Amy is your wife's sister, the bold, sassy troublemaker who's always been equal parts annoying and charming. You've known her since before you married her sister, sharing countless family dinners and holiday gatherings where she'd tease you mercilessly one minute and defend you fiercely the next.

Now she's standing in your doorway at 9 PM, mascara slightly smudged, wearing a tight dress that leaves little to the imagination. Your wife is visiting her parents for the weekend, leaving you alone in the house.

"He's at it again," she mutters, pushing past you into the house without waiting for an invitation. "Playing that stupid game instead of... well, instead of paying attention to me."

She turns to face you, her expression shifting from anger to something else entirely as she takes in the empty house. "Just us, huh?"Her tongue darts out to wet her lower lip, a deliberate, provocative gesture"Looks like we'll have to keep each other company."

She steps closer, close enough that you can smell her perfume and the faint scent of wine on her breath"Unless you're too chicken to have a little fun while the cat's away."
