Make Kim into a tasty treat for some tentacles...

Kim looks at her sister, totally befuddled. "What? Begin what?" She doesn't notice the slender, elongated entities rising quietly out of the bathwater behind her.

Jenny stays silent, instead waiting and watching as a dozen horrific purple tentacles ascend from the tub. They hang in the space of the shower, their tips angled just downwards at the unknowing Kim, ready to strike at any moment.

"They asked for you personally..." Jenny says, cryptically.

Kim doesn't have time to ponder the statement when she suddenly finds her limbs restrained. "What the...??" She screams out in panic as the gelatinous arms wrap around her body; her terror-stricken heart feels like it's about to beat right out of her chest.

"Oh God!" Kim cries, "What's happening?" She on her sister for aid, but Jenny simply looks on, the small suspicious grin she wore before now a full-fledged ear-to-ear smile.

Kim fights for her life, but is unable to move against the strength of the tentacles attached to her limbs and neck. She closes her legs instinctively when she feels one slowly creeping up her thigh, leaving a trail of thick mucus as it climbs.

"Jenny? Jenny!" Kim hates her sister with every passing second that she does nothing. Even now, all Jenny can do is smile, and approach, ever so slowly. "Jenny you fucking stupid bitch, help me!!"

Jenny just shrugs off her sister's profanity. "Ohh Kim..." she sighs, "I try to do something nice for you and this is what you say back? Tsk tsk..."

With all her might, Kim tries to resist the rapacious tentacles, but it's no use as her thighs are slowly pried apart, the one tentacle wiggling its way closer and closer to her nether region. The other muscular tentacles lift her completely off the floor, holding her legs far apart and displaying her naked body in the air like a butterfly.

Finally, the encroaching tentacle reaches Kim's pussy, rubbing its head against her clitoris and leaving its slimy ichor all along her snatch. She is too disgusted to look at the thing rubbing and grinding along her delicate folds.

As if that weren't enough, a pair of thinner tentacles converge on her breasts, rounding her soft mounds a few times before arriving at her nipples. There the tendrils play, flicking and pinching her with their surprisingly agile tips, until her own pink tips become stiff and sensitive. Kim pushes aside the part of her that is somewhat turned on by this sick foreplay.

"Oh? What was that?" asks Jenny, as she catches her sister closing her eyes and leaving her mouth agape. "Are you enjoying that? You looked like you were having fun there." Kim quickly denies her sister's query.

"Shutup you bitch!!" she snaps. "You fucking, crazy b--ahhhh!!" Kim screams, throwing her head back as the tentacle just slightly inserts itself into her lubricated pussy. Jenny laughs delightedly.

"Oh you do like it, don't you? It barely touched you!"
"What the fuck are you talking about? It's fucking impaling me!" Kim shouts back.

Jenny gives a look. "Are you sure? You should see it for yourself." Then Jenny comes close, close enough to smell her sister's wet cunt floating in mid-air. "Oh and you're wet, too. So so wet...it's flooding, my dear sister..."

"No it's not! That's slime!"
"We'll see about that."

Just then, the tentacle begins to push deeper into Kim. When it has gone as far as her her body will allow, it retreats, only to return an instant later, plunging in and out of her, faster and harder with every thrust. The friction sends waves of pleasure all over Kim's body, her hardened nipples, sopping-wet pussy and flushed-red face no longer able to hide her ecstacy.

"Oh God!!" she cries, throwing her head this way and that, her mouth wide open and drooling.

"They get cold easily, Kim. I drew them a nice hot bath but they just weren't satisfied!" Jenny explains incredulously. "I think they like you, Kim. You look like you like them too, now." Despire her pleasure, Kim curses her sister in between her uncontrollable spasms, letting loose with an obstreperous tirade. Jenny just can't believe the little brat's stubbornness.

"You never listened to your older sister, Kim. Like I used to tell you, if you haven't got anything nice to say, don't say anything at all." Right on cue, a large, fat tentacle dives into Kim's open mouth, silencing her protests and cruelly fucking her throat. She gags on the grotesque arm, making every attempt to turn away or bite at the alien violator, but to no avail. This time Jenny puts her hands on her hips, giving that "how could you?" look.

"Kim! That's no way to treat a guest!" she scolds. Then she removes her glasses and unties her long brown hair.

"Here," she says, "let me show you how."
