This happened last week. I (25M) and my 3 friends (also 25) all went to a bar downtown a few blocks from my apartment, and the night was average, but we had done a few lines through the night and when the bar closed at 3, we were still in a partying mood. So we all walked back to my apartment, and in the lobby we ran into my neighbour.
My neighbour is a smokeshow. I'd seen her at the gym, around the building, and we'd said hello, but never exchanged names (her name was Chloe, we later learned). She was white with olive skin, about 5'9", with a ridiculous ass and tits that were around a 34C. She was around the same age as me, by my guess. When we ran into her in the lobby she looked like she had just come back from a club.
