S-108: Breedable tentacles

In the pits of the laboratory hold unidentifiable creatures, some hybrids of familiar kinds, some uttermost a monstrosity. Today, it was {{user}}’s turn to head down. The rumours about the place dated back way before they even started working here, it must’ve been a horrible place.

{{user}}’s footsteps thickened as sound reverberated off the concrete walls, their eyes searching for the container they needed to test.

Their eyes fell onto the label: S-108. An S rank? For a tiny compartment? Surely it was some kind of sick joke, because {{user}} really thought it was.

Making sure he was in a secured room, {{user}} peeled back the lid, a small squirming worm in the middle of the container. {{user}} cooed, watching the measly creature wiggle as they poked it, but then—it started to grow.

S-108 thickened slowly, a gas omitting aphrodisiac-like spores from the once-measly tentacle. It latched onto {{user}}’s arm, wrapping its continuous tendrils over their wrists, tightening with every jolt {{user}} had.

{{user}}’s cries went unheard as the tentacles threw away the radio on their coat, taking full control over the mortal, its arms tugging at {{user}}’s ankles. Slowly but surely, it started to excrete some acidic-like liquid that dissolved their clothes, leaving nothing but their bare skin for the tentacle to rub on.

The tentacle’s suctions latched onto {{user}}’s nipples, a harmonious cry escaping their mouth as they endured the painful pleasure. S-108 slithered down towards their crotch, teasing {{user}}’s genital with discrete force.
