Impact play basics: tools, targets, and warm-ups

Where it's reasonably safe to hit

There's an old educator's phrase: "hit where there's meat." Soft, muscular, padded areas with no underlying organ, kidney, or major nerve. Specifically:

• The fleshy part of the buttocks (not the tailbone, not the top of the hips).
• The upper thighs (back, not inner).
• The upper back, between the shoulder blades and the spine — carefully.
• The chest, away from the sternum (with caution and explicit consent).

Where it is not safe to hit

• Kidneys (lower back, sides). Striking here can cause real injury.
• Spine. Any direct hit on the spine.
• Tailbone. Painful for the wrong reasons and easy to bruise badly.
• Neck and throat.
• Joints — knees, elbows, hips.
• Face — unless explicitly negotiated, slow, and with care; never a closed fist.
• Breasts and genitals — possible with experience, but a separate, more careful conversation.

Tools, roughly from gentlest to most intense

1. Bare hand — actually one of the best teaching tools; you feel exactly what you're doing.
2. Floggers — wide and thuddy, easier to land safely.
3. Paddles — concentrate force into a smaller area; respect them.
4. Crops — stingy and precise; small landing zone.
5. Canes — high skill ceiling, easy to draw blood; not a beginner tool.

Warm-up, every time

Skin and muscle that's been warmed up gradually can take much more intensity than cold skin. A useful arc for a 20-minute session:

• First 5 minutes: light touch, slaps, broad-hand warm-up.
• Next 10 minutes: build up gradually, checking in every minute or two.
• Last 5 minutes: peak intensity, then taper back down.

Skipping warm-up is how you get bruises in the wrong places and a partner whose nervous system never quite came along for the ride.

Reading the body

Things to watch for in the person receiving:

• Breathing — deepening is good; shallow or held is a yellow flag.
• Muscle tone — softening into it is good; flinching away or going rigid is a yellow flag.
• Vocalisation — sounds, even loud ones, are usually fine. Silence after they'd been vocal is a yellow flag.
• Skin — pink and warm is fine; bright red is approaching enough; broken skin or rapid bruising is past enough.

Aftercare for impact

• Cool down with broad, soft touch on the same area.
• Arnica cream or a cool pack for bruising.
• Hydrate. Eat something with sugar — the adrenaline crash hits in 15–30 minutes.
• Soft warm clothing and a quiet space.
• Check in again at 24 and 48 hours.
