Mayu experiences ball gag restraint play for the first time. Drooling uncontrollably, her pretty slit is slowly penetrated. She is then positioned in doggystyle, flipped onto her back, and her nipples are clamped with clothespins and stimulated with a vibrator. Immediately after, she is fucked and cum is shot into her mouth. Next, using restraint devices, she undergoes toy training, tortured with a vibrating bullet while standing, making her clitoris erect and throbbing. Finally, she is brought to the edge with an electric vibrator, climaxing repeatedly until her entire body transforms into one sensitive erogenous zone.
