You went back into the house and after a while you decided to take a shower and clean up. Not because you feel bad for your sister but because the smell of shit really bothered you. Also, although it would be great to watch your parents yell at [insert name] for shitting everywhere in the house, you love your Mom and Dad and don't want them to clean shit. During the shower you had your sexy 19 year old sister's body to yourself. You enjoyed the shower as the water trickled on your body. You soaped the 34B breasts and loved touching them and you moaned. Hearing your sister moan was pretty hot. Hearing her moan your name was even hotter and it was getting you wetter and wetter. You took the showerhead and held it above your pussy as you kept moaning and moaning wanting more. You need another shower from all your new glorious vaginal juice's. You dried off. You looked in the mirror and played with your new long blonde hair. [Insert name] is really hot with her hourglass figure, 34B breasts, blonde hair, firm ass, and green eyes. You then put on a pair of blue yoga pants and a black sports bra. [Insert name] used to play tennis in high school and was really good. So good in fact, Coach Thompson yells at you asking why you cannot play at the same level as her. Using her memories you put your long hair in a really cute braid. You then took your phone and took some selfies. Then her phone dinged. It was a notification to complete a quiz. Your sister [insert name] is a math major at a local private university on academic scholarship. She is trying to get her master's through an accelerated 4 year program which requires summer classes. You log on to her student account and begin to take the quiz. With her memories and knowledge the quiz was so easy. Instead of just flunking you were going to do something else.
While flunking would upset her, what you were about to do would tick her off even more. You see [insert name] loves to brag about how she has gotten nothing less than a one hundred in her life and how she brags about her constant 4.0 GPA. By barely passing the quiz you would ensure she didn't get an A in the class and her perfect 4.0 wouldn't be around anymore. You and her would be in the same GPA range 3.7-3.9. Sure she would still get her degree but this little detail would piss her off until the grave.
After that you decide to get your phone. First you use her memoires and write down all of her passwords. You then record many videos of her saying as many racist, xenophobic, and homophobic things as possible. While ruining her life now seemed fun, you wanted something to hold against her forever. Making her do your bidding until she died. You then got a tripod and started to take photos of your sister in suggestive positions. Then you stripped of your clothes and looked at your naked sister's body. She was going to be the star of a movie. You press the record button and come out her bathroom with her toothbrush. You then take her electric toothbrush and turn it on exposing the brush head to your pussy and moan. You can feel her vaginal fluids on the brush head as you continue to moan. You then take the brush and put it in your mouth licking it like a whore on a cock. You then shove her fingers down your hole and moan very loud. You then grab her pillow and hump it like no tomorrow. After a while you collapse on the bed in pure bliss.
