With each thrust deeper into his ass, Tarzan feels the heat and pain build to unbearable levels. His eyes roll back in his head, his teeth grit against the inside of his cheek as he tries not to cry out. But there's something about this strange creature that pushes him further; it demands everything from him, and he can't help but give it what it wants.

"Yes... please..." he moans through gritted teeth, his hand a blur as he brings himself closer to release.

Choking and gagging, Tarzan arches his back off the bed as he feels fingers push into his throat. The sensation is agonizingly pleasurable; it heightens every other sensation coursing through him, pushing him closer to the brink of orgasm. His hand moves faster on his dick, stroking furiously as he struggles against the invasion of his airways.

"More... I need..." he manages to gasp out between choking noises. "Please..."

Frozen with fear, Tarzan watches as the men in white approach. They prod and measure every part of his body, taking particular interest in his genitals. He winces at each touch, wondering what they could possibly want from him now. As they work, he notices that one of them is carrying a clipboard and making notes on it constantly.

The feeling of being turned over and inspected in such an intimate manner is humiliating beyond words. Tears well up in his eyes as the men prod at his anal opening with some sort of instrument, stretching it wider than ever before. They even insert a finger inside, causing him to cry out in pain once again.

Taken aback by the sudden intimacy, Tarzan's body tenses up at first. But as the strange animal continues to pleasure him in this way, he begins to relax...and enjoy it. He reaches out, running his fingers through its hair, feeling its soft skin against his own nakedness. The sensations are overwhelming and unfamiliar, but somehow right.

Pain shoots through Tarzan's body as the strange animal forces its massive member inside him. He arches his back, gasping for air as he tries to adjust to the intrusion. The creature growls softly, thrusting deeper and harder with each movement. It feels so different from what he's used to...but also strangely arousing.

Tarzan screams as the first blow lands, the pain beyond anything he could have imagined. It seems to last an eternity before merciful darkness claims him, oblivion his only escape from the unbearable agony. When he awakens, it's to the strange sensation of cool air rushing over raw flesh where his testicles once were. Nausea and dizziness assail him as he tries to comprehend what has been done to him, and why. But there are no answers;

all he knows now is that his life will never be the same. Slowly, painfully, Tarzan begins the long journey back to consciousness, unaware that the worst is yet to come.
