It had only been a fleeting moment; perhaps a minute of pure joy when all doubts about my bisexuality had been sucked out of me. It had been a carefree night, myself, Rob and Dan just fooling around, drinking vodka, laughing, planning all sort of improbable escapades.
It was about midnight and Dan asked us if we were hungry. He scampered off to the kitchen in his tiny flat to rustle something up, leaving Rob and me half watching the TV. Rob's head suddenly dropped limply on my lap, and I thought he'd fallen asleep, victim of the excessive cheap vodka.
His hand rubbing heavily on my dick through my jeans alerted me to the fact he was very much awake. I was shocked, too shocked to resist, and deeply embarrassed when my dick promptly stood to attention. I felt it scrape past the metal fastener as Rob unzipped me and applied what little coaxing it needed to make its way coyly out of my flies.
I wanted to move away, frightened Dan would walk in any minute and that my secret desires would be exposed, but I simply couldn't. Transfixed, I took a deep intake of breath as Rob applied first his tongue, then his lips, to my throbbing glans.
He plunged his head down, taking my penis almost fully in his mouth, and proceeded to apply himself with vigour to the job in hand. It was only my third blow-job ever, the other times with women, but this was by far the most erotic.
Within barely thirty seconds I knew I had to shoot my load, and the slamming of cupboard doors in the kitchen indicated that Dan couldn't be far from making a reappearance. Rob worked furiously to bring me to climax and, as Dan's footsteps could be heard coming up the corridor, I groaned silently as my cum filled Rob's mouth in four or five ecstatic muscular spasms.
I was still trying to press my still-erect prick back into my pants, while Rob wiped my cum off his lips with the back of his hand, as Dan stepped back into the room with some cheese and crackers. His knowing look indicated that he realised we'd been up to something, but he said nothing.
He never did: not once down the years. It was all over so quickly, yet the memory of it all has stuck in my mind all this time as if it was yesterday. I've never forgotten it, and even now whenever I meet Rob I feel that hard bulge in my crotch.
