Forbidden Incest: Massive Cock Stretches Sister's Tight Hole Until She Screams for More!

The humid air in the master bedroom thickened with musk as he pinned her against the cold sheets. His massive, throbbing cock stretched her tight, shaved pussy to its absolute limit, gravity pulling her ass down the length of his girth. "Fuck, it's too big!" she whimpered, her nails digging into his shoulders as he thrust deeper. The wet slap of skin echoed loudly, mixing with the salty taste of their sweat on her tongue. He grabbed her hips, forcing her to take every inch of his breeding rod. "Take my cock deep!" she gasped, eyes rolling back as he bottomed out inside her churning womb. The friction burned, a delicious sting that made her legs shake uncontrollably. "Cum inside me now!" she begged, feeling the hot pressure building in his balls. With one final, brutal thrust, he erupted, flooding her cervix with thick, warm seed. She squirmed as the warm fluid filled her belly, a mix of pleasure and overwhelming fullness. "Don't stop!" she cried out, needing more of his heavy weight pressing down on her trembling thighs.
