A female tutor is attacked by some naughty boys with water guns on her way to work. She has no choice but to teach the students without a bra, and the students get turned on by her huge breasts. The naughty boys then mix an aphrodisiac into her water and splash it all over her. The horny teacher Yoshikawa ends up sucking the student's hard cock and is violated by the naughty boys, but the woman's body reacts to the aphrodisiac and can't be stopped.
