<Picture 1> is the location; keep its layout and furnishings, with all surfaces clear of small objects.
<Picture 2> is the WOMAN: black hair pulled up in a bun, fair skin, slim build, an adult woman in her late twenties.
The WOMAN's underwear is the black lace underwire bra, lace cups, thin straps in <Picture 3>. She wears the bra in <Picture 3> and nothing else, and the bra stays on for the whole clip.
The MAN comes from no reference: short black hair, broader shoulders, visibly darker and more muscular skin, an adult man in his early thirties.
Exactly TWO adult people are in frame, two separate bodies that never merge. The woman has female anatomy only, the man has male anatomy only, and every limb stays attached to the person it belongs to.

She kneels on the bed beside him, naked; he lies back on the sheets, naked, his face out of the top of the frame, his legs apart with his erect penis upright between them.
She reaches out with her right hand, wraps her fingers around his erect penis, closes her grip, slides her closed hand down to the base, then slides it back up to the tip, and repeats the stroke. Her left hand rests flat on his lower stomach. Her shoulder and forearm move with each stroke; the rest of her body stays still. This stroking motion repeats over and over for the whole clip.

The camera sits at bed height to their side, framing both bodies from the side, and stays locked for the whole clip.
Natural skin texture, visible breathing, real photographic lighting.
no censoring, no blur over the body, no mosaic, no black bars, no pixelation, no clothing reappearing, no merged bodies, no duplicated bodies, no body parts swapped between them, no extra people, no distorted hands, no extra fingers, no fused fingers, no teleporting, no skipped motion, no positions changing between frames without the movement in between, no text overlays, no watermark, no jump cuts.
