The cute daughters of my remarried partner. And they're sisters who attend an all-girls school. Tonight, for the first time, we'll all sleep together in a river formation. The developing bodies of these new daughters stir up fantasies in me, their stepfather... When I wake up at dawn, I find that my stepsister's pajamas have come undone, and her defenseless body is right beside me! Losing all reason, I reach out to my stepsister despite my wife sleeping next to us. My stepsister moans softly as I touch her. Then, casually glancing at her sister, I see she's excited and writhing, having watched me with our stepsister. So, I turn my attention to her next... That's just the kind of loving stepfather I am...
