Rachel and her step-daughter Ember have been out by the pool sunning topless. Rachel sent her in to get drinks. Her boyfriend was waiting for her. He wanted to have some fun. He tied her to the staircase and invited a friend over to help. They had played a pool game with her and she lost so it was her turn to pay. They had two vibrators and they her to cum. Rachel came inside and saw what was going on. Her step-daughter asked her to help but Rachel pulled her panties down instead. They made her scream out in orgasmic pleasure. She will never bet again.
