"Check it out!" Rainbow Dash grinned ear-to-ear as she threw open the door to the hotel suite.

"Oh! It sure is... red?" said Twilight, scrunching up her face as she stepped into the spacious room. "And why is there a jacuzzi in the middle of the bedroom?"

Rainbow Dash rolled her eyes and sauntered up to Twilight's side. She reached around her friend's withers and pulled her cheek-to-cheek.

"It's romantic. Like, duh," she said. "The bed's even shaped like a heart! Isn't that awesome?!"

"Ah, I get it. Yeah, that's pretty neat," Twilight said, with a wan smile.

Rainbow sighed, planted a hoof over her face, and shut the door behind her. "Twilight, you really need to chillax. I know being a princess is hard, but that's why we're here. You're so stressed, we never get to unwind."

"I know," said Twilight. "I'm just nervous..."

"Come on, sweetcheeks. Loosen up. Like this," said Rainbow Dash. She took Twilight's forehooves in both of hers, reared up, and shoved her onto the bed. Before Twilight knew what was happening, her friend lay atop her, muzzle to muzzle.

"Dash, I don't know if..."

"Shush. Less egghead, more gorgeous princess of my dreams," Rainbow Dash commanded, and planted a kiss on Twilight's trembling lips. Twilight shut her eyes tightly and parted her mouth. Dash was always so forceful, but at least she knew what to expect. After about half a minute of rough tongue, Rainbow Dash pulled up. Twilight quickly raised a hoof to block her lips.

Rainbow Dash panted, her eyes glazed over with lust. "You're so freaking hot. I can't help myself around you," she said. "You know I want to do you, like, every time I see you?"

Twilight smiled a soft but genuine smile. "I'm glad. I want to make you feel that way."

"You're amazing, hon. You always make me feel that way," said Dash.

Rainbow Dash leaned in for another kiss, but Twilight pulled her lips inward. A confused look crossed Dash's face. She began to lean in again, but planted the kiss on Twilight's forehead instead.

"This again," said Rainbow Dash, frowning.

"I... I'm still really stressed out," said Twilight. "I'm sorry."

Rainbow Dash rolled onto her back beside Twilight and sighed. "It's okay, Twi, I know you're trying. We just have to figure out what's wrong with you, and fix it."

Twilight sighed and stared up at the canopy. "I haven't felt like being intimate with anypony in a long time, Rainbow. I don't want you to think this is your fault..."

Rainbow snorted. "Well, of course it's not my fault, but it's not yours either. It's just, like, a monster we have to smash. I'm just frustrated because I'm always so horny around you," she said.

"Thanks..." said Twilight. "It's okay if you want to spend time with somepony else, though."

"I'm fine with the open rel, but I don't like cheating you, Twi. I want to marry you. I want it to be us, even if we never get to have sex again. That would suck, but it isn't what's important, y'know?"

"I know. I want that too, Dashie," said Twilight.  "I like waking up next to you, and growing together as ponies. But it's not cheating if I'm the one who suggests it. You and Applejack totally click, and AJ is my friend, too."

"Yeah, well... AJ's been a healthy outlet for me, but I don't love her like I love you," said Dash. "I just don't understand what the problem is," said Dash. "You like it when I take control; it's the only time you seem to get off."

"This is true," said Twilight.

"I don't get why it's so hard for you to be intimate with other ponies. I mean, I'm awesome, so it can't be me..."

Twilight turned on her side and looked at her friend's face. Dash looked very worried.

"Rainbow, it's okay."

"No, it isn't," said Rainbow Dash, and she turned on her side to face away from her friend.

Twilight reached around and hugged Dash close from behind, without saying a word.

"Twi... Do I turn you on?" asked Dash.

"Sure! Well, sometimes."

Rainbow Dash paused for a moment. "Sometimes?"

"It's complicated," said Twilight.  "There are some things I like, and some things I don't."

"Really?" said Rainbow Dash, her voice filled with surprise.

"Yeah."

Rainbow Dash paused. "This might sound weird, but... Twilight, could you teach me how to make you happy?" she asked.

Rainbow felt wetness against the back of her neck. Twilight was sniffling, and squeezing her tightly.

"Rainbow Dash, that's the most romantic thing I've ever heard."
