Horny stepdaughter's anger after unexpected encounter

In a typical American household, a father and his two stepdaughters share a close relationship. The eldest, a gorgeous girl with an insatiable appetite for pleasure, often teases her dad, making him blush. One evening, after a night out, she playfully flirts with him, leading to a heated encounter that leaves her father's friend on the couch with a front-row view. Upon discovering this, the youngest stepdaughter is understandably upset, and her anger only grows when she discovers that her sister wasn't even her dad's biological daughter. This revelation leads to a heated confrontation, but the father's friend intervenes, revealing that he too has been watching and enjoying the show. The scene ends with the girls venting their anger and frustration, but the tension in the air is palpable.
