On a yacht, four friends - Joy, Karol, Cachinhos, and Pernocas - decide to spice up their trip. The redheads, curious about each other and Pernocas' enormous cock, start a passionate game of truth or dare. Clothes shed, bodies entwine, and tongues explore. Pernocas, hard as the yacht's mast, watches his friends' inhibitions crumble. The girls, fascinated by his size, take turns sucking him, their natural tits pressing against his abs. In the open sea, they forget about the world, lost in the pleasure of each other's bodies and Pernocas' throbbing cock.
