Prompt

She is fucking him from behind with deep thrusting of her hips, heavy humping motions, his whole body is pushed back and forth with each thrust, her breasts bounce slightly, he is making very quiet grunts of exertion and is mostly silent while she gives low womanly moans of pleasure, she says in a low seductive voice "Oh my god lil broh, I'd have started using your ass way sooner if I knew it felt THIS good", she holds on to his waist with both hands, after a few more thrusts she cums intensely and repeatedly and thrusts even more deeply into him, her thick and stringy white semen overflows down their legs and onto the floor, she has smug and satisfied expression, no camera changes, he remains mostly out of frame
