My name is Sophia, and I was just trying to get in shape for summer.
I joined an exclusive 24-hour gym two months ago. The facility was luxurious, expensive, and had the best personal trainers. I was assigned to Valeria Kane — the head trainer of the women’s program.
Valeria was 29 years old, 5’11”, with a body that looked like it had been carved by the gods. Long dark hair always tied in a high ponytail, sharp emerald eyes, full lips, massive firm E-cup breasts, a tiny waist, wide powerful hips, and thick, muscular thighs. She moved with the confidence of someone who knew exactly how hot she was.
From the very first session, I couldn’t stop staring at her.
Especially at the enormous, obscene bulge in her tight black compression shorts. It was impossible to ignore. Every time she demonstrated squats or lunges, that thick bulge swung heavily between her legs. I told myself it was just muscle or padding… but deep down I knew better.
One Thursday night, I stayed late for a private session. The gym was almost completely empty. Valeria had me doing heavy squats in front of the mirror while she spotted me from behind.
“Eyes forward, Sophia,” she said sternly when she caught me staring again.
I blushed hard and looked away.
After the session ended, I went to the women’s locker room to change. I thought I was alone. My body was still buzzing with adrenaline and arousal. I sat on the bench, pulled my shorts to the side, and started rubbing my swollen clit while thinking about Valeria’s bulge.
I was moaning softly, fingers moving faster, getting close to the edge…
The locker room door opened with a loud click.
Valeria stood there in her tight tank top and compression shorts, staring directly at me with my fingers buried deep inside my dripping pussy.
Time froze.
Her lips slowly curved into a dark, predatory smile.
“My my… what a naughty little slut I have as a client,” she said, her voice low and dangerous. “Playing with your cunt in my locker room while thinking about me?”
I yanked my hand away, face burning with shame. “Ms. Kane — I’m so sorry! Please don’t fire me, I’ll quit right now, I—”
She stepped inside and locked the door behind her. The sound echoed like a prison cell.
“Stand up,” she commanded.
I stood on shaky legs, my shorts still pulled to the side, pussy juices running down my thighs.
Valeria walked over slowly, towering over my smaller 5’4” frame. She grabbed my chin roughly and forced me to look up at her.
“You were staring at my cock the entire workout, weren’t you?” she whispered. “And now you’re fingering your desperate little pussy thinking about it?”
I couldn’t deny it. I nodded, tears of embarrassment filling my eyes.
She smiled. “Good. Honest little whore.”
Without warning, she pulled down her compression shorts.
Her massive futanari cock sprang free — 11 inches long, thick as my wrist, heavily veined, with a fat swollen head already leaking precum. Below it was a smooth, puffy pussy.
I gasped loudly.
Valeria grabbed my hair and forced me down to my knees.
“Worship it,” she ordered. “Show your Mistress how sorry you are.”
I hesitated for half a second.
She slapped my face with her heavy cock. “I said worship it.”
I leaned forward and started kissing her massive futa cock. I licked every inch, sucked on her heavy balls, and tried to take the thick head into my mouth. Valeria moaned in pleasure and started fucking my face, holding my head in place while thrusting deep into my throat.
“Look at you,” she groaned. “Such a perfect little cock worshipper. This is what you were made for.”
She used my throat brutally for nearly twenty minutes until I was gagging, drooling, and crying. Then she pulled me up, bent me over the locker room bench, and rubbed her huge cock against my soaked entrance.
“Beg for it,” she demanded.
“Please… Ms. Kane… I can’t…” I whimpered.
She slapped my ass hard. “Beg.”
“Please Mistress Valeria… please fuck me with your big futa cock…”
Valeria thrust into me in one powerful stroke. I screamed as she stretched my tight pussy wide open. She was so deep I could feel her in my stomach.
She fucked me like a savage — hard, fast, and merciless. Her heavy balls slapped against my clit while she gripped my hips and pounded me.
“You’re mine now,” she growled. “Every single day after your workout, you’re going to stay late and drain my futa cock. Do you understand?”
“Yes! Yes, Mistress!” I screamed as I came violently around her massive cock.
She didn’t stop. She kept destroying my pussy, spanking me, choking me, and calling me her personal cum dump. When she finally came, she buried herself to the hilt and pumped me full of thick, hot futa cum. There was so much it overflowed and ran down my legs.
But she was still rock hard.
She made me clean her cock with my mouth, then sat on the bench and forced me to ride her. I bounced on her huge futa cock while she sucked on my tits and slapped my ass.
From that night forward, I became her personal fucktoy.
Every day after workout, I would crawl under her desk and suck her massive cock while she took business calls. During lunch breaks, she would lock her office door, bend me over her desk, and fuck me senseless. She made me wear a butt plug all day so I was always ready for her.
Some nights she would keep me in the gym after closing and fuck me for hours on the mats — facesitting me, tittyfucking me, and filling every hole with her thick futa cum.
She was completely dominant and insatiable.
One night she tied me spread-eagle on the weight bench and fucked me for nearly four hours straight, pumping load after load into my womb.
“You’re going to carry my futa baby one day,” she whispered while filling me again. “And you’re going to thank me for it every single day.”
I was completely broken. I lived for her thick futa cock.
Valeria Voss didn’t just fuck me. She owned every inch of me.
