The ”I” in bi

“I guess so”, I said a little sheepishly. I tapped off like he had done, and started tucking away. He still stood there though, in the same defiant pose, his cock no longer limp but hardening yet again.
“Wanna go for best two out of three?” He was definitely mocking me know. I couldn’t imagine going again so quickly, certainly not since I had spent so much effort the first time.
Then, words again left my mouth before my mind could stop them. “You remember the time…we used to, you know…suck?”
He shrugged once again, not appalled, but dismissing it as irrelevant. Or so he tried.
“Sure I remember, but that was years ago. We were just kids.” By now his cock was a raging boner again.
“You still think about that?”
He hesitated noticeably, a little taken aback. “Sometimes. Why do you ask?”
And there were those words again, running off before I had given them permission.
“Want me to suck you? like I used to?”

He swallowed, his hand unconsciously moving down to his cock again, probing his erection. His cock definitely said yes, I could tell when it jumped up and down as he gently started squeezing it.
I had crossed a border anyway, so when his reply didn’t come immediately, I just approached him, dropped to my knees and closed my mouth over his pecker. He let his hands fall beside him and sighed in surrender.
I started sucking him like I used to, like drinking from a straw, but his cock definitely wasn’t the soda straw it once was. It was thick and hard, tasted of what I realized must have been his semen, and immediately filled my mouth completely, punching in the back of my throat as he started rocking his pelvis back and forth in cadence with my sucking rhythm.
