Lisa enjoyed all aspects of the martial arts, it kept her in great shape, she met lots of friends, and she was just naturally very good at it. She studied several different styles, earned a black belt in both karate, and judo; but loved street wise women‘s self-defense the best. She always loved going for a guys balls, and fantasized about getting to work over a mans nude balls. She tried it in bed with a couple of boy friends, but they couldn’t take more than a light slap. Lisa earned a living by instructing at a local gym. The owner opened in the morning for the 9-5 crowd, and Lisa closed the place in the evenings.

Lisa met Dan for a one hour tour of the gym, as a personal trainer. She was immediately taken by his good looks and his easy going personality. He showed interest in the free weights, and exercise machines, but they spent most of their hour discussing martial arts classes, especially self-defense. Lisa invited him to join one of her group classes, but he felt more comfortable in a one on one setting.

Although she was a manager at the gym, the job didn’t really pay that much. Personal training sessions were the key to increasing her income. Lisa had group classes late on Tuesday and Thursday, so Dan asked if he could come in Monday, Wednesday and Friday evenings. Lisa thought that was great, instead of waiting to lock-up the gym, she’d make some decent spending money with a well mannered, really cute rich guy.

Dan showed up 15 minutes early for his first lesson, and was surprised at how empty the building was. “Hey Lisa, are we all alone?”

Lisa said “There are two janitors, and maybe a half dozen people left in the locker rooms, but at this gym most people come in before or after work.”

They walked together over to the sparring room, selected padded head gear and sat down to stretch before they began to dress out. Lisa asked, “Are you wearing a cup?’

Dan blushed and said, “Yes, of course. Have you ever sparred with a guy who didn’t wear a cup?”

Lisa smiled at the thought, “Not me personally, but in one of my group classes a guy forgot his cup, but decided to spar anyway without telling anyone. The petite woman he was fighting dropped him like a ton of bricks with a knee two minutes into the match.”

Dan shivered at the thought and to hide his embarrassment said “ I guess that’s not a good idea”.

Lisa got a visual image in her head, which made her smile to herself. Dan saw her grin and figured he was making her uncomfortable, so he looked away. But she continued the conversation, saying, “I guess that depends on what you want to take away from this training. You won’t be wearing a cup in a bar fight, or if you’re attacked on the street. So, If you’d like to become an effective street fighter, then it would make sense to also condition your testicles to acclimate them to taking a hit.” Then it was Lisa who shifted her gaze to keep him from becoming uncomfortable.

Dan thought about that for a bit, an admitted out loud “that he grew up in private schools or with home tutors, and wanted to learn to defend himself. I’m not interested in attending tournaments or competing, I want to do this mostly for the conditioning and personal self defense.” He sat there with a real thoughtful look on his face.

Hesitating so as not to word it inappropriately, Lisa continued to look away as she said, “I’ve always wanted to spar with a guy naked. One on one, no pads, no cup, just real and natural, it just seems to be the most pure form of fighting, …can you understand that Dan?” She turned softly looking directly into his eyes as she finished speaking. Lisa looked away first, and lay back to stretch her thighs, purposefully pushing out her chest.

Dan began to ogle her body. Large firm chest, at least a C+ cup size, long toned legs, pretty face and long brown hair.. “Yeah,” he said a little too lustfully, “I wouldn’t mind fighting naked.”

Lisa couldn’t believe he really took the bait! Now to set the hook she added, “We’d have to do it after I lock-up, it’s not much, but this job pays my rent. I’d hate to get fired helping you out.”

Without thinking Dan replied, “I understand about discretion, and I’d be happy to pay for the additional lessons. Would you expect more money for staying late? It’s $35 an hour now, how about $50 for the later lesson?”

Lisa paused to think and agreed, “Yes, that sounds pretty fair. Maybe you could help me close-up the place, too.” But what she was really thinking, “Was this guy going to pay me to bust his balls? Pay me extra? What a deal!!”

Dan was again stealing glance at her unbelievable body thinking, “Will she really get naked here with me alone? That‘ll be worth $50 in it self!”

The first hour was pretty routine, Lisa assessed Dan to be above the level of a good green belt, but sparing below the level of a brown belt. Near the end of the hour, as he began to tire, she stunned him with a solid right hand to the left side of his face. Dan brought up his guard, and spread his legs to keep from falling. Lisa snapped a front kick into his groin so fast and hard that it sounded like his cup cracked. Dan bent over and backed up a couple of steps, asking “you’ll only kick half speed later on, when I don’t have my cup, right?”

“Of course”, Lisa reassured him, “but they are worse things than a front kick”.
