Tony groaned, curling into the sheets as he woke up to the Malibu sunlight streaming in through the windows. He'd never been a fan of mornings, especially when it was the weekend. Why should he have to wake up so early on Saturday and Sunday? It didn't seem fair to him.

"Good morning," purred a familiar female voice.

Squinting in the sunlight, Tony sat up, rubbing his eyes as he turned his head in the general direction of the voice. When he could see properly... his heart skipped a beat.

Pepper stood in the doorway, wearing some of the sexiest lingerie he'd ever seen in his damn life. Holy shit... Pepper goddamn Potts. There was a wicked smile on her face, and she couldn't help but let out a strangled giggle at his bemused expression.

"Pep-"

"Shh..." she hushed, walking over to the bed. The redhead climbed on top of him, straddling his hips. He continued to gaze at her in a mixture of surprise and awe, unable to believe that his normally tame girlfriend had become a fiery lioness before his very eyes. She pressed a finger to his lips, and chuckled.

"Happy birthday, Tony." she murmured hotly.

Yeah, this was gonna be a good day.
