I tell you to take out your cock and stroke for me.
I know you love my armpits, so I'm going to show them to you while you stroke for me.
I talk all about them, how deep they are, how they feel, etc. I refer to you as good boy throughout and continue to encourage you.
I start with showing you close ups, but then move to a fuller body view where I touch my body and tease you. I encourage you to cum all over me and my armpits
