Sitting behind him was Kari. Her eyes were glued to the movie, and as Alex looked down, her hand was glued to her crotch. But that wasn't the source o... the sound. He looked beyond her and back at his teacher, who was sitting in the back of the room. She had a hand in her pussy! She was bucking her hips and moaning loudly. Alex looked around the room to see if anyone else had seen this, and Kari stopped him. "What are you looking at?" she asked. He pointed. They both stared. Miss Anderson came. She then turns around and sits in his lap, her back to him and presses her ass hard into him as her hand slides to your inner thigh and up to about 2 inches from your slit. You look as he plays with her tits and her nipples harden as her legs are spread and you look down at her shaved pussy. At the end of the song she picks up her clothes and asks if she could join us after her next dance on stage. Before John can answer you tell her she is welcome to and she bends over and kisses you lightly. This was the second or third time she had said that. She was either too embarassed to voice what she wanted to try, or she had something so outlandish in mind that she was trying to ease us into it. Or most likely a mix of the two. I kissed the flatmate’s forehead softly and she sighed.“You know, she and I have done a lot of, uh, kinky stuff together. Not just the stuff you’ve seen today, but uh, other stuff too.”The flatmate nodded, but avoided making eye contact. Her hand continued to stroke. Fuck me again...fuck me deep...I love your cock in me."With that she started shaking and mumbling and pushing back. I looked down and saw she was also rubbing her clit as we fucked. She screamed out one last time, "Yes. Yes, now... I'm cumming Oh My God!"She stopped moving and stayed still, my cock still buried inside her. She slowly moved forward and stood and faced me. She almost had a dazed look on her face. I chalked that up to probably a combination of the pot we smoked ealrier, the 3 or 4.
