Sucking cock in an alley

Last night about 6pm I was Downtown when I random tall black man said he liked my pants. I said thank you then he asked me if I minded bending over in front of him. I said ok no problem and did so. Before I had bent over I was getting hard so after I stood up I said "sir will you allow me to suck your dick? I don't want anything in return except a mouthful of cum". He didn't say anything just grabbed my hand and led me down the street to the alley. He told me to get on my knees in this doorway and had his half hard 9"mega thick cock out when I looked up. I grabbed it sticking his member in my mouth and went to sucking. Slowly at first but once he was rock hard I went faster sucking harder. After about ten minutes I stopped for a sec and used my hand to stroke him and told him to fuck my mouth and throat until he came. He obliged grabbed my head behind the ears forcing me to deepthroat him. I gagged but didn't have time to think about anything but sucking as he pounded my face hard. So hard that it hurt a little. For the next 10 or 15 min he didn't slow down or stop until finally I felt his huge cock swell and he said he was about to cum. 30 secat he held me by my hair told me to stick my tongue out and I looked at his cock right as he exploded covering my face with his cum. When he finally stopped cumming he stuffed it down my throat again then cock slapped me and put his member back in his pants. He thanked me saying maybe we'd meet again. Slapping my face hard then turned and walked off. I j/o then got on my bus. It wasn't until a lady sitting across from me asked if I needed something to wipe the cum off my face and beard that I remember he gave me a facial
