Cut to 30 minutes later

“Ohhhhhhhhhhh!!!!!” Was the noise both Elizabeth and the end-of-lunch bell chimed. This was the 3rd orgasm for Elizabeth in the 30 minute break. Miss M, or Mistress M as Elizabeth was now calling her, had the 18 year old legs curled up in the air, lying on across the teachers desk, bare vase body for any passerby to see, folding her torso over in orgasmic bliss. Elizabeth’s pussy was dowsed in the spit of Mistress M… or you could say Mistress M was filthy with the pussy goop of Elizabeth.

But lunch was over, Elizabeth had to go to her next class. So, playtime had to come to an end.

“But… but… Mistress… please?” she begged.

Mistress M stuck her thumb in the cunt of Elizabeth and wiggled it around. Her middle finger, out of instinct, found the outer edge of Elizabeth’s butt and started to tickle that star shaped hole. Mistress M just shook her head.

“There’s always tomorrow. Besides, you have swim team to head to after school right?”

Elizabeth nodded.

“Don’t you want to see all those pretty naked girls and come tell me about them tomorrow?”

Elizabeth nodded again.

Mistress M picked up Elizabeth’s underwear, put it in her desk, then put her own cloths back on. “You want me to be your mistress?” Elizabeth nodded a third time. “Then I’m keeping these. If you’re caught without your underwear, then you’ll have to deal with me. Again.”

Miss M didn’t know if this was a threat or a demand. Elizabeth could think that she had to get caught, or she could think that things would be worse, much worse, if someone found she didn’t have underwear on. But Miss M now did know that Elizabeth did have a preference for the women of the school.
