A perfect fit

The store has no windows: you can't see in from outside. And to gain entrance you have to press a buzzer. As they wait to be admitted, she has a strong desire to run away. Sensing this, he takes hold of her hand, partly in reassurance, partly to keep her close.

Inside there are rows and rows of fetish clothing, in rubber, leather, latex. There's a long rack of paddles and whips, and an umbrella stand full of canes. There are gags of all descriptions, red and blue and yellow ball gags, gags like the bits that horses wear, gags with big penis-shaped plugs. There are wicked-looking clamps, for the nipples and maybe for even more tender parts. Restraints of all kinds are displayed for sale: hand-cuffs, neat little pairs of steel thumb-cuffs, leather cuffs for the wrists and ankles, spreader-bars to hold the legs apart. And then there are the butt plugs. Plugs in silicone and rubber and steel and glass, some so large she winces just to look at them.

An assistant approaches, a good-looking young man in a close-fitting black t-shirt. She isn't sure if he's gay, but she thinks he's attractive.

'Can I help?' he asks.

'I believe you have a personal fitting service for butt-plugs?' her dom says.

'Indeed we do, sir,' the assistant replies.

She blushes bright red. The assistant leads them into a small booth, drawing the curtain after them. There's a bench with a padded top.

'If madam would care to arrange herself?' the assistant says.

She hesitates. Her dom puts his hand on the back of her neck and steers her firmly to the bench, pushing her down over it. When she's in place, he lifts her skirt up to her waist. On his instruction, she isn't wearing any knickers that day. She blushes still more as she imagines the young man staring at her bare bottom. No doubt he's thinking, what sort of girl goes around with no knickers?

'First I'll do a measurement,' the young man says.

He produces a curious little device, a small tube split down the middle, the two halves joined by springs. At the end, attached to the handle, is a small dial.

'All our equipment and sample plugs have been carefully cleaned and sterilised,' he says.

He snaps on a pair of latex gloves, then takes a tube of lubricant and squirts some on his fingers. Gently he pushes a finger up into her ass. His touch is confident, assured. Even so, she is mortified to be spread out in front of a stranger and be invaded in this way. After removing his finger, he lubes up the device and inserts it. It's cold, but not uncomfortable. The assistant checks the reading on the dial.

'Squeeze,' he says.

Blushing still further, she contracts the muscles around the device.

'As I thought,' he says. 'She's not a big girl. She needs a plug at the lower end of the scale.'

He goes out. Her dom strokes the back of her neck. 'Good girl,' he says.

The assistant soon returns, carrying a tray with three black silicone butt-plugs, in ascending order of size. The first is reassuringly small. He lubes it up and quickly pushes it into her ass.

'You see how that one slipped in very easily,' he says. 'She can certainly takes a larger size.'

'Indeed she can,' says her dom.

The assistant pulls out the first plug and inserts the second. It feels notably larger, though still not uncomfortable.

'Perhaps a larger one still?' the assistant asks.

'Definitely,' says her dom.

The assistant carefully inserts the largest of the three plugs. She grunts as it goes in. She feels it stretching her, filling her. It's a good feeling, despite the embarrassment of a strange man performing such an intimate act. Her dom takes hold of the plug and turns it gently, then presses it in a little further. This is the one, she thinks. I feel really opened up, so aware of its presence.

'A good fit,' says the assistant.

'The thing is,' says her dom, 'she needs a really big one. If it's too comfortable it's not doing its job. Ideally it should hurt a little going in, so she is really being stretched to the limit. I'm training her to accommodate a really large cock.'

She cringes with shame. She wants the ground to open up.

'I see,' says the young man. He glances down at her dom’s crotch, as if to enquire, is the large cock in question yours, sir, or that of another gentleman?

Her dom ignores the implied question. 'Please bring me the next size up, and also the size after that,' he says.

She's left with the biggest of the three plugs still sticking in her ass. The assistant soon returns, with two plugs wrapped in cellophane.

'Should sir wish me to try them in her?' he asks.

'That won't be necessary,' says her dom firmly. 'I shall insert them myself once we are home.'

She turns her head and stares at the two plugs in the assistant's hands. The largest one is a terrifying size. No way will I ever takes such a thing, she says to herself. Quite impossible. It would split her in two. Even the smaller one looks scary. Her dom gives her a little smile, but it's not a look of reassurance, rather a 'just you wait till I get you home' sort of smile.

Deftly the assistant removes the plug from her bottom. He hands her a tissue to wipe herself. She gets gingerly to her feet, her skirt at last falling down and restoring her modesty. But she still can't look at the assistant for shame.

'Will there be anything else, sir?' the assistant asks.

'Not this time,' says her dom.

She can tell he's eager to get her home as soon as possible. Her bottom tingles at the thought, and she blushes once more as they leave the shop, the two enormous plugs safely stowed in his pocket.
