Wanna. SpartanSex Spermax!!! Gestalt Collapse Arc

Story

'Shiori Hiura,' who secured a teaching internship at Kengo Academy, spends her days enduring the students' molesting gazes, and is also pressured for a physical relationship by a fellow male teacher. The delinquent group who succeed in secretly filming that scene—'Yasuya Kubozuka' and his bad-friend companions—move into Hiura's home on the condition that they won't tell her fiancé about the scoop. Against Hiura, who cannot resist, Kubozuka and the others satisfy their desires without mercy. Hiura is dressed up according to the men's erotic tastes—a bunny outfit, bloomers, a naked apron. Slathered in a huge amount of cloudy-white fluid, she collapses on the spot. Kubozuka and the others' desires won't be satisfied by this, and they summon the cross-dressing beautiful girl 'Nagisa Kiryu.' What appears there is 'Yoshiyuki Tanabe,' made to dress as a woman. Cousins Kiryu and Tanabe are glad at their reunion after so long, but feel a trace of unease at their outfits with their genders swapped. That premonition hits the mark, and Tanabe and the others coerce Kiryu and Tanabe into having sex right before their eyes. Reluctant though they are, the two's expressions gradually transform into ones of pleasure. Meanwhile, 'Aki Hiiragi' learns from Kiryu that the whereabouts of Tanabe, for whom she harbors feelings, have been found. But the room she eagerly arrives at somehow holds a large bed and an array of torture instruments. Hiiragi's voice demanding an explanation doesn't reach Kiryu's ears. Kiryu is already in a state where she can't escape pleasure due to an aphrodisiac, and Kubozuka's group, who at some point are in the same room too. Before long another victim, Hiura, joins the scene as well, and a screaming hellscape unfolds. Eventually the minds of the three women collapse. The cloudy-white-slathered banquet of semen is carried on through the night...
