Ty examines her new self in the mirror. using her hands to cup her breast, enticing the nipples. This caused her new slit to throb and get wet. She start to finger herself but than decides it would be better to experience the full sensation of womanhood.
She wonders if her adoptive family would ever accept her as she is now. Thinking it would only make matters worse she decides to leave. But not before I get a good fucking first. She starts to head to Dustins room when Sam the family dog enters the rooms.
Tail wagging, Sam a golden retriever sniffs the new Ty. With a silly grin she gets on all fours and wags her rear end in front of Sam. If the family won't accept me, than I'll just become Sam's family, she thought. Sam taking this as an invitation mounts Ty.
Ty's pet dog was inside her and it felt great. She noticed that
something was happening to her body as she met the thrusts of her dog. Looking at the mirror, she noticed the tip of her petite nose was black and wet. She watched her ears become hairy and grow longer until they flopped over hanging down the sides of her head. Ty saw a hairy tail creep down her thighs. She saw what was happening, but didn't stop the mating it felt wonderous. Her tongue was growing long, and hanging out the side of her mouth between her sharp canine teeth.
Ty watched her beautiful womanly figure disappeared in her mirror. Her breasts shrank and a row of teats lined her underside. She howled with pleasure as Sam her Golden Retriever stiffened sending his seed into her womb. Ty looked in the mirror seeing a collie still joined to her mate until his knot deflated.
After Sam got off her, the rest of Ty's changes happened at an accelerated rate. He face elongated into a muzzle. Ty's legs snapped and reshape, becoming fully canine. Her hands a arms soon followed. Bone structure reshaped to that of a canine.
