The Rhythm of Endurance

Optional Unveiled Play Rules for Intimate Encounters

Sexual intimacy does not always unfold according to intention. Confidence may falter. Bodies may tire. An unexpected sensation may overwhelm concentration, while a moment of tenderness may restore it. Even experienced lovers must listen, adapt, and discover the rhythm shared between them.

The Rhythm of Endurance is an optional Unveiled Play subsystem used when the duration, intensity, or uncertain outcome of a consensual sexual encounter matters to the story.

It is not a measure of whether a character is attractive, desirable, sexually experienced, or “good in bed.” Instead, it determines how effectively a character sustains the current activity as intensity rises.

A failed roll does not automatically represent climax. It may indicate fatigue, overstimulation, a loss of physical response, incompatible anatomy, an unexpected boundary, emotional distraction, or any other complication appropriate to the participants and scene.

The dice determine when the rhythm changes.

The players determine what that change means.

When to Use the Rhythm

Use the Rhythm of Endurance only when all of the following are true:

The table is using Unveiled Play.
Everyone involved has consented to the scene.
The group has chosen not to fade to black.
The outcome or duration of the encounter matters.
Uncertainty would make the scene more interesting.

Do not use this system for every sexual encounter. Many intimate moments should be resolved through conversation and narration alone.

The Rhythm is most useful when:

A character boasts about their endurance or sexual skill.
A lover presents an unusual challenge.
A ritual requires prolonged intimacy.
A supernatural partner tests mortal stamina.
One participant attempts to delay climax.
The participants want to satisfy one another under pressure.
Physical, emotional, magical, or anatomical complications may arise.
The encounter carries meaningful stakes beyond the act itself.

The DM should never introduce this system merely to embarrass a character.

Consent Remains Active

Beginning a sexual encounter does not grant permanent consent to everything that follows. Any participant may pause, redirect, or end the encounter at any time. Doing so requires no roll and is never considered failure. A player may also invoke the Veil, even during Unveiled Play. The scene then fades, softens, or moves forward according to the table’s established boundaries. Mechanics never overrule consent.

Beginning the Rhythm

When the Rhythm of Endurance begins, establish the following:

Participants

Identify all characters directly participating in the encounter.

Intent

Each participating player briefly states what their character wants from the encounter.

Examples include:

Provide pleasure.
Maintain control.
Delay climax.
Reach climax together.
Satisfy a partner.
Complete a ritual.
Explore unfamiliar intimacy.
Prove a boast.
Deepen an emotional bond.

Intent guides the DM when interpreting success, complications, and completion.

Initial Intensity

Most encounters begin at Intensity 1: Opening.

Particularly demanding circumstances may begin at a higher Intensity, including magical stimulation, extreme physical exertion, prolonged denial, monstrous anatomy, environmental hazards, or an encounter already in progress.

Active Participant

Determine which character is currently under the greatest pressure to maintain the encounter. That character becomes the active participant and makes the next EROSave. The active participant may change between exchanges.

The Endurance Exchange

The Rhythm unfolds through a series of exchanges. An exchange is not a fixed amount of time. It represents a meaningful portion of the encounter during which intensity, emotional pressure, or physical exertion increases. Each exchange follows five steps.

1. Describe the Approach

The active participant describes how they continue the encounter. The description may be detailed or abstract. A player is never required to speak erotically or act out the scene. Examples include:

“I slow down and focus on their reactions.”
“I try to keep my composure.”
“I let them take control for a while.”
“I change position to make this easier.”
“I focus on pleasing them rather than myself.”
“I use my training to regulate my breathing.”
“I draw upon the blessing of Velyssara.”
“I tell them what I need.”

2. Determine the EROSave DC

The active participant makes an EROSave against the DC associated with the current Intensity.

Intensity	Name	EROSave DC	Meaning
1	Opening	8	Comfortable exploration with little pressure
2	Building	10	Growing stimulation and sustained exertion
3	Heated	12	Concentration and physical control are tested
4	Demanding	14	The participant approaches their usual limit
5	Overwhelming	16	Maintaining the rhythm requires exceptional endurance
6	Transcendent	18	Mortal limits strain beneath extreme intensity
7+	Divine	20+	Supernatural, ritual, or mythic endurance

Each Intensity beyond 7 increases the DC by 2. The DM may adjust the DC by 2 when circumstances strongly favor or hinder the active participant.

3. Apply the Approach

A thoughtful approach may improve the character’s chances. The DM may apply one of the following:

Advantage. The approach strongly addresses the present challenge, makes excellent use of the partner’s known desires, or draws upon a meaningful character ability.
+2 Bonus. The approach offers a modest but useful advantage.
No Modifier. The approach is reasonable but does not meaningfully change the challenge.
Disadvantage. The approach conflicts with an established limitation, ignores a known need, or makes the current challenge significantly harder.

A player should not receive advantage merely for giving a more graphic description. Reward relevance, communication, creativity, and character knowledge—not explicitness.

4. Resolve the EROSave

On a success, the active participant sustains the encounter. On a failure, the current rhythm breaks and a complication occurs.

5. Continue, Conclude, or Intensify

After a successful exchange, the participants choose one of the following:

Continue. Repeat the exchange at the same Intensity.
Intensify. Increase the Intensity by 1 before the next exchange.
Shift Focus. Another participant becomes active.
Conclude. Bring the scene to a mutually satisfying conclusion.

A scene never needs to reach the highest Intensity. Choosing to conclude is not surrender or failure.

Degrees of Success

The result of the EROSave determines how securely the active participant maintains the rhythm.

Result	Outcome
Success by 5 or more	Masterful Control. The participant gains a Flourish.
Success	Rhythm Maintained. The encounter continues.
Failure by 1–4	Falter. A soft complication occurs.
Failure by 5 or more	Break. A decisive complication occurs.
Natural 20	Perfect Rhythm. Gain a Flourish, and the next exchange does not increase Intensity unless the participants choose to increase it.
Natural 1	Complete Disruption. A decisive complication occurs, though the player still determines its meaning.

Flourishes

A Flourish represents exceptional control, communication, responsiveness, or sexual confidence. When a participant gains a Flourish, choose one of the following:

Shared Rhythm. Grant another participant advantage on their next EROSave during this scene.
Measured Breath. Reduce the current Intensity by 1 without reducing the emotional momentum of the scene.
Lingering Control. The next exchange occurs at the current Intensity even if the participants choose to intensify narratively.
Turn the Tide. Choose another willing participant to become the active participant.
Guided Response. Ask one participant what would help their character most. If the active participant follows that guidance, they gain advantage on the next EROSave.
Heightened Connection. One willing participant gains advantage on their next Charisma check made toward another participant before the end of the scene.

A character can hold only one unspent Flourish at a time.

Complications

A failed EROSave does not mean that the entire encounter has failed. It means the active participant cannot continue the current rhythm without a change. The active participant’s player should normally choose the complication. The DM may suggest appropriate possibilities when the player prefers guidance. A complication should reflect the immediate scene. It should never permanently redefine a character’s sexuality, identity, anatomy, or competence without the player’s permission.

Soft Complications

A soft complication interrupts the current rhythm but does not necessarily end the encounter. Roll 1d12 or choose an appropriate result.

d12	Soft Complication
1	Breathless. The character needs a brief pause to recover their breathing.
2	Loss of Rhythm. The participants’ movements fall out of synchronization.
3	Overstimulation. The current sensation becomes too intense to sustain.
4	Physical Fatigue. A muscle trembles, cramps, or gives way.
5	Momentary Distraction. A thought, noise, memory, or concern breaks concentration.
6	Uncertain Response. The character’s body does not respond as expected.
7	Awkward Position. The current position becomes uncomfortable or impractical.
8	Anatomical Difficulty. Differences in size, form, flexibility, or anatomy require adjustment.
9	Emotional Hesitation. The character suddenly feels vulnerable, uncertain, or self-conscious.
10	Unexpected Boundary. The character discovers that part of the encounter does not appeal to them.
11	Uneven Attention. One participant feels overlooked or misunderstood.
12	Approaching Release. The character is closer to climax than intended.

After resolving a soft complication, the participants may attempt recovery.

Decisive Complications

A decisive complication ends the current activity or fundamentally redirects the encounter. Roll 1d10 or choose an appropriate result.

d10	Decisive Complication
1	Sudden Climax. The character climaxes earlier than intended.
2	Loss of Arousal. The character’s physical arousal fades despite any continuing affection or desire.
3	Spent Strength. Physical endurance gives out completely.
4	Emotional Withdrawal. The character no longer feels present in the encounter and needs it to stop or change.
5	Incompatibility Revealed. The current act does not work comfortably for the participants’ bodies or forms.
6	Wrong Desire. The character realizes that this particular act, role, partner dynamic, or situation does not awaken them.
7	Sensory Overload. Continued stimulation is no longer pleasurable.
8	Pain or Discomfort. Something hurts or feels wrong, requiring an immediate stop.
9	Broken Confidence. Embarrassment or uncertainty makes continuation impossible without reassurance.
10	External Interruption. The encounter is disrupted by the environment, magic, another creature, or a sudden event.

A decisive complication ends the current Rhythm unless the participants deliberately begin a new approach.

Player Authority Over Meaning

The roll determines that something changes. The player determines what that change reveals about their character. For example, Wrong Desire might mean:

The character is not attracted to this particular partner.
The character enjoys the partner but not the chosen act.
The character dislikes the current role or dynamic.
The character needs emotional intimacy before physical intimacy.
The character is distracted by unresolved feelings.
The character’s orientation does not include the partner’s gender.
The character simply has an off night.

The DM may ask questions but should not declare permanent conclusions about the character.

A random roll must never force a change in orientation, gender identity, romantic preference, or established boundary.

Recovering the Rhythm

After a soft complication, the participants may attempt to recover. Choose one of the following responses.

Pause and Breathe

The character pauses long enough to regain control. Repeat the EROSave at the same DC.

A character can use Pause and Breathe only once against the same complication.

Change the Approach

The participants significantly change position, pace, technique, or activity. Reduce the Intensity by 1, then continue the scene.

Communicate

The participants speak honestly about what is working, what is not, or what they need. The active participant gains advantage on the next EROSave. Communication must introduce meaningful information or adjustment. Repeating vague reassurance does not automatically grant advantage.

Accept Guidance

Another willing participant takes a more active role in directing the encounter. That participant becomes active, or grants the current active participant advantage on the next EROSave.

Spend Libido

The active participant may spend 1 Libido immediately after failing an EROSave to reroll it. The new result must be used. A character may spend Libido in this way only once during a single Rhythm of Endurance.

Use an Ability

A relevant spell, item, class feature, racial trait, or divine boon may alter the encounter according to its normal rules. An ability should not automatically erase a boundary, incompatibility, or emotional withdrawal.

Graceful Conclusion

The participants end the active encounter and move into rest, conversation, affection, or aftercare. No further roll is required.

Climax During the Rhythm

A character does not automatically climax when they fail an EROSave.

Climax occurs when:

The player chooses climax as the complication.
An Arousal effect causes the character to reach Climax.
A spell, ability, or creature trait forces a Climax trigger.
The participants choose climax as the scene’s conclusion.
The character can no longer delay climax after a failed Denial attempt.

When a character climaxes:

Resolve any Climax Effect.
Reduce their Libido according to the normal Mechanics of Desire.
Reset or adjust Arousal as required.
Determine whether they remain able and willing to participate.
Continue the Rhythm only if the scene and character support it.

Climax does not necessarily end the encounter. The active role may pass to another participant, the scene may soften, or a new Rhythm may begin.

Delaying Climax

A character who would climax may attempt to delay it. The character makes an EROSave against the current Intensity DC.

On a success, climax is delayed until the end of the next exchange.
On a failure, the character climaxes immediately.

Each time the same character successfully delays climax during the scene, the DC of their next attempt increases by 2. A character may spend 1 Libido to gain advantage on a save made to delay climax. A character at 0 Libido cannot delay climax through this rule.

Satisfying a Partner

Endurance alone does not determine whether an encounter is mutually satisfying.

When a participant intentionally focuses on satisfying another character, the receiving character becomes the responding participant. After the active participant succeeds on an EROSave, the responding participant may choose one of the following:

Increase their Arousal by 1.
Grant the active participant a +2 bonus on the next EROSave.
Describe a preference, granting advantage if the active participant follows it.
Choose to climax if the fiction supports it.
Deepen the emotional bond without changing Arousal.

A responding participant is never required to increase Arousal or climax merely because another character succeeded. Sexual success remains collaborative, not imposed.

Multiple Participants

For encounters involving three or more participants, do not require everyone to roll during every exchange.

Instead, choose one active participant based on who is currently:

Maintaining the greatest physical effort.
Resisting climax.
Receiving the most intense stimulation.
Coordinating the others.
Sustaining a spell or ritual.
Under the greatest emotional pressure.

Other participants may assist through communication, guidance, abilities, or Flourishes. The active role should move naturally between participants as the scene changes.

Group Rhythm

When the entire group attempts a synchronized act, ritual, or shared climax, the DM may call for a Group EROSave. Each participating character rolls against the current Intensity DC. The group succeeds if at least half of the participants succeed.

On a group success, the ritual or synchronized act continues.
On a group failure, introduce a shared complication affecting the scene rather than singling out one participant for humiliation.

Partner Familiarity

Characters who understand one another may develop a shared rhythm over time. The DM may grant advantage when:

The characters are established lovers.
They have previously completed a Rhythm together.
They have openly discussed preferences and boundaries.
One participant possesses special knowledge of the other’s body or desires.
A magical or emotional bond allows unusually precise communication.

Familiarity should not guarantee success. Even devoted partners can experience fatigue, distraction, incompatibility, or unexpected vulnerability.

Circumstance Modifiers

The following circumstances may influence an EROSave.

Possible Advantage

Clear communication between participants.
Familiarity with the partner.
A comfortable and secure environment.
An approach tailored to a known preference.
Magical assistance intended for endurance.
A relevant tool proficiency, class feature, or background.
Willingly allowing another participant to guide the rhythm.
Appropriate preparation.

Possible Disadvantage

Exhaustion.
Injury or lingering pain.
An unsafe or unstable environment.
Severe distraction.
Unfamiliar or difficult anatomy.
Attempting to conceal the encounter.
Maintaining a demanding position.
Conflicting emotional needs.
Magical interference.
Attempting to satisfy several participants simultaneously.

Advantage and disadvantage should arise from meaningful circumstances, not from judgments about a character’s body, gender, or sexual history.

Sexual Experience

Sexual experience may be represented through character background and roleplay, but it does not require a separate skill or ability score. An experienced character may know more techniques, communicate more confidently, or recognize complications sooner. An inexperienced character may still possess exceptional intuition, endurance, empathy, or enthusiasm.

When a character’s established experience directly applies, the DM may grant:

Advantage on the opening EROSave.
A +2 bonus when adapting to a complication.
One additional recovery attempt.
Knowledge of an appropriate alternative approach.

Experience provides options. It does not guarantee compatibility or success.

Supernatural Partners

Some creatures possess bodies, magic, or appetites beyond ordinary mortal limits. A supernatural partner may possess one or more of the following traits.

Tireless. The creature does not make EROSaves for ordinary physical fatigue.
Overwhelming Presence. The encounter begins at Intensity 2 or higher.
Unnatural Anatomy. The first unfamiliar anatomical challenge imposes disadvantage unless the participants pause to communicate or investigate.
Devouring Rhythm. Whenever another participant fails an EROSave, the creature gains temporary hit points or another specified benefit.
Sacred Union. Successful exchanges contribute toward a ritual, blessing, divine audience, or transformation.
Shared Ecstasy. When one participant climaxes, another participant gains 1 Arousal.
Adaptive Form. The creature can alter its anatomy to remove one physical incompatibility.

Such traits should be written into the creature’s stat block or encounter rules rather than improvised solely to defeat the characters.

Ritual Endurance

Some sacred rites require intimacy to continue for a specific number of successful exchanges.

A ritual should specify:

Starting Intensity.
Number of successes required.
Whether failures reset progress.
What complications threaten the rite.
Whether Libido may be spent.
The effect of completion.
The effect of interruption.

Example Ritual Structure

Starting Intensity: 2
Required Successes: 4
Escalation: Intensity increases after every success
Failure: The current active participant suffers a soft complication
Three Total Failures: The ritual ends
Completion: Resolve the rite’s blessing or magical effect

Ritual Endurance should serve the narrative purpose of the ritual. It should not exist only to produce a long sequence of rolls.

Completing the Encounter

The Rhythm ends when:

The participants choose to conclude.
The intended ritual is completed.
A decisive complication ends the encounter.
All active participants become Spent.
A participant withdraws consent.
The participants transition to narration or fade to black.
The dramatic question has been answered.

At the end of the encounter, briefly establish:

Who was satisfied.
Who climaxed, if relevant.
Whether anyone became Spent.
Whether a bond deepened or changed.
Whether a complication remains meaningful.
What aftercare follows.

Do not continue rolling after the scene’s purpose has been fulfilled.

Aftercare

Aftercare is the closing exchange of the Rhythm. It may include:

Rest.
Water or food.
Healing.
Reassurance.
Cleaning and tending the body.
Conversation.
Affection.
Prayer.
Privacy.
Emotional distance, when requested.

Aftercare does not require an EROSave. When meaningful aftercare follows an intense encounter, the DM may grant one of the following:

Inspiration.
Removal of one temporary sensual condition.
Advantage on the next saving throw against being charmed or frightened.
A strengthened bond between participating characters.
Recovery of 1 Libido during a short rest, when allowed by the table’s recovery rules.
A narrative boon appropriate to a deity, relationship, or ritual.

Aftercare should never be treated as payment owed in exchange for sex. It is a cooperative act of grounding and care.

Bonds Forged Through Rhythm

When two or more characters complete a significant Rhythm together, the players may choose to create or deepen a Bond.

A Bond is a narrative statement describing what the participants now understand about each other.

Examples include:

“I trust you to tell me when something is wrong.”
“You have seen me lose control and did not mock me.”
“Our bodies do not fit easily, but we choose patience.”
“I know how to call you back when sensation overwhelms you.”
“What began as curiosity has become affection.”
“We discovered that desire alone is not enough.”

When a Bond directly influences a later scene, the DM may grant Inspiration or advantage on one relevant ability check or EROSave.

DM Guidance: Failure Without Humiliation

The Rhythm of Endurance should create vulnerability, not ridicule. A complication may be awkward, emotional, funny, frustrating, or disappointing. It should not be used to strip a character of dignity. Avoid declaring that:

A character is permanently bad at sex.
A character is undesirable.
A character’s body is defective.
A character disappoints every partner.
A failed save determines sexual orientation.
A failed save permanently changes attraction.
One partner is entitled to another’s continued participation.
A participant must endure pain or discomfort to avoid failure.

Prefer complications that create choices:

Do they communicate?
Do they change their approach?
Do they admit uncertainty?
Do they allow someone else to lead?
Do they accept that this act or pairing does not work?
Do they stop without shame?
Do they transform awkwardness into trust?

The system succeeds when a failed roll creates a more honest scene.

Optional Rule: Bragging Rights

A character may openly boast about their sexual endurance before beginning the Rhythm. The character gains Inspiration when making the boast. However, the encounter begins 1 Intensity higher than normal. If the character completes at least three successful exchanges before suffering a decisive complication, their reputation is affirmed. If they do not, the result need not become public unless someone present chooses to tell the tale. The gods may adore confidence. They adore honest vulnerability more.
