During the day, Ririka works as an ordinary office lady. She heads to a man's apartment with a cool expression on her face. However, her mind is already filled with fantasies of deeply sucking her master's cock. Her body aches, but there's no helping it. Upon arriving at the apartment and being fitted with dog ears and a collar, she transforms into a dog that doesn't speak human words and receives lewd training. And when she finally gets to take his cock in her cheeks… just that alone makes her so overwhelmed that she ends up wetting herself...
