In a cramped, makeshift studio, two Brazilian cousins, both amateur and bisexual, decide to experiment with each other and a homemade toy. The older one, muscled and inked, lies back, legs spread, as the younger one, slim and smooth, lubes up the toy - a massive, lifelike dildo. He teases his cousin's eager asshole with the tip, making him squirm. Slowly, he pushes the toy in, inch by inch, until it's fully buried. The older cousin moans, grabbing his own cock, stroking it in time with the toy's thrusts. The younger one watches, his own cock hard, as he fucks his cousin with the toy, their bodies glistening with sweat and lube.
