Bodies of different sizes

Every positions page on this site quietly assumes two mid-sized adults of roughly similar build, which describes a surprisingly small proportion of the people reading it. None of the safety guidance changes. Almost all of the staging does, and nobody writes that part down.

Consenting adults only. Everything on this page is about adults over 18 who have freely agreed to it.

Written from first-hand experience or extensive research by the editor.

I have written ten pages about where to put somebody, and every one of them assumes a pair of adults who are roughly the same size as each other and roughly the size of the furniture. That is a lazy default. It is also the reason a fair number of people read the positions section, conclude that none of it is built for them, and quietly close the tab.

So this is the missing page. Nothing here changes the anatomy: the fleshy lower half of the buttocks is the target whoever you are, and the never-strike list on where it is safe to strike applies without amendment. What changes is everything around it.

Over the knee, and when the physics will not cooperate

This is the position people ask about, and the honest answer is that it stops working long before anybody wants to admit it. A body across a pair of thighs has to be supported by those thighs, and if the person lying down is substantially larger than the person sitting, or simply longer in the torso, the whole arrangement becomes a balancing act that neither of you can hold for twenty minutes.

The variant worth knowing is kneeling. The receiver kneels on the floor beside a seated partner and lies across the lap from there, so the floor takes most of the weight and the thighs only take the hips. It is less enveloping and it works when the full version does not, particularly on a low sofa. Put a cushion under the knees.

If neither version cooperates, the thing to understand is what you are actually losing. The value of over the knee is not the geometry, which is poor, it is the constant contact and the sense of being held by somebody rather than arranged by them. That is available lying across a bed with your partner sitting beside you, one hand on your back throughout. Nobody will put that in a photograph, and it produces the same feeling.

Furniture that will actually take it

The practical heart of this page, and the part I would read twice.

A dining chair that is perfectly sound to sit on is a different proposition when somebody is braced over it and being pushed. Sitting loads a chair straight down through four legs. Leaning over the back loads two of them at an angle, and every stroke adds a shove. Old joints work loose, screws pull out of soft wood, and modern flat-pack chairs are built for the first case and not the second.

Before anything starts, have the person lean on it with their full weight while you push it firmly from behind and watch what moves. That test takes five seconds and it is on bent over a chair for everybody, but it stops being optional here.

Sofa arms are the other common disappointment. A firm arm is one of the best supports in the house. A soft one compresses under load, so the hips sink, the target flattens out and the pelvis ends up lower than the ribs, which is the opposite of what you want. A folded duvet along the arm fixes a lot of it. A sofa that was already sagging will not be fixed by anything.

Beds are the most reliable option and the one I would default to. A bed frame takes any weight two adults can put on it, the surface is continuous rather than balanced on an edge, and pillows let you build the angle you want rather than accepting whatever the furniture offers. See lying across a bed. If the frame is a cheap one, put the mattress on the floor rather than discovering the slats mid-scene.

Reach, angle and where the stroke lands

For the person delivering, a larger target changes the aim in a way that is easy to get wrong without noticing.

The natural landing point drifts. On a smaller frame the fleshy area sits where your arm wants to swing anyway. On a bigger one the safe zone is a wider band and it sits lower relative to the waist, so an unadjusted swing tends to creep upward towards the lower back and the kidneys, which is exactly where it must not go.

The correction is to move yourself rather than your aim: step back slightly, stand where you can see the whole area, and raise or lower the target with pillows so your arm travels level rather than downhill.

Reach matters too. If you cannot comfortably cover the far side without leaning across, you will end up working one side and finding a lopsided result afterwards. Move the person a few inches, or move yourself, rather than stretching.

Positions that tend to cooperate

Lying across a bed with pillows under the hips is the most adaptable thing available. It supports everything, the height is adjustable, and it can be held for as long as anybody wants.

Kneeling on a chair works well, with the same caveat about testing the chair and a cushion under the knees. So does over the arm of a sofa when the arm is firm enough.

The ones that get difficult are the deep folds. Touching toes asks for a range of motion at the hips that plenty of bodies do not have, and it is unforgiving about it. Bent over a table depends on the table being at the right height for that particular person, which is a lottery.

Anything held up by the arms for a long stretch is tiring in proportion to how much there is to hold up, so treat those as short punctuation rather than as the position for the evening.

Heat, breathing and comfort

Folded positions compress the chest and the abdomen, and that is more noticeable on a larger frame. The test I use is simple: if she cannot speak a full sentence comfortably in the position, the position is too folded, and a safe word she cannot say properly is not a safe word.

Heat is the other one. Bigger bodies warm up faster and shed it more slowly, so a room that was fine at the start becomes uncomfortable twenty minutes in. Open a window before you need to, keep water within reach, and treat somebody going quiet and flushed as information rather than as headspace.

Where size and joint pain overlap, which is common, the adjustments are the ones on chronic pain and disability rather than anything specific to this page.

Being looked at

I have included this because it goes unsaid, and because it is the real obstacle for a great many people rather than any of the furniture above.

Plenty of people carry years of practice at not being seen. Getting changed with the light off, holding a towel a particular way, choosing clothes by what they conceal. For somebody with that history, being undressed in front of another person is a far bigger ask than any implement, and the fear is not of the spanking at all.

If that is you, say so in the negotiation rather than hoping to manage it on the night. Staying partly dressed is a completely legitimate arrangement and always has been. So is low light, or a first session where nothing comes off at all.

And if you are the other person: notice how much that disclosure cost, do not make a speech about it, and simply behave as though it was ordinary. The reassurance people want is not a compliment. It is being treated as unremarkable.
