Yes she does.

Emma and yourself dress as fast as you can but to no avail. Katherine opens the car door with a shocked look on her face. You’ve only managed to put on your boxers, you had no chance. You look over at Emma, her face is flushed red with embarrassment.

You begin to think of all the possibilities. You think of Katherine asking for a threesome, you imagine doing things you never thought were possible. You've read so much erotic literature that it's gone to your head.

SLAP

Katherine whacks you across the face, with a palm full of rage. That sure brought you back to reality. You look into her eyes and you see they are filled with hurt and pain. ‘What have I done. Is there anyway to save this night, it was supposed to be wonderful.’ You think to yourself

"How could you, you JERK!" Katherine yells at the top of her lungs, making a big scene in the parking lot. You are scared and filled with shame.

"This night was supposed to be special," her tone of voice slowly changing from angry to sad, as she starts sobbing. You feel stupid for messing up a night with so much promise.

"I can explain..." you continue before you're interrupted.

"I don't even want to hear anymore from you," Katherine sobs with tears flowing down her cheeks. You can't help but feel guilty. You let Emma seduce you, you can’t believe how out of control you were. That Emma sure knew how to excite a man, though.

"How could you do this to me, Emma. You're my sister," Katherine continues with sad eyes. Emma just looks down in shame, only wearing her matching bra and panties.

"You insensitive jerk!' Katherine continues her rant, sobbing. She just stands there crying frantically. You look over at Emma and she whispers rather annoyed, “don’t worry, she’ll get over it.” Wow, Emma wasn’t too helpful, now was she? Emma smiles at you and seductively continues with pleading eyes, “me and you can have fun tonight, I’ll take her home, then I’ll take you to this one place I love, it’s great.”

“Forget that.” Katherine sobs, overhearing Emma, while desperately looking into your eyes. “I know my sister is a tease and…” she continues but suddenly runs away towards the curb, sitting down.
“Lets just leave her here, I’ll call a cab for her.” Emma comments. You look into Emma’s deep blue eyes and they soften as she smiles. You believe that’s she’s a good person, deep inside. You wouldn’t mind getting to know her more. You still wonder if you should go comfort Katherine.

You contemplate your situation. What should you do? On one hand you have an extremely hot girl willing to party all night with you, on the other a sobbing girl, who’s heart you’ve broken, with a relationship that’ll be hard to mend. You have more in common with Katherine than Emma and you can’t help but wonder how fun the dance will be. Emma is a great lay and there may be more to her than meets the eye.
