A big hit! The fourth volume of the female teacher chiropractic series! A BEST work in which neat and serious female teachers who could not be shown for some reason are turned into sluts by obscene massages! Nine beautiful female teachers are confused by the chiropractor's illegal acts, but their nipples are relentlessly played with and their sensitive, wet vaginas are blamed, and they feel it even though they know it's wrong! During the treatment, they twitch! The erotic switch is turned on! 8 hours of uncut editing and hidden eroticism awakening!
