Not happening

Her hands moved with a mind of their own, toying with her nipples and clit. That small, rational portion of her mind screamed for her to stop, momentarily winning before the Treant calmly interjected another one of it's vines into the equation, reaching through the hole in her pants to slip inside her asshole again. She moaned at the fullness in her ass, her hips bucking against the vine holding her as she tried to get more of the one in her ass inside her.

The rippling sensations of pleasure rolling through her silenced the small voice of logic in her head, her lust overwhelming her again. She spasmed again as another small orgasm rolled through her. She failed to notice the Treant had started moving again, carrying her to parts unknown.

The Treant smiled again, Venus barely noticing the jagged maw in front of her, before it finally spoke. "The druids will be pleased. You're a most worthy candidate." The tiny voice in her head raged at that, demanding to know what she was being chosen for. For a brief instant, Venus almost came back to her senses, realizing that something was sorely amiss, before that thought abruptly ended in a wall of pleasure.

What had stopped it was the arrival of four more Treants, all of whom had joined the first one in caressing her with their own vines. Every inch of exposed flesh had vines attending to it, from her shoulders to the soles of her feet, and the sensations were positively overwhelming.

She rolled her head back, her eyes shut, and let the sensations roll. Something large pressing against her lips made her eyes open slightly, before the flew open in surprise.

What stared her in the face was a massive, green cockhead, attached to a long, thick vine. She gasped as she looked at it, and the cockhead took full advantage of her open mouth to fill it. She gagged, surprised at how forcefully it had entered her mouth, before her head began bobbing back and forth. Her gag reflex kicked in the first few times, but was rapidly suppressed by her continued effort to deep-throat the monster cock. Amidst all that, she felt two more massive members **** themselves into her steaming twat and somewhat-ready asshole, where they began rhythmically pumping in and out of her. Her squeal as her hymen tore was lost against the enormous member in her mouth. She and they quickly established the pace, moving in unison against each other. Two more enormous vine-cocks found her hands, and she began stroking them off.

Her body was so over-sensitized she was no longer thinking, her body responding on pure, primal instinct only. To the untrained eye, it seemed she was a master whore, one used to pleasuring multiple men at the same time.

Orgasm, for all six of them, all came at once, in one, massive, unified howl, all the vines except the ones on her waist releasing her. All five Treant cocks twitched, spasmed, then blew their loads. Venus choked on the deluge pouring into her throat for a moment, before she simply began swallowing it out of sheer reflex. More titanic loads filled her pussy and ass, so large they began oozing around their respective dicks before they were even done shooting their loads in the first place. The other two coated her in even more cum, matting her hair, and liberally pouring across her torso and thighs. Her own orgasm was so powerful it actually propelled some of the incoming cum out of her. She spasmed and twitched her way through it, her primal scream lost amidst the cum pouring into her gullet from the cock in her mouth before she passed out from the sensory overload.

The Treants removed their slowly wilting members from her body, retracting them back towards themselves as they continued their journey...
