Chapter 22 My Half-sister

" Fuck." I groaned with my hand on my cock as I stroked hard. I couldn't believe I was doing this. Watching my sister's twerk video on Snapchat and touching myself to it. I moaned shamelessly, biting my bottom lip while trying not to moan out loudly. Her big ass bounced so perfectly as she whined her waist. She was wearing a tennis skirt in the video and I could see her beautiful thick thighs. I imagined my hands all over her thighs. I imagined grabbing her big butt as she rode my cock.
