Rainbow and Violet the echidnas had finally been reunited. However, their sisterly reunion was not exactly under the best of circumstances. The last thing either of them remembered before blacking out was the frightening visage of Shadow Chaos, the black, yellow eyed version of Chaos that had been periodically emerging to run amok recently. Now, they awoke in what appeared to be a secluded back alley of the Hidden Ruins, the ancient underground city where Rainbow made her home. They hugged in relief when they noticed each other, but their reunion was quickly interrupted.
A puddle of black slithered towards them, and from it, Shadow Chaos rose! "You... The dark version of Chaos! What do you want??" Violet gasped. Shadow Chaos's hands split into long, black tendrils, which he used to swiftly tear the clothes from the echidna sisters' bodies! "Eeek! I-I think it wants US, Viola!" Rainbow yelped. Confirming Rainbow's thought, Shadow Chaos extended his arms into the girls, black fluid surrounding their bodies and lifting them into the air! In moments, each of them struggled out of the blackness and were caught in a tangle of black, watery tentacles! "L-let us go! What are you doing!?" Violet gasped, feeling the tentacles wrap around her arms, legs, and body just tightly enough to stop her from pulling free. The yellow eyes of Shadow Chaos gazed over the nicely curved bodies covered in fine purple and yellow fur, his many tendrils rubbing over every inch of the lovely creatures. Rainbow willingly opened her legs, softly moaning as the tentacles massaged her. "Ah... If you insist, just don't hurt us..." she panted. A new tentacle shot from Shadow Chaos's arm and shoved its way deep into her pussy, accepting her invitation! Rainbow cried out, blushing as Violet watched in horror. "N-no! Don't even..." she gasped, only to feel her legs pulled apart, granting entrance to the incoming tentacle that plowed its way deep into her passage! She let out a shriek as the dark creature probed the sisters' depths, its black tentacles coiling around their breasts and playing with them as the echidnas writhed in the tangled grip! Rainbow went with the flow, cries of ecstasy escaping her as the inserted tentacle invaded her womb! Only the tendrils coiling around her quills seemed to bother her, and she tugged her head to try to escape them. Violet, however, writhed furiously, trying to escape! Every thrust into her depths forced her to moan in defeated pleasure, and she simply could not wrest herself free! Shadow Chaos pulled her closer, removing the tentacle in her pussy and thrusting his crotch at her instead! Violet felt a much more masculine shape than the tentacles penetrate her flower. "AAHH!! NO!! Why me!? STOP!! Rain-bow likes it!!" Violet protested, but Shadow Chaos just kept thrusting into her passage, keeping her tangled in tendrils to prevent her escape!
"Aaaahhh!! S-so... GOOD!!" Rainbow cried as some form of climax erupted from the tentacle inside her! Violet wailed as Shadow Chaos came inside her as well, tears streaming down her face. Then, the sisters were gently placed on the ground. "...Huh? We... get to live?" Violet murmured. Shadow Chaos slithered away silently, but something about his demeanor told them he'd find them again. "You okay, Viola?" Rainbow asked as the sisters laid naked on the dirt floor. Violet rolled over and gently hugged her sister. "I... love you, sis." she sighed, kissing her cheek. Rainbow giggled and nuzzled her cheek as she started drifting to sleep. "Me too... Next time maybe we'll share a less scary friend..." she sighed, thinking about whether Punchy might be up to pleasing both of them. Violet nodded, chuckling softly.

The end.
