The room is quiet except for the heavy breathing of a young man and woman. She's on all fours, ass exposed, wearing a silk robe, and he's behind her. He slowly, deliberately thumbs her tight asshole, lubricating it with her juices. With a whisper, he asks if she's ready and she nods. He gently presses his cock against her sphincter, feeling it tense. He slowly pushes inside, inch by delicious inch, as she moans in pleasure. With each thrust, her robe shifts to reveal more of her supple body. They fuck like this for minutes - long, slow, deep strokes - before she turns around for a more intimate position.
