Sexperiment 2: Electric Boogaloo

Everything was a blur, every sensation more than her body could stand, but Katarina had managed to make it back to her home with less grace than usual. Tripping through the front door like a drunkard, she found herself in front of her sister, Cassiopeia. Before any questions could come out, Cass realized her sister was fondling herself, a hand trapped between her legs, the other one planted firmly onto her breast, teasing and tweaking the nipple. "CASS HELP ME" she cried out, in a voice not quite her own. Her body was on fire, whatever drug Mundo had put into her system had a hell of a life span. "What is the matter with you?" Cass spat at her, watching her sister struggle to pleasure herself "MUNDO USED SOMETHING ON ME, SOMETHING STRONG, MY BODY IS ON FIRE."
Relenting, because of the pitiful state Katarina was in, Cass closed the door behind her sister, immediately stripping her down to nothing, seizing the opportunity Kat grabbed her sisters hand and greedily shoved it at her soaked cunt, trying desperately to fit the whole thing in. "Relax." Cass commanded, as she pushed the woman back down and went to work. Shoving three fingers in at once, Cass kept her pinned with her free arm, ensuring that the woman would be unable to do anything for the moment at least. Submitting, Katarina allowed Cass to have her way, the lamia eagerly taking dominance. Moving her hand Cass opted to make use of her body, and shoved the end of her tail into her sister, amazed at how deeply the woman was managing to take it. "Gee Kat, you sure have been slutting it up to be THIS loose." she mock-complained, working the tail in and out of her sister relentlessly. Unable to speak properly, Kat just gasped and sputtered in response, her eyes rolled into the back of her head.
Four hours later, and with no end in sight, Cassiopeia was dreadfully bored. "TALON!" she screamed at the top of her lungs into the house, the assassin flying out of the darkness, landing on one knee. "Kat is feeling ill, attend to her." she said cryptically, before slithering off. Taken aback at the strange request, he found a ridiculously strong slightly Purple Katarina fully naked and pinning him beneath her. "Shit." was the only word he managed out edgewise before she mounted his face, grinding against him hungrily.

The next day, Kat was back to her old self, a little sore, but relieved that the ordeal was over. Stretching herself out she passed Talon laying on the ground, his clothes in tatters and bruises all over his body on her way out of the house. "Don't spend all day laying there like a useless sack, Talon, there's cleaning to be done." "Y-yes Mistress.."
