How I had my introduction to bisexuality

This still gets me hot nearly 40 years later

It was a hot summer and I was in my teens. My friend Alan had come round and unusually it was just the two of us messing around. I still lived at home and we had a pool so we cooled off and mucked about in the pool. He was into football (soccer) and was in silk Liverpool United kit, I was not so sporty and just wore trunks. The pool was at the back of the house with only a small window in the house wall and a wall between the garden and fields so not overlooked. There were changing rooms where I got to see the other lads naked briefly, some always covered up with towels but I remember because I was fairly developed for my age I usually went without covering up in case it encouraged others to do the same.
Previously I’d had a jacking off experience with a friends older brother and hormones were raging with no real outlet! I don’t know why but I just took a chance in a crazy moment and while we were drying off on the lawn (we weren’t going to be changing into other clothes yet) I touched his bum from behind. He froze, I froze, had I crossed a line? Was I going to be exposed and humiliated when he blabbed about me making an advance to a guy? I’d already been thinking of excuses but they weren’t very plausible!
He did nothing so I did it again and he made an agreeable sort of moan/grunt. I’d never really tried seduction before! I just continued for a while rubbing his bum through the shorts while he swayed around a bit and made little noises. Eventually I put my chest against his back and reached around the front to find a big hard bulge in his short. I rubbed it a while, tried putting my hand in the waistband but he pushed it away and put my hand back on the bulge. I carried on groping until he turned round and kissed me full on the lips. Then frenched me. Id never done it before, our teeth clashed, but I soon understood what to do.
“Someone will see”, he said, so we went into the changing rooms. I pulled my trunks down to release my cock and tried doing the same to him but he resisted. I carried on groping as he seemed to like that but then he said “touch it”. I put my hand into his crowded shorts feeling the pubes and his balls then massaging his cock. By now he was jacking mine. “Stop, cum will stain silk and my mum will see” he said. I stopped but now with no complaints from him I pulled his shorts down enough to free everything. He was saying stuff like “I’m so horny” and jacking his cock himself now so I watched as he got off, I knelt to get a closer look and I don’t know why but it felt natural to put my mouth on it. He came in my mouth and shuddered. After this he jacked me off but wouldn’t blow me at that point.
This started a crazy summer and I lost touch with him after school but used this memory as a favourite fantasy for wanking. I bumped into him in my 30s, nothing was said about this but I wondered if he would ever do it again. I never followed it up regretfully!
