Can you really say "no" to a Princess?

White Lighting returns to the palace with Twilight in tow and opens the door expecting Celestia to blast him to tartarus with her magic, but no pony is waiting for them.

"We're back", he yelled out, but no pony responded. "Heh, night shift. Guards are probably all down in the recreation rooms not doing their jobs. I should have a chat with Luna about that, seeing how she lets them do that."

He heads to one of the empty royal suites and puts Twilight down in bed. He makes his way to the door to head to the kitchen to get her some water when she calls for him.

"Hey Flash", Twilight said with a tired tone.

"Yes Princess?", he replied.

"Heh, I told you stop calling me that. My name is Twilight Sparkle", she said rolling over on her back.

"I can't do that. As I have already said", he replied starting to walk out of the room again.

He was almost out of the room when he heard the words he never thought he would have ever heard uttered from Twilight's lips of all ponies.

"Fuck me Flash", Twilight said looking at him.

He froze in disbelief of what he just heard. He stood there processing what just happened and turned around to look at her. She was licking her lips and looking at him coyly with begging eyes.

"Excuse me?", he said in disbelief.

"I said, Fuck...me...Flash", Twilight responded slightly annoyed.

"Yeah, um, not going to happen. One, you are drunk. Two, Celestia would castrate me. And three, I shouldn't have sex with the ponies I'm supposed to protect", he replied sternly.

He turned around and was about to leave the room when Twilight decided to dig into his core beliefs as a pegasus.

"If you leave this room you will be backing down from a challenge. How many pegasi get to say they had a chance to outlast an alicorn in bed? And how many can say they have?", she said slyly hoping for a reaction knowing he will defend his pegasus heritage to the death.

He stood there thinking about what she just said to him as he tries to maintain his composure.

"Don't give in Whitey. Don't you fucking dare do it. What honor is there in taking advantage of a drunk pony that isn't thinking straight", he thinks to himself fighting the urge to respond to her taunts.

"Huh, I though you were White Lightning, Captain of the Royal Guard. Seems to me I'm looking at a scared little colt", Twilight taunted him even more.

That scared little colt statement sent Whitey off the edge. He was not going to let some stuck up Princess talk about him like that. He turned around and looked right at her.

"Looks like I hit a nerve", Twilight said sarcastically as she laughed.

Whitey walked over to the bed grabbed her back legs, spread them out and rammed his dick into her balls deep as she screamed and arched her back from the force. He commenced to thrust her over and over going balls deep each time. His dick got harder and harder till with each thrust her stomach bulged a little.

"Oh...Celes...tia...this...is...fuck...ing...ama...zing...don't...stop...show...me...that...pega...sus...power", Twilight uttered with each of his thrusts.

Whitey began to speed up as Twilight's wings began to curl up from the pleasure over taking her body. She picked her head up and looked at Whitey who was smirking at her.

"You asked for this Twilight. I hope you can just survive it." Whitey said as he sped up even more.

Her pussy was now gushing juice out around his dick every time he thrust it deeper into her. The bed was beginning to become soaked in her juices as if his dick had broken a dam inside her.

Her moans of pleasure and her heavy breathing only intensified Whitey's resolve to teach her a lesson. He knew she was never going to forget this night as he was planning to do his special technique on her.

Her wings and legs began to spread out and magic sparks came out of her horn as she reached her climax and screamed at the top of her lungs in ecstasy. When she climaxed there was a burst of magic energy from her horn that emitted this incredibly bright white light.

Whitey stopped his thrusting and grabbed her plot and turned her over on her stomach and began fucking her again. She grabbed at the bed covers trying to get a hold of something as the thrusting was violently shaking her body. Whitey leaned forward and bit down on her mane and pulled her head back and held her there.

"More...give...me...more", she said with every breath.

At this point there was so much of Twilight's juices on the floor they were forming a puddle and the bed was soaking wet. While fucking her Whitey got an idea. He sped up and when he pulled back he pulled out completely and slammed his rock hard dick right up her plothole.

"SURPRISE! Plotsex!", he yelled out.

As soon as he rammed his dick up her plothole she screamed in pain as she tightened up around his dick and her eyes went derpy as she bit her lower lip. He let go of her mane and she flopped back down on the bed. She turned her head and her tongue was sticking out as she salivated on the bed. He fucked her in her plothole for a while till she started to bleed a little.

Whitey pulled out of her plot and slammed it back inside her pussy as juices squirted out around his dick. He decided that enough was enough and she learned her lesson as she was now losing consciousness from the overload of pleasure. He grabbed a hold of her plot and started to speed up even faster.

"You might want to brace yourself Twilight", he said slyly.

He continued to speed up faster and faster and she grabbed at the bed bracing for whatever is about to happen.

"B-blow y-your l-load i-insi-ide m-me W-whitey. I-i w-want a-all of i-it i-insi-ide m-me", she said as the vibration of his thrusting shook her body.

Whitey's speed was so fast his body didn't even look like it was moving. Twilight only felt vigorous vibrations in her as Whitey continued to speed up. Her eyes rolled back into her head from the pleasure. He grabbed her tighter as he was about to blow. He was fucking her so fast that when he hit his climax he broke the sonic rainboom barrier with his hips and blasted his load inside her while rainbows flowed out of her pussy around his dick followed by his seed oozing out as he continued to cum for a whole minute.

He pulled his dick out of her as juices gushed from her pussy and she slumped down on the bed panting as her body shook from the pleasure flowing through her. Her legs and wings twitched uncontrollably and her horn spurted out sparks continuously.

He walked over to the other side of the bed and crawled into it and laid down and kissed her as she raises her twitching hooves to grab his face and kiss him back. They kiss for minutes before breaking it.

"You know. I don't think it would be so bad to be in a relationship with a pony I'm supposed to protect", Whitey said looking at Twilight with carrying eyes. "Well, that is if she wants to be my marefriend."

"How can I say no to a pegasus like you", Twilight replied grabbing his face to bring him in for another kiss.
