I arrived home from school a Thursday evening and mum called me from the kitchen.“Briana, Mrs Johnson called. She wants to know if you can go around... and help her with a few things.”I smiled to myself. I bet she does.I finished my homework and set out for the Johnson house. I knew Kelly had gone away for the weekend. I bet her mum sent her there so we could have another threesome. I didn’t mind, I like the last time.I arrived outside the Johnson house and looked around to see if anyone was. I could feel it happening, my orgasm was building.

She helped me by propping her left knee over my hip, leaving her pussy easily accessible to my fingers.She was so hot and so wet with her own juices, I wondered if it was time to change tactics. However when.
