>to start with, it's me and my sister growing up with a bipolar mother who frequently went on drug binges, so my sister got used to raising me
>she's six years older than me
>don't see sister for months at a time because she's away living in an apartment with some friends she made in college
>when my mom goes away for a few months in prison (drugs), I go to stay with my sister in her apartment and 2 roomates.
>sister is not particularly thrilled with this arrangement to say the very least.
>I don't even have a room in their apartment, I sleep on a futon in a corner of the living room
>so I spend the first day or so on my laptop, not leaving the futon except to use the bathroom, sister barely talks to me, and I'm feeling pretty miserable
>during this time, I come to know my sisters roommates
>one, who I'll call Busty, was a brunette with very large, natural breasts, nice hips and ass but the tits really drew me in. Not saggy, or too big, but just right. Like Daddario's
>she was nice to me and also very flirty, often walking around in short-shorts and a tee without a bra
>the other roommate was also my sister's girlfirend, what would be a stereotypical tumblrina today, skinny and tomboyish, pixie haircut with pink and blue dye and just a nerdy boy demeanor
>then there's my sister, dirty blonde, almost brown hair, perky breasts and a round, tight ass
>during the first few days I see my fair share of them making out and getting handsy with each other
>that first friday night they're all home, at first drinking wine and liquor in the kitchen, then the roommates go upstairs and my sister comes up to me, tells me to stay downstairs and go to sleep, and under no circumstances to come upstairs. she turns the TV up and leaves
>turn it back down and listen, for a while just giggling and laughing
>then I hear someone let out an unmistakable moan.
