////Tie Up "String her up with her own tendrils and fuck her." pp needed
The jelly-girl quivers, her gelatinous [jellyColor] membrane jiggling in the water as she tries in vain to tangle you in her mess of tendrils. You take hold of the gooey strings, feeling them pulse in your grip, noting how sticky and pliant they are. A cute, pitched squeal escapes her as you pull her squishy little frame, looping and tying her own  appendages across, between, and all over. Knot by knot, you fashion them into a crisscrossing web that pulls her limbs up, arching her back, accentuating her small, supple form. The bindings shimmer in the [sun]'s light through her natural translucence, and the jelly ropes form an intricate harness that hangs her from her bell like an ornament.

Her curious eyes blink in bewilderment. Perhaps the amorphous quality of her membrane would let her fix this predicament if you gave her the time to dwell on it, but you [if (isTaur) {mount her, straddling the cushiony umbrella while thrusting blind for her squishy mons|slip behind her, [if (isnakedlower) {pressing your [cocks]|bringing your [cocks] to bare to press}] against her soft, squishy mons and tiny ass}]. The permeable nature of her body may just make your choice of where to fuck arbitrary, yet as you grind your tip into the slimy vulva, there's what could be described as an underwater [i:purr] resonating from her. You feel your dick[if (multicock) {s}] stiffen even more, somehow, and [if (isTaur) {you hold her steady with your [legs]|you sink your fingers into the plushness of her little butt for leverage}] before thrusting hard. The jelly-girl shudders as you [if (cockLength>5) {impale|penetrate}] her stretchy, slick pussy. Her insides conform to your shape, matching the [cocktype]'s every contour and detail. The jelly ripples in waves at the point of entry the moment you slam to the hilt.

She writhes--not to escape, only in an instinctive attempt to squeeze down on the intrusion[if (cockArea>=8) { bulging and warping her [if (allowbaby) {baby-like|puny}] body}]. The ropes of her own tendrils stretch and flex with her movements, keeping your sex-sleeve in place as you pump into her. Her slimy interior quivers along your length, grasping with need, and her restrained form trembles with every deep thrust into the jelly. You slide your dick in and out, moaning under the sensations, and then [if (isTaur) {squeeze her tightly between all four legs, mushing her bell around her like a cocoon[if (isCentaur) {--or dummy mare}]|sink your [face] into her bell, muffling your noises in its plush embrace. Your [hands] explore her, grasping the [if (silly) {chibi|pint-sized}] mimicry of a [if (allowChild) {[if (allowBaby) {baby|child}]|woman}]'s figure and compressing her [if (allowChild) {flat|palmable}] chest under the needy strength of your digits}].

Her body clenches down, pulsating wildly around you, signaling her climax as she shakes and quivers. You drive yourself harder as she twitches in the web of her own tentacles. The vibrations of her orgasming inner-membrane roll across your [cock], and it isn't much longer before you tense and gasp. Semen bursts from you, rapidly mixing into her fluid mass. Even as she goes limp, her body continues to ripple, squeezing your sensitive member for every [if (cumQuantityLow) {little|[if (cumQuantityHigh) {gushing|thick}]}] spurt you can give her.

Content and satisfied, her cohesion weakens, and all her tendrils meld with the rest of her gooey skin. You elect to pull away before you get stuck to the amorphous slime, collecting yourself to be sure nothing got left in the sticky mess.
