In a tight, dimly lit room, a woman on all fours offers her ass to her lover, eager to feel his cock like a dog in heat. He obliges, his thick shaft sliding into her dripping pussy with a low growl. She moans, pushing back against him, their bodies moving in a rhythmic dance as old as time. His balls slap against her clit, sending jolts of pleasure through her as he pounds her relentlessly, their bodies covered in a sheen of sweat.
