What are you doing step-brother? Why are you in my room? I've barely got any clothes on! Wait, What is that in your pants? Ew, Do you have a boner? You are such a little freak! I'm sure you'd love to rub one out right now...perv.
You know what, I have an idea. Why don't we play a little game? When I say 'green' you can start stroking and when I say 'red' you have to stop stroking and stare while I continue to tease you.
No cumming until I tell you, got it? Is this a dream come true for you?
