Ellie couldn't stop thinking about her last encounter with Matt. She'd never have guessed he'd be into something like watching her pee, and what was even more surprising was how much she'd enjoyed it.
They hadn't spoken about the incident too much afterwards, at least not directly, but suddenly there was a nervous anticipation in the air. It was as if they were both just waiting for their next opportunity.
Ellie still wasn't completely sure how she felt about the fetish itself, but just thinking about Matt's reaction had her stomach fluttering and her panties dampening.
The way his cock stiffened as she'd opened her legs and relaxed. The near-animalistic manner in which he'd fucked her afterwards, both still covered in her urine. How dirty and naughty and sexy it all was... Yes, she knew exactly how she felt about that.
Their morning run was the obvious chance for round two, and Ellie wanted to be ready. She'd downed a couple of glasses of water before Matt was even out of bed, determined not to mess up her chance to perform for him.
-
Their run went smoothly - though it felt twice as long as usual. When Matt suggested they take a shortcut to cut off the last few bends, Ellie didn't think to question it, just as eager as he was to get back to their apartment.
Perhaps even more eager. When Matt made the suggestion, he could see in her face some of that same desperation from yesterday's shower.
As they paused to decide, her eyebrows were furrowed in concentration. Was she jogging on the spot to stay warmed up, or warding off the tickling sensation in her groin? Did she need to go already?
By the time they got to the door, Matt had his answer. As he searched for their keys, Ellie paced back and forth, stopping to cross her legs and bounce up and down.
He reached for the lock, trying unsuccessfully to slide the key inside.
"Oops, wrong one," Matt grinned back at her.
"Matt! Please, I'm practically bursting," Ellie whined, sliding her hand between her legs to grip her crotch tightly.
Matt unlocked the door and Ellie immediately squeezed past him into the apartment, sliding off her shoes and rapidly tiptoeing towards the bathroom with her legs together and that hand still pressed up against her shorts.
For a second, Matt thought he was about to see the door shut behind her. Then she called out, "Are you coming?"
He entered the room to see her already removing her bra, not wasting any time. There were those erect pink nipples again, surrounded now by visible goose bumps covering her soft white breasts.
Matt walked over and cupped a hand around one of them, whilst sliding his other hand across her cheek and through her hair, slightly damp with sweat from their exercise. He gripped a fistful and pulled her face into his, meeting her lips in a passionate open-mouthed kiss.
As he caressed her chest, thumb circling her areola, his tongue explored her mouth. She moaned as he found her tender nipple, squeezing it gently against his index finger.
For a few seconds, Matt's advances caused Ellie to forget the urgency of her situation. Then she felt another twitch between her legs, and realised a fraction too late that she'd let a few dribbles escape her.
She could feel the warm dampness spreading out in a patch on her panties, and she froze in horror.
This wasn't how it was supposed to go. During yesterday's encounter she'd been in control, a liberated woman choosing to fulfil her man's secret desires. Now she felt like a child after an accident.
