This is a special facility that forcibly turns newhalfs into masochistic submissives. The test subject, Mihamaru, is surrounded by two nymphomaniac researchers... As they strip off Mihamaru's panties, the erect penile clitoris is mercilessly pounded until forced ejaculation! The nymphomaniacs delight in the cute reactions of Mihamaru, engaging in intense piston sex in a crab-legged riding position, and tormenting the anal vagina with vibrator expansion for pleasure...! Repeatedly subjected to the 'research' by the nymphomaniacs, Mihamaru falls completely into a masochistic female... Enjoying themselves while being triple-teamed with a penile band, they climax explosively through their anal holes...!
