Way beyond any embarrassment at this point, Dan hoped for a ‘happy ending’ to Lisa’s examination. He had visions of her stroking him, or better yet leaning over to service him orally. Instead she began talking about other types of attacks that he might encounter. Dan wasn’t paying too much attention to her words.

He was nearing an orgasm, when Lisa seemed to slap is nuts with her right hand. He propped himself up on his elbows, and looked down to see his balls stretched down to the bottom of his scrotum with her left hand. Meanwhile her right hand was squeezing up from underneath his sack. She was talking, “…while a kick or a punch may land harder, if someone manages to grab your testicles - they can exert the pressure for a much longer time. They can pull them…”

“Holy Shit!!” Dan screamed in a very high pitched voice.

Lisa continued her lesson“…they can twist ‘em, or drive a finger into them by using their other hand. This is especially painful if they have long fingernail.”

With each new description she was demonstrating his vulnerability. “Oh No,… Easy, …Please Nooo…” Dan was beginning to sob. His legs were shaking uncontrollably and he was getting tunnel vision as he began to black-out.

“There” she said looking at the clock on the wall, “thirty full seconds of squeezing. You did great for your first lesson. I’m very proud for you.”

From the way she said this, Dan though she was done with her lesson. He sighed a breath of relief, and after she stood up, he rolled onto his side to relieve some of the pain in his balls.

Lisa got up, had a drink of water and began to get dressed. He watched absentmindedly as she put on her briefs and sports bra, liking the fact that she left her blouse, pants and shoes off in anticipation of a shower. He was feeling better, and thought about following her into the locker room, when he realized she was speaking again. Something about other attacks…from behind…?

Dan had rolled onto all fours like a dog. Unable to stand erect just yet, he rested his face on the cool matted floor. It felt good to keep his legs apart, it relieved some of the pressure on his black and blue balls. “Shit are those my nuts?” he thought looking back down between his wide spread knees. They were a dark funny color, and hugely swollen, they didn’t even look like his nuts.

While he was watching his balls dangle underneath himself, he saw a pretty foot getting closer very quickly. He saw the impact with his balls, driving them up into his stomach. The sound it made was weird, a slapping, wet sound. Then the pretty size six foot swung back away and his funny looking balls bounced violently up and down - “nice manicure on her toes, pretty color” he thought.

Just then two things happened at the same time. Pain swelled up through his stomach into his brain, a deep, throbbing, hot, pain. The second thing he noticed was the pretty foot coming back towards those bouncing balls hanging under his ass.

“Oh Hell No” was all Dan had time to think. He didn’t even have time to look away, just witness his ball disappear between his stomach and her foot. This time he saw his feet, as his knees were lifted off the mat a good six inches. Then everything went black and silent.

Dan fell forward flat on the mat, spread eagle and stationary. Lisa saw his nuts laying on the mat unprotected and continued her explanations of different ways his testicles were vulnerable. “With your testicles flat on he ground like this, an attacked could easily stomp them into putty. I won’t put my full weight on them, grind them into the mat, or stomp them with force. But you need to understand the danger of laying here like that.”

As she spoke, Lisa was curling the toes of both of her feet over each of Dan’s balls to keep them from squirting away. “Slippery little devils…there, I’ve got them now. Can you see how this is like a hand squeeze, the pressure can be kept up indefinitely by an experienced attacker.” She watched as his nut meat squished out between her toes, dramatically dark between her white toes. She was getting very wet between her own legs, regretting having replaced her panties.

It was a full two minutes before stepped off saying, “see how you were held stationary by my feet. You were unable to get up, or even roll away. This is very effective and dangerous.” Lisa was unaware that he had been unconscious for this entire foot maneuver. She was too excited to wait, she drove her hands into her briefs and furiously began to rub on both sides of her clit. “Dan, I’ll go shower now, and let you recover for a while.

Lisa didn’t even make it to the locker room, she stopped at the first padded bench she came to in the Nautilus weight machine room and finished her orgasm. Only after she finished moaning loudly, did she realize she could be seen from the front windows. Fortunately most of the lights were off inside, and nobody was outside looking in at her. She continued on to the showers smiling and blissful.
