Gungemistressuk has been caught graffitiing at school, and is sent to the Headmaster's office for a detention. But she's in a bratty mood, and when the Headmaster doles out her punishment of a good flogging with the whip, she bends over to accidentally reveal a jewel in her body; which is against school dress code rules.

Having been whipped the argumentative girl is told to get on her knees. Unhappy with the lack of respect being shown the Headmaster instructs her to suck his cock, before removing her crotchless knickers to expose her bald pussy. At this point the Headmaster instructs her to fiddle with herself, before he finds a bucket of white gunge, and begins to slowly pour it over her head.

She's disgusted at being covered in the warm goo, so the Headmaster instructs her to get on her knees, with her head over the slime. He grabs her pig tails and thrusts her bratty face all the way into the bucket. Unable to wriggle free she is dunked repeatedly in the bucket, until she finally admits that she's beginning to enjoy her detention.

As a reward for being such an obedient pupil the Headmaster offers her the chance to have some fun with her vibrator. Gungemistressuk moans with pleasure as she's covered in gunge, bringing herself to climax not once, but twice, in very quick succession.

Clearly recognising this isn't any normal kind of school detention, the Headmaster instructs her to roll over onto all fours. Checking her butt plug is still firmly in place, he then proceeds to enter her from behind, much to her squeals of discomfort having recently cum so hard.

Finally, with her mouth wide open she wanks off the Headmaster, straight onto her face, much to the bratty schoolgirl's disgust. Will Gungemistressuk be better behaved in the future? We'll just have to wait and see!
