Blazing beach sand turns this solo tug into pure filth, no walls to hide the action. Heavy-bellied guy sprawls legs wide on a towel, gut sagging over his lap while calloused fingers wrap that veiny cockhead. Whos gonna spot him first with balls out like that? Grip tightens mid-shaft, foreskin sliding back slick with sweat — foreskin peels, pink tip bulges rock-hard. Outdoor breeze hits the wet slit as he jacks faster, belly jiggling with every pull. Purple head swells massive right before ropes shoot across the towel.
