Ah, one of my favourite dungeon creatures~ The pits are tubular tentacle monsters from a swamp in a hellish dimension. They produce a slimy substance that just happens to be a strong aphrodisiac. As soon as prey falls into the large opening at the top of the pits, the tentacles inside start searching for orifices to enter and drain their victims through. Luckily for us, the tentacles aren’t strong enough to harm anyone in our realm, though they certainly try by writhing and slithering against any soft tissues they find – causing intense pleasure and a feeling of being “filled to the brim” with a moving mass of slimy flesh. The trainees in this exercise have only one goal: Escape from the pit. Due to the slippery nature of the pits as well as being placed inside ass-first, that’s quite the difficult task while also slowly being driven crazy from the ruthless tentacles. To add insult to injury we also placed some grips above each pit, sadly they happen to be slightly out of reach~
