[MKON-132] My Girlfriend’s Chiropractic Visit Turned Into a Wild Encounter Behind the Curtain

The air in the chiropractic clinic was thick with the scent of antiseptic and something else—something raw and desperate. My girlfriend was on the table next to me, her massive tits straining against her tight uniform as the chiropractor worked her over, but all I could focus on was the sound coming from behind that thin curtain. It started as a low moan, a soft ‘ohhhh’ that sent shivers down my spine, then built into a frantic, breathless chant: ‘Ohhhh ohhhh ohhhh nnnnhhh.’ I knew that voice. It was Mikkan Suzu, the new assistant, and from the wet, slapping sounds and her choked cries, she wasn’t getting a standard adjustment. I could picture it perfectly: her on all fours, that crisp uniform hiked up, taking it deep from behind while my girlfriend lay oblivious beside me, her own big tits heaving with each innocent stretch.

My girlfriend’s treatment seemed to drag on forever, every creak of the table syncing with the lewd rhythm from the other side. I heard Mikkan’s moans grow louder, more urgent, punctuated by the slick, wet noises of a hard, relentless pounding. She was getting a very different kind of massage—one that left her gasping and begging, her body shuddering through a solo act that was anything but solitary in its intensity. The curtain might as well have been transparent; I could almost see the sweat glistening on her skin, the way her tits bounced with each thrust, the final, messy release as she took a hot, thick load deep inside, a creampie that left her whimpering and spent.

By the time my girlfriend’s session ended, I was a wreck. The sounds had painted a vivid, depraved picture: Mikkan Suzu, used and filled right there in the clinic, while I played the cuckold, forced to listen and imagine. As we walked out, I glanced back, catching a glimpse of Mikkan adjusting her uniform, a flushed, satisfied look on her face. My girlfriend chatted innocently about her sore back, but all I could think about was that hidden scene—the big tits, the uniform, the massage that turned into something so much filthier. It’s burned into my brain, every moan, every slap, every last drop of that secret, stolen pleasure.
