I pushed open the door to the gloryhole booth and locked it behind me. My dick was already stiff in my jeans. I unzipped, pulled it out, and shoved it straight through the hole in the wall. The air on the other side felt cool for a second, then warm lips wrapped around the head and sucked hard.
"Fuck yeah," I muttered. The mouth went straight to work, no teasing. A tongue licked the underside while the lips slid down my shaft, taking half of me in one go. I grabbed the wall and thrust forward, feeding more cock through the hole. Whoever was on the other side knew what they were doing. They bobbed fast, sloppy, spit running down my balls.
I heard a woman moan around my dick. It sounded familiar but I didn't think about it. I just fucked the hole, driving my cock into that wet mouth. She gagged once, pulled back, then went deeper. Her hand came through underneath and cupped my balls, squeezing them while she sucked.
"Take it all, slut," I growled. She answered by swallowing another inch. Her throat squeezed the head of my cock. I pumped my hips, slapping my balls against the wall with every thrust. Spit and precum dripped onto the floor on her side. She kept moaning, the sound vibrating up my shaft.
After a few minutes she pulled off. I felt her fingers wrap around my cock and stroke it a couple times. Then something wet pressed against the tip. It was her pussy. She had stood up and backed onto the hole. I felt tight cunt lips part around my dick as she pushed back. She was soaking wet. I slammed forward and buried myself in her in one stroke.
She cried out on the other side. I started fucking the gloryhole like it was the last pussy on earth. Hard, fast strokes, the wall shaking each time my hips hit it. Her cunt gripped me tight, hot and slick.

Every thrust made wet sounds. She pushed back to meet me, taking every inch.
"Goddamn, this pussy is tight," I said. "You like getting fucked through a hole, don't you?"
She answered with a low moan and shoved back harder. I reached down and grabbed the edge of the hole for leverage, pounding her. My balls slapped against the wall. I could feel her juices running down my shaft and dripping off my balls.
We fucked like that for a while, raw and nasty. Then she pulled away again. I thought she was done but a second later her mouth was back on my cock, sucking the taste of her own cunt off it. She went deep, cleaning every inch with her tongue.
I was close. My balls tightened. "I'm gonna cum," I warned. She didn't pull off. She sucked harder, jerking the base with her hand. I exploded down her throat. She swallowed every spurt, moaning the whole time. Some cum leaked out the corner of her mouth but she licked it up.
I pulled my cock back through the hole, breathing hard. Then I heard her voice clearly for the first time.
"Mark? Is that you?"
My blood went cold. It was my mom's voice. I froze. On the other side of the wall she gasped.
"Oh my God. Oh fuck. Mark, baby, it's me."
I stood there, dick still half hard, cum dripping from the tip. Through the hole I could see her eye looking back at me. We were both quiet for a second.
Then she whispered, "Don't stop. Please. I need more."
My cock twitched. I looked down at the hole. Her fingers came through, reaching for me. I stepped forward again. She grabbed my cock and pulled it back through. Her mouth closed around it, sucking it clean and getting it hard again in seconds.
This time I knew exactly who was on the other side. My own mother was sucking my dick like a whore. The thought made me throb in her mouth. She worked it fast, dirty, no hesitation now that the secret was out.
She stood up again and backed onto it. I slid into her pussy for the second time, knowing it was my mom's cunt. I fucked her harder than before. She moaned louder, saying my name between gasps.
"Mark, fuck your mother. Use that hole. Fill me up."
I slammed into her, the wet sounds louder now. She came first, her pussy clenching around my cock, juices squirting out around the hole. I kept pounding through it until I shot another load straight into her.
We stayed like that for a minute, my cock still inside her through the wall. Then she slowly pulled off. I heard her sit down on the other side.
"Come around to this side," she said, voice shaky but hungry. "We're not done yet."
I zipped up just enough to walk out, then went into the next booth. She was waiting, on her knees, mouth open. We didn't talk much after that. We just kept going, raw and direct, until both of us were spent and the floor was a mess.
When we finally left the booths we didn't say a word in the hallway. But the look she gave me promised this wasn't the last time we'd use that hole.
