Mia always held a fantasy of having wings, to be able to fly, and this had been redoubled as she had found out about harpies. She was an intense fan of the avian monster girls, and now she was one, with larger tits atop that. Yet, her tastes had prior been vanilla, having never slipped into the idea of a harpy being fucked by another woman, much less a futanari. Though if things had continued as they were, she would have soon found her attraction to the look of harpies was also founded in a taste for the female body and delved into yuri, and her bisexuality would have discovered futanari then.
But the breakdown of the Chronovac and the transformation wave meant she never had this gentle introduction. She was rocketed straight into a whole new realm of sexuality she had not known existed. She had been shocked and confused, at first, but now, as she bounced atop one futanari harpy, made out with another, and had a third pounding between her breasts? She was in a new heaven. Any strangeness of the bodies was not just accepted, but began to be desired.
And in the face of this, she threw herself into it, flying right past any strangeness with the oddly transformed bodies and even soaring to the point she found them more attractive. Her orgasm would come swiftly, the clamping down of her pussy throwing the four-legged harpy fucking her reaching her own orgasm, filling her with one cock while the other shot cum over her and the twin-cocked harpy's bodies. With the two reaching orgasm, the others pushed themselves faster, and soon the dick-nipples harpy shot loads of cum into the duo bouncing atop her breasts, the cock-head harpy came into her kiss with Mia, and the twin-cocked harpy spilled her load across Mia's breasts.
One round was not enough for her. Nor would be the second where she was fucked by the nipple-cocked harpy. Nor the third where she was being eaten out by the three-breasted harpy as she made out with one of the three-headed harpy's heads. Nor the seventh. Nor the fourteenth. And the ever increasing rounds was not enough for the other harpies either.
Cum from the many cocks or pussies and milk from breasts, slickened their bodies and soaked their feathers, drenching them utterly. And still they fucked. Exhaustion was but a distant and potentially unreachable idea, and sustenance was unneeded, both thanks to the changes rendered to their bodies by the broken Chronivac. Sex was gifting them energy that maintained their lives now. But even if any noticed this was true, it would be but a passing joy in the face of orgy.
