Saori, a popular writer, is busy with her writing, and because of her voluptuous breasts, she often suffers from stiff shoulders, so she often uses a visiting masseuse. Recently, she has been receiving massages from Jojima, who appears to be a skilled masseuse, but is actually a professional in the field, skillfully stimulating sexual pressure points to seduce women. Saori, whose sexual arousal is stimulated by Jojima's massage, is deceived by his eloquent words and becomes addicted to anal pleasure.
