Really guys it's disappointing that no one here seems to understand how this chair works. Having sex with two women does not mean having intercourse with two vaginas at the exact same time and is actually physically impossible since you only have one penis. Having sex with multiple partners simply means engaging in sexual ACTS with multiple people at the same time. The purpose of the chair is to have one woman on top of it with the prince standing in footrests pounding away while lady number two kneels on bottom platform and licks his balls or eats his ass. Now here is the other option, girl one kneels on bottom platform, prince kneels on lower cushion of bottom platform and screws girl 1 doggie style or has her face him and suck him off while he is eating out girl two who is at face level on top platform. Mystery solved, hope this helps satisfy the curiosity of many.
