Spike leaned back, the silence of the castle music to his ears, the last week had been hectic as shit, and he was more than happy that Twilight had taken Starlight and the girls off to who knows where to do who knows what. Spike had one thing on his agenda for the day, do nothing and a lot of it. He had just gotten comfy in his chair when the entire castle shook, and maniacal laughter echoed through the halls. Spike jumped up, ready to run and get Twilight, before remembering she was long gone at the moment.

"Well fuck me then." He muttered as he ran out of his room and to the source of the laughter, he found it in the Cutie Map room, and he only just managed not to fall and land on his face, when he saw it, taking up the entire room stood a giantess purple Sphinx, who looked down at Spike and laughed.

"Well hello." She said as the doors slammed shut behind him making him jump, Spike turned to see who had done this and found no creature in sight

"Magic monster, yay," he thought as her voice caught his attention "I sense that it is just you and me in here. I had come to battle the Princess, but I guess you will do." The Sphinx got on her hands and knees as she looked down at Spike, who knew that she expected him to be terrified of her, and he would have been to, had she been wearing more than a tiny amount of wrapping around her chest and what basically amounted to a thong. the fact that the position she was in gave Spike a good view of her figure didn't really help either, still Spike acted a little scared, if not just out of common courtesy.

From her view the Sphinx saw a scared dragon wearing such baggy clothes that she could not make out his body type, after a second she placed him on being slightly overweight, and continued speaking"I will be taking ownership of this castle and, once all the citizens of the populated land have been properly enslaved, the land surrounding it."
"I respectfully decline your offer," Spike called back, earning an eyebrow raise from her. "What? Can you blame me for trying?" He asked.

"Fair enough," The Sphinx replied with a cocky smile "Since my original target is not present, and you seem to be going along for the roller coaster that is this ride, Let say we cut this short and sweet?" she raised three fingers as she went on, "I will tell you three Riddles, should you get more than one of them wrong I will be taking full control of this area."She smiled as Spike took that in.

"Why give me the option?" He asked, more than sure that the Sphinx could just bink him away should she want to.

"Little Dragon it's been years since I've done anything lets just say I've recently escaped my prison and I want some entertainment more than I want immediate power.

"And what do I get if I win?" Spike asked the Sphinx waved him off.

"Since you will not be winning this I will be nice, Name your reward, and I will give it to you." Spike stared at her as he thought.

"Alright I cannot just tell her to leave; she will just head to the closest castle and start this up again." Spike tried to think of a solid plan to make sure she could not just do this again. Unfortunately, it didn’t make it easier for Spike considering what the Sphinx was currently wearing, he tried very hard to ignore her figure before giving into temptation and he shouted out.

"If I win You have to both marry and bed Me!" The look on Spikes’ face when he realized he'd actually just said that was only matched by the Sphinxes own shocked expression.

"I...I am sorry?" She asked, "Did you just...?"

"I did," Spike confirmed, the Sphinx went from confused to pissed.

"The fuck is wrong with you!? This was, is, a magical contract, If you win I am gonna be stuck with you for the rest of eternity!"

"Well sorry, but you just kind of threw me under the bus, and might I add that I am not the one in this room wearing a thong!" the Sphinx reared back at that.

"These clothes are traditional!"

"You are wearing underwear." Spike spat back, "Now throw your riddles at me and let us just get this over with."

"I have a mouth but do not speak, I have a bed but do not sleep, I run every were but go nowhere, what am I?" Spike blinked at her.

"You fucking kidding me? a River." The Sphinx growled at him as she thought of her next one.

"a six years old pony hammered a nail into his favorite tree to mark his height. Ten years later at age sixteen, he returned to see how much higher the nail was. If the tree grew by five centimeters each year, how much higher would the nail be?" Spike frowned at that one since it sounded to him more like a math problem than a Riddle.

"Um...50 centimeters?" Spike asked, the Spinx's smile told him he was wrong before she did.

"Wrong!" She laughed "The nail would be at the same height since trees grow at their tops." Spike's face palmed himself, silently calling himself a dumbass while the Sphinx laughed, "One for one, next one wins the whole shebang!" the Sphinx then asked Spike the hardest riddle she had

"A king has no sons, no daughters, and no queen. For this reason, he must decide who will take the throne after he dies. To do this, he decides that he will give all of the filly and colts of the kingdom a single seed. Whichever child has the largest, most beautiful plant will earn the throne; this being a metaphor for the kingdom. At the end of the contest, all of the little ones came to the palace with their large and beautiful plants in hand. After he looks at all of their pots, he finally decides that the little filly with an empty pot will be the next Queen. Why did he choose this little filly over all of the other children with their beautiful plants?" the Sphinx laughed herself silly for a second before she saw the look on Spike's face.

"Your gonna hate me for this." He said, "But I have heard this before." The Sphinxes eye's shot wide open.

"What! You lie! There is no way..."

"the reason he chose the filly is cause he only gave fake seed's and the filly was the only one honest who hadn't switched her's." with a loud rumble the Sphinx toppled over, the look of disbelief on her face somewhat funny to Spike as she stared at him, until she started crying, at that point Spike felt a little bad. Spike walked over to her and, quite awkwardly patted her muzzle.

"You...you wanna talk about it?" He asked, whatever her reply was Spike could not understand it through her crying, which was rapidly filling the room. Spike patted her muzzle one more time before she began shrinking, after a moment she stood at about 7 feet tall before falling to her knees to continue her crying. Spike, no longer sure how to solve this particular problem, walked over and hugged her, patting her lightly on the back as she cried into his neck. He was not sure how long this went on, but it was starting to get dark out by the time she calmed down enough to speak again.
"Alright." She said rubbing her eyes "ok, I made this deal, and I have to stick through to the end, Spike did not even have time to speak as the Sphinx stood up and picked him up like he weighed nothing. "Come then Dragon..."
"Name's Spike."
"Come then, Spike." She corrected "Let us go see if I am about to regret everything or if the universe has just rewarded me."
