Penetration gets doubled

The sprouts were accelerating slowly and had not reached an overly fast pace when something happened that caused Casey to open her eyes wide - the anal sprout had gotten company. Another “penis” of a similar girth approached her back door and was pushing itself in, it tried to be gentle, but double anal penetration by two thick penises can never be truly gentle. Casey issued a long low groan as her sphincter was being slowly stretched. Once the sprout got in it joined its companion in the penetration, although they moved completely out of rhythm with each other. The bulge on the woman’s belly became more prominent as it moved up and down on the front of her body.

Casey did not receive any chance to at least partially regain composure, because her vagina soon met the same fate as her anus - another thick “penis” gently pushed itself in, causing the woman to cry out in unexpected albeit rough pleasure. The other sprouts changed their approach too, the suckers increased the pressure and intensity of the stimulation on her nipples and clitoris, the thin ones coiled around her breasts became more active as well, squeezing them more tightly, then releasing their grip, all done at a faster pace; Casey felt that she was nearing an orgasm. It took only several more moments of the multi-pronged stimulation before the woman climaxed, it was an exquisitely intense sensation, Casey’s body trembled in her organic bounds, she issued loud ecstatic moans and cries, her anal and vaginal muscles clenched, but with the thick intrusions never ceasing the relentless penetration the clenching meant little.

Apart from the earlier intensification of the stimulation the sprouts altered nothing when Casey climaxed. They also continued to shoot moderate amounts of their lubricating fluids which had more positive effects as well - they increased the durability of the skin of the tender parts through which they were absorbed, they improved the woman’s overall stamina as well. Both features of the fluids were necessary, because the sprouts exhibited no intentions of stopping, they only halted accelerating for the duration of Casey’s orgasm.

When the climax subsided the woman was breathing heavily, when she calmed down she resumed the moans and cries, the multi-pronged stimulation was still pleasurable after all. But she received only several moments of such “active rest” before things were taken to a higher level. If Casey had thought that two thick “penises” per hole were a lot, which they definitely were, she was in for a shock, because a third pair approached her and began to wiggle their way into her body. She again issued a long low groan which soon turned into a high-pitched shriek as all of the “suckers” increased their pressure. The two new sprouts slowly pushed into both of her holes at the same time, they were just as thick as those already present and stretched her orifices beyond levels she had imagined possible. But they caused her no harm, sure the crazy pleasure was accompanied by discomfort, but it was bearable and not painful.

The two pairs of sprouts ravaging Casey’s anus and vagina never ceased the penetration, so the moving bulge on her belly slowly grew larger and its motions became more chaotic. The third pair eventually got as deep as it was possible in the crowded space, but still they never formed a rhythm and each continued to move back and forth in its own pace.

Casey’s clit was large and swollen from the constant sucking, it had also gotten incredibly tender; the “sucker’ worked a bit like the pump sex toys, only significantly more sophisticated and versatile, it also seemed to have a consciousness of sorts, or at least the creature that it belonged to, had. The woman’s nipples were also erect and swollen beyond their usual size, her breasts kept their firmness although they were being constantly groped, squeezed and pulled by the thin plain sprouts.
