UT buddy

This is my friend M from UT I met not long ago. We met through my friend S and I always thought he was really cute. We hit it off right away and hung out alot. He became my "movie" buddy. We've flirted with each other but nothing really has come of it. I told S (one of my gal pals) during happy hour that I thought he was really cute. She giggled and told me that she's seen me flirting with him. I told her it was just harmless fun and he went along with it too. She told me that she had hooked up with him and he had a huge cock. That intrigued me. So, I decided from that moment on I wanted to see "it" for myself. I decided to actually step up my flirting and see how I could get into his pants. Every time we hung out we always ended talking about sex. I know he's straight for the most part because he would tell me about all the girls he would talk to. He would even tell me stories about them. We went back to my apartment to hang out. We started talking about sex like we always do. We started getting into more details about what we like doing sexually. I told him how much I love giving head. He said he's never been able to cum with just someone sucking him off. He usually has to jerk off and than let them suck it when he cums or just jerk off. I told him that I've never really had that type of problem. He laughed and smiled. He asked if I was that good. I told him I've been giving head since I was 13yrs old. I had plenty of practice. I told him I could show him someday if he wanted? He just smiled and gave me a small little grin. "I guess you could do that?" M said while he adjusted himself. "Really?" I was kinda surprised he was so forward to answer me. M just smiled, "Yea, I'm kinda easy that way.". I took it as my cue. I leaned over and grabbed his cock through his cargo shorts. He had a semi and from what S told me...she wasn't lying about the size. I grabbed his cock and got between his legs. I nibbled on it through his shorts. I could feel it getting harder in my hand. I undid his shorts and pulled them down. His cock automatically poked out through his boxers. He looked so hot sitting there with a helpless goofy lustful grin and a huge cock poking out waiting to be sucked. I immediately grabbed his cock and licked the head. He moaned softly and closed his eyes. I thought to myself, I'm gonna give him the best head of his life and make sure he gets off with just my mouth with no help from him. I began my "mission" to do so. I licked the head very lightly. I put my mouth on the head and gently sucked on it. Than I opened my mouth and softly sucked the rest of his cock. I started soft and slowly sucking his cock. Licking the head with my tongue the entire time. He was loving it. He would look at me every once in a while, while I sucked it. I squeezed his cock and a drop of precum gathered on the slit and swirled it around the head with my tongue. He grabbed me by the hair and moved my mouth off his cock. He grabbed his cock and squeezed more precum out of his cock. I stuck my tongue out and licked it. He slapped my mouth with his cock. He pushed me down on his cock and I started sucking it. I went all the way down on his cock. I deepthroated him. He let out a huge moan saying, "OH MY GOD!" and grabbed the back of my head and held me down on his cock. "No one has ever deepthroated me before. That was awesome." M said with just a huge surprise on his face. I decided to deepthraot him again. He let out a huge gasp. I stayed on his cock for about 10 seconds deepthraoting him the entire time. He was so turned on. His cock was so hard in my mouth. I again started slowly sucking his cock. Than gradually started sucking harder and adding more suction. I looked up at M and he had his eyes closed and mouth wide open. As I kept sucking him I felt his hands behind my head. I knew he was getting ready to blow. He started whispering and repeating "Oh, God." while he pushed my head down. That lasted about 30 seconds. "I'm gonna cum!" M yelled and he pushed my head all the way down his cock. I grabbed his hips and deepthroated him while he shoot a huge load down my throat. He was arching his back, leaning forward and his legs were twitching a bit. As soon as he calm down he was sweating and breathing heavily. I squeezed his cock and licked up the last few drops of his cum. He twitched some more while I did this. He finally opened his eyes and smiled at me. "WOW! I've never cum like that before. That was amazing.". I smiled at M. "I'm glad you liked it. Maybe you can let me do it again sometime? I would love to swallow another load." I told M while I was still sucking and licking his cock.  "Fuck yea! That was the best fucking head I've ever gotten. You're the only who has gotten me off like that. You think I'm gonna say no to letting you suck me off again? Fuck no. I could use it everyday. But Jasen I am 18 and if you keep sucking it, it won't go down.". We both laughed and I told M I would suck him off everyday if he let me. Well, I haven't sucked him off everyday but he did text me the next day wanting to drop by for a quick nut. I've sucked him off a few times since than. I don't know if I should tell S? She hasn't asked me about him but I haven't told her yet. Maybe over happy hour again?

P.S.
I got the cock picture from him the last time I sucked him. I told him I didn't know if I had time to. I was running late for work. He text me the picture, saying this is what he had for me. Love how forward he is.
