First some experimentation

You decide to have a little fun before approaching the woman and at least for the moment maintain your form as you had just gotten these powers and morphing yourself seemed like an unnecessary risk.

You find a douchy looking guy in the gym and use your mind control abilities deciding to try and set up a funny and sexy situation. You pick this guy as he was with people but has split off on his own hitting on women away from his douchebag friends. You make sure everyone ignores anything he you or Pia does and smile as you see Pia is slightly bigger than him as she smiles flexing in the mirror practically ogling herself.

You have the douche walk up toward her putting the idea that he should hit on Pia into his mind and leaving the rest up to him. The man walks up to the giant of a woman and slaps her ass, you did amp up his douche factor a little. He proceeds to speak as Pia stands a little surprised but also a little too taken in by her own reflection. “Hey baby that’s a nice tight ass you got there some nice tits too and damn those are some dick sucking lips Want to go have a good time somewhere more private”
