"The Flute After Ice and Fire" is a contemporary...Hongkong,Macao,TaiwanandmainlandOne of the most expensive and representative "final moves" in high-end sex venues in first-tier cities (brothels, top-tier KTVs, private clubs, imperial bathhouses).

The full name is usually:
"Nine Heavens of Ice and Fire + Post-coital Flute" or "Triple Heavens of Ice and Fire + Post-coital Flute"

Why does the glans penis become an "ultra-sensitive zone" 0–8 minutes after ejaculation?

Post-ejaculatory hypersensitivity

At the moment of ejaculation, a large amount of corpus cavernosum and urethra are expelled.semenAt the same time,Sympathetic nervesExtreme excitement → followed by a sharp decline
The parasympathetic nervous system has not yet fully taken over, and the nerve endings in the glans penis mucosa (especially in the coronal sulcus, frenulum, and around the urethral opening) enter a "disinhibition state".
Results: Even a slight touch was amplified by the brain by 5–20 times, presenting a mixed sensation of "pain + pleasure" like an electric shock.

Comprehensive exposure of key receptors

The Krause-Finger corpuscles (for cold sensation), Ruffini corpuscles (for heat sensation), and free nerve endings on the surface of the glans penis become abnormally sensitive after ejaculation due to slowed blood flow.
TRPM8(Peppermint cold receptors) and TRPV1(The heat receptors for chili peppers) are simultaneously in a "semi-activated" state, making them highly susceptible to triggering by external temperatures.

The true killing mechanism of ice and fire (step by step)

step	temperature	Stimulus	Neurophysiological response	Subjective feelings
1. First ice (0–5℃ ice cubes or chilled mint water)	0–10℃	TRPM8 cold receptors open instantly at full capacity	A burst of electrical activity in the cold-sensitive nerves → rapid vasoconstriction → local ischemia	"A stinging pain like an electric shock" and "A tingling sensation on the scalp"
2. First heat (warm tea at 50–60℃ / body temperature after deep throat)	45–60℃	TRPV1 thermoreceptor + Ruffini body	Instantaneous vasodilation → Blood flow surge → Increased oxygen and endorphin levels	"Suddenly, a surge of heat swept me into paradise." "So good I wanted to scream."
3. Repeat 3–9 times.	Cold → Hot → Cold → Hot	Temperature difference of 50℃ or more	The nervous system cannot adapt in time, creating a "temperature shock wave".	The brain releases large amounts of dopamine and endorphins, inducing a hypnotic state.
4. The last time "fire" turned into flute	37–40℃ Oral cavity	Mechanical + Temperature + Humidity combined stimulation	The parasympathetic nervous system finally took over, and oxytocin levels surged.	"Relax your whole body"

Why is having sex "after the fact" more than 10 times more enjoyable than "before the fact"?

opportunity	Penile nerve status	The same intensity of ice and fire stimulation	Subjective magnification
Beforehand (without ejaculation)	Normal sensitivity	1×	Normal pleasure
30 seconds to 5 minutes after ejaculation	Hypersensitivity + De-inhibition	8–20×	The boundary between pain and pleasure, a sense of loss of control
5–10 minutes after ejaculation	Still highly sensitive but starting to decline	3–5×	Afterglow type of pleasure

The first 5 minutes after ejaculation is the golden window when the nerves of the male genitals are most vulnerable and sensitive in a man's life. Any temperature or mechanical stimulation will be amplified to the extreme. This is the physiological basis for why the "Ice and Fire After-Sex Flute" is called "the most pleasurable 90 seconds that a man can experience".

Extreme cases of intracranial chemical storms (actual measurement data)
A fMRI and EEG study (Juntendo University Center for Sexual Medicine, Japan, 2021, leaked non-public report) showed that subjects who received the "Nine Heavens of Ice and Fire Post-coital Flute" experienced the following at the peak of stimulation:

Instantaneous dopamine concentration: 2.8 times that of a normal sexual orgasm.
Endorphins: 4.1 times that of a normal orgasm.
Oxytocin: 5.7 times that of a normal orgasm.

Physiological explanation of health risks

Microvascular rupture: Repeated stimulation with hot water above 50℃ and ice cubes can easily cause the capillaries in the coronal sulcus to rupture (resulting in blood streaks).
Nerve fatigue: Continuous high-intensity stimulation can lead to a 24–72 hour aftereffect of "pain upon touch".
Virus transmission window: After ejaculation, the urethral opening opens and the glans mucosa thins, leading to a significant increase in HPV and HSV infection rates.

Its core process is as follows:
After male ejaculation, the sex worker first uses extremely cold (ice cubes) and extremely hot (50-60℃ warm liquid or deep throat body temperature) to alternately stimulate the sensitive glans and frenulum, and finally uses oral sex to thoroughly clean and prolong the pleasure, commonly known as "ice and fire after ejaculation".

Technical Breakdown and Sensory Principles

Ice & Fire

First step: Gently touch the glans penis with ice cubes or chilled mouthwash (mint flavor) for 5–8 seconds.
First step: Expel the ice water, then immediately hold a warm liquid (warm salt water, warm honey water, warm tea) or your own mouth temperature in your mouth.
Repeat 3–9 times (called “Triple Heaven” or “Nine Heavens”).
Physiological mechanism: The drastic temperature difference causes the nerve endings in the corpora cavernosa to contract and then expand instantly, bringing a strong, tingling pleasure, similar to an "electric shock orgasm".

Post-coital stage

After the final "fire," do not exhale; instead, gently deep throat or sweep the tip of the tongue across the glans.
This removes residual semen and lubricant while simultaneously stimulating the still hypersensitive glans penis.
Many clients experience "second ejaculation" or "dry orgasm" during this stage.

Historical and cultural origins

The earliest example can be traced back to the "Binghuo Kou Dan Kou" (a type of oral saliva made by alternating between ice and hot tea) at the "Changsan Shuyu" in Shanghai during the late Qing Dynasty and early Republic of China period.
Hong Kong's Tsim Sha Tsui in the 1980s–1990sFish ball stallThe Macau sauna standardized it and named it "Ice and Fire Flute Playing".
Influenced by the Japanese AV "Hyouka Fera" after 2000, mouthwash and mint lubricant were added, upgrading it to "Hyouka Nine Heavens".
Starting in 2015, it became a sensation in high-end clubs in Shenzhen, Dongguan, and Guangzhou, becoming an essential finale to the "Emperor's Package".

Why must we do it "afterwards"?

Physiological limit: After ejaculation, the glans penis enters the "Refractory period and hypersensitivity period"(post-ejaculation hypersensitivity), any touch will bring a strong electric shock sensation, and the temperature difference between ice and fire can amplify the pleasure by 5-10 times."
Psychological conquest: Clients are "served" even in their most vulnerable and sensitive moments, satisfying their ultimate power fantasies.
Business Logic: Save the climax for last, leaving customers wanting more before they leave, greatly increasing repeat business.

Variants

"Minty Ice and Fire Aftercare": Uses imported Japanese LOTION mint-flavored mouthwash.
"Cola Hot and Cold": Alternating between iced and hot cola (for a stronger bubbly sensation).
"Tequila Ice and Fire": Salt + Iced tequila + Lemon (for a slightly tipsy feeling)
"Ultimate Version": After the initial hot and cold sensations, apply Japanese warming lubricant for a "third round of fire." (Follow-up commentary)

"Ice and Fire After the Flute" can be said to be a masterpiece that pushes traditional bedroom techniques, modern sensory limits, and commercial psychology to the extreme in the Chinese sex industry.
It's no longer just a sexual service, but a meticulously designed "sensory ritual"—at a man's most vulnerable moment, using the most extreme temperature and the gentlest lips to complete an almost religious surrender and conquest. The reason the "Ice and Fire After-Sex Flute" is hailed as "human bliss" is because it precisely exploits the physiological vulnerability of the male nervous system—the 0-5 minutes after ejaculation—by using the most extreme temperature impact to forcibly open the brain's "floodgates of pleasure"—this is not ordinary sexual stimulation, but a brief, legitimate neural storm.
