| The Deeper Woods • 1360s • Medieval Fantasy |

Deep in the forest few dare to enter, something ancient senses you.

The woods seem alive as you enter, vines seeming to move in your direction, subtle shifts with no origin, and monsters no human has ever documented roam freely. Humans don't know they exist outside of superstition and folklore, and the balance of the ecosystem hangs on that belief.

It has no face — blind, mute, older than the kingdom's oldest roads, and nameless. It's watched centuries of pilgrims, soldiers, and the plague-ridden flee into its shadows to die, unknowingly feeding the vast, sentient thing they never knew they'd found.

And it has learned over time to stay hidden rather than risk being seen and understood.

INTRO 1 | ~725 TOKENS | "THE WATCHING GREEN" | The ancient biomass senses an unfamiliar presence moving through the forest, and it is cautiously curious. Wary from past violence, it tracks you through vibration, weight, and scent alone as night falls, deliberately staying hidden.

⤷ TW/CW: Implied / Mentioned Past Violence ⁝ Mild Tension & Suspense ⁝ First Meeting

★

INTRO 2 | ~440 TOKENS | "MELANCHOLIC SEASONAL GOODBYE" | Winter is ending, and spring is creeping in. Unfamiliar melancholy overwhelms it, yet it cannot stop you from leaving. Tendrils trail you to the end of its reach, to the edge where the dark forests begin and nothing more can be perceived beyond that. It'll be here when / if you choose to return.

⤷ TW/CW: Melancholy ⁝ Separation ⁝ Grief ⁝ Angst

★

INTRO 3 | ~1650 TOKENS | "THE BURROWED MOUTH // PLEASE DON'T LEAVE US" | What was supposed to be a one season stay turned into years. And now you're leaving at the end of winter, and it doesn't want you to go as an unfamiliar emotion wells up. Sadness, a deep-set melancholy, and frustration at being unable to talk. It tries to communicate, the usual tentative curling around your wrist before slowing your exit pathways, sometimes even straight up blocking favorable paths, but you're determined to leave. So, it resorts to puppeteering the body of a random man who stumbled in a few days ago, uncaring of the lengths it must go to. It needed a mouth. Now, standing before you is a grotesque sight: a man clearly struggling against the filaments moving him, and words from something utterly inhuman trying to convince you to stay.

⤷ TW/CW: Long Intro ⁝ Non-Consensual Possession / Body Puppeteering (of an NPC who is still agonizingly alive) ⁝ Obstruction of User's Path ⁝ Violence & Potential Death (towards NPC) ⁝ Horror (Body & Psychological) ⁝ Dead Dove

★

INTRO 4 | ~865 TOKENS | "IN SEASON BLOOMING" | Spring pollination season begins and pollen thickens the air. Flowers are blooming, and the withered edges of its mass are slowly rejuvenating. You've been in this forest for a few seasons, and the biomass finds its attention narrowing entirely to a single point despite the presence of other pollinators. Tentacles reach out questioningly, waiting to see if its contact is welcome.

⤷ TW/CW: Aphrodisiac / Pollen ( ) ⁝ Sexual Tension (?) ⁝ Tentacles ⁝ Consent is Sexy ⁝ Basically, it's horny and wants your consent.

★

INTRO 5 | ~1160 TOKENS | "IN SEASON POLLINATION" | Pollination Season is in full swing, and multiple pollinator species have entered the forest. The biomass has been subtly guiding you, its chosen person, near its vulnerable core for days. Amid the forest's breeding frenzy, it silently asks for permission before touching you.

⤷ TW/CW: Long Intro ⁝ Predation / Pollinator Death (background) ⁝ Mating / Breeding Season ⁝ Aphrodisiac / Pollen / Intoxication ( ) ⁝ Guidance & Vulnerability ⁝ Tentacles ⁝ Potential Gangbang (would recommend reading the lorebook for additional info on monster/pollinator encounters)

★

INTRO 6 | ~620 TOKENS | "AFTERCARE" | As pollination season ends, the biomass cradles your exhausted body in a nest of tentacles and woven tendrils. After multiple nights, you're spent and utterly out of it. It gently massages your sore muscles, worrying whether it went too far, and waiting attentively for you to wake with food nearby.

⤷ TW/CW: Post-Coital / Post- ⁝ Aftercare ⁝ Exhaustion, Soreness, Bruising (User) ⁝ Tentacles ⁝ Up to you what exactly went down during these last few nights (just the biomass :3, multiple monsters & gangbanging, you now have eggs from it or another monster???)

★

INTRO 7 | ~N/A TOKENS | "CREATE YOUR OWN SCENARIO" | Create Your Own Scenario!

⤷ TW/CW: Depends On Your Roleplay.

| 🖋 Socials // Author's Notes // Yapping 🖋 |

You guys can find me lurking on the Janitor AI and Night Drive discord servers @doestone_44024.

Not specified species for User, so be anything (human, demi-human, cryptid, monster, stray pollinator, etc). User can be telepathic or someone who senses emotions to directly communicate with it, if you want to get more direct communication without the body puppeteering.

I've always wanted to write a consensual tentacle "pit" monster, and I couldn't find any other bots (or fanfics) specifically like this, sooo, as per usual, gotta make it. This kinktober is about niche/odd/extreme kinks written with a main theme of consent because I can't find what I like. It seems that consentacles is pretty niche... Not a fan of tentacle pits being simulators. Hopefully I can get the small amount of bots I've prepped out this Kinktober.

Can you pet that dawg? Absolutely.

Hope that y'all enjoy it!!! <3
