Manuel slid the little electric stun gun up across her tit meat till the two metal teeth were astride her cold hardened nipple.

"After your training is complete, you will be sold to the highest bidder at our monthly auction. You will no doubt fetch a good price, and we would'nt want your owner to be dissatisfied with us would we?"

Manuel pushed the trigger on the gun and electricity crackled between the two metal points again, this time with her nipple right between.

She screamed and writhed on the bed as Manuel held the device firmly against her flailing body. He let up after several seconds, and Amy gasped and sobbed as she tried to recover.

"When we discipline you my dear, it is really only to teach you." the blonde man said. "You will therefore thank Manuel for your punishment."

She continued to breath hard as her frazzled senses calmed down somewhat. She glared up at the man in anger. "Fuck you." she hissed.

He shook his head sadly and said something in a language she didn't understand. The big black man grabbed her ankle and pulled her left leg up and to the side. Manuel did the same to her right leg, as the blonde man took the little shock box and sat on the bed.

She grunted in a hopeless effort to resist the two men as the opened up her crotch to the blonde man's view. He slid his hand softly along her pussy mound briefly, then pit the box to her pussy slit and pushed the button.

Pain exploded in Amy's brain. Bright fiery bolts of lightning and multi coloured lights filled her vision as she howled and wailed in agony. Her whole body twitched and shivered and writhed against the men and handcuffs holding her. Her senses reeled under the searing assault on the most sensitive and tender part of her anatomy.

He pulled the thing back and gazed down at her trembling sweating body with considerable interest. "Such a small thing this." he smiled.
