Squip's manipulation had been the start, the spark inside of her, but it isn't entirely what fuel's Justine now.

She see's the way that Connor looks at it and experiences the way he feels about it. Justine had given Connor her heart long ago, so why not offer the same affection to what Connor cares for as well. It is hard at times but then there are moments like these, where she can feel Connor's frustration and a wickedly pleasant thought comes to mind.

Her lips tug into a teasing smirk as Justine pressed herself more firmly against it. Her fingers brush along it's jaw before running her nails over Squip's scalp. Her lips hover against it's and she speaks in a sultry teasing note.

"We should have a little bit of fun."

i.e. teasing Connor.

It would be a good way to ease the tension in the house and a pleasant distraction from her own chaotic feelings as well.
