed my head and started thrusting it in and out of my mouth harder until I could feel several spurts of semen, it was a lot, that instant between consciousness, I swallowed everything and ran out of the cinema without looking back thinking about what I had done and what would have happened if I had stayed a little longer, I cleaned my mouth on the way as discreetly as possible, I could still feel how wet everything had made me, I arrived at my house, got undressed to sleep, threw myself onto my bed and started masturbating thinking about that moment and fantasizing if I had stayed, finished and felt a bit guilty until I fell asleep, the next day all I thought about was how I would get up the courage to do it again, since until today I haven't done it again, I want to but don't know how to fulfill them, I even thought about going further with two at once, but I don't know, I just want to repeat it with someone who trusts me and is as crazy as me.
