The Predicament

 

Victim is submerged inside a thin cylindrical tank full of an aphrodisiac solution. Hoists are wound around the victim's arms, allowing them to breach the surface of the solution for air.

The victim only needs to empty the Refill Tank to end the torture (i.e. even though they are drinking from the Submersion Tank, they do not need to empty it too).

However, the hoists are attached to valves - whenever tension is applied to the hoists, the valves open, replenishing the solution inside the Refill Tank. The longer the victim stays above the surface, the more progress is undone by their tardiness.

CYOA Parameters (generally Mild first -> Extreme last within each category):

Initial Volume of Refill Tank:

• 1 Liter - A fairly short experience, but still long enough to immerse the victim within the tank and leave them twitchy.
• 3 Liters - This experience ought to last long enough for the victim to get a proper soak.
• 8 Liters - The victim may be in there for the best part of a full 24-hour day. Perfect for ensuring that the aphrodisiac has been fully absorbed inside and out.
• 50-200 Liters - An exhausting marathon experience that may take weeks depending on the volume chosen. The victim will work in shifts of a few hours at a time, being allowed to surface without penalty (and given an inflatable pillow) during breaks, but will not be permitted to leave the tank until the torture is over. Side effects may include muscle deterioration and skin immersion syndromes. Soaking in an aphrodisiac for this length of time will greatly intensify the magnitude and permanence of the effects.
• 50-200 Liters (no breaks) - The victim should be prepared to face sleep deprivation, painful muscle fatigue, near-total loss of sanity, and many more delightful side effects of their seemingly endless and constant torture.

Solution Concentration:

• 10% - Victim experiences slightly heightened arousal and a mild yet sensual tingling feeling in some areas of the skin.
• 25% - Victim experiences moderately heightened arousal, skin becomes noticeably more sensitive, refractive period decreased.
• 50% - Victim becomes agitated and twitchy when not actively being stimulated, large areas of usually insensitive skin become new erogenous zones, almost zero refractive period. Victim begins to drool, lactate and leak precum/pussy juice.
• 75% - Victim compulsively touches themselves and/or finds things to rub themselves against. Victim is seemingly unable to resist panting and moaning in a slutty voice. Entire body becomes an erogenous zone. Areas that were sensitive prior to submersion now become painfully sensitive, yet needy for stimulation. Victim begins to drool and lactate heavily and leak pre/juice almost as if they were pissing it.
• 90% - Purest solution while still giving the victim nutrients and water. Even after being taken out of the tank, the victim will writhe around in a puddle of their own bodily fluids, unable to coordinate their muscles enough to maintain balance or composure, and unwilling to part with the floor unless they find something/someone more suitable for grinding/humping against.

Additives:

• Semen Milkshake - Self-explanatory.
• Chronic Agent - Normally the effects of the aphrodisiac would only last a few hours to a single day, but depending on how much chronic agent is added, the effects can be made to last up to a year.
• Thickener - Corn flour is added, turning the solution into a thick sludge, making it much harder to drink and much more filling, thereby vastly increasing the time that the victim has to spend inside the tank.
• Emetics - A small number of emetics are added to the solution. Even with their best effort, the victim will be forced to vomit and undo a significant amount of progress every so often. Emetics are medicines or other substance which causes vomiting.
• Drug Cocktail (non-addictive) - a cocktail of psychoactives, stimulants, and hallucinogens is added to the solution.
• Drug Cocktail (addictive) - a cocktail of many different drugs, all chosen specifically for being highly addictive, is added to the solution.

Stimulation:

• Default - The victim wears an anal plug, a fleshlight and cock ring (if they have a cock) a dildo and clit stimulator (if they have a pussy) or both (if futa).
• Vibrating - The toys inside the victim constantly vibrate at different settings depending on what seems to cause the victim most agitation.
• Sound - If the victim is male/futa, a sounding rod is inserted into their cock. The rod will also vibrate.
• Stretch - If the victim is male/futa, a ball stretcher is wrapped over their testicles. The victim will also be made to wear a device which will massage their balls and give CBT.
• Nipple Clamps - Self-explanatory. Will also vibrate.
• Brushes - Pads with rotating bristles will be attached around the victim's erogenous zones, further massaging the aphrodisiac into their skin.
• Ticklish - The bristle pads will also be attached to the victim's soles, stomach, armpits, and anywhere else where the victim shows signs of being ticklish.
• Full Body - The victim will be forced to wear a bodysuit lined with bristle pads, artificial tongues, and other devices to massage and stimulate their skin as intensively as possible from the neck down. Only their head may be left exposed.

Breathing Space:

• Smile! - A webcam points towards the tank, streaming high-def clips of the victim's pleasured, gasping face to a public porn site every time they breach for air.
• Claustrophobia - A one-way mirror lid is fitted over the tank, barely an inch or two above the surface of the solution. The victim must crane their neck upwards to gain any air at all.
• Bukkake - A circle of men/futas stand crowded around the rim of the tank, edging themselves so that they're ready to shoot their load any time the victim breaches for air. If they're not careful, the victim may accidentally inhale some thick jizz and have to spend vital time coughing it back up. (Also, this option will obviously mean that the solution turns into a "Semen Milkshake" even if that option wasn't selected earlier.)
• Audio Hyperstimulation - A circle of people stand crowded around the rim of the tank, constantly yelling slurs, discouragement, and generally degrading insults as loud as possible any time the victim breaches. Speakers play Igorrr at full volume with the sound directed and focused towards the tank.
• No Escape from Pleasure - The air in the room above the tank is fogged with an almost chokingly thick aphrodisiac mist.
• Time Pressure - A transparent plastic dome lid is fitted over the tank. The lid is airtight. There are oxygen tanks with enough O2 that the victim should be able to finish the torture in time as long as they are moderately quick, but these tanks are not replenished. Depending on the level of safety (see the relevant sextion), once the O2 tanks are empty, the torture ends with either no consequence, another punishment, or death.

Hoists:

• Automatic - The ropes around the victim's arms automatically retract every 20 seconds, and the victim is not lowered back down until they are clearly comfortable and replenished of air.
• Switch Activated - There is a switch in one of the victim's hands that they can toggle to raise/lower themselves, without requiring muscle strength.
• Aided - Flotation devices are attached to the victim's waist, helping to reduce the strain on their muscles.
• Manual - The victim must overcome their own body weight and pull themselves partially out of the tank each time they need air, no matter how exhausted they become.
• Weighted - Lead bricks are strapped to the victim's calves, and their ankles are anchored to the base of the tank with elastic cord to the point where they will struggle even at the start of the torture.

Safety:

• Full Safety - The victim knows a safe word to end the torture prematurely. Also, if the victim shows any sign of starting to drown, they are hoisted out immediately with no consequence.
• Punishment for Failure - The victim knows a safe word, but knows that using the safe word will sentence them to another type of punishment. If the victim shows signs of drowning, they are hoisted above the surface (and given CPR if necessary) but they receive intermittent shocks through their dildo/anal plug/cockring for the next 5 minutes.
• Extreme Torture - There is no safe word. If the victim shows signs of drowning, they are only hoisted out at the last minute, and given minimal CPR before the torture hastily resumes. They are then artificially stung with an extremely itchy venom around their erogenous zones, and shocked continuously at full power for 5 minutes.
• No Safety - There is no safe word. (SUPER not recommended unless your name happens to rhyme with Funko Fenosh-femur)

Aftercare:

• Redemption - The victim is given soothing aftercare, professional therapy if needed and luxury accommodation while they recover. They are also given a decent compensation.
• Heaven - The victim is given free BDSM session in order to explore and enjoy the effect of the aphrodisiac in a safe and consensual way.
• Acquittal - The victim is given back most of their clothes and given just enough money to get back home using public transport (but no provisions for if the aftereffects get them into trouble on the way back or at home itself...).
• Purgatory - The victim is cuffed and detained in a very basic room until the effects wear off, with absolutely no way to satisfy their constant sexual urges.
• Condemnation - The victim is detained in a BDSM dungeon full of toys designed to overstimulate them and break their mind. After their mind has been sufficiently broken, they are coerced into signing up for another round inside the tank.
• Hell - The victim is sold into sexual slavery and will serve a particularly cruel and brutal clientele for the rest of their life. Also, the victim is brought back to the tank at regular intervals fully irrespective of their own desires or boundaries.
