The arrow ends up pointing towards a girl named Alice. Alice went to highschool with you and Ricky, and she always was known as the "hot bitch", even by her own self admittance. She wasn't mean however. Far from it actually. However she was practically a nymphomaniac back then and had a reputation for being more than just flirty with anyone who would listen to her and was even halfway good looking.
But the one thing really going for her was her abundance of natural beauty and coupled with her shamless approach to "socializing", she became a pretty popular girl amongst the boys, unsurprisingly. The girls not so much and thus where her nickname came from. Though she never sought after taken boys, but she wouldn't deny their advances either.
She did tone it down however after highschool, but she still is wearing her same style from back then that intentionally leaves very little to the imagination. Her large chest still is displayed proudly within the limited confines of her deep, v-neck crop top. Her short shorts are not going to do it for you as you doubt that they could even cover up your boxers. Her shoes also were much smaller than your feet as well.
"Um... I guess your top?" You say, like its a question. Alice just shrugs and pulls off not only her top, but her bra too and hands both to you. She then waits for you to remove your shirt, not even bothering to cover up herself, and when you hand it to her, she just puts the sleeves on and doesn't bother to button up anything more than a single middle button.she doesn't even put on your undershirt.
You look down at the bra and top, then sigh and put them on, one at a time, and as best you can having no experience with wearing either of them. You manage to get her bra on thanks to the help of Quinn who is standing next to you. She just gave you some advice and helped you clasp it together. You then pulled her top over your head and arms, bairly managing to squeeze into it.
You both feel and likely look ridiculous, but at least everyone will be joining you soon enough. You are about to spin the wheel again, when suddenly you hear Alice gasp. You look up to see that Alice's chest is now remarkably flat, and larger, fitting into your shirt much better too.
It is then you feel your chest being pulled downwards as your upper body shrinks, yet a pair of huge tits pop out of your chest, filling out the 32GG cup sized bra completely. Now from the underside of your chin, down to your waist, and then everything between your shoulders, has become identical to what Alice has just lost. Then it clicks. She didn't lose her breasts, you two have almost certainly just swapped chests. These are her boobs. It's no wonder they fit her top and bra so perfectly.
You turn to look at a deviously grinning Ricky. "Ricky, what the hell just happened?" You ask in a confused tone. However everyone just looks at you with wide eyes. Then you hear your own voice speak to you. "Hey, you have my voice now too!" Says a surprised Alice. She then looks at Ricky with an oddly excited expression. "Wow, is this what happens at these parties? This is so cool! I sound so manly right now!"
"Ricky, what is going on here?" You ask, noticing how you now speak casually using Alice's seductive, breathy voice.
"Exactly how it looks. Durring this party, you will swap body parts depending on who and what clothing item, you select, or have taken from you." Explains Ricky, who spins the arrow again to pick the person who is up next.
