Gungemistressuk and Backtomrsb have been caught smoking behind the bike sheds at school. The naughty girls are summoned to the gunge pit to receive their punishment!

Bent over, Gungemasteruk pulls up their skirts and designates one a "Cum Slut" the other "Suck cock," foretelling their ultimate destiny.

Tied to chairs, he exposes their breasts and covers them in warm, thick gunge, before degrading the naughty girls by dunking their heads in buckets of slime.

With their punishment complete, it's time for some pleasure, as Backtomrsb is rewarded with a vibrator to pleasure herself. As she plays with her pussy he continues to cover her in gunge, resulting in a climatic orgasm.

Gungemistressuk is then sat in an empty box, with a vibrator in her pussy, as Backtomrsb scoops up the cold slime from the gunge pit, as it's poured over Gungemistressuk. As the box begins to fill Gungemistressuk is brought to climax.

With a happy ending for both girls, it's Master's turn, as the girls take it in turns to suck his cock and massage his balls--before he cums in a shot glass, which Backtomrsb hastily gobbles down, like the good Cum Slut she is.
