And once he pulls over he no longer needs to keep his eyes on the road so she can have her lips on his.

Kissing!

He could get used to this. 

Good, that's exactly what she intends.

She should probably get inside eventually, but he seems too distracted to consider this.

She seems to not want to bring that up, either. Making out: good.

Wandering hands: good?

Wandering hands are Stiles-approved!

Oh, that's good, then. And these pesky clothes between her hands and Stiles' skin, she should maneuver so it's her hands between his clothes and his skin instead.

He doesn't want her to feel left out, here.

Are his hands allowed to wander too?

Of course they are, reciprocation is the basis of a good and healthy relationship!

So reciprocal. Very, very reciprocal.

Should they be moving the festivities elsewhere? 

Mmmm possibly, but—

—it turns out Ade's mother is home.

Hello Ade's mother this is a very polite boy who hasn't done anything untoward today hi.

"Hi."

She has very obvious scars on her face, like an animal savaged her, and her right eye is completely white. "Hello." She looks at her daughter with a half smile—whether due to the amusement or because half of her face can't move is unclear. "Having fun?"

"Yeah, but I think Stiles should go home now, probably."

"Sounds good. Nice to meet you. Bye."

And he leaves. Without a goodbye kiss of any kind.
