Bobby reached behind and tapped his butthole. "Right inside there. Really deep."
The doctor dipped his middle finger inside Bobby and hooked it downward. "Right there?"
Bobby bit his lower lip and nodded.
"I've got just the cure for that." The doctor took his large cock into his hand and pressed it against Bobby's hole, sinking forward slowly as the young man's body opened up to him.
I watched in astonishment, wondering how something so big could fit inside such a tight little body. But Bobby seemed to take it like a pro. He moaned with pleasure as the doctor effortlessly glided deep into his hole.
With their bodies connected, they moved in rhythm together. When the doctor pulled out, Bobby pushed back. Then they both gasped as they crashed together again.
In and out.
Over and over.
My own cock was raging hard and there was a deep stirring inside me. I began to realize that a tickle from the doctor's fingers wasn't going to be enough to satiate me. Not after seeing this. I wanted more. I wanted what they had.
That carnal connection. A shared understanding of each other's needs. Two bodies melting together. I wanted to feel it too. Hot skin against skin, a hard organ thrusting its way inside me.
This was human nature, and in that moment, the shame and embarrassment for the feelings I'd kept locked away seemed to dissipate. It was only instinct at work.
Without really thinking about what I was doing, my fingers found their way to my shirt and lifted it over my head. The fabric was too constricting. My body needed to breathe. Then my fingers found their way to the top button of my jeans. I popped it open, then down came the teeth of my zipper, which was scraping mercilessly against my throbbing cock.
Even my posing strap was too tight against me. Down it went too. Then I was sitting there with my bare butt cheeks pressed against the rickety chair watching the magic happen.
Doctor Doyle was really giving it to Bobby good; thrusting hard and deep into him, jaw clenched and muscles flexed as he held the boy steady by the hips with his big hands. Their rhythm was faster now, more fervent. Bobby had reached between his legs and begun stroking his cock. The look on their faces told me they were close to reaching the finish line together.
Meanwhile, my cock was swollen and dripping with pre-cum. I wasn't ready for the show to be over yet. Not yet.
I wasn't myself anymore. As if possessed by a bolder, braver incarnation of my spirit, I yelled out, "Stop!"
