Karen naked in school (Part 3)

Generally speaking, Discipline is taking and enforcing control of another person for the purpose of sex. Bondage is limiting their movement. S&M is inflicting pain and accepting the inflicting of pain for sexual purposes."

She smiled. "The collar Karen was wearing is an example of both a bondage and an S&M device, since it can be used for either purpose or both. The classic example of just an S&M device is the whip." She held up several examples of whips, from a small one to a big bullwhip. "Obviously, some will cause more pain and harm than others."

"Are you going to demonstrate the whip on Karen?" a boy asked.

I shivered and blushed hard, but she shook her head.

"We have several other S&M devices to explain yet today," she told the class. "Some cause moderate pain, like the nipple clamps we showed you earlier." It hadn't felt like moderate pain to me, I thought. "That should really count as an S&M device," she went on. "Also, there are butt plugs, which are meant to be inserted anally." She held up a few rubber plugs. "They're basically a type of dildo," she told us. "They're used to prepare someone for anal sex. After using one of these, anal sex is considerably less unpleasant at least by comparison," she said, wrinkling her nose.

"There are straps and such for locking most of these into place. They can thus be used as punishment devices," she told the class, and held up a belt-sized strap.

"Show us!" one of the boys called out, grinning.

She blushed. ...

... "All... right." She looked at me, then sighed. "We'll demonstrate this one on me," she told me, a little reluctantly, I thought.

She picked up a tube of K-Y jelly.

"Isn't that cheating?" the boy asked.

"No!" she said sharply, then blushed harder as he laughed. She covered the end of one of the butt plugs with the K-Y jelly. "It has to go all the way in," she told me. "Hold it up so it goes in when I... sit on it."

I set it against a chair so it pointed up, and she positioned herself above it, then slowly lowered herself until her buttocks touched it. "Hold it steady," she said so only I could hear, and I clutched it tightly. She pulled her buttocks apart, then slowly lowered herself onto it.

"Ohhhh... OHHHH..." she groaned. She stood up, her face purple from the pain, and wet from tears. The butt plug lifted up with her, and she started reaching back to pull it out.

"Don't do it!" I told her quietly but urgently.

She looked at me, then forced a slight smile. "Thanks!" she whispered, then took a shaky breath, and lowered herself to push the plug the rest of the way in. "God, that hurts!" she gasped out, unable to stand up straight.

The boy came to the front of the room, and picked up one of the straps Miss Hooker had demonstrated earlier. "Is this one of the devices used to lock the butt plug in place?" he asked her.

She nodded.

He quickly wrapped it around her, connected it to the butt plug, and locked it into place. "Ah, and here's the key," he ...
