She welcomes them into her pussy.

Unihibited, Jenny slid her white floral nightie off her shoulders, shedding it from her body callously like a snake. She took one step forward and stood unnaturally straight, jutting her large breasts forward and showing off her tanned, slim body for the tentacles' enjoyment. Kim had no idea whether the slimy appendages could -see- her sister posing like that, but apparently she had their attention somehow.

As a dozen tentacles hungrily ravaged Kim's body-- fucking her pussy, her mouth, and rubbing themselves all over her sweating skin-- a dozen tentacles more emerged from the tub, immediately rising into the air and training their curious tips on Jenny. Jenny saw them and giggled.

Without hesitating, Jenny peeled off her pink panties, tossing them aside like she'd never wear them again. Then she took a seat on the floor, opening up her legs as wide as she could. Kim saw her sister's hairless pussy for the first time since they were kids.

"Now watch this, Kim," said Jenny, as she leaned back on one hand, and began touching her lips and clit with the other. She felt the slickness between her fingers, and purposefully did so very clearly so that Kim could see. "Oh, I got all wet watching you, Lil Sis."

Then, Jenny put her hand back on her pussy and rubbed her hot button, making herself wetter and wetter. "Ooh, ahh..." she cooed, "come, my Dears..." The tentacles somehow heard their cue, and converged on Jenny's eager form, wrapping her up like Kim, but with a much greater degree of freedom. Kim noticed this and wondered why.

Jenny soon provided the answer as she took her slimy fingers and pried apart her own lips, welcoming a particularly girthy tentacle into her canal, where it proceded to fuck her, much to her delight.

Two tentacles vied for the right to Jenny's mouth, but she seemed expertly prepared for this situation. With one in each hand, she alternately sucked on the pair, blowing one while masturbating the other until it too had its turn in Jenny's warm, moist, inviting mouth.

Kim looked on, still floating in the air, quite amazed at the sight before her. How did this happen? she thought. It was hard to entertain any other queries, however, as her mind was being taken over by pleasure. As feisty as she had been, she could no longer deny that she was loving every moment now: every moment that she had this alien flesh coiled over her body, every moment that the big tentacles were inside her body, fucking, pulsing, and depositing their sticky slime, which-- she came to realize-- was the most wonderful thing she had ever tasted.

It wasn't long after that Jenny was lifted into the air as well, so that the tentacles could reach her from any angle. She moaned huskily as the lustful arms took advantage, rubbing her thighs and breasts with their slime, enveloping her in an arousing musk that drove her wild. And so she sucked-- gripping a tentacle and gliding her soft lips all over its head, caressing it with her tongue-- and fucked-- gripping another tentacle and pulling as much of its thick head into her cunt. Pleasure was mounting, and Jenny couldn't stop herself from spasming. The tentacles seized her hands and held them up over her head. They would be in complete control, now, and they wanted more from this pair of horny ladies.
