“I am so sorry for being late, Rarity!” Purple mare hurriedly ran to her friend Rarity.

“That’s okay, darling…” she glanced at Twilight, who dressed very fancy, and her dark circles. “Just a tea party, no need for dressing fabulous, I didn’t invite anypony else. Em, you didn’t sleep well last night, did you?”  

“I do? I didn’t wear…” Twilight looked herself, Oh well! I do wear fabulous! Hmm, probably I was a little dizzy when I got up, maybe I should drink some coffee.

“Twilight, you really should have a good sleep, how about delaying our tea party?”

“Eh? No! You don’t have to, I am okay, I can participate!” Twilight smiled to her.

“Really?” The white unicorn brushed her messy bangs a little.

“Of course, let’s go, Rarity!” Twilight vigorously pulled her friend, pretending she’s pretty awake.

“Hello there! Afternoon, Rarity!” Flash accidentally saw the twos at the corridor.

“Same to you, Flash.” The white mare greeted him politely, but Twilight groaned secretly. Ah! Here goes my nosy husband! Hope he won’t embarrass me.

“And afternoon to my cute baby~” Flash kissed his princess’ cheek fondly, who blushed.

“Your dress is so beautiful, Babe, where are you two going?” He nuzzled at her lovely.

“Oh, we have a tea party at my boutique.” Rarity answered him.

“Well then, have fun! By the way, Princess, have you seen my-hold on, your underwear is falling. Here, let me help you.” Orange pegasus gently grab it with his muzzle.

“Hmm?” Twilight turned around, seeing her husband helping her.

“What a gentlecolt! Twilight, you are very lucky to have a helpful husband!” Rarity was happy to her.

“Oh, hehe…well…thanks…” Yeah, always does “helpful” things to embarrass me!!

“Wait a minute, THAT’S my underwear! I’ve been searching it for several hours, no wonder I couldn’t find it! It’s on your booty!” Flash was surprised by his finding.

“What?! That’s nonsense! I never wore your…” She turned around again, she panicked. It is his underwear! But-but how? I never did this thing! Maybe…She remembered that she awoke from her noon nap, she dizzily remembered she had a little invitation to Rarity’s tea party this afternoon, so she hastily put on her clothes (though she knew she didn’t have to when she’s sane), and grabbed random underwear. At first, she felt that pants was too big for her, because there’s a small bag at the groin, she thought she lost her weight, now she realized that it belongs to her husband, and the small bag was for his…eh, she grimaced. I knew I should drink more coffee!

“It is?!” The white unicorn gasped. No! Stop! Rarity!

“Of course it is! See!” Flash pulled up the pants with his teeth.

“Ah! Put me down! Do you want everypony know your underwear?!” Twilight yelped in a huff.

“Wow, it is!”

“Tsk, tsk, tsk! Princess Twilight Sparkle, I thought we should be honest with each other, you never told me you had a…strange habit! Stealing my underwear and wearing it on your booty.” Flash shook his head “angrily”.

“No! I didn’t steal it, okay? I…I…I just accidentally wore your pants!” Her cheeks reddened like a tomato. Shut up, Flash! Did I look like a weirdo that steal your things?

“Oh~that’s interesting! I wonder what will happen next…” Rarity watched the scenes intensely.

“Baby, did Applejack told you that lying is wrong?” He seriously stared at her.

“I…I didn’t lie to you! I didn’t steal your underwear! I…I swear!” Purple mare shouted at him, hopping up and down, her cheeks already burned like fire.

“Oh, really?” Stallion stared at her calmly, crossed his arms around his chest, “then why are you stammering? And why did you shout at me? Hmm?”  

“I…I don’t know, it’s…em…” If you didn’t embarrass me, I wouldn’t do that!

“Tsk, tsk, tsk! See? You ARE lying! When I was searching my pants in the morning, I did open your wardrobe to see if it’s in there. You didn’t want me to discover your little secret, so you wore it on your booty in order to not being caught, didn’t you?”

“What?! Shut up! I…I…”

He signed.

“Never mind, I guess you like my underwear, that’s why you stole it without my permission, besides I ain’t selfish, I’m pretty “open-minded”, so I handsomely lend it to you, remember to give it back, okay?” Flash kissed her on her muzzle.

“Ha?” Twilight confused about the result.

“Remember, Baby, love me but don’t love my underwear.”

“Wha-? Stop…” She was interrupted by his kiss.

“Shush, Baby, don’t say a word.” Pegasus pulled out the kiss, fondly staring at her purple eyes, she instinctively silenced.

“Good, now have fun with your friend! And go home early, because I will make your favorite food tonight!” After last kiss, he left.

“Ah, I don’t have to worry about my pants! You know I should ask you earlier…” His voice trailed off.

Eh!! He finally left! Twilight looked at Rarity, who smiled at her “creepily”.

“Well what are you looking at?!” She hotly said.

“No, nothing, darling.”

Princess turned around to her room.

“Twilight, where are you going?”

“Take off my dress of course! And his disgusting underwear!!”
