Koko, a cross-dressing cosplayer with a beautiful face, curves, and fair skin, is known for captivating men. In the first part, she is called to a fake cosplay meeting by a middle-aged man claiming to be involved in doujinshi. In a multi-tenant building, she is initially kissed and has her penis devoured. However, she soon becomes aroused, performing deepthroat fellatio and analingus on the man. She is also penetrated and brought to orgasm repeatedly. The second part, filmed a week later, shows a hotel rendezvous. Both Koko and the man are even more intense than before, eagerly seeking each other's penises and anuses. During foreplay, they engage in 69, with simultaneous oral ejaculation and semen consumption. The subsequent anal sex involves various positions, including reverse anal, with Koko experiencing rectal orgasms and convulsions. The session concludes with a large amount of semen ejaculated into her anus, which is covered in intestinal and fecal fluids. Unexpectedly, two of the man's friends from a cruising spot join, initiating an impromptu foursome. Amidst the scent of sweat and semen, Koko masturbates, releasing a significant amount of semen, which one of the participants cleans up with fellatio. This intensifies the men's desires, leading to vigorous anal penetration that brings Koko to orgasm repeatedly, while they also ejaculate onto her penis and into her anus.
