Go for the skinny one

You pass your can to your left hand, before placing your right hand on the skinny one's thigh. You lean towards her with a smile, making it clear which one you're going for. She smiles back as your hand strokes her inner thigh slowly. Thankfully the fat one gets the point, moving away from you both and leaving the room. With that, you go for her.

You lean in closely, before pressing your mouth against hers, your tongues sticking into her mouth, lapping around at the inside as you taste the beer she's been drinking. She goes for you voraciously like a predator, grabbing you and pulling you in closely as her tongue explores her mouth, sticking it deep down your throat and swirling it around. You put your can down, unbuttoning her shirt slightly and reaching inside, popping it under her bra and grabbing her tit, squeezing it firmly as you roll her small tit around in your hand, gently rubbing the nipple against the palm of your hand as you squeeze it firmly. You continue groping her chest as you make out with her, your eyes closed and your tongues lapping against each other as the taste of your cider and her beer combine in your mouths.

She pulls back for just a second, hopefully to go for your junk or get a bit less dressed. Unfortunately, that's not it. She immediately draws her head back, and begins to throw up. You desperately squeeze out from under her as she throws up on the floor next to you, beginning to puke in the cover. Wiping off what little puke got on you, you cautiously move away from them. Well, that didn't go well. With that, you move out to the hallways.
