Although all the students were over 18 they has to wear girly school uniforms. But not all uniforms were the same.
There were two types of students. The model students were girls and sissies who were learning to serve to one day be a housekeeper or head of service. The slutty students were all sissies condemned to a life of servitude and humiliation, which is why their uniforms were different. Their skirts were shorter. They had to wear their hair in pigtails, ponytail or a bun to make it easier to grab them for punishment or to fuck them. To facilitate ass-fucking they could not wear underwear or if they did they had to have openings to allow penetration. To distinguish them from their classmates they had to wear red stockings or socks and red shoes.
In class the seats were also different. The seats of those who wore red shoes had dildos of different sizes so that they would always remember their function in the world: be a hole to be fucked.
Piggy had been lucky and they had sat her on a bench with a dildo that was quite small and not very long. To the left of her they sat the maid Virginia, who as a model student had her cock free, more than double the sow´s in length and thickness. To the right of her was Lena, a very advanced student who loved to harass Piggy and make her lick her pussy and ass at recess.
Mrs. Chus was giving a shoe and foot licking class when Lena began to massage Piglet's testicles and glans, and she moaned slightly and looked at the maid Lena without understanding. While she was taking notes, Lena continued rubbing the slave's parts, until a moan caught the teacher's attention.
--What's going on over there?
--Nothing, Madam Professor-- the slave responded quickly.
--She's lubricating-- Lena said, pointing to some drops on the floor that were the result of touching her partner.
"But, teacher," said Piggy, but she did not continue because Lena handed her a paper in which she said: "If you tell something, I say that you have put your hand to me." Let's see what she do to you?
--But lady what? --asked the teacher.
--Nothing¬-- answered the slave, looking down at her desk.
--I think she was moving her ass to pleasure herself¬-- Lena commented in a good girl's voice.
--Yes, they already told me that you like to have things stuffed there, slut, well we are going to give you pleasure. Come here!
The slave knew that she couldn't talk back to the teacher, so she got up, walked past Lena, who pinched her ass, and walked out into the hallway with her eyes downcast.
--What do you prefer first, fatty, pain or pleasure? --asked the teacher.
--Miss, can I lick your shoes? --answered the slave trying to appear very submissive.
--Okay, but remind me to double your punishment for not responding.
--Yes, Mrs. Chus--responded the fat student, kneeling down and putting her tongue close to the teacher's black shoes.
When she did so, the plaid miniskirt exposed a large part of her ass and the red panties with an opening that she was wearing. Those underwear were allowed. The display of her ass caused some of the students to laugh and Lena shouted the nickname they had given her during recess: "She's the fat slut" and they all laughed heartily, including the teacher...
Meanwhile the slave cleaned the edge of her shoes, near her stockings, without even touching them. The teacher liked this very much, and she told her that she could lick her shoes whenever she crossed paths with her, to which the sucker replied that many thanks from her.
As soon as she finished licking, the fat girl stood on the punishment bench without taking off her shoes and the teacher said: "What do you want, for me to spank your shoes soles?", which again caused the entire class to laugh. The slave took off her ballet flats and was left with her red superfine lycra socks.
--Should I take them off too?
--No, the punishment will end when they break.
The fat student then placed herself on the punishment bench, leaving her ass for punishment and the soles of her feet at the perfect height for the spanking.
