Secret Hot Tub Sex with My Step-Sister's BFF. I was sitting in the hot tub after a long day at work when my Step-Sister's best friend Emma popped in, Emma asks if she can join me after I tell her no she still just jumps in with me. I blink my eye and she is taking all her clothes off and starts to tease me with her feet under the water. I can not believe my Step-Sister's best friend is coming on to me, I always wanted to fuck her she is the hottest one of my step-sister's friends. I pump her tight pussy with my big dick right outside on the pool deck, hopefully, my step-sister or parents don't walk upon us. I thank Emma for the good pussy with a nice big facial, I hope I can fuck her again..
