Nico, a "cross-dressing boy" who claims her anus is her ultimate erogenous zone, is the subject of this fetish and maniacal video that closely examines her buttocks, pushing them to their limits and subjecting them to intense pleasure. Nico's healthy, athletic body is fully erect from the moment of the interview. Even a simple sensitivity check sends her into a climax. With her sensitivity switch turned on, Nico's anus opens wide with the stimulation of a vaginal vibrator, and she takes in a monstrously sized dildo, reaching another climax. She enjoys the sensation of foreign objects like an extra-large zucchini and a thick carrot, and is surprised by her first experience with a 60cm long plug, yet still convulses in orgasm. Her rectum is examined with a steel mouth opener, and she experiences a hyperventilating orgasm with a gigantic 10cm diameter dildo. Finally, she is subjected to anal fisting and anal sex by two men, reaching multiple orgasms.
