Work Text:
It had started with a case, as everything did.
A murder staged to look like autoerotic asphyxiation, but the rope work told a different story.
Sherlock had studied the knots, the precise positioning, the attention to circulation that spoke of practiced hands, not the fumbling desperation the killer wanted police to believe.
The investigation led him down rabbit holes of research, and research led to curiosity, and curiosity led to a message board on FetLife at three in the morning with a cup of tea growing cold beside his laptop.
Experienced dom seeks intelligent sub for occasional sessions. Discretion assured. Proper protocols observed.
John’s profile had been sparse but compelling: medical background, impeccable references, a no-nonsense approach that appealed to Sherlock’s methodical nature.
They’d exchanged messages, negotiated boundaries, signed contracts with the thoroughness of diplomatic treaties.
Sherlock had expected professionalism. He’d prepared for physical intensity. He hadn’t anticipated this—the gentle insistence that he remain still, the careful monitoring, the way a stranger refused to leave him alone in his vulnerability.
Reality felt distant now, as if perceived through thick fog. His limbs felt heavy, pooling like liquid mercury over the impossible softness of the Egyptian cotton bedsheets in the boutique hotel he’d reserved for the session. His pulse hammered a steady rhythm in his ears—not frantic, but deep and resonant, like the Grand Organ at Albert Hall, which always, always, reminded him of the deepest blue, the colour the profoundest emotion manifested in his Mind Palace.
This was the fall.
He’d studied it clinically, cataloging the physiological responses, memorizing the neurochemical cascade.
That knowledge proved useless now.
Reality had narrowed to sensation: the whisper of breath across his nape, the delicious smarting on his glutes, the phantom echoes of restraint tingling on his wrists, the semen crusting on his pubes.
“Easy” John’s voice drifted from somewhere above. “You’re safe”.
Safe.
The word bounced around Sherlock’s skull like a marble in an empty jar.
When had he last felt truly safe? Not merely protected by his reputation or intellect, but genuinely, completely secure? His analytical mind tried to engage, to dissect this unusual vulnerability, but thoughts moved like treacle.
Fingers carded through his hair. Steady, repetitive, hypnotic. The gesture pulled him deeper into his body, away from the buzzing static that usually filled his head. No cases demanded attention. No texts required answering. Nothing mattered but his body.
“Chocolate”, John murmured, and something sweet pressed against Sherlock’s lips. He accepted it automatically. Dark chocolate—seventy percent cocoa, Madagascar vanilla, a hint of sea salt. His palate catalogued details while his conscious mind drifted.
A duvet appeared from nowhere, settling over Sherlock. He hadn’t realized he was shivering until warmth enveloped him.
“Better?”
Sherlock managed a sound that might have been agreement. Speech felt impossible. Instead, he let himself sink into John’s careful attention, the methodical way fingers traced patterns across his shoulder blades.
Time became elastic. Minutes stretched into hours, or perhaps hours compressed into heartbeats. Sherlock existed in a suspended state between sleep and waking, tethered only by John.
“Why?” The word escaped before Sherlock could stop it. He couldn’t complete the sentence. Why have you stayed?
“Because you need it”. John’s hand never paused in its gentle circuit across Sherlock’s back. “Because everyone needs someone to catch them when they fall”.
Another piece of chocolate appeared, this one dissolving more slowly on his tongue. The sweetness grounded him, pulled him incrementally back toward himself. His pulse had settled into something approaching normal. The trembling in his hands had subsided.
“I don’t…” Sherlock began.
“I know”. John’s thumb traced the knob of Sherlock’s spine. “That’s what makes this precious”.
Precious. Another word that ricocheted strangely through his consciousness. When had Sherlock last been precious to anyone? When had he allowed himself such softness?
The questions could wait.
For now, he breathed.
Outside, London hummed its eternal song.
Inside, Sherlock learned to fall safely.
Softly.
To let gravity claim him.
Without fear of impact.
To surrender control.
Knowing someone else would guide his descent.
Catch him mid-flight.
With his steady hands.
