Now the conservatory door was opening and she could hear him stepping onto the decking as she collapsed back down onto the lounger, her fingers still inside herself, twitching and pulsing.

‘Em, you okay? You asleep?’

‘Huh?’ she managed, her chest still shaking from the orgasm. Her lips were dry and she was breathing erratically. She rolled away sideways and slid her hand back out of her skirt, smoothing herself down and trying to catch her breath.

‘No, just dozing,’ she said, her whole body still throbbing. ‘Could you put the kettle on?’

‘Sure,’ he said, turning back towards the kitchen and buying her a few more seconds to recover.

‘How was your day?’ she asked as he came back and stood beside her, leaning down to kiss her glistening forehead as the low whistle of the boiling water began to build.

‘Interesting. James handed in his notice.’

‘Oh.’

‘Yeah, he’s moving over to Integen,’ he said, sitting down on the lounger next to hers. ‘Tom’s putting him on gardening leave.’

‘When he’s going?’

’Two weeks.’

‘But that’s before-‘

‘Yeah I know,’ he raised his eyebrows in dismay and lay back. ‘You okay? You’re sweating.’

‘I'm fine, just a little warm.’

‘How was your shift?’

‘Good, I had a nice old man with a hip dislocation who was telling me all about his wife and his mistresses, that was very entertaining,’ she said, taking a deep, uneven breath. ‘And a pretty young girl who works on a cruise ship as a singer and she had a few interesting stories to tell. People are very naughty on cruise ships. She was telling me that there are whole cruises for swingers.’

‘Oh, really?’ said Cassian.

‘Yep, she worked on one for six months. She got quite used to turning down invitations from older couples to join them in their cabins.’

‘Oh,’ said Cassian, smiling.

‘Sounded quite exciting to me,’ said Emilia. ‘Other than that, it was a quiet day. Although the MRI scanner broke down, so that’s going to create a backlog for a few days.’

‘That’s a shame,’ said Cassian.

He leaned forward, drew off his tie and unbuttoned his shirt.

Emilia’s heart rate fastened and she felt a familiar and urgent feeling of desire in the pit of her stomach and between her legs. Her husband’s physique was toned, to put it mildly. He ran ten kilometres four times a week, lifted weights, and cycled to work most days at a shared office in the city centre and during lunch he went to the gym.

Her sister, Alice referred to Cassian as The Greek, and Emilia had often wondered if his past hid some middle eastern ancestry with his olive skin and thick dark hair. For a whole summer a few years ago she had buried herself in discovering their shared family histories but she had hit a roadblock around one hundred and fifty years ago on his side and had eventually lost interest, telling herself she would pick it up again one day.

She couldn’t help herself around him though, ever since they’d met, all those years ago, they had been unable to keep their hands off each other, and although she naturally worried that one day their mutual attraction might falter, she didn’t see it happening any time soon. Fantasies about fictional men and swinging cruise ships aside. Besides, right now she was feeling horny, courageous and very, very kinky.

She stood up, letting her skirt settle down around her thighs and tip-toed softly across the warm wooden slats of the decking, letting the strap of her top fall off her shoulder to her elbow and exposing her breast. Then quickly and quietly she stepped over her husband and lowered herself down, straddling his legs and unfastening his belt. Before he knew what was happening, she was pulling his trousers down and sliding up and over him, pulling her still wet underwear to one side.

‘Em, what are you-’ he managed to say before Emilia placed a finger over his lips as his eyes widened.

As she knelt up, she felt him surge and grow beneath her, teasing her lips, then she slipped down onto him and sighed.

They had showered after making love in the garden, drying each other and kissing and cuddling as they made their way into their bedroom, and now Emilia was laid out flat on their bed, her silk gown draped beneath her as a gentle breeze from the open window teased out goose-pimples across her skin. Her toes curled as Cassian’s hands slid down her spine and kneaded the skin above her bum, pressing his fingers deep into the small of her back as she elicited a gentle moan.
