I likely shared this elsewhere on JUB, but sharing it here fits this thread:
I gave my first blowjob to a fraternity brother in college. It was during pledge initation week, they were required to provide a night of stag films for us actives to watch. While watching, most (all) of the brothers were adjusting their crotches, rubbing themselves, as they watched the action. Afterwards my roommate and I went back to our room. As he swept into the room and stripped to his undies for bed (which showed a throbbing hard dick), he announced to me that he was gonna jerk off, and I could (should) too. He put Paul Simon's album "50 Ways to Leave Your Lover" playing softly on his stereo. I couldn't see him jerking, but could hear his fap, fap, and soon was stroking my hardon (not due to the movies, but to the music of his moving hand). He then whispered, "Hey, get over here and blow me". He didn't need to ask twice, I lept out of my bed and his cock was soon deep in my throat (I'm hung, he was of a comparable size). I sucked a bit, paused and studied his hard cock in the blacklight of our room. I licked up and down the shaft, suckled on his balls, he pulled me back to the shaft and speared his cock into my throat again, holding me on it, pushing me down on it, as he began thrusting his cock in and out of my throat. I had never sucked a cock before, but sure wanted this to last. However, he was eager to blast his load - he won in that pause or cum contest and fired his loads down my throat. I wasn't willing to surrender his cock, so kept it in my mouth, continuing to suck on it (I didn't realize I was giving him oral post-cum torture), but he realized it, the pleasure on his sensitive cock intense, and he tried his best to get my mouth off of his cock - he failed. That sensitivity faded and he relaxed, allowing me to suck him to another hardon, which lasted a long time, an eternity of time (I really don't know how long, but I'm guessing an hour or more), before his cock again gave up gallons of cum. I could have kept on sucking, but this time he did succeed in getting his cock out of my eager mouth. He ordered me to jerk off to my own cum, which I obeyed. As soon as I came, he grabbed his towel and fled to the shower, I crawled back into bed, reliving the memory of giving my first 2 blowjobs. He wouldn't talk about that evening for the remainder of the semester. I thought he was feeling guilty or something. Turned out, he was desiring me to ravish his cock again, but couldn't figure out how to demand that without seeming gay.
My fraternity had everyone switch roommates each semester, so the next semester we weren't rooming together. Over spring break I stayed in town for a part-time job. In the middle of the week, he showed up about 10pm, inviting me into his room. Within minutes we were in a 69 position, and spent the remainder of the night (until about 5am) sucking one another, with lots of random cumming. My first time being sucked, my first time enjoying the pleasures of 69ing. I can't count how many times I came, or he came, but a lot of cum flowed, not one drop spilled. That is when I learned the previous semester he'd been very badly wanting me to be his nightly cocksucker - sucn a lost opportunity. I also learned he'd been sucking and 69ing with one of his cousins long before I got my mouth on his cock. I continue to jerkoff to those memories.
