It's time for the big reveal - the chubby girlfriend's eyes widen as her boyfriend unzips his pants. A massive, thick black cock springs free, pulsing with anticipation. She gulps audibly as he steps towards her, hands ready to guide him inside her heat. He slowly thrusts forward, making her squeal with delight as she feels the stretch of her tight walls around his enormous length. He starts off slow but soon picks up speed, pounding her relentlessly as she manages to climb on top to meet him halfway. Their moans fill the room and echo through the building as he continues fucking her into oblivion. With a powerful thrust, he forces his cock deep inside her, hitting her cervix and making her cum hard, squirting like a fountain all over them both.
