You pull out your long tongue out of your own sister, while still keeping the blue phallus with all its tendrills deep inside of her pussy filling her with a strange blue liquid making her moan in bliss.
You keep your eyes on Katherine when suddenly, you hear your sister's voice in a sexy tone saying to your own mother. "Come on mum, relax. You work too hard, have some fun with your own daughters. You know you want to, look how much fun we are having. You're just dripping to join us." Her voice drips with sex that even turns you on.
Her blue alien blue eyes are added to your stare as the two of you try to bend your own mother to your will. Katherine licks her lips as she looks at the two of you going at it. The shine of your eyes mollifies her mind as she begins to cum just from the sight of the two of you fucking away.
Her knees buckle and she falls slowly to the floor at the erotic sexual things the two of you are doing to each other as you turn your own sister into a Siluran Sex Drone just like you are now in order to take over the world.
The fact you're blue and bald with skin that shines with a phallus is so erotic to her now, it only adds to her own desires as she watchs her other daugher slowly change into the same as you right before her very eyes.
Not to mention the fact her mind is locked by both of your desires to keep her watching as you finish up the changes in Claire so you or Claire gets your own mum to change next as long as she can't break free of your two wills. |
