My step-sister's big ass saves me from being caught watching porn

I've always been a fan of my step-sister's ample backside. It's simply irresistible, a true delight for the eyes. Today, I found myself alone in the house with her and couldn't resist the urge to indulge in my fetish. I sneaked a peek at her voluptuous derriere, lost in my own world of fantasies. However, my carelessness led to my dad walking in on me. Talk about a sticky situation! But my step-sister, oh my step-sister, she's quite the savior. She quickly took matters into her own hands, or rather, her own booty. She positioned herself right in front of her husband, her luscious curves on full display. Such a sight left him speechless, distracted from the earlier incident. But I didn't stop there. I took advantage of the moment, getting down and dirty with her. I took her from behind, my thick member finding its home in her inviting depths. A creampie later, and the evidence of my earlier misdeed was wiped clean, thanks to my step-sister's flawless posterior.
