Second time taking dick! [MM]

So the second time I was ever with a guy I was still 18, it only happened a few weeks later, and I was again drunk.
So I went out with my friends and we went to this club where you had to pay £10 to go inside. It was already 3am so I said to the lads and lasses that I’m not paying that and just gonna get a taxi home, we all said our goodbyes and everyone went inside. I made my way down to the city market where the city council legit taxis park, a bit expensive but trustworthy. But I was so drunk that the taxi driver told me to come back a bit less drunk because I was swaying that much.
I went into the market which was all empty, because it’s 3am, and sat on a bench. I was browsing my phone passing time and a guy sat next to me. We started chatting about how our nights had gone, why we were alone and all that. He was a Middle Eastern guy, about 42, had a beard and at least 3 inches taller than me (I’m 5” 11). Somehow the conversation got onto sex, and then porn, and I had a video on my phone of three women on a bed having a threeway. It was twenty minutes long and we started watching it. We got about 5-10 minutes in and he put his thumb and finger on my chin and made me face him, then proceeded to kiss me. He stuck his tongue in my mouth and I was so drunk that I just let it happen. I made an involuntary moan and he stopped kissing me, and said (I remember this exactly) “I know a quiet place, want to kiss my cock tonight?” And my cock got hard instantly! I said yes and he took me by the hand and we went to a dark alley by the side of a shop and kissed me more. It was so dark we couldn’t see anything. He grabbed my hand and I felt something warm, it was his cock! It was honestly the biggest I’ve ever felt – Even 9 years later! He undid my belt and got my cock out, only 7 inches he wanked me a small bit then stopped.
I felt his hands on my shoulder and I fell to my knees, and I began sucking his cock.
It was amazing, it just felt… Right. He began to thrust into my mouth and I began moaning involuntarily, I didn’t understand why but he enjoyed me moaning as he said “Keep moaning, bitch! I want to use you all night!” After maybe 10 minutes of sucking him he filled my throat with his cum! (And I discovered my fetish for being used anonymously)
