My stepsis is always trying to get my attention, I thought she just loved annoying but today it was a little different... She was really begging for me to focus on her and if I couldn't take the hint she pulled out her tits and told me that if I didn't fuck her she'd tell our parents that this whole thing was MY IDEA? We pinky swore that we wouldn't tell so fuck it. I started exploring her body with my hands, pleasing her made me so hard - I couldn't wait to feel her mouth. 40 minutes of pure pleasure with her blowing me, sitting on my face while she took my cock down her throat, riding me and letting me feed her pussy from all angles. She made me pinky swear AGAIN not to tell with my cum painted all over her face
