She was showing off her amazing body for you, and you were having the most miserable time of your life. She was going slow; showing off every curve, running her hands all over her body (and occasionally yours). In the last 45 minutes she had only taken off her skirt. She had almost shown you her breasts a few times, but every time, at the last moment, she had pulled her shirt back in place. You had never seen anyone look so sexy. She had you mesmerized.
You were so caught up in her beauty that you could almost forget the gut-wrenching, white-hot agony in your balls. She must have noticed that you almost looked comfortable, because she sensually came up to you....leaned in close.....reached down to your groin.....
......and tightened the jaws on the cold, hard shop vice clamped down on your nuts. Your balls had been in vices and clamps before, but nothing had ever felt like this. The tempered steel was unforgiving, uncaring of the soft, tender orbs trapped in its jaws. Those jaws closed a fraction of an inch and your balls had no choice but to give in. You could feel the flesh in your sack squish as it was forced to acclimate to its new, narrower prison. Renewed pain flooded your body, bringing with it a stream of tears and a scream that was only partially silenced by the skirt stuffed in your mouth (it suddenly occurred to you that silencing your screams might be the only reason she had even taken it off). You desperately hoped that your balls would still function when this was all through, but you knew that you had no control over how far she was going to take this.
You felt a moment of comfort as she coaxed an erection out of your cock; a brief reprieve in the midst of a hurricane of pain. She stroked a moment longer, enough to fully reawaken your sexual desire, then she stopped. She took one nail and ran it up your stomach. Her nail continued gently traveling up your chest, your neck, your chin. She used it to raise your chin and look you in the eyes as she said, "eyes on me." Then she retreated to her doorway and continued the show.
You had no idea how long she would want to keep this going. She seemed to truly enjoy being looked at with lust and longing, but she clearly wanted to make it severely unpleasant for you. Half an hour later, she still had not removed any more clothes, but she must have reached a critical point. She pulled over a chair, sat down, and started to masturbate.
Again you were mesmerized, again you started to forget the pain in your balls, and again she seemed to know it. She clearly hadn't finished, but she stopped anyway. You were screaming into your gag and straining against your bonds the instant she started moving your way. You would gladly have submitted to any of her other tortures, if only you could beg her not to crush your balls any more. But nothing could stop her. She reached down and tightened the vice.
The resilience of your testicles astounded you, but that didn't stop the red haze of pain that became your entire world. The red haze started to fade to black, and the pain became muted and dull for a moment. Then you felt the sharp sting of a slap to your face and you came back around. The pain was back, as strong as ever. She grabbed your chin, turned your head back, and said "eyes on me." She didn't waste any time on your pleasure this time; she had an orgasm to return to.
It didn't take her long at all once she started back up. Before you knew it she was moaning and clenching her thighs. You were particularly interested in the way her breasts were heaving with every breath once she finished. It was an amazing sight.
Once she came down off her high, she got up and headed your way. You were instantly terrified that she was going to tighten the vice again, but she didn't reach for it. She got on her knees in front of you and started using one finger to idly play with your cock. Once you were fully hard, she leaned in and took it in her mouth. You began to wonder what an orgasm would feel like, coming from balls that were still being flattened. You needn't had worried about that.....
Only a few seconds after she started you felt another explosion of pain. While you were busy staring at the top of her head, she had reached up and tightened the vice. Not much, but enough to get you screaming again.
"There. That was fun for you, right?"
That was most certainly NOT fun for you, but you only hesitated for a long as it took her to reach towards the handle on the vice.
"I thought so. It was definitely a blowjob that you'll NEVER forget." (5 seconds of dick-sucking at the end of an hour and a half of torture did NOT make the entire experience "a blowjob", but you promised yourself to never mention that to her; you had no desire to make this woman angry.)
She calmly rested her hand on the handle of the vice. She didn't turn it, but the nervous anticipation was somehow worse.
"You'd like to do this again, wouldn't you?"
Was this chick fucking crazy?! Of course you didn't want to do it again. NEVER again! Your balls were almost as flat as pancakes and none of her other tortures had ever come close to causing this much pain.
"Let's put it this way: You can agree to go back in chastity, and we can do this again very soon, or...." She tightened the vice another fraction of an inch. "....I can just finish the job and find another boy to play with."
