[RAYMON] Hataraki Ari no Riron (Nyotaika Ouji to Tatasare Hime) [=White Symphony=]

Oikawa and his fellow test subjects are caged inside the isolated facilities of a Super Human Research Laboratory, and after days without relief, the muscular stud and his horny cohorts take their frustrations out on the busty Azusa and Yumiko. When scientists running a twisted 'worker ant' experiment flood the facility with gas, Oikawa wakes to find himself saddled with a soft, curvy woman's body—and an overweight researcher wastes no time stealing his new virginity, pounding him until reluctant pleasure overtakes the gender-swapped prisoner. The tables turn one last time when the girls strap on enormous dildos, with Azusa and Yumiko declaring they'll claim his front and back at once in a merciless reverse gang rape.
