Try to beg (and fail)

'Click', 'Click', It hadn't been 12 hours, Penny had obviously got it wrong, not that it mattered at this point, you can feel the mechanism around your cock and balls every time it clicks, and every click is met with the tube contracting fractionally in with and length. You don't seem to be able to call out, she must be doing her no voice trick again, wanting you to suffer, and Lexi isn't helping, still looking through different draws, lending over at the waist and showing you exactly what you cant have... yet..

"Oh, you have some good stuff we are going to make use of!", Lexi was calling out to you, occasionally tossing items over her shoulder, landing randomly between you and her, completely oblivious of what was going on. You scrunch your eyes closed and attempt to clam yourself, trying not to think of Lexi, completely naked in front of you, horny and only moments ago ripping your pants off to get to your cock.

'Click, 'Click', How did you forget, it's not just shrinking, you can feel the nubs of the spikes slowly descending from however they are hidden, starting to press against your delicate flash, only this time your excitement is so high your cock is pressing against them harder still. You struggle to control your breathing, everything hurting more, but you can't shift however the situation is arousing you more, are you enjoying this pain??

It must have only been moments, you were not paying attention with your eyes closed and attempting not to think more sexy thoughts about Lexi or the unstoppable crushing sensation on your cock. "Open your eyes!, You should be enjoying the show!", Lexi shouted at you, and so you did, opening your eyes you see she had moved a bench of some description in front of you.

You struggle to watch as she adjusts it, giving it a bit of an incline towards you, and lays on top of it, he legs held apart by some stirrups connecting to the sides and giving your first completely unobstructed view of her perfectly trimmed pussy. She has your attention now, you try and ignore the cage as you take in the sight of her laying only a short distance from you, spread wide and inviting, your eyes continue upwards and you spot it, a key on a chain around her neck and resting between your breasts. She just smiles at you as she holds a red dildo in her hand and starts rubbing it against her pussy, you can see how damp she already is. You cock responds to the sight and you groan in pain as the spikes dig into your cock, and Lexi just continues to smile.

"Please, let me out of this, I beg you, its getting smaller.....", you stammer out all at once, did Penny let you talk, or was Lexi right and the pain through your cock won out and let you talk, you sound **** and panting at the effort to just to say that, "... please..".

She raises a hand to her lips, "shhh", she motions as she starts to moan, you look to see the dildo sliding between her lips as she starts working a steady pace, he hand moves from her mouth to the key around her neck and just holds it. You feel yourself going silent again as you watch...

"You can enjoy my show, and..", she started talking between gasps, "if you manage to watch until..", she pulls the dildo out and points it at you, "..until I'm ready for you, then I will use this key I found.", you stare into her eyes as she waves the wet dildo at you, almost threateningly, "If you say one word, I'm keeping the key and..", she trailed off as she returned the dildo to her pussy and once again the show continued. Your cock screaming in agony as you fail to take your eyes off one of the most sexy scenes you have ever witnessed.
