I stumbled slightly up the stairs to the 3rd floor, still trembling from our previous stairwell fuck. Before I had a chance to ask Maestro if we should go up another flight to the next landing, he grabbed my shoulder and pushed me face first towards the concrete wall. His hot breath on the back of my neck and ears contrasted the cold wall against my cheek.
"We didn't finish what we started last time, did we, Marie? Maestro whispered in my ear. "I'm going to fuck you again. Harder! I hope you're still wet," he cautioned. I turned toward him and saw the telltale wicked grin on his face. I shivered against the wall.
"Ye ... sssss ... Maestro. I promise I'm still wet for you." Totally submitting to his control, especially in public, makes me hornier than anything I could have imagined.
"Hmmmmm ... good girl, Marie. You are ready." I felt his cock pressing against my ass, and my thong, still wet from our before-lunch cum. I reached behind me in vain, trying to adjust the thong, but Maestro pulled it down too quickly. He then caught my flailing hand, and held it over my head. "You won't need your hands, Marie. So they stay here." He grabbed my other hand and with just his left hand, immobilized both my hands.
A loud slap, what could have been his hand spanking my ass, was instead the sound of my belly hitting the cold concrete wall. "Aaaaagghhhhhheeeeeeee," I couldn't control my scream, failing to muffle them against the wall, as Maestro's cock filled my pussy in a hard thrust, almost harder than anytime before. He withdrew as quickly as he filled me, then slammed me again, even harder. I drooled against the wall, only silent screams escaping my lips now. I rocked my body as much as I could against the wall, preparing my pussy for the next onslaught.
