Isabel Triznine is called into an empty classroom and forced to stand before a greasy, obese professor.
The professor's thick fingers lift up her uniform skirt, push aside her panties, and part her labia. He grabs the girl's arms as she resists, throws her down onto the desk that serves as her bed, and covers her with his sweaty, massive body.
The professor's short, thick penis forcibly pries open her virgin vagina, rubbing against her narrow vaginal walls and gouging her cervix.
As blood and love juices mix, the professor takes a video of their insertion on his smartphone.
"Now you're mine."
Isabel cries in pain and humiliation, but her body is forced to climax, and she convulses as he cums inside her.
Late at night, Isabel is collared in a park and made to crawl on all fours. At the professor's command, she places her hands against a tree and his thick penis thrusts into her from behind. Her breasts, exposed to the cold night air, are grabbed by the professor, who twists her nipples as he thrusts violently into her.
He rotates his penis deep inside her vagina, relentlessly probing her G-spot, causing her to moan like a dog and squirt on the floor. The professor thrusts his fingers into her anus, double-penetrating her, and repeatedly ejaculates inside her while slapping her buttocks.
Threatened with the photos, Isabel is unable to resist, and her spirit is gradually broken by the nightly pet play.
A few months later, in a suite at a luxury love hotel, Isabel's belly has swelled with pregnancy, and white breast milk drips from her breasts, now over E-cup.
She straddles the professor in cowgirl position, rocking her hips and scraping out pre-cum from where they are joined. Her sensitive vagina clamps down on his penis, and her uterus trembles along with the fetus.
As the professor massages her breasts with both hands and sucks her nipples, she squirts milk and climaxes with an ahegao face. He holds her thighs up in the missionary position, thrusting deeply into her, bringing her to orgasm repeatedly.
Her once brave expression had vanished, and she had turned into a sex slave, with a lewd smile on her face, begging,
"Please pour more of your baby seed into me, Professor ♡."
