A bondage release in which Kitajima An, with her L-cup huge breasts, falls into the slavery training of cold-hearted sadists! A high-end auction club for members only, where only those with abnormal sexual desires gather. The person up for auction this time is a swimming instructor whose career as an athlete has been cut short… She is tied up with her hands behind her back and forced to deep throat! She is tied to a guillotine and hung by one leg while being trained with toys! Absolutely fixed creampie sex! She is tied to a slavery tool and trained to give blowjobs! She is tied up and impregnated in a 4P gangbang, becoming a human toilet! She overflows with a huge amount of sperm from her vagina and becomes a human slave!
