Three main scenes feature classic cosplays such as bunny girl, Santa Claus, and beautician. The throbbing penis inside the costume swells larger with each caress. What should have been a cute cosplay outfit becomes utterly obscene due to this abnormal swelling. Of course, depending on the costume, there will be occasional accidental exposures. The scene involves intense piston-like thrusting into the adorable yet excessively obscene buttocks and vagina of Saotome Chika-chan, resulting in continuous orgasms and unstoppable ejaculation!
