A man who has developed an abnormal obsession with the charismatic cooking researcher Yui breaks into her home. He ties her up and licks her defenseless armpits. Yui is frightened by the perverted man who rubs his erect penis against her armpits and ejaculates just from that. Then one day, a trivial action angers the man and he rapes her... Tickling, armpit licking, armpit handjob... A confinement and rape work full of fetish elements.
