Our GPA Bet: She’s My Freeuse Property All Summer Long

I thought I was a sure win. See… I made this bet with my stepbrother. We wanted to see who was the biggest nerd. Who was the ultimate brainiac in the family? There was no way my stepbrother was going to beat my 3.8 GPA, but then it happened. He came home with a perfect 4.0! How was this possible?! I’d lost the bet, and that meant he got his wish - I was going to be his free-use fuck toy all summer long. The time of day didn’t matter. I was his to use however he wanted, whenever he wanted. I was his property, and my holes were open 24/7. Whether it was on the couch, while I was on the phone with my friends, or brushing my teeth. If he wanted to use me, all he had to do was pull down my panties and start fucking. The weirdest part? I kind of loved this new attention from my stepbrother… I never knew he felt this way about me…
