Lynn didn't seem to register a word Bree was saying to her. Her body felt so charged with sexual energy. She needed someone to relieve her. And the only source of relief was this massive equine cock in front of her. Lynn's udder continued to grow as she crawled on all fours to Bree.
Bree kept backing up, and eventually found herself walking in circles trying to keep Lynn away. Thankfully she'd managed to stay unaroused, so her changes had stopped. For however long she could hold out. Lynn's changes were getting more and more obvious, and that made it harder for Bree to resist the urge to let Lynn suck her off.
"Don't think like that. You're not some airheaded bimbo. You're not going to let this happen." Bree thought to herself. Bast meanwhile was still seated at the kitchen table. She smirked watching this game of "cat and mouse". Bree was an endless source of entertainment. And Lynn was certainly fun too.
"Enough of this game. Let's get things moving again." Bast said. Both girls caught the scent of something. Something... good. Something they wanted. Bree looked down and in horror and shame watched her penis slid from its dark home.
It seemed larger than before. Maybe because Bree was incredibly turned on by whatever that smell was. But her cock seemed thicker, and had a strong scent itself. Fully erect, Bree guessed her cock was ten inches now, dark with one large pink splotch right above the head. The massive organ flopped down smacking against true equine testicles.
But despite the pounding in her chest and the urge to do nothing but fuck, Bree held herself back. Clenching her jaw and pinching her tail did the trick. Though Bree was still getting used to the fact she even had a tail, let alone that she could control the appendage. She didn't know where that damn goddess was hiding, so she just glared around the room.
Bast laughed silently as Bree scowled in her general direction. There was a shuffling noise coming from another room, which told Bast her "gift" had arrived. She looked on as Lynn's body reacted to the stronger smells, from both the unseen visitor and Bree's musty cock.
The enormous udder waved back and forth in the air as Lynn's body reshaped. Her horns were much shorter than Bree's, as was her tail. But as she legs changed, Lynn grew several inches taller. The nails on her feet were quickly overtaking her toes. The black keratin spread all over the tip of her foot. Her ankles, soon to be fetlocks, cracked as the bones in her feet rearranged themselves. Five toes became two thick digits.
As Lynn's feet became hooves, her body gained mass. Her thighs bulged with muscles to support her large frame, and the orientation of her legs changed. Lynn didn't even register the pain. The smell coming from the other room was drawing her in. But she couldn't move just yet, as her feet hadn't finished their transformation into proper hooves.
Her upper body began to shift now. Her horns had completed their growth, and now the spell was working on the rest of Lynn's head. Changing her ears and nose first. Pulling them out, causing a fine layer of light brown hairs to pop up form her skin. Lynn's upper lip fused with her nose, which had swollen and pushed further from her face. The snout was only three or so inches long.
Though she already had large breasts, Bast let the change enhance Lynn's bust even more. What were originally human DD cup breasts ballooned to F or G cups. And then they swelled with milk. The fluid added an extra two cups alone, leaving Lynn with an udder the size of a pregnant woman's belly, and I cup boobs. The nipples and teats on each looked like hot dogs, pink and thick, dripping thin trails of white onto the floor.
As Lynn's transformation came to a halt, the figure in Bree's dining room emerged and showed itself. Bree had managed to keep herself from changing up until now. Now, she was solely focused on letting this "guest" in her home ride her until the cows came.
