In the dim room, a small sister-in-law with a curvy body sneaked into her brother-in-law's room, and her sister was having a bloated stomach because of the fetus, so she didn't know anything. The little girl knelt down, her eyes gleaming with lust, pulled off her brother-in-law's pants, and grabbed the big hard cock that was erecting with lust. Her mouth was closed to the tip of the cock, sucking violently as if she wanted to swallow, her tongue licking along the body of her dick, and saliva gushed out to make it wet. Her brother-in-law groaned, his hand clutching her hair, pushing his hips against her throat. Then the sister-in-law crawled up, took off her thin shirt to reveal her white breasts and stiff pink nipples. She rubbed her wet pussy against his thigh, whispering, "I crave you so much, I can't fuck you, let me worry." Her brother-in-law turned her over on her stomach, spread her round buttocks, and his tongue rushed in and licked her pussy from the anal slit to the swollen pussy. The sister-in-law curled up and moaned in pleasure, and the pussy juice was pouring wet with the sheets. Unable to bear it, the brother-in-law thrusts his hard cock into his sister-in-law's pussy from behind in a hard doggy style. Every click was the sound of flesh patting his cock, his cock going in and out deep into the womb, making his sister-in-law scream in pleasure, her pussy contracting tightly around the body of her cock. "Fuck me hard again bro, I want you to cum full of pussy!" she begged. He sped up, squeezed his sister-in-law's nipples, clicking like a drill, sweating profusely. Finally, he growled and shot hot sperm deep inside, his sister-in-law trembled to orgasm, her pussy squirting with water. They hugged each other and breathed heavily, satisfying the long-pent-up burning, promising the next secret fucks.
