I really liked the Smut Marathon 2019 Round 5 prompt, so I had a go at using it myself…

Moth

They’ve turned off the light because of the moth. They don’t usually fuck in the dark, but it seems the only way when it keeps flying headlong into the lightbulb. Plus, it’s so big that Emma pauses halfway through unbuttoning Johnny’s jeans to reach for her phone and google ‘Huge moth UK what?’

‘Sorry, were we not busy?’ Johnny asks.

‘It’s massive!’

‘I’m massive!’ He gestures at his crotch.

He has a point – the dark denim is bulging with the thick heft of his cock.

Still, Emma won’t give him the satisfaction. ‘That’s debatable,’ she teases, straddling him as he flicks off the lamp, plunging them into blackness. ‘Impressive, but not worth googling.’

‘Bit harsh,’ he says. ‘How would you feel if I said similar about your tits?’

‘Ah, but we both know my tits are massive,’ she says. ‘You can’t deny they’re equal to that moth in terms of impressiveness.’

‘Shh,’ he mutters, shoving his jeans and pants down and pushing inside her.

‘Say it,’ she persists. ‘Tell me they’re impressive.’

‘Fine,’ he says. ‘They’re impressive. Can we fuck now?’

‘Are they the most impressive you’ve seen?’

‘Emma! Seriously!’

Even in the darkness, he can tell she’s grinning madly. It’s a big part of what makes their dynamic work, these constant attempts to wind each other up. He shoves two fingers into her mouth, feels her laughing around them.

‘Shut up and let me concentrate.’

Instead, she bites down playfully.

‘Can’t you just suck them like a good girl?’

Her teeth sink in a little deeper.

‘Right, that’s it.’ He withdraws, so only the tip of his cock is still inside her.

‘I thought you said you were massive,’ she says, her words garbled by his fingers. ‘I can barely feel you.’

He shakes his head, despairing, then pulls his fingers free and uses both hands to pin her arms above her head while he thrusts into her hard and fast.

‘Better?’

‘Better.’

‘You,’ he says, ‘are a fucking nightmare.’

More laughter. Johnny thinks he might prefer the sound of her laughter to the noises she makes when she comes, but when she does he decides he can’t choose between the two.

Afterwards, she barely lets him catch his breath.

‘Catch the moth before you go?’

‘You scared, Em?’

‘Nope, just hoping for some actual benefits with this friendship.’

Johnny sighs, and heads downstairs to fetch a glass.
