A woman in her 20s is being fucked by a monster with a huge trunk, an ancient dungeon with a woman, depraved women bent over, and schoolgirls. Her vagina is spread to the maximum. She can wear high white collar and cuffs. There may be a school notebook with her name on it. The laboratory is incomprehensible place where an ancient dungeon with a worm extender lies and is fucked by an experiment with vagina, a vaginal pump in place, and an experiment with sex machine experiment. Laboratory in place where there are old women in aprons and grandmothers wearing rubber pumps on their bodies. A depraved woman bent over, her face contorted as she's being fucked by the monster's penis. She can wear high white collar and collared shirt or granny clothes like lab coat or sweater vest. The latex bodysuit may be worn under the lab coat or shirt for extra protection during sex experiments involving vaginal pumps or other sexual devices that require more protection than just latex gloves. The woman may also be wearing protective gear such as rubber gloves to prevent contamination from any fluids that may leak out of the vagina during penetration.
