If you're looking for books with a vibe similar to 'CFNM Beach,' you might enjoy exploring themes of exhibitionism, power dynamics, or playful erotic tension in literature. I recently stumbled upon 'The Exhibitionist' by Charlotte Mendelson, which isn't identical but has that raw, voyeuristic energy. It’s more about familial drama, but the underlying tension reminded me of the awkward yet thrilling atmosphere in CFNM scenarios.
Another angle could be diving into Japanese literature like 'Snakes and Earrings' by Hitomi Kanehara. It’s gritty and unflinching, with a focus on body modification and control—kind of an edgier take on the power play you might be after. Not beachy, but it lingers in that space where vulnerability and dominance collide. For something lighter, 'Delta of Venus' by Anaïs Nin has short erotic stories with similar sensory focus, though more poetic and less situational.
