The 4th installment of the popular series!! We invite J● on her way home from school to the studio, and when we ask her to call her close friends for a game project, we announce the real plan! Both of them blush and can't hide their confusion at the development they didn't know about...but this rotor that vibrates the clitoris with pinpoint accuracy will blow that away in an instant! If you tie up their arms and legs and spread them apart, you can see the pussies and anal holes of the young ladies! If you stuff the rotor into their pussies, the harmony of the vibrations and the young ladies' moans will reverberate! Unable to withstand the pleasure, they squirt and give birth to the rotor! A hard cock is inserted into the empty pussy, and they ejaculate with a pregnancy guarantee! The "sexuality" of the young ladies who didn't know anything about it will bloom!! And the staff who skipped work and the young ladies will have a secret, lovey-dovey sex...?
