Fuck, she was cute the way she was trying not to make any noise as he fingered her, alternating between plunging inside her and trying to find the right spot to make her gasp. Trying. He was a little too drunk and clumsy not to need some guidance to consistently find it.
She was grinding against his dick though, and he was so hard for her, and his dick was bumping up against his fingers as he worked. Maybe he could just pull the fabric aside...
