Fun for the Whole Step

This is like a dream come true! I get to fuck my stepmom AND stepsister at the same time!! It's obvious that sis is nervous, she thought since stepmom caught us experimenting and having sex that she was in trouble.. But I told her about the fun stepmom and I had and I think she actually got a bit jealous! I had to explain to her that the only reason stepmom and I messed around was because of how turned on she got from watching us!
