Sibling Impregnation: Beg for Another Load

Isaac’s cock slipped out of your gaping cunt with a wet schlick, his cum oozing down your thighs in thick, milky rivulets. Your womb throbbed, already cramping around the emptiness, your cervix twitching like a hungry mouth. The curse’s timer pulsed—29 hours left—but your body didn’t care. It screamed for more seed, more stretch, more ruin.

“Isaac,” you sobbed, clawing at his chest, your nails leaving red welts. “Please—fuck me again! I need it… I need your cum deeper!”

He grinned, feral and dark, flipping you onto your stomach. Your ass jutted into the air, your puffy, cum-smeared lips glistening under the harsh bedroom light. Isaac spat onto his cock, the saliva mixing with your juices as he rubbed his swollen head against your swollen clit.

“Beg louder,” he demanded, slapping his shaft against your sore folds. “Tell your brother exactly what you want.”

“Breed me!” you wailed, cheeks burning with shame, your hips grinding back against him. “Shove your cock in my womb—make me pregnant!”

Isaac’s hand fisted your hair, yanking your head back as he speared you in one brutal thrust. Your cunt squelched, overstuffed and raw, his thick shaft bulldozing past your battered cervix. The pain was blinding—your walls tore slightly, streaks of pink mingling with his cum—but the curse loved it. Your clit swelled, throbbing in time with his thrusts, as Isaac pounded your fertile depths.

“Take it,” he snarled, his balls slapping your clit with every snap of his hips. “Take your brother’s fucking seed like the **** slut you are!”

Your breasts swung beneath you, nipples scraping the sheets, each friction sparking fresh waves of agony and pleasure. Isaac’s free hand groped your stomach, pressing down to feel his cock bulging inside you. “Fuck—I can feel my tip punching your womb,” he grunted. “Gonna paint it white… twice.”

The pressure built, your body betraying you. Your cunt clamped down, milking him, your cervix suctioning his cockhead like a greedy mouth. Isaac’s roar shook the room as he came, his cum erupting in hot, sticky jets directly into your womb. You screamed, your own orgasm ripping through you, your clit pulsing as urine sprayed the sheets—a humiliating squirt that left you trembling.

The Aftermath

Isaac’s cock slipped out, followed by a gush of cum that pooled beneath your shaking legs. Your cervix remained slightly dilated, a trickle of white seeping out no matter how hard you clenched. Your stomach bulged faintly, stretched taut with his load, and your clit burned, oversensitive and raw.

Isaac collapsed beside you, his hand lazily fondling your distended belly. “Look at you,” he sneered. “My personal broodmare. Bet you’re already ovulating… begging for my kid to root in there.”

The curse’s timer flickered—28 hours left—but your body didn’t care. Your cunt itched, craving another filling.
