Chiasm
Was it time? Oh, oh, was it really time!! Yes.~ Yes it was!
Something, someone, had sat on her... it cribbled, yes, yes! Eating the animals and replicating their nerves had made it possible, all of it! Yes!
Now... what to do, the soft thing was shaped... ah, yes like the one she ate, just a bit bigger and softer. Two lumps and a gap... oh, two gaps, right...
With little consideration to what had happened so far, Chiasm let the trap spring.
Collecting some of her mass right below the spot Sakura was sitting, she shot a single protrusion upwards like a torpedo... sadly without taking into account the fact that there were a skirt and black lace panties in between her soft protrusion and the target...
"Umu....;" the couch whined, unsure what to do, when instead of slipping into the passage properly, she had shoved the gellatinous tentacle into Sakura's puckered asshole only by a quarter of the amount intended... however despite being only a finger length inside, she had instead managed to cram both the girl's panties and even the fabric of her skirt into her rear. Trying to figure out what was going on, Chiasm thus extended more appendages, wrapping them around Sakura's legs to have her remain seated for now... time to figure out how to solve this mess...
