(B) Randi takes the door in the middle.

As soon as Randi stepped into the plexiglass cubical a large box rose out of the floor. A monitor sat atop with 5:00 flashing on the read out. The busty red-head stared at the monitor for several seconds before saying, “Okay, where’s the puzzles?”

A voice came from the monitor. “Place nipples against the markers.” Before Randi could ask what markers, two circles lit up on the front of the box. Looking at them, she felt the fear of this challenge for the first time. But she knew there was no backing out. Taking a deep breath, she walked up to the box. The red circles were in perfect alignment with her stiff nipples. She swallowed the lump of fear in her throat and pressed her nubs against the cool, hard metal.

“You have five minutes to answer 3 riddles. Each wrong answer will result in a punishment. The time will start after the first riddle is read.” The voice paused as if for dramatic effect. Knowing Sandi, it probably was program that way. “A woman shoots her husband. Then she holds him underwater for over 5 minutes. Finally, she hangs him. But 5 minutes later they both go out together and enjoy a wonderful dinner together. How can this be?”

“What the hell? How would I know that?” Randi regretted the words as soon as they slipped out. The robotic voice sang, “Wrong!” Two robotic arms shot out and latched onto her nubs as if trying to flatten them into paper. The pain didn’t stop there. A jolt of electricity lightninged through her tits.

The agony tore a scream from her and left her so dazed that she almost didn’t hear the next riddle. The robotic voice sang, “When can you add two to eleven and get one as the correct answer?”

Oh God! Randi wanted to scream and rage. But the vicious contraption still held her tender buds in a **** grip. If she answered wrong, she knew the next “penalty” would be even worse. Still, the timer was rapidly ticking away and she had to “play” along or face a forfeit. “Um...when you first subtract um...10?”

“Wrong!” The recording sounded almost happy. The robotic arms crushing her nips spun in opposite directions a 180 degrees. Randi screamed out and tried to thrash free. Again the cruel machine added insult to injury. Another bolt of electricity blasted through her tits.

The pain fried her brain for several heartbeats. When she came back to herself, she half hung from her screaming nipples. “Wha...”

“Wrong!” The sadistic machine sang out.

“Wait! I didn’t hear...” Randi started to cry out. But the evil device wasn’t listening. Nipples twisted another 180 degrees, she thought they were about to be torn off her body. Her eyes boggled at the sight, her nubs looked more like two corkscrews than the beautiful buds they were.

While distracted, two more robotic arms came down. Before she could figure out what they were doing, they punched her nipples, piercing them almost at the exact time with two tiny bells. The pain drew tears from Randi’s eyes and made her cry out.

“Challenge failed, proceed to final challenge.” The voice chimed as the robot arms withdrew from Randi’s aching nips.

The merry tinkle of the bells as she trembled in pain was like pouring salt in the wound. She wanted to shout the walls down but she could see her cousin standing out side the exit to the chamber. She had no doubt Sandi would call forfeit if she did not go out and join her right away. Jingling the whole time, Randi **** herself to walk over to her evil cousin.

“Now what, bitch! How are you going to **** me next?” She snarled at Sandi.

“Tsk, tsk,” Sandi reached out and gave one of the bells a flick making Randi hiss in pain. “Now cuz, that isn’t anyway to talk to me? I’ve given you nothing but chances here. In fact,” She grasped the bells and started dragging Randi by her nips.

Randi screamed, it felt like the buds were about to be ripped off her. **** stop the pain, she quickly followed her cousin up to the third floor balcony. Someone, probably Sandi herself, removed a section of railings, making a small opening that gave a clear line of sight to the floor two stories below.

The flat-chested redhead pointed to the rafters. A pulley system was set up above their heads. “So, cousin, you’ve failed the speed challenge, the mind challenge, your last chance lies here in the strength challenge.” Sandi then pointed to the line leading from it to the large weight on the ground floor. Randi squinted. No, the weight was hanging a short distance from the floor.

With a laugh, Sandi patted her busty cousin’s shoulder. “Yes Randi, it is being held up by the line.” She clapped her hands and two robotic arms lowered from the ceiling. They held the lines to the weight and as they neared, the block lifted a couple feet.

“So, the challenge is simple cuz. You will have to hold this 100 pound block up for five minutes.”

The weight alone sounded nearly impossible and after the other challenges, she knew their was more. “And what’s the catch? What’s the awful twist you’ve added?”

A vicious grin spread across Sandi’s lips. “Oh, cuz, I think you can guess.” On another clap, the end of the line the robotic arms held moved as if alive. Like some time lapse film it “grew” toward Randi’s swollen melons. As it neared, it split in two, joining with the nano-wire rings squeezing her jugs.

Teeth bared in a snarl, the busty redhead growled, “I can’t believe you! There’s no way!”

“Oh but there is, I’ve done the math.” Sandi pointed at the block. “Hold the block up for the five minutes and you and Daisy go free - no harm. If you can’t the block will hit a sensor which will signal the rings to collapse all the way.”

All the way! Randi swallowed thinking how terrible this sounded. How could she ever hold that much weight with just her tits?
