The first nude festival for 15 members of the SOD group! Huge piercings pierce both nipples! A perverted masochist woman wears perverted straps and accessories like key chains, tugging on her piercings until they almost tear off, and moans! She dances with her piercings in a shameful, crab-legged dance at a family restaurant, and then trains her nipples at home, using various attachments to play with and train them! Public training with electric current torture on nipple piercings... bukkake creampie in front of the audience, ahegao face, and double peace sign!
