CHOCOJENNY TENTACLE

Snaking their way around the Jenny’s posterior, the alien beast sizes up its prey…
Having been ambushed by the otherworldly creature while changing into a slimmer outfit at the beach, Jenny can only whimper and tremble as those thick, sensual tendrils outstretch towards her. Feeling her servos strain and mocha-colored body quake all over, the sexbot-turned-robogirl can only brace for the worst as the slickened tentacles rise into the air above her ass, taking in the sight of her tremendously sized, velvety soft asscheeks , so perfectly round and plump, looking naturally polished and utterly inviting to say the least. The writhing appendages snake their way up her luscious thighs and outline her ass, finding it to be perfectly, obscenely large and with a quick prodding against the surface which leaves Jenny almost squealing from fear-as soft as marshmallow fluff all the same. One of the largest asses they’ve ever come across in fact hers is, so decadently soft and plump, giving her rump a small slap with one of the smaller tentacles and watching it bounce and jiggle, enacting a silent moan to get caught in her throat as they begin to toy and tease her asscheeks.
Jenny’s mouth gapes open and eyes roll back, a pure state of ahegao strewn across her face as those slick, slimy tendrils grope and fondle her profoundly large backside, hugging one asscheek and then the other, spreading them apart then letting them wetly slap back against one another, creating an audible *squelch* that leaves Jenny cringing but obviously enthralls and amuses the beast manhandling her ass.

Oh if only she knew what was in store for her fat tush.



Slowly but surely, the tendrils wrap around her legs at the base, keeping her nice and imobile while corning every exit in case she were to make a mad dash for the door (of course in her state of being so compounded by lust and fright there was no chance of that happening anyways) . The ones at her ass begin to softly knead against her rear, drenching it in an oozing excretion of slime that coats her rump like a fine lube, those two massive asscheeks looking so radiant and glossy in the dim light while she shudders and shakes. They treat her rump so carefully and precise, making sure she's not in any discomfort while they affectionately brush their feelers around the sides of her gorgeous chocolate ass. As she loses herself partly to the arousing feeling of being completely dominated by the jellythick, pulsating creature, a faint whimper can be heard escaping her mouth as tentacles wrap around her arms, leaving her completely and totally at the mercy of this horny beast encroaching upon her rear.

Finding it so easy to subdue her though, the tentacle creature drops the facade and roughly wraps around two of the thinnest tendrils around each buttock, heaving those tubby, gelatin-like buttocks to either side while she lets out a shrill groan, moistened slit and asshole completely exposed and the tentacles squirming at the sight of her soaking wet nethers.

The creature wastes no time in foreplay now as opposed to earlier, losing every bit of decency within its undulating body as it raises a single slicked, oily tendril in the air, swayin from side to side and dripping the natural greasy substance which coats its entire expanse.

Within seconds, its already come within but a few inches of her ass, hesitating for a single moment as Jenny catches her breath, before then diving into her rear.
It dives deeply into her asshole, shaking her asscheeks like two tubs of chocolate jello while it snakes and slithers its way all around her rump, her lips parted as she howls in the partly-painful, pleasuring bliss overtaking her body as the rubbery extension writhing about inside her ass pushes her past her limit. It squirms around inside her ass and vibrates intensely, lubing up her rear in the process of going so deep it nearly leaves her fainting right then and there. Thankfully, it soon begins to pull out of her ass..only to then dive in again while her buttocks are let go by the other slimy arms, both asscheeks grinding against the massive tentacle dragging itself out of her ass. She's only given a few seconds to collect her thoughts before it dives into her ass again, going incredibly deep like before but doing so incredibly quick, gaping out her ass while the lube-secretions allow her rear to be fucked as long and hard as the beast desires. Soon, Jenny's entire body is bucking back and forth as the oversized tendril works up a steady tempo of thrusting into her loosened ass then pulling nearly all the way out again, fucking her tender rear to the point she's almost drooling as her synthflesh asscheeks feel so tremendously sore after just a few minutes of this powerful fucking.
