The characters
Your name is Steve, a twenty-two-year-old college student. Your newly single as your G/F was caught cheating on you with her own brother.

Tiffany, your youngest sister, is turning eighteen years old today. You and your two others sisters (Amanda (nineteen)) and Miley (twenty)) have traveled home from college to celebrate.

Your parents have left to get some party supplies and shouldn't be home for hours. Tiffany wants to play a game, but seeing as it's just the four of you, and your family has no board games, the options are spin the bottle (not a game they are thrilled about), truth or dare (peaks all their interest), or hide and seek (which has some interest also).

Since it's Tiff's birthday, she picks truth or dare. And since it's her birthday, she goes first.

Who does she pick?

(before we move on, here's what the characters are wearing from what you can see.)
Tiff: short pink skirt that says "sexy" on the ass. White shirt.
Amanda: Shorts, black shirt.
Miley: A backless summer dress. no bra (at least no bra straps)
you: Jeans, OSU shirt (your college), boxers.
