Private Gold 63: Sex Experiment (2004)

The girl with the short blonde hair is on her back, then bent over, taking it hard in both pussy and ass. The brunette with the tattoo is doing most of the action, riding and grinding deep with a strapon attachment. Camera stays tight during the anal — you see every thrust, lube dripping, her ass clenching after each penetration. They switch to missionary at one point, but it’s still rough, her head pulled by the hair. Lighting’s flat, studio-grade, softboxes all around, no mood lighting. Metal grid in the background gives it that cold, clinical vibe that fits the ‘experiment’ name.
