A girl loves him so much that after school, in an empty classroom, she caresses the desk of the boy she has a crush on.
She licks the desk and chair all over, and simulates a kiss with the boy.
She finds his personal belongings and licks them all over, then places them against her crotch and begins masturbating.
She can't control herself anymore, and finally starts rubbing her crotch against the chair or desk, and engaging in air sex...
She doesn't want anyone to see her in such an embarrassing state, she can't show them... but she can't stop...!
A surreal image of masturbation.

The image of a girl having air creampie sex while thinking about the raw cock of the boy she likes... it might actually be erotic...!! (Karin, who was caught in such an embarrassing state, made a desperate confession and was able to have creampie sex with a real cock...! Good for her!)
