The shark's colossal, veined cock, a stark contrast to the human's petite form, slams into the victim with brutal force. The human's tight, wet cunt stretches to accommodate the beast's massive girth, their big tits smashed against the shark's rough skin. In a haze of fear and lust, the human grinds their hips against the predator, riding it in a cowgirl position before submitting to the beast's missionary thrusts. The shark's powerful body tenses, its cock pulsing as it unloads a torrent of cum deep inside the human, their bodies locked together in a taboo, violent union. The human emerges from the encounter, marked and filled, their body bearing the shark's claim.
