"Ah! Ui! Zotl!" Daring Do screamed the words out loud as she ran down the hall. Her eyes were sharp, she watched where the dust hadn't settled from the strange crypt raider. "You better not be going for that fetish!"

"You don't understand, Daring Don't, this is my destiny!" Ahui ducked under what he knew would be another strung-up tripwire. The patch ahead was not one he wanted to run through, however. The walls were smooth and the floor… the floor was covered in runes. He stopped dead.

Daring spotted the thief halt before a trap she, and likely he, knew very well indeed. "You gotta pick the right symbols, or you fall. I bet there are spikes." Daring spread her wings and pushed up and forward.

"Curse you!" Ahuizotl made a jump and laughed as his hands grabbed on to the mare's hind-legs. "Don't fall!"

"You idiot…" Daring struggled against the weight, bucked her trapped legs furiously as she was losing height. Pumping her wings, she barely landed on the other side of the trap. Ahui, didn't.

"Stop kicking! Do you want me to die?" Ahui clung for dear life to the bucking mare. He had been forced to step on the carved stones, which as luck would have it fell out from under him to reveal a huge pit filled with alligators!

Daring Do kicked again but realized one thing. "If you don't let go we are both going to fall!" Instead of bucking now, she tried to brace her legs on the ledge.

"A truce, don't let me fall, and I don't let you go." Ahui only had two things to grip to, and they were the mare's back legs. One slipped. "Deal?"

Daring strained and planted her slipped hoof more firmly. "I could buck you off… okay, okay." She held steady, as steady as she could. Her passenger was swinging something and, just as both her back legs gave way, a lasso launched, held by Ahuizotl's tail. It flew straight and true and just as it grabbed a low pillar Daring slipped back over the edge.

"Got you." Ahui held the mare's legs still, his tail supporting both of them. "You held by our deal, so I will too." Using his tail to coil around the rope, Ahui used his third hand to pull them up until he was on firm footing again. "Care to renegotiate?"

"You swine! Just pull me up!" Daring heard her nemesis' laughter as he did just that. "Alright, we are square, right?"

"Square? Sure, we are completely even…" Ahui grinned wide, showing off all his teeth. With a leap he was charging ahead again.

"I really hate you, sometimes." Daring gathered up the rope Ahuizotl had used from her own pack and gave chase. "This one's mine! If it wasn't for me, you would have been 'gator food!"

Their chase, after avoiding a few more traps, ended up bringing them both into the huge chamber at the center of the ancient pyramid. On a dais in the middle was a cup, a pure, solid gold cup. "The Chalice of Life is mine!"

Daring blinked, her memory a bit fuzzy on the name. "Chalice of Life? Wasn't that an artifact of the Amazonian Fertility deity?" She spread her wings and flew as fast as she could. Reaching down to her side with a hoof, she pulled her lasso up. Practice at swinging a lasso while flying had not been easy. Wings had gotten sprained, legs broken, and a fracture in one hoof still made her limp in the winter. But when Daring Do let loose with her lariat, it flew straight and true.

"What?" Ahui had his arms pinned to his side as Daring flew past him. "Daring-" Was all he got out as the mare collided with the column holding the sacred cup.

"Into the bag, don't touch it…" Daring pulled her pouch open, her wing was out of shape from the impact but she knew letting her nemesis touch it first would be bad. The cup tilted, started to tumble down to her. There wasn't time for a bag, she knocked her hat up and off, intending to catch the chalice in it.

"I don't think so!" Ahuizotl's arms were bound, but his tail was free. He grabbed hold of the lasso and tugged hard. He crowed in delight as Daring jerked along the floor, as she missed catching the cup in her hat and, instead, the big golden chalice landed on her head.

A wave of magic rushed from the chalice, the thing glowing brilliant white for a moment and blinding the pair of them. Blinking at stars, Daring Do shook her head, tossing the cup away as she tried to work out what had happened.

Ahui's sight was returning then, too. Something was really off, however. "What did you do?"

Daring's eyes were wide, that wasn't right. "You sound funny." As she said it, she realized she did too. Her voice was deeper, lower and… A hoof quickly shot down, between her back legs. "You bucking idiot!"

"What? Why am I smaller? Why is your voice like that? Why is my voice like this?" Ahui stared at Daring Do, something seemed odd about her.

"I would have caught it in my hat, it would have been fine! But then you had to make me touch it!" Daring Do was on his feet and stomping over to the much smaller Ahuizotl. "And you…" His nemesis was not just smaller, but much more… pony-like. "Now I touched it… this temple was a fertility site for amazonian mares. You know what that means?"

"Uh?" Ahui blinked up at the raging stallion. "That they had gold?"

"They came here to use the magic to turn one of them into a stallion and make them all hyper-fertile!" Daring Do slammed a hoof down. "So when I touched it, it turned me into a bucking stallion and you into a fertile mare!" He was panting hard, a smell in the air catching his full attention.

"M-M-Mare?" Ahui's tail curled under her and she suddenly jumped a few inches. "I'm a mare! Why…"

"Are you really going to ask that? This is madness, I am getting out of here." Daring tucked his wing back as best he could, despite the pain, and found the chalice. "At least I can get you back to the museum."

"Wait!" Ahuizotl jumped up. "You can't leave me here like this!" She tried to run, her forelegs still had hands, but her back ones were now a cross between feline and pony.

"I can and I will!" Daring trotted for the exit, then froze. "I forgot about this…" He looked at the stone-glyphs-puzzle. "And now I can't fly out."

"I can read those." Ahui was behind him, her voice sounding like she was going to cry. "If you help get me out, I can get you across that."

"You can read it? Why didn't you do that instead of grabbing my legs?" Daring turned and glared at the odd-looking mare. Something in him stirred at the sight of her and he quickly looked away. "Okay, if you can get me past this, I can get us past the rest."

Ahui had her legs better sorted, walking forward to the stones. "See, this is a variation on the same language used by the Sordid Tribe to the east." She reached a hand out to the first stone and put pressure on it. It held.

"That's great, just show me where to walk." Daring was annoyed at everything now, but the worst of it was he had to stare at Ahuizotl's rear. It made him feel strange, hot. He took a step closer before he realized it, only to have Ahui jump from the first stone to one further in.

"This way!" Ahui waved her tail around enthusiastically. "You know, I don't really care about all this junk, only reason I do all this is for the adventure." She bounced from that stone, to another. Glancing over her shoulder, Ahuizotl saw Daring land on the stone she had just vacated.

"I… I do this mainly for the museums… mainly." Daring sailed across to the next one, landing off-balance. He teetered and started to overbalance when a hand shot out and grabbed his neck. It was Ahui's tail and without thinking, the stallion clamped his mouth on it too.

Almost off-balance herself, Ahuizotl clung to the stone she was on and to the pony with equal measure. "Careful!"

Daring Do was caught, barely holding on by dint of his nemesis' tail. A strong smell hit his nose and he opened his eyes wide as he realized what it was. With his snout clamped on the mare's tail, Daring had his nose pressed almost right up against Ahui's vulva!

"One… two… three!" Ahuizotl pulled as hard as she could, yanking the stallion from his own perch and over her head. She had a moment to realize she may have pulled too hard before she was pulled into the air after the pony. "Leggo!"

The two—without any way to manage their 'flight'—landed in a heap together, thankfully on the other side of the trap. Daring was panting through his nose, the whole world seeming like it was both wrong and right at the same time. His snout wasn't near the mare's mound anymore, but a touch at something very sensitive had him smile, a silly, 'stallion' smile, as he bucked his hips.

"Get that out of my face!" Ahui tried to heave Daring off of herself and just managed to rub her face in the swollen shaft of the stallion. "Get off, get off, get… no! Don't get off!" A dribble had come from Daring's length and suddenly Ahuizotl wanted to be anywhere but there.

The scream from under him finally percolated through the hormone-soaked senses of the stallion and Daring flopped over sideways, hips giving a few more bucks. "All your fault…"

"Ugh, you got stuff on my nose!" Ahui lifted a hand to wipe it off, then froze. "This is disgusting!" Part of her, however, thought that it was far from disgusting. Between Ahui's back legs, her body throbbed in heat, in need. "This is all your fault!"

"You didn't!" Daring got his hooves under him, standing up and staring down at Ahuizotl in anger. "If you hadn't come here, thrill-seeking, I would have gotten that damned cup, I would have wrapped it up carefully, I would be out of here!"

Ahui's eyes were wide in shock, but the words barely registered to her. Daring Do was standing over her and he was… rampant. "What?" Her voice was soft, she couldn't stop licking her lips for some reason.

"I said, you are a nincompoop!" Daring turned and started stomping down the hall. Deprived of the almost hypnotic sight of the stallion's erection, Ahui shook her head and looked after Daring.

"Hold on, you promised!" Ahuizotl started to jog after Daring, grinning as she caught sight of the stallion from the rear; it wasn't as hypnotic as looking at him 'head on', but this certainly was a nice consolation prize. Her target got bigger and, without thinking, she plowed her head right into the pegasus' plot.

"Hey, what are you…" Daring froze as he looked back, Ahui looked completely absorbed in staring at his rear and then she noticed what the mare's tail was doing. Arcing up high, the thin, prehensile tail curved around and had that hand on the end planted firmly into her plot. "Ahui… are you okay?"

Even Ahui knew she wasn't, she had her plot up in the air, her forelegs… arms… thingies, resting on the floor. "D-D-Daring?" She whimpered, looking up she caught sight of her enemy's shaft again. Avarice beyond any she had felt for artifacts flooded her.

"Whoa, calm down, what are you-" Daring had to jump back as the agile Ahui made a dive for him. "What's gotten into you?"

"Nothing! That's the problem!" Ahui reached out and swung off a vine toward Daring Do, landing on the stallion's back. "Got ya!"

Daring took off at a gallop. His heart raced, the instincts of a mare with a strange and naughty 'male' on her back driving the now-stallion to bolt. Then something gripped him harder than terror. It was a single hand, wrapping around the base of his balls. It squeezed and his gallop reduced to a canter. It squeezed again and another hand found the base of his shaft. His canter became a trot. When the third hand found his medial ring Daring stopped and gave a deep cough.

"Good boy, good boy, just calm down, you want me as much as I want that…" Ahui's mind was awash in her estrus, her need for what the stallion had, growing by the second.

"Ahui?" Daring had trouble thinking clearly, three hands at once worked his new anatomy in ways that neither of them could really contemplate properly. "Ahui I gotta say, you need to get off or…"

"Or? Daring Do, What will you do if I keep squeezing, like this?" Ahui gave a tighter squeeze, in sequence, with each hand.

Daring's eyes half rolled back at the amazing attention. "I… I… Ahui?" Daring leaned to the side, fiddling with his canteen.

"What?" The musky scent growing in the tunnel was all Ahuizotl could smell, and she wanted more of it.

"Get off!" Daring upended the canteen, dousing both of their heads in the cool water. With a grunt he bucked and started bouncing around, trying to throw his now-distracted molester off.
