“A” stands for

When he came, I felt something inside him squeeze and press hard against my finger, in the same pulsing cadence as the squirts of sperm that had shot from his head. I didn’t make the connection yet of course. Our sexual education classes had covered only basic gender anatomy, not all the details of the male genetalia’s inner workings and of the significance of the prostate gland in the orgasmic process. And now we had arrived at a crossroads of some sorts. I was sitting between his pulled-up knees, his swollen-red cock still semi hard and twitching, glistening from my spit and his cum, his asshole gaping and beckoning. I looked down at it, and saw the tip of my own raging boner point straight at it, as if it tried to lead me somewhere. I searches his eyes.

Did he actually nod at me, or did he just signal me some other way, indiscernible to the eye, but clear to all my other senses? I didn’t know then, and I still don’t know now. So I acted on instinct and desire. I crawled up closer, positioned the head of my cock against his beseeching asshole, and entered him. Up till that moment I could fool myself that it didn’t mean anything, that it was just boys dicking around, just some first sex experimentation without any feelings or commitment involved, but not anymore. I was now inside of him, really inside! The tightness and warmth engulfing my member rivaled the best of what he had done with his mouth, and added an undeniable aspect of intimacy. We exclaimed our appreciation of this in unison. I took a moment to acclimatize to this new situation. Thanks to my spit, I had glided easily inside him, almost without resistance. I felt a bit unreal, somewhat disconnected, and looked between our bodies to look for a link to reality. My cock was deep inside him alright, all the way up to the hilt, his own cock and balls seemed to sprout from my belly, but upside down. He clenched his sphincter, which I felt like a warm and strong squeeze to my dick. He flinched, looked a tad uncomfortable, but he adjusted his position a bit and then relaxed. “Am I hurting you”, I asked a little worried.
