Ashley and Emily, 18 years old stepsisters, are at home texting on their phones, bored out of their minds. Suddenly, Emily's phone buzzes with an incoming message. She reads it aloud to Ashley, "Hey, want to have some fun?" Without a second thought, both girls decide to check out the mysterious invitation.
They follow the instructions and meet their older brother, Jack, in his room. He's lying on the bed, topless and clearly aroused. Ashley and Emily exchange nervous glances before Jack starts to undress them too.
As they stand there, naked except for their underwear, Jack suggests they play a game of truth or dare. Emily goes first and chooses truth. She has to ask Ashley a question she's always wanted to know. Ashley blushes and stutters when asked out on a date by her crush.
