They need a massage
You're lying back, bare skin stretched out under soft light, and those pale legs look like they've been on their feet all day. Toes pointed, calves tight, thighs begging for hands to work out the tension.
Smooth white skin from ankle to hip, not a tan line in sight. Every muscle visible under that porcelain surface, flexed just enough to show the shape.
Massage is one word for what those legs need.
