Second...

Still pulling on your cum clumped hair, the man reached down and aggressively pinched your rock hard right nipple. "Choose, or I have someone bite it off!" he demanded.

"The second one, the second...please!" you begged.
"I was hoping you would say that." he purred, now massaging the nipple. "I'm afraid I've become too excited from this experiment, and will have to use you during your punishment." Looking up abruptly, he yelled, "Bring in the creature!" At those words, your fear overtook you, the dread building from your stomach all throughout your body, and you began thrashing against your shackles, bloodying your wrists more, but **** to escape.
"Nooooo...please, I'm sorry, don't do this!" you cried, trying to think of some way out of this.

Then you heard the thud of heavy boots getting closer, and the snort of a humanoid beast. Facing the bottom of the bowl, you couldn't see what was behind you, but you knew what was coming. Squeezing your eyes shut, your body began shaking, and you were unable to keep from crying out as the large creature let out a guttural noise and you felt the warm air on your ass as it sniffed you. You could hear the excited snorts of the humanoid mutant as some men stroked it to it's enormous 18 inch length. "I've enjoyed this experiment, ダーリン." the Man said in your ear. Many men were around you now, some holding you still, some holding your head back, and some forcing open your mouth. The Man pulled out his swollen rod and began jerking off in front of your face. You felt the creature's dick maneuvered to your used pussy, then the violent thrusting began. His thick pole **** it's way deeper and deeper into you, tearing at your insides. You screamed in pain as it impaled you, rocking you in your shackles.

You felt warm liquid pouring from your destroyed pussy, and opening your eyes, you saw the deep redness spreading in the puddle of cum. The men brought your head back up as the Man erupted his semen on your face and filled your mouth. The thing continued pounding harder, it's heavy breathing and grunts raising goose bumps along your slimy naked body, and the sharp pains increased until it felt like something ruptured. Somehow, the overload of sensation deep in your pussy triggered a final orgasm, the pain only making it more intense. You felt the creature shaking as jets of cum began filling your womb, spraying hard enough to hurt. Then you felt light headed, and a warm numbness spread from your abdomen. "I enjoyed our time together, pet." the Man said sadly, as they let your head drop into the pond of fluids beneath you. You barely felt the creature's cock recede from your tunnel and the flood of reddish sperm gurgle out of your gaping vagina before your consciousness faded...
