Harem Alliance

"Now, those of you that were in today's original lecture, this is a spectacular example of what not to do." Twilight wiped the cum off of her face, then sucked it off of her hoof. "As you can see, this zebra didn't last more than a minute down my throat. For him, this was a race to the finish line." She pointed to the orange line on the board. "He had two hours to spend once the coupon was activated, and he's already turning flaccid on my desk before ten minutes have passed. That means that more than seven eighths of his coupon are wasted."

Her hoof shot backward to fondle his balls. He wasn't done, yet. He just had to firm up before he could do anything.

"Since we are demonstrating, I think this is a good opportunity to explain why edging is a better method than just running to the finish line over and over. Every male has a refractory period. Some of the more impressive studs out there are capable of making their refractory period shorter, but this is a pretty rare trait. It usually lasts several minutes; more than enough time to blueball a mare."

As she said that, her other hoof shot down between her legs, and she started masturbating in front of her class. The shock of this caused her to gasp loudly.

"Gah!"

With a few murmurs from her students, she composed herself. "As I am demonstrating now, in the event that your male partner enters his refractory period, you can prevent yourself from being blueballed by edging yourself. Softer than this, though!"

Her hoof slowed down.

"That's better. Now, this is still an inequivalence, as recovering from this and finishing what's been started will leave him with two and me with just one, or if he manages to work any more, best case scenario, he'll have one more than me. That's why it's best to synchronise from the very beginning."

As he began to stiffen up, she found herself climbing up on top of him. "We will now demonstrate edging with a partner. It's a lot easier by yourself, which is why I encouraged you to practice on your own, but it's both possible and more fun with a partner. And, like all forms of good friendship, the basis for this is entirely contingent on good communication. When I am close, I will say so, and I'll take a moment away from him to lower my excitement. Likewise, when he is close, I will pull away and let him take a break."

"Can we practice?" asked Spike, raising a claw.

"On your own," waved Twilight, seeing that some of the students were already trying to. Gallus was very clearly rubbing his cock in sync with her hoof, as if trying to replicate what the zebra was feeling, but he stopped as soon as Spike asked permission, as if doing so might be the wrong thing to do. "I will let you practice on your own to acquire a feel for it before you start trying to feel for somepony else's. But, I want to hear you all giving signals. Tell your partner, in this case, your hoof or claw, to stop and wait. If nopony cums before the bell rings, no homework for a week."

With an offer like that, everycreature reached down between their legs and started to rub frantically.

"Remember, you need to last a little over an hour, so take it as slow as you need to."

Everycreature slowed down. None of them wanted to finish first and be the one that landed them all with extra homework.

With a nod, Twilight lowered herself down onto the zebra. He was a good size, and the look he was giving her showed an attentiveness that she'd not seen in some of her other partners. He was going to listen, she was sure of it.

"Okay, feel free to warm up a bit. What is most important at the beginning is that we cross that lower limit, but not the upper limit. And once you've crossed that first line, just stay there. Don't try to cross the second line, and don't let yourself fall back behind the first!"

As she warmed herself up slowly, she took special care to focus on her partner, to see when he was nearing his climax. Crossing the line with him would lead to failure on her part, and how could she possibly expect her students to trust her word when she couldn't do what she told them to do in a demonstration? Her integrity was riding on this, so she had to hope that he didn't force her to damage her credibility.

She could feel him starting to throb, and he let out a small whimper. The magic forced her hips up, as he didn't want her to make him the reason everyone else had homework, either.

"Listen, there," said Twilight. "He was close. He was almost there."

"You slide with no effort, just comfort and ease," he huffed, not remotely sure why he was so close already. "Are you really that good, or am I just easier to please?"

Twilight shook her head. "This is your first time using lube, remember?" She lowered herself back onto him slowly, so as not to set him off. "You've never felt a hole so slick as my pussy, not because I'm the best at sex; that fact is unproven at best and up for debate at worst, but because smart ponies have been hard at work making sex both safer and more enjoyable, the cool, refreshing tingle you feel is the result of that menthol I listed as an ingredient." She turned to the class. "Heed my advice; invest in some lubricant. It will improve your sex life."

With a general consensus from the class that they should be using lubricant more often, Twilight returned to her temporary paramour. He'd calmed down enough that she could start moving again, and she did so slowly. This was going to be a long session. But that was a good thing. If she could prove that she could give them longer, stronger sex, that was going to improve their view of her as an authority on the matter.
