Instagram stepsis seduced me

When my stepsister asked me to help her with some Instagram photos I had no idea what she was luring me into. Well, taking those butt shots and lingerie close-ups eventually got me so horny I just couldn't resist the temptation when she started teasing my dick wanting me to fuck her. Damn, I drilled that tight pussy so good and slapped that sexy ass repeatedly as I drove my stepsister to orgasm. I came too, so fucking hard wow!
