Prompt

Use attached image as starting base. Fixed shot, static camera, match original lighting anatomy and angle. Gym. Muscular purple-haired woman in a black leotard standing beside the old man in black briefs. She notices the huge bulge in his briefs and looks surprised, eyes widening, mouth opening a fraction. Her face stays visible. The old man looks at the viewer with a devilish smug grin. She steps in closer. He puts his hand on her ass and squeezes her ass cheek. She turns her body away from the viewer but keeps her head turned back so her full face stays visible. His hand stays on her ass, squeezing. She reaches down and feels his bulge over the briefs, rubbing the thick outline slowly. Her expression shifts from surprise into lust, breathing faster, getting visibly turned on as she rubs it. Scene ends with her smirking at the viewer. He keeps the devilish grin. Slow sensual motion. Gym ambient sound, her soft gasp, his low pleased chuckle.(huge bulge in briefs: 1.3), (surprised look then lust: 1.3), (hand squeezing her ass: 1.3), (she rubs his bulge: 1.3), (head turned back face always visible: 1.3), (old man devilish smug grin: 1.3), (ends smirking at viewer: 1.3), 15 seconds
