Everyone was keeping her distance, until Alex approached his dog. Lucy appreciated his interaction with her, like any dog would. She nuzzled against him, causing him to feel flustered as she now had very human-like tits, two large ones where a normal woman's would be and two smaller pairs bellow, with the middles ones being a bit larger than the bottom. Everyone was recovering from the shock when Lucy actually spoke Alex's name. With some further prodding, they figured not only could she speak, she knew the names of everyone in the room, although her speech ability was similar to a toddler.
Kate was the most distressed of all, as Lucy's new form had awakened her lust and her pants strained to contain her erection. Despite that, she didn't yet feel like loosing herself like last time. She still had control of the situation.
Alex decided to take the new problem to his room, as Lucy some times refereed to his mother as "mate", and it was clear she was uncomfortable. Of course Lucy didn't want to be left alone again so he had to stay with his hyperactive half human-dog while everyone took stock of the situation. She behaved like a child, exploring her new surrounding with her new hands and eyes. The colors she could see now made her even more interested in objects she never cared about before.
Her owner on the other hand tried to avoid looking too hard at what he was seeing. Ignoring the fur, Lucy looked like a very sexy woman and that was already cause for an erection, but she was also naked and refused to dress up. As she was exploring the underside of his bed, he caught a glimpse of her pussy, triggering and unannounced orgasm with a grunt.
The smell of sperm had an immediate effect on Lucy, as she went from playful to horny. The shock of his orgasm had barely subsided before Lucy's nose was sniffing his pants, causing him to orgasm again. Lucy uttered the word "mate" again as she tried to remove the shorts from Alex. He knew he had to fight it, he wanted to scream for help but something was keeping him from it, some deep part of him wanted to feel the raw animalistic pleasure his mother felt as she plowed Lucy's do pussy not long ago.
Eventually Lucy's new hands won as the shorts were removed and cum sprayed all over her. She didn't waste any time cleaning herself, her long tongue was immediately put to work around Alex's shaft. At the same time he wanted to cry from pleasure but he was weary someone would hear and try to stop this, and he no longer wanted that to happen.
The more the bitch's tongue worked his cock, with dexterity no human could match, the less human it presented itself. His foreskin pushed back into a sheath, while the tip became more canine. A tail soon started to push from the base of his spine and his ears elongated and fell over themselves. When his cock looked like his mother's, Lucy stopped and turned around on all fours and presented herself to her other mate. Alex didn't hesitate.
Both of them had been quiet so far, but soon howls and moans alike filled the room, while Alex body was covered in fur while keeping a human male's anatomy. But would anyone interfere?
