Maxim stirred on the cold lab table, his mind foggy from the procedure. The fluorescent lights buzzed overhead as he sat up, noticing the impossible weight between his legs. A shadow fell across him, and Dr. Elena Voss stepped forward, clipboard in hand and a smirk on her lips. "Well, well, our eager student volunteer wakes up. How does the new equipment feel, Maxim? I designed it myself—pure bull power for that scrawny frame of yours."
"You turned me into some kind of experiment?" he shot back, voice rough but laced with curiosity. Elena laughed, circling him like a predator. "Experiment? Darling, I gave you an upgrade. Most men would kill for a cock like that. Feel how heavy it is already? Horny yet?" Her eyes gleamed as she leaned in, her lab coat slipping open to reveal a fitted blouse. Tension crackled; Maxim's new bull cock twitched, growing hard and throbbing against his thigh.
Elena didn't wait for permission. She shed her coat and straddled the table edge, strong hands gripping his shoulders. "Let's test the results properly. I've been waiting for this." She freed his massive cock, stroking its veined length with approval. "Thick, veiny, and dripping already. Impressive." Maxim groaned, but she silenced him with a witty retort: "Save the moans for when I'm riding you. This pussy doesn't submit to just anyone."
She dropped to her knees for a teasing blowjob, tongue swirling over the head before taking him deep. Her mouth worked expertly, saliva dripping down his shaft as she pumped with one hand. Maxim panted, hands in her hair, but Elena stayed in control, pulling back with a wet pop. "Not yet. I want that bull cock buried in me first." She stood, hiking her skirt to reveal her wet, dripping pussy, then climbed atop him.
Elena sank down slowly, her strong thighs flexing as she took every inch. "Fuck, it's stretching me perfectly," she gasped, riding him with powerful rolls of her hips. Sweat beaded on their skin; her ass slapped against him with each thrust. Maxim thrust up to meet her, the lab echoing with their panting and the slick sounds of her pussy gripping his hard cock. "You're so wet—dripping all over me," he managed between breaths.
She leaned forward, nails raking his chest. "Harder, student. Make me come on this monster." Their pace built to a frenzy until Elena cried out, her pussy clenching as she came, juices coating his cock. Maxim followed, groaning as he pumped thick cum deep inside her, both of them sweating and trembling in the afterglow.
Elena dismounted with a satisfied smile, already reaching for her clipboard. "Phase one complete. But the real tests begin tomorrow."
