Ty was surprised that the two girls liked him. He thought back to his interactions with the two and they always seemed to be near him when they could without making it obvious as well as acting somewhat nicer though not to noticeable for all their interactions were around others that didn't like him too much thanks to Dustin and his friends making things harder on him while the other boys who were his friends were ok they did seem to try to keep the girls from him for some reason. A quick glance into their minds showed they were telling the truth so he removed the mental effect he had planted earlier due to them being unneeded. He removed his clothes before stepping up behind Lisa his cock harding as he willed it to double in size from 5 inches and made it so no sound will leave the house along with no one to come over to the house till tomorrow. He grabs the two and pulls them into the main bedroom as they understood why he did so and they got on it on their hands and knees before looking at him with lustful looks as their new tails hanged high.
"I always liked you Lisa, Wendy, never could tell you thanks to Dustin and his friends and the trouble they would have caused us. I would have to choose one of you two only as well due to social norms." Ty said to the two as he lines up and pushes into Lisa stopping half way in. She whines as Ty takes her virginity as he starts to pull back before thrusting back in slowly to let her get used to him. His left hand moves to Wendy's lower lips and fingers her as not to leave her out, making her yip in surprise before moaning. Ty grunts as he speeds up as Lisa devolves into yips and moans as Ty's thrusts went deeper and harder into her for several minutes before he grunts giving one last thrust into her hitting her womb and cums flooding it and her pussy as she climaxed as well from it with Wendy doing the same a minute later from Ty's fingers.
Ty pulled out of Lisa as she slumped down panting before he moved behind Wendy before lining up and thrusting into her as well. Wendy yipped and moaned as Ty started off like he had with Lisa before she spoke up. "Faster, harder please! Take me like the bitch you turned me into!" She begged him. Ty decided to do as she asked and went harder and faster into Wendy as she moans loudly in pleasure as he takes her virginity. Soon she climaxed hard howling loudly in pleasure making Ty cum as well into her cunt as it tightened on his cock milking him for all he was worth. 'I'm glad I took precautions earlier he thought to himself as he pulled out of the wolf girl before falling in between the two of them, they had left some room for him. The two girls hugged him as they laid together for about an hour before Ty pulled himself up.
Ty thought to himself for a bit as the vixen and wolf followed and laid their heads on his chest thinking on what to do next. He wished to house to never run out of room for those living in it similar to the Tardis but expasioning only when needed and those not living in it won't take notice of it but still find their way through it if needed for what over reason. He looked down at his girls. "If you two wish you can stay here with me. I can make it so no one will pay too much attention to it and if we skip school that too while what we would had learned on those days and any tests and quizzes will be at B for grades if we don't do them even if we are at the school but not in the classrooms. I can make it so you can change forms from human to what you are now and back or make it as far as anyone else cares you two have always been like this even with fully human parents." He tells the two girls. They thought about it for a couple of minutes as they looked at each other before coming to an agreement. "We both want to stay like this and with you and the school thing we don't care much about it but will take the grades anyways." Wendy speaks up with Lisa nodding in agreement. "We also won't mind you adding more girls as long as you spend some time with us." Lisa speaks up this time. Ty smiles at the two as he pets their heads and mentally wishes the changes into place. He then felt a pair of hands on his cock making it start to harden again and looks to see the smouldering looks on the two girls faces showing they want some more fucking.
