especially when she gave me the tiniest little smile, a secret between us.
‘Thank you, ma’am,’ she said.
‘Now,’ said the boss, ‘bring me the plug and then undress yourself, for Kim to watch.’
Mara handed over the item, which I saw was a butt plug, quite a wide model, not for beginners. Then she came to stand opposite me, so close I could touch her, but I wasn’t sure it was allowed, so I held off.
She unbuttoned her shirt and slipped it off, then took off her bra to reveal beautiful full, plump breasts with round red nipples.
‘Touch them, Kim,’ invited the boss. ‘Feel how heavy they are.’
They were rather heavy, not the weightiest I’d ever held, but certainly filling my palms satisfyingly. I let them jiggle in my hands, then I squeezed them, then I stroked the nipples with my thumbs and was rewarded with a pretty little shimmy of her hips.
‘She has very sensitive nipples,’ he remarked. ‘The lightest of clamps is all she needs. But I’m not going to clamp them today. She’s had her quota of pain. Feel how hot her bottom is.’
I slid my hand around her hip, on to the luscious curve of her arse. Oh, he was right. The heat was lovely, like warming my hands on a radiator. I loved the effect the strap had made, ridging her skin so I felt little ripples of sensation when I stroked it.
‘Best of all,’ said the boss, more softly now, ‘is the effect a good thrashing has on her pussy. Touch it. You’ll see.’
I looked up at her face, as if seeking permission, but her eyes were closed in a kind of rapture. She was somewhere deep inside herself but, wherever she was, it was exactly where she wanted to be.
I parted her thighs a little wider and dipped two fingers between her pussy lips. So hot and juicy, and her clit was swollen right up. I massaged it slowly, enjoying the way her thighs trembled against my hand.
‘You’re right,’ I said to the boss. ‘She’s soaking wet.’
I pushed my fingers into her cunt, digging inside, feeling her tightness, while I kept my thumb on her clit.
‘Hmm, careful there, Kim, you’ll make her come. She’s not to come yet.’ He changed the subject brightly. ‘Have you any experience with butt plugs?’
‘A little,’ I said. ‘Not much.’
‘But some? Oh, I’m sure you’ll do a good job.’
He sat down on the edge of the bed and unbuttoned his trousers. ‘Over here, Mara, on your knees.’
She knelt between his legs, waiting obediently while he removed his erect cock from his underpants.
‘She’s going to suck my cock while you put the plug in,’ said the boss. ‘Lubricant is in the right-hand drawer. Let me know when it’s fully inserted.’
I blinked, a little nonplussed at the turn of events, but I retrieved the bottle of lube and went to sit on my heels behind Mara, who by now had a good mouthful of the boss’s rather large cock.
I parted her buttocks, seeking the tiny round hole I had the task of filling. Her cheeks were hot and obviously still sore, and her little rosebud quivered when I pressed my thumb against it. She was obviously well trained, though, because she kept her bum thrust out and didn’t try to clench or wriggle away from me.
I uncapped the lube and spread plenty on my fingertips, then I pushed them against the rosette, circling it delicately, getting closer and closer to the target. I felt a tiny pressure of resistance, then my forefinger eased inside. How tight she was. I thought she might suck my finger inside and hold it there, but I was able to pull it back with little trouble.
I applied a good squirt of lube to the plug and went to work on that next. I pushed it slowly and gently, rotating it until it began to slip in. As I pressed, then stopped, then pressed some more, she made scoffing noises, her mouth too stuffed to express her real reaction.
The boss was holding her by her hair, keeping her head low down. I wondered if she was deep-throating him. He looked pretty happy, at any event.
‘How … is it going?’ he rasped.
‘Nearly halfway in,’ I reported. ‘Just getting to that nice wide part.’
‘Keep that held there for as long as you can before you push in the rest,’ commanded the boss. ‘Make her feel it. Make sure she really feels how full and stretched she is.’
‘You’re the boss,’ I said. ‘Now, keep still, Mara, and be a good girl. You’re going to have a sore bum, but you won’t mind, will you? Because it’s what you deserve.’
I loved her little gasps of shock and amazement as I held the plug at the cruellest part. The boss shoved down hard on her head, fucking her mouth. She writhed at the hips and I took pity on her and pushed it all the way in, so that the flange sat between her cheeks, showing anyone who looked that her rear hole was occupied. How decadent it looked, with her striped scarlet bum cheeks on either side.
I wanted to touch myself again, but I knew better things were coming, so I held off.
‘Good,’ said the boss. ‘Off, Mara.’
He let go of her hair and released her mouth from his thrusting cock.
‘Now then, Kim, it’s up to you what you want to do with your clothes, but you need to lie down on the bed with your legs spread and your cunt available for Mara to lick. I’ll give you a moment …’
It barely took a moment. I threw myself eagerly on to the bed, pulled up my skirt, yanked off my knickers, layingmyself bare for Mara’s tongue.
Soon enough it was there, planted between my lips, while she breathed and stroked and licked like an expert, kissing my clit and pushing her fingers inside my cunt with such absorption that you would never realise she was getting fucked from behind all the while. Her face lay buried in the junction of my legs, building my arousal higher and higher, while the boss, still almost fully clothed, rose behind her like a giant, his tie flapping this way and that, his cheeks growing redder, his veins beginning to stand out on his forehead.
I was the first to come, melting blissfully into that hot, eager mouth. She didn’t withdraw her tongue, but kept on kissing my spread lips until she moaned into them, her own orgasm forced from her by the boss’s purposeful thrusts.
He held on a while longer, seeming to enjoy his view enough to want to prolong it, but eventually he too joined us in our post-coital haze, collapsing on top of Mara’s back with a roar.
‘Well, Kim,’ he said, once he had Mara over his lap to remove the plug. ‘Thank you so much for your input, but I hope we haven’t kept you from your duties.’
Oh. My duties. I should have finished polishing the silver in the drawing room ages ago.
‘Oh, right,’ I said, looking from him to her.
Mara smiled at me with lazy satiety. ‘That was awesome,’ she drawled. ‘We’ll come here again.’
‘I hope you do,’ I said, smoothing
