As the stepmother, Susan, tiptoed around the house, she couldn't resist teasing her stepson, Alex. She whispered dirty thoughts into his ear as her massive ass wiggled enticingly in his direction. Finally, they found themselves alone in the house, and Susan made her move. She slowly lowered herself onto the couch, revealing her enormous black ass as she spread her legs invitingly. Alex couldn't believe his eyes. He immediately dropped his shorts and plunged his enormous cock into his stepmother's tight, warm pussy from behind, driving her wild with pleasure. Together, they moaned and grunted in harmony as they fucked passionately while Susan kept repeating how much she loved showing off her big, thick ass to him. She felt powerful and desired as they both reached climax, shooting their hot cum in unison.
