Shinobu Kasagi returns in the second installment of the controversial series about trapping women in a trap and training them as female dogs. Shinobu, an older sister who lost her parents and lives with her younger brother, a high school student, is depicted being blackmailed and unwillingly trained by her brother's seniors. The video features various scenes including yard cleaning with a remote-controlled vibrator, shopping in sailor uniforms wearing diapers and a mouth gag, public stripping in front of her brother, pissing like a dog, eating chewed dog food, hands-free blowjob, and sex with stockings pulled over her face. Through unprecedented harsh experiences, Shinobu confronts shocking new sensations—wearing stockings, using a mouth gag, and eating dog food—revealing a side of her no one has ever seen before.
