Slacks to her knees first.

"Please, Kate," Sharon said. "Would you turn and touch the wall...pretend you're writing on the board while I undress you."

"It will be my pleasure," Kathryn told her former student. She laughed. "Don't worry, there's nothing on the board I'll be testing you on." Kathryn ran her eyes quickly up and down the young woman's figure, taking in her graceful height accented with a well-endowed chest, a slimmer version of her mother Petra.

Sharon had told Kathryn how she constantly watched Kathryn's butt whenever she wrote at the board. And Sharon had asked if she could rim Kathryn's ass, like Bridgett was doing with Courtney in the bigger party room downstairs.

Kathryn turned to face the wall of Sharon's attic bedroom and moved her hand quickly over the surface, pretending to write.

Sharon fell to her knees behind Kathryn. "Ms. Carlson," she said. "I've been watching your butt all year and I can't stand it any longer. Can I pull down your pants?" she asked, with a quaver in her voice.

"I suppose it will be all right, Sharon," Kathryn said. "You've already earned your A. What's on the board is for the benefit of the other students."

Sharon's face blushed red with embarrassed lust.

Puja's eyes crinkled with a smile. She had insisted that Kathryn precede her up the stairs to Sharon's room so Puja could watch Kate's butt. And so Kathryn could watch Sharon's butt.

Sharon rubbed her cheek across Kate's clothed buttocks. "Thank you SO much, Ms. Carlson," she said. She ran her hands over the curve of Kathryn's hips. She unclipped the side closure of Kathryn's tailored slacks. With a "z-zipp!" Kathryn's pants were around her knees.

Puja and Sandy looked at one another. They smiled and nodded at each other, seeing how things were going. They stepped to the side and removed their clothes.

Puja had her own plans for Kathryn. Kissing her earlier had been a delicious appetizer, but Puja was determined to make Kathryn squirt and drink her wine of joy.

Sandy was putting together her own plans for their hostess' daughter Sharon. Sharon's youth and eagerness made her a delightful kissing partner, even if the taller girl had to dip her head a bit to kiss Sandy.

Sharon breathed in the warm fragrance of Kathryn's body released as her pants fell, just as Kathryn had earlier when she was undressing Sharon. "Oh god you smell so good," Sharon gushed. She kissed each of Kathryn's buttocks on the skin below her silky panties.

"Now Sharon," Kathryn teased. "Please don't distract the other students. I'm not finished writing. If you want to be helpful, please take my slacks all the way off."

"Yes Ms. Carlson," Sharon said quickly. She eased Kathryn's slacks off, one foot at a time as Kathryn stepped out of them.

"There," Kathryn said, dusting her hands after pretending to put down her chalk. Whiteboards were coming next year. "That should do for a summary." A twinkle came in her eye. "Sharon, before you take off my panties, would you read it out for the class?"

Sharon looked up at the blank wall of her bedroom, then at her former teacher, down to top and panties.

"Start here, Sharon, where it says..." Kathryn prompted Sharon with a suggestive phrase.
