Give in.

Taking the sharpie you go to write on your mom but its dry.

"Good boy, you passed my test. Here is a working sharpie to claim the bitch with." Alex cackles.

Rolling your eyes you make your claim on mom and she freezes up.

"You can use me body as you normally do mom." you order.

Mom relaxes a little but is still clearly tense from the situation.

Alex comes over and sits in your lap, "and now we can be together forever with no outsiders getting in the way of our love baby." she says as she kisses you. "You can even use the meddling bitch however you want, I won't stop you."

You smirk, you know Alex does make a good point. "Mom pin Alex down."

Alex freaks out but before she can do anything mom has tackled her to the ground. "Wait baby, we can talk about this. what are you planning on doing"

You start walking to the frantically formed pile "Well, im planning on using my power." you begin lowering the sharpie to alex's skin

Alex starts freaking out, thrashing about desperately trying to free herself.

"What was that about you not stopping me? cuz it seems to me you are trying to stop me from writing on you. Mom hold her arms still."

Mom after moving about a little manages to pin he arms to the ground not giving her any room to move em.

"PLEASE DONT DO THIS!!!" Alex is now crying. It doesn't matter though.

If she can use your power as she liked then the owner of the power can do so much more. Pressing the sharpie to her bicep you begin to write "Josh Gillian’s ****".
