He fills her ass with his black cock. His cock is thrusting deep into her ass. She begins to relish the feeling of his now strongly pounding his cock over and over into her anus. She hears his excited breathing behind her. She senses from his excited quickening humping of her ass, that he is near cumming. She raises her ass slightly and presses back. His hands take her ass and spread her cheeks,  providing incredible, deep, penetration. With a deep thrust, he slams his cock deep into her ass and releases a strong spurt of cum up inside her. She feels  he abruptly stop his movements and then the pulse of his cock as it releases wad after wad of cum inside her ass. The pure sexual eroticism of it sends her over the top, and she feels her own orgasm come crashing down on her.
