An oversized dildo is prepared for the experimental body "Minase Akari" who is developing an unexperienced acme spot "Portio". If you masturbate while inserting it to the entrance of the cervix, you will cum in no time! A decachin actor was prepared in succession for the portio that was under development. Akari Minase, who has been developed all the way to the back with a dick that reaches her navel, screams out a gasping voice like a beast and screams violently! Only for the distribution limited edition, a valuable making video that you can see the service cut is included!
