My sexy girlfriend, Katie Kush, was on the bed browsing Instagram. Seeing her ass made me horny, and I started playing with her pussy and pulled my dick out, jerking it off. Katie began shaking her ass, teasing me with it, but she couldn't get off Instagram. I started to slowly fuck her from behind while she was on her phone. We had a good fuck, and as a thank you, I gave her a nice mouth cumshot.
