Disposing of the Evidence

Flurry tilted the bottle back over her head and drank three mouthfuls of the potion. There was no serving size for this. The more you drank, the longer the effects would last. The whole bottle would generally last ten to fourteen hours, depending on how the recipient's body reacted.

"So, how long do we have to wait for it to take effect?" asked Flurry. "I mean, I'm okay with a little wait, but I'd like to know how long."

"Give it time," said Twilight, her eyes on Flurry's labia. "I've seen potions that only took seconds, and others that take hours. I don't think this one will take more than thirty minutes."

"Ugh..." Flurry flopped back onto Twilight's bed. "I was really excited about this. Why does it have to take so long?"

"It's not so bad," smiled Twilight, patting Flurry's knee. "We just have to find a way to kill thirty minutes. We could read a book, talk to each other, play a game of cribbage or--"

"I can think of something fun, too," grinned Flurry. "You've been eyeing my vagina since I sat down. Why don't you taste it?"

Twilight raised an eyebrow. "Doesn't that seem a little bit common at this point? You have me do that all the time."

"I know. But this time, it makes sense. I'm going to have you suck my dick as soon as it comes out, and this way, you'll already be in the correct position."

Twilight shrugged. Flurry had a valid point. If Twilight were to wait in this chair for everything to happen, it would be very boring, and she'd want to be ready right away. Granted, the time it took to stand up and kneel down wasn't long at all, but a card game would need to be put away.

Twilight dropped to her knees and licked her fingers. She'd had enough time to practice on Flurry's twat that she knew exactly how to please her at this point, and how to prolong her pleasure. It all began with a kiss, then a lick, then a bit of sucking on the flesh as her tongue probed her vagina. That was just enough to make her wet. After that, she would focus on fingering her, her tongue mostly focused on the outside.

Flurry could feel a warmth spreading throughout her body. It started in her chest, as her breasts began to shrink. There wasn't a whole lot there to begin with, but she was upset to see it go. Then there was the heat in her gut. She could feel something happening, and she was pretty sure it was the potions effects about to come into play. However, neither of them were expecting what happened next.

"Ow!" Interjected Twilight. Flurry's testicles had dropped out of her vagina, and her clit had suddenly grown into a massive cock. She was a very well-endowed princess. Or prince, as it was. Regardless of title, the member had shot up and appeared so suddenly that it had jabbed Twilight in the eye. "Watch what you're doing with that. It's not as easily controlled as you might think."

Flurry wiggled his hips, watching how his cock jiggled. "I have a swingy thingy," he chuckled. He reached down and ran his hands over it, moaning as he did so. "I can see why they love this. I love this." As he began to firm up, he stepped up onto his feet and whapped his turgid length against Twilight's cheek. "I know I was already in a position of power over you, but spanking your cheek with my dick is really giving me a tasty power trip."

Twilight was amazed at how completely the potion had worked. Not only had it changed Flurry's body, it had changed his mane and given him facial hair. He was now sporting a thick, wavy set of locks and big, bushy mutton chops. What was most beautiful, though, was the scent. Flurry had showered before going to the library, and had smelled sweet and flowery just a moment ago. Now, her balls were leaking a powerful, masculine musk that just made Twilight want to submit.

"Well?" asked Flurry, pressing the head of her cock against the underside of Twilight's nose. "Start sucking, Princess. We're on a timeline."

Twilight wanted to make sure Flurry experienced to the full benefits of being a stallion in Princess Twilight's bed. She started off strong, relaxing her jaw and throat with a spell she'd learned from Cadance, and sliding the whole length of Flurry's shaft down her throat in one gulp. The newly appointed prince couldn't take the sensation and fired off prematurely with a yelp, stumbling back onto the bed.

After a few deep breaths, Flurry centered himself. "Well, I guess I can't ever blame a stallion for popping off early anymore," he groused. "Not with how long I lasted."

"You had a powerful opponent," smiled Twilight, nuzzling Flurry's balls and taking in a big whiff. "You thought I has going to go easy on you? We've only just begun." Once more, Twilight's mouth was wrapped around Flurry's massive meat popsicle. She pleasured herself with her left hand, using her right to fondle Flurry's nutsack. If Flurry was out of bed again before sunrise, it would be a wobbly trip to the toilet. Otherwise, he would be either on his back as he was now, or on his knees.

Flurry wasn't on the same wavelength, though. After he was hard again, he stood up, braced his legs in a more stable stance, grabbed his aunt by the ears, and rhythmically began thrusting his hips forward and backward with a force that he didn't think he had. He was in control of Twilight, not the other way around, and he would use her body for what he wanted. If she was pleased by the end of the night, that was good, but it wasn't necessary. She was his toy, and he would treat her as such.

To his surprise, Twilight was into it. Unable to keep a hand on Flurry's balls without slowing his movement, she focused on fingering herself from both ends, letting the pleasure rise to her chest, where it came out of her mouth in the form of a moan. That vibration in her throat transferred into Flurry's cock, adding to the stroking action.

Flurry was no pushover this time. He managed to hold out for a good fifteen minutes before he held Twilight's head down, firing a heavy load down into her stomach. When she came up for air, she was sporting a big, goofy grin. "What's next, my charming Prince Flurry?"
