Good son: silently trace your fingers along her buttcheeks
From Create Your Own Story
You try to be silent and slightly touch her ass with the tip of your finger. Siri startles from you touching her and sits up immediately.
"Oh it´s just you bro. What are you doing?" your sister says.
She now is sitting at the far corner of the coach making it impossible for you to touch her.
You keep watching tv with your sister until the evening.
