Mom has been really having a hard time lately with her step-daughter and her boyfriend. They argue all the time, Mom thinks she doesn't know how to tell them apart and that they're not ready for sex. So one day she takes her little stepsisters into the bathroom and starts fondling their new boyfriend's big strong hands. After a few minutes of touching and whispering "what are you doing, honey? ", the horny step-daughter tells her mother in an embarrassed tone, "I thought you'd never ask... I wasn't expecting you to give me a hand job, but it just felt so good"..
