Cool question. I have been bi for around half a year now (been stupidly curious for two decades). When I first started in the scene I was super hesitant to even let a guy blow in my mouth, period. The thought was Uber hot but I would always bail at the last second and have him bust on my neck or chest. It wasn’t until I met my blowjob buddy that all that changed. After maybe 3-4 weeks of sucking each other off 3-4 times a week we agreed to abstain for 10 days, and spend and entire Sunday edging each other. Sure enough, that Sunday came and it was the most erotic horny fun filled Sunday on my life. We edged sucked each other from 8am till 11pm. We were literally crying in pain. We agreed that this was too much and that the last run at our cocks would be the last for that night as we both needed to orgasm like our life depended on it. So he was up first, slowly sucking him with my own balls full of cum, sucking and sucking, and being so horny I was really feeling his orgasm work up, moaning together, he had his hand on the back of my head but in a gentle way. I could feel he was close as his balls were going into twitch overdrive, literally yelling at me he was going to cum. The feeling was just off the charts for me, normally i would stop sucking and jack him off but I just kept sucking and sucking. After 5 or so seconds he started to blow in my mouth, and having not cum for so long, my mouth was literally filled so much so I had to take his cock out of my mouth, which he was still shooting cum, and then swollow, and then continue sucking him which was around another 4 or so ropes of cum. I literally almost blew my load there and then.
Needless to say, I have him blow in my mouth 3-4 times a week now, and have sucked off a few other guys in the process, and have had their load in my mouth as well.
cum fucking rocks!
