Nesting Instincts

Stacy's body ached after she birthed a new clutch of eggs. She could feel the physical toll this was taking on her, but she felt an overwhelming hormonal drive. She could barely think straight when she wasn't squeezing the wriggling eggs out of her taut belly, let alone when she was. The slightest thought could send her into a sexual frenzy, spurred on by the other creature growing inside her. Stacy got up from the slime covered tub. Her legs were shaky, and she leaned against the tile wall for support. The water had been running for a while and she rinsed some of the residue from her. The cool water helped her mind to clear, but the tank was running out of hot water. She needed to keep her eggs warm until they could hatch She saw Alex and another boy passed out on the floor, each exhausted from the depraved madness that had overtaken all of them. Lena was waiting patiently in the hall, and Stacy wondered what to do with her

She stooped and tried to play with the passed out boy, semi embedded in the alien goo that was now the floor. He was as limp as could be, and not waking any time soon. Stacy stood again and gave Alex a kick with the side of her foot. He too was near comatose, but he stirred a little. She needed food and her stomach growled in protest.

"Lena get food." She commanded. Her sister wordlessly stood and went to the kitchen.

Stacy turned back momentarily to pluck a few of the fragile orbs from the cool running water and followed Lina to the kitchen. Her sis stood at the counter chopping veggies. Lena was commanded to feed her queen and she was preparing a feast. Stacy couldn't resist the call of her sister's pert backside. She crept up behind the distracted girl, and hugged her; sensually running her hands around her mid drift and over her hips. Lena coed slightly as Stacy ran he free hand over her slit. Lena was already wet and Stacy's touch assaulted her addled brain with desire. She needed to cum, the creature sharing her mind needed to cum; no that wasn't quite right. She needed to serve. The thought exploded in her delirious mind like a thunderclap.

Stacy leaned in and bit Lena's ear, it was playful and aggressive at the same time, and she began to press the teen's upper body forward onto the counter. Lena couldn't resist her sister if she wanted to, and she began to spread her legs to expose her now drooling slit.

Hold onto these for a while." Stacy whispered into Lena's ear. Keep them warm and safe. Lena struggled to think as Stacy's hand worked her slick clit. Then a pressure began to build at her entrance as Stacy pressed something into her wet snatch. The orbs were big, but she was so ready for them. Each one that her sister pushed into her drove her closer to ecstasy, and waves of pleasure crashed into her as each bump pushed up against the last and slid further into her. Then Stacy said something.

"Be a good little incubator, you dirty slut."

And Lena came.
