A/N: So I was watching an episode of 'How I Met Your Mother' and in it Lilly was wearing a short lace nightie and it made me think back to Iron Man 3 and how Pepper was just wearing a t-shirt and a pair shorts, so this was born.

Oh and side note, Pepper is not currently living with Tony, just staying the night.

"What is that?"

Pepper freezes as she exists the master bathroom, eyebrows knitted together in confusion as Tony's gaze sifts along the length of her body. Looking down her confusion only grows as her eyes scan the graphic tee she wears for bed along with a pair of sweat shorts; nothing abnormal catches her eye.

"What?" she asks, slightly defensive.

"Seriously?" Tony asks, pulling a face. "That's what you wear to bed?"

Pepper glances back down at her self, before looking back up at him, folding her arms over her chest "What else would I wear to bed?"

"Something sexy." He offers, like it should be obvious. "And sheer," he adds with a grin.

Pepper rolls her eyes and moves towards him, "You think I lounge around in lingerie in my apartment?"

"Well not anymore," Tony snorts as he gestures towards her. "You kinda shot that in the face."

"Glad I could bring you back to reality," Pepper offers cheekily, moving past him and towards the bed.

She fails to see the small smile that forms on his face as she walks away. In truth it doesn't bother him, really it's more surprise, he use to the playboy bunnies and skimpy underwear. The truth is he likes that she doesn't feel the need to try and impress him, it's all vastly different from what she presents to the public. Gucci and Prada are traded for cut off jean shorts and simple t-shirts when they're in private. In short she's nothing like other girls he's been with, with some spending more on underwear than he has cars. Still, he enjoys poking fun at her.

"What part of that screams, 'I'm ready.'"

"I doesn't," Pepper supplies without missing a beat as she settles down in bed. "It says 'I'm going to bed and I want to be comfortable'."

"Comfortable," Tony snorts as he moves to his side of the bed, settling in next to her. "Talk about killing a boner."

Pepper shakes her head slightly with a small smirk, leaning across the space between them to cup the side of his face. "I'm not wearing any underwear," she whispers in his ear before pulling away.

"I love you," Tony chuckles with a large grin, leaning and pressing his lips to hers,

A/N: No idea how to end this, sorry guys, anyway, please review :)
