Good son: try to talk to her

From Create Your Own Story

You say "hi" to your sis. She startles since she didn´t realise you before. She just says hi back and goes back to watching her show. I doesn´t seem like she is interested in talking right now.

good son: ask her if you can bring her something to drink

good son: just watch tv and remain silent

good son: trace your fingers along her buttcheeks

good son: start to slowly rub her pussy with one finger
