Sayaka (18 years old) stars as a high school girl who has done something wrong and is being punished quite severely. She first appears in her Japanese school uniform: beige blazer, short plaid skirt and baggy white socks. She is also wearing handcuffs chained to a dog collar!

The teacher (off camera) instructs her very sternly to dip one socked foot into a bucket of green gunge. Sayaka protests, but the teacher seems angry, so she submits and sticks her foot in, ruining one of her white socks.

Next the teacher tells her to take her socks off. Sayaka complains that it's embarassing, but again submits and goes barefoot. Then she's told to stick one foot into the slime. She complies and plunges one bare foot into the green goo, pulling it out to show it coated in the thick ooze.

The next part of her punishment is really messy: the whole bucket of green batter gunge is poured over Sayaka's head, covering her face and hair, and wrecking her blazer and skirt. But the next part gets even sexier as she is instructed to strip down to her bra and panties, then her hands are cuffed to the wall above her head, dungeon-style.

In this position, she is hit with a devastating custard cream pie to the face. Then she gets whipped cream pies smeared all down the scantily-clad front of her. And, as she takes another pie to the face followed by a chocolate syrup facial, we start to see that this naughty schoolgirl might have been naughty on purpose, she's enjoying her messy punishment!

Next we see young Sayaka hogtied: face down with her wrists and ankles chained behind her. In this helpless position, she happily submits to having her face pushed into another custard cream pie. She then takes one more hog-tied pied before getting the oatmeal treatment: her face is pushed into a large bowl of oatmeal porridge, then she is turned over so she is facing up and the oatmeal is poured over her face.

Next she is unchained and given a bucket of very thick chocolate batter to play with. She eagerly dunks her head in it and smears it on herself. Then she has whipped cream smeared in her face. Next she is given the whipped cream to coat herself. She smears it on her own face, then her body.

For messy foot fans, there are quite a few shots near the end of her bare feet when she is completely coated in goo.

Sayaka's dialogue is all in Japanese, but there isn't much speaking on her part.
