Both of them become your mom and your sister.

Claire’s body grows rapidly. Her breasts shoot out of her chest as they grow to E cups and sag slightly as she gains age. Her hands become long and wrinkly while her face gains crows feet, laugh lines, and wrinkles showing much more age than Mrs. Bradley. Her hair becomes straighter and changes to a blonde mixed with streaks of grey. Her stomach pushes out into a slight muffin top while her legs and butt fill with cellulite and her hips widen to childbearing proportions.

While Claire becomes the mother “Mrs. Bradley” begins to shrink into the daughter. Her signs of age disappear while her red hair becomes blonde. Her toned muscles slip away as her proud breasts shrink to a perky C cup and her ass becomes smaller but rounder. Her hips stay wide enough to give her a sexy shape that compliments her now very thin waist and flat tummy. Her face finally shifts to your slutty sisters with puffy lips, dainty nose, and bright blue eyes.

“Like, that seems so hot mom. I’d love to!” Your shapeshifter girlfriend says as she begins to suckle her “mother’s” breast.

“I’ve got plenty for you as well big boy.” Claire says hefting her other leaky breast for you to feed.

In a horny trance you walk towards your mother and grab hold of her large tit and begin to suck as Claire kisses you on the forehead and bites her lip in ecstasy.

“Oh yes children! This is what mommy loves! I love you so much!” Claire shouts as you move to makeout with Claire and your “sister” begins to eat her pussy.

You both pleasure Claire as if you were her servant with you giving her a taste of her dick. Eventually you get ahold of your “sister” and get some action with her as your mother gives you the taste of her titty again.

When all your energy is spent your shapeshifting GF and you collapse on top of Claire. As she strokes your and her bestie’s hair just like your mother, she asks:
