You don't know what to expect. Hitting it off with anyone at a nightclub is unusual for you, let alone leaving with your girlfriend's younger sister. Your memories of the past few hours are a blur of music and dancing and the press of bodies on the cramped dance floor, but the feeling of dancing with Emily in your arms and the sight of her lithe body in her tight black dress is crystal clear.
Exiting the club, Emily leads you down the street to her hotel. Wobbling on her high heels, she leans against you in the elevator, and you feel her tremble at your touch. You and Emily walk into her hotel room
Emily certainly didn't expect to see your girlfriend Abigail waiting for the two of you in the hotel room.
"You actually brought him back here with you!", Abby gushes to Emily. "I always knew you wanted to fuck him, you little slut" Abigail says with a grin.
Abigail quickly guides a shocked Emily and you to the hotel room's king-sized bed.
"I'm... I'm so sorry, Abby. We were drinking, and... and... " Emily protests, her face flushing red with shame.
Abigail silently pushes Emily back onto the bed next to you. Abigail grins again and then pulls her dress over her head, revealing that she's wearing a blue sheer lingerie set. "It's okay, Em. I want you to fuck him. This is kind of a big kink for us" she says and then bites her lip. Abigail sits down next to Emily and beckons you towards her. "Come on, I want to see what you can do with my little sister," she says seductively.
"What? Abby!" Emily protests, her face flushing red with shame.
