“A” stands for

It was my turn now. I gently pushed him away, denying him my cock to which he whimpered a bit pitiable. I was glad he had given up his reservations and had opened up to this new realm of enjoyment we could discover together.
I pushed him further back and let him lay on his back. I took a moment to step out of my pants and pull my shirt and sweater over my head, discarding it all in a corner.

Where Dave had quite an impressive torso already – he was a soccer player of a somewhat promising level – I was just a boy that had gotten taller. My shoulders and chest hadn’t started expanding like his, and my legs and buttocks were just as skinny as they always had been. But none of that mattered. I admired Dave’s physique, but apart from his groin, there was no adoration. Not like how I fantasized about the girls in my class, imagining their budding teen breasts and enchanting asses and legs. Dave was just my best friend, and a cock to suck.

I kneeled at the foot of the improvised bunk, between his bent knees. I took my time unbuttoning his pants and pulling down his zipper. I felt impatient to taste and feel him, but I really wanted to enjoy this to the fullest. Anticipation felt as much an essential part of the experience as gratification. I reached under his butt and grabbed the rim of his pants. He lifted his pelvis to allow me to strip his trousers off. When his massive boner sprung free, I just eyed it hungrily, savouring the moment of first contact just a little while longer. I rubbed my hands over his calves, knees and thighs on my way back up, despite myself enjoying the feel of his strong muscles under my touch.
