Sis assisted me with air conditioner repair and I got to enjoy her voluptuous derriere and adorable underwear

I was struggling to fix the air conditioner when my step sister stumbled in, offering her assistance. As we worked together, our conversation turned dirty, and I couldn\'t resist the urge to fuck her. Her big, fat ass was irresistible, and her cute panties only added to her allure. We engaged in a steamy interracial encounter, exploring her tight, pretty pussy in various positions.
