Beach towel sprawled out under glaring sun. Dad's girlfriend peels down those pink bikini bottoms, skin sticky with sweat and salt, climbs aboard his lap right there in the open. Thighs clamp down, fabric bunching at her waist — she grinds slow at first, feeling every ridge through the thin barrier, then picks up speed with sand grinding into knees. Hands dig into his chest, nails leaving red trails on sun-baked skin. He bucks up hard, her tits bouncing free from the top, nipples hard against the breeze. Flip to doggy — ass up high, cheeks spread by the salty air, cock slamming in deep with each wave crash nearby.
