Student Affairs (1987)
In a dressing area, Veronica pulls down her top, frees her jugs from her bra, and plays "Tune In Tokyo" with her nips, much to the delight of the dude next to her.
Just a quick peek at her perfect palookas when she and her dude are caught with their pants down behind some paintings in a classroom. Actually, only he has his pants down. Darn.
