Your stepsister is working out in your shared room. You are watching her squat. I stop and ask you to stop watching. YOU SAY YOU CAN CORRECT MY POSTURE... I reluctantly let you. I do squats for you and when I turn around my stepbrother has a MASSIVE BONER!!! I tell you to put it away but you convince me to sit on the bed. Your stepsisters face is now at your cocks height!!! You put it on my face and slap me with it playful. I warm up to the idea of us fucking. I say you have to eat my pussy if you want to fuck me.... and you do. YouR stepsister lays on the bed and lets you fuck her hard!!! You tell her you want to impregnate her... and she lets you!!!!
