Impact is a language. Implements are its dialects. The message is structure, not spectacle: predictable dose, controlled geometry, and outcomes that match intent. Authority is proven by precision and repair.

• Surface area: wider spreads sensation and reduces penetration; narrow concentrates force and increases sting.
• Mass & speed: heavier tools favor thud (deep pressure); faster lighter tools favor sting (surface burn). Balance to plan the nervous system response.
• Flex: flexible tools (canes, straps) store energy and release late; rigid tools (paddles, blocks) deliver on contact.
• Edge profile: radiused edges are safer; sharp transitions concentrate stress and mark unpredictably.
• Handle & balance: grip security and center-of-mass control repeatability.

Standard: If you can’t predict the response at a given distance and tempo, you are not ready to escalate.

Paddles (rigid; wood/leather): dependable planes for dose control. Choose radiused edges, balanced handles. Species: zebrawood, bloodwood, Cuban mahogany deliver distinct weight and feel—select for outcome, not vanity.

Canes (flex; rattan/wood composites): precise, high-contrast lines. Use measured arcs; avoid joint lines; never whip without a predictable landing zone.

Straps/Belts (wide flex): distribute load; watch wrap-around. Keep angles shallow; avoid edge bite.

Crops (tip-focus): small surface, high sting. Reserve for clear targets, never at joints or nerve paths.

Leather wraps / sleeves: soften bite, add grip, and protect edges. Sanitize and condition routinely.

• Inspection: check faces, edges, glue lines, finish; retire cracked or delaminated tools.
• Sanitation: clean non-porous surfaces; quarantine and retire damaged leather that cannot be sanitized safely.

• Prefer: gluteal mass, posterior thighs (lateral), upper back (fleshy areas only).
• Avoid: kidneys, spine, joints, tailbone, hip points, knees, elbows, back of the neck, and any area marked “healing.”
• Angle: strike perpendicular to surface to avoid wrap; manage rebound path.
• Cue signs: color, breath cadence, muscular guarding, dissociation; adjust on evidence, not on guess.

Standard: The safest strike is the one you can describe and reproduce.

• Warmup: progressive, even coverage; build perfusion before contrast.
• Cadence: set a metronome pace; hold plateaus 30–60 seconds to read the system.
• Spacing: rotate zones to avoid stacking bruises; allow recovery within the scene.
• Counting: you count; they breathe. Counting is a control surface, not a game.
• Ceilings: pre-agreed intensity/time caps. When reached, you close or re-consent—never freelance.

• Classification: warmth/redness → transient; patterned bruising → moderate; deep swelling/discoloration → stop and reassess.
• Immediate care: cloth-wrapped cooling 10–15 min; elevate when useful; no heat on heavy impact for 24h.
• Aftercare handoff: breath pacing, warmth layering, hydration/electrolytes. Document what restored fastest.
• Follow-up: T+12/T+24/T+72 cadence to confirm recovery and update ceilings.

Education here is not medical advice. Seek qualified care when necessary.

• Pre-brief: purpose, implements in play, ceilings, non-targets, signals.
• Active consent: re-check at escalation points and position changes.
• Audit: post-scene five questions—truth, edge, signal, care, future. Record outcomes in the Ledger.
• Repair speed: if impact diverges from agreement, you state it, repair it, and verify it.

Stop and evaluate if you observe: sudden numbness/weakness, sharp or electric pain, unusual swelling, abnormal color/temperature that doesn’t normalize, disorientation, breathing distress.

• Stop → stabilize → cool/warm as appropriate.
• Assess orientation and distal motor/sensation.
• Escalate to professional care when in doubt; document implements, sites, and timing.

Dominant Standards

• Implements inspected, edges safe, balance proven.
• Cadence and dose are deliberate and repeatable.
• Signals enforced; ambiguity treated as pause.
• Ledger updated; ceilings adjusted by evidence.
• Repairs owned and verified.

Partner Standards

• Report sensation truthfully and early.
• Use signals exactly as negotiated.
• Track recovery, hydration, and sleep; bring data to the audit.

Calibration Set (10 strikes)

1. Five light, distributed—read color and breath.
2. Three medium to target—confirm cadence and angle.
3. Two at ceiling minus one—verify consent to proceed or hold.

Pre-Impact Brief (60 seconds)

1. Purpose & outcome (lesson, ritual, restoration).
2. Implements & non-targets.
3. Signals (verbal + nonverbal) and stop rule.
4. Follow-up time set now.

Closing Script

“We end with order. Breathe with me. Cooling now. You are safe; we are complete. Recovery cadence is set.”

Impact without structure is noise. Implements without audit are props. Here, contact is a contract: designed, delivered, and documented.

Not Kink. Discipline.
