Sweet nerd Trillium is left home alone with her stepsister Niki. These two are serious opposites. Trillium is pretty conservative, whereas Niki loves to show off her sensational body and embraces her sexuality and they don't always get along. Trillium has a lot of studying to do, but Niki has definitely got other plans. She brings Michael back to the house for some action, but as quiet as they try to be, Trillium is soon on to them. She finds herself watching her stepsister sucking him with her succulent lips, and it doesn't take much for her to be persuaded to join in the fun. This geeky young thing is soon enjoying every inch of him, in both her wet mouth and wetter pussy.
