The Moment Experimenting Turned Into Something

It started out as show me yours and i will show you mine. At first it was nothing. I touched his and he touched mine. Some times we suck each other until we got bored. Most times we watch porn until we got horny enough to jerk off. At an early age, you didnt really go to orgasm, it was more exploring.
I remember the first time i saw him cum after jerking off. His cock swelled, the vein ballooned and his cock started to throb. Then shot after shot flew out of the tip and dripped on his hand and chest. We did this everyday after school or sports practice. I couldn't take my eyes off this sight. My own orgasm never looked that amazing. I wanted to feel that throbbing in my hand so the next day i asked him if he could cum in my hand. I felt that vein thicken, his dick throb and all that cum dripped all over my hand.
That was the first memory i have enjoying bisexual sex. Before that i wasn't that into it. Often i would gag a little during oral, even though he was small. The thought of a cock in my mouth bothered me but i wanted him to suck mine too so i pushed through and eventually enjoyed male on male sex more than him even though he forced the action most times.not much later he would force me to take his load in my mouth. He tasted so bad and he came so much it would spill out of the side of my mouth. I was getting tired of tasting his nasty juices so one day i decided to try swallowing it instead. It was so much to swallow but i tasted it less. Unfortunately it grossed him out. We continued to do stuff well into our 20s but as i started to enjoy male on male sex, it turned my partner off. Toward the end of our relationship i would offer my mouth or ass to finish but often he rather jerk him self.
