"Is this a private party or can I join in?" Amy said as she stood in the doorway smirking, all three girls in the room turning towards her with blushes on their faces as the took in Amy's current form.
Amy's breasts had shrunk quite a bit, in stark contrast to the massive breasts currently sported by the females, however her penis was absolutely massive... and fully erect.
But Amy's ears were slightly different, they had a light coat of brown fuzz and they seemed slightly pointer, her finger and toe nails had started turning black but otherwise she was mostly the same as the previous day. "I think it's time I start breaking all of you in..." Amy said before putting her finger on her chin. "But who do I break in first..." She wondered before looking at Mark. "I want to save you for last... Victoria, get over here." Amy said, taking full advantage of her domination as Victoria nodded weakly, blushing all the while as she stood in front of Amy.
"No your knees." Amy said, Victoria getting down on her knees as Amy bent her erect penis and stuck it in front of Victoria's mouth, who quickly opened up and took the giant penis in her mouth, rubbing it as Amy moaned in pleasure.
Mark and Josh were left to watch as Amy ejected her load into Victoria's mouth, Victoria gleefully swallowing all the cum she could before Amy pulled her penis out of her mouth and walked around Victoria and grabbed her buttocks.
Victoria yelped in surprise as Amy thrust her penis into her vagina from behind, in a way the humans were not meant to do. But as Amy thrusted Victoria's vagina began to move. As both of them had their passionate sex, Victoria's vagina took the proper place for a doe, making the ordeal much easier for Amy as she ejaculated inside Victoria's vagina.
But the sex had caused changes besides that in Victoria as well, the fuzz around her vagina had grown thicker, and black had started to take her toe nails and finger nails, her ears had grown slightly pointed and had gained a soft coating of fuzz.
Both Mark and Josh had watched the sight mesmerized, trails of fluid from their vagina's slowly spilling down their legs from how aroused and wet they were at the sight of Amy's taking of Victoria.
"You're next Joshy... but later. I'm spent." Amy said as she pulled out of Vicotria, leaving the girl panting on the ground in sheer pleasure, bits of cum falling out of her vagina from just how much Amy had sprayed into her. "I can't wait..." Josh mumbled with a blush on her face.
