So I identify as bisexual now, but there was a time that I didn’t. Went through high school being sure I was 100% straight, despite one occasion where I masturbated under the covers with a friend at a sleepover.
Fast forward to when I was 21 (I’m 27 now, so 2016), and my best friend from high school wanted to sleep over to catch up as we hadn’t hung out in ages. We slept on separate air beds next to each other, and got talking about sex during the night. This made us both horny and we were clearly touching ourselves under the covers, so eventually we both ended up totally naked with the covers off, masturbating next to each other. This time, however, we switched hands and started stroking each other. Feeling another guy hard in my hands for the first time was an awesome experience! After that he offered to go down on me and sucked me off until I came in his mouth. I was too nervous and confused to return the favour, so I stroked him a little more and then he took over and made himself cum.
