Eu peguei a meia-irmã nerd lendo um livro erótico e ela me mostrou as coisas imundas que ela está aprendendo

I’m not good at college, and with this big test coming up, I’m going to be totally fucked if my nerdy stepsister Sera Ryder doesn’t help me out. But when the stubborn girl won’t budge, I steal her glasses to make her pay! The only way I’m giving them back is if she sucks my thick cock. Turns out, she’s not as prude as I thought she was. And when I catch her reading an erotic book, she shows me some of the filthy things she’s been learning. A couple of days later, I show my stepsister that I passed the big test with flying colors, and she rewards me with a cock ride that completely drains my balls.
