Very embarrassingly.

Berry's blush only grew as she heard her classmates whispering all around her. It was clear that not a single one of them was listening to the teacher, and to make matters worse, a tall, lean boy with messy black hair picked up his bag, moving to beside her on the counter as people around giggled. He wasted no time in laying a hand on her ass, pushing her own out the way as Berry was powerless to stop him from using her like a stress ball, kneading and stretching her tights clad ass, but then it got worse. She felt his hand slide along her ass, and then her tights moving away from rear slightly, as her eyes widened and there was a quiet "Riiiiiiiiiiiiiiip-" as a large hole was created, exposing her ass fully, while leaving the rest of her tights intact. The boy's hand returned, and Berry's blush grew and grew as he felt up her now completely exposed posterior.

The teacher finished speaking, ending her explanation of the lesson with a simple: "Now get into pairs, and get to cooking! I'll be back in about 10 minutes, I just need to talk with another teacher" With that, the teacher stepped from the classroom, unknowingly leaving the poor berry to fend for herself.

Berry, of course, ended up with the dark haired boy feeling her up, and was **** to try and flip through her recipe book to find a recipe for "Cream Buns." The boy suddenly let go of her ass, and Berry let out a sigh of relief as she watched him go over to his bag and kneel down. The relief immediately dropped and was replaced with fear and dread as she watched him pull out a long, black, human sized cat tail, with a daunting shape on the end of it....

"I-is th-that-" Berry stuttered, slowly backing up before she found her back colliding with someone behind her, only to feel a pair of hands on her shoulder that quickly swivelled her around. She was met face to face with Brittany Jones, the blonde haired head cheerleader of the school, with a smug look on her face. "Heya Berr-Berr!" She cooed teasingly, "How's my little kitten's day going?" With this, Berry began to feel something press between her rear cheeks, and try to wiggle out, but Brittany held her still.

"P-please d-don't..." Berry said, almost inaudibly, the crimson glow of her face making her embarrassment clear to any watchers on. The cheerleader only smirked in response, as Berry put a hand over her mouth in horror, and to silence her cries of pain, as something entered her ass, stretching it wide as fur tickled the skin around her back entrance. "There we go B," Brittany said, a glowing smile on her face as she let go of Berry's shoulders. "Buuuuut, I think we're missing a few bits." She snapped her fingers over her shoulder as another cheerleader ran up behind her, placing a pair of items in her hand as Berry gulped. A collar and a pair of cat ears. This was going to be a long lesson.
