Lily Krystal (wearing a school girl outfit) has decided to punish Professor G for assigning her detention while he takes a nap. In a previous clip Lily has already bare foot trampled him until he went out. Now in this clip Lily makes the professor lick her black, filthy soles clean. She verbally humiliates him as his tongue is black from the filthy he licks from the bottom of her feet. Once he has completed the assignment Lily Krystal orders him away.
