Sister and friends

Jogging by the cars I notice it’s my little sister Katie (22F) who I thought wasn’t coming back tonight. Along with her two friends cars, Sabrina and Brooklyn. Sabrina (22F) is a short blonde with hair going to her shoulder blades, B-cup breasts and an average ass she tries to grow. Brooklyn (21F) is a smaller nerdy girl with long black hair and Harry Potter glasses. She’s got larger breasts, borderline D cups, but not much of an ass. We would tease her for her in-balance of tits and ass. I got along with each of them since my sister has been friends with them forever. Sabrina is very straight edge and likes to be very cautious. Which is good since my sister is more adventurous like myself. Brooklyn is very nerdy and polite although she has a wild side. Brooklyn has always had a crush on me which I liked to use to tease her. Seeing my sisters light on upstairs i decided to enter through the backyard to be more silent in case my parents are still asleep. Not minding the warm rain as I unlatch the gate and enter the backyard. Even though the mud is annoying, most of it has washed off from the rain. Standing by the back door I grab my key as I debate jumping In the hot tub or pool before heading in muddy.
