Javier Palmas, relaxed and horny from his sister's massage, feels his cock twitch as Samara's hands glide over his body. She notices, her breath hitching, her nipples hardening. With a glance at his eager eyes, she decides to indulge. She leans down, her blonde hair cascading over his thighs, and takes him into her mouth. Javier watches, entranced, as her lips stretch around his girth. She's a natural, bobbing and sucking, her tongue swirling around his tip. He grows even harder, his hips lifting off the bed. Samara moans, the vibrations sending waves of pleasure through him. She takes him deeper, her big tits pressing against his thighs, her free hand cupping his balls, until he's ready to explode.
