Passion in the Sun (1964)

This blonde chick with a tight, toned body and decent-sized tits is the only one in this one, but she puts on a hell of a show. Starts off touching herself on what looks like a medical table or a plain studio bed — fingers working her pussy while she plays with her nipples. The lighting’s bright and clinical, so you see everything. Later, she moves to a bathtub and gets all wet, running her hands over her tits and under the water. The camera stays close, so you get a good look at her face when she’s really into it. No toys, no partners, just her and some solid solo action. If you like close-up shots of a hot blonde getting off, this one’s got plenty.
