Can you help me big brother

Your little brother came to you, worried that he might be gay. You told him its ok if he is. But he wanted Your help to find out.  You agreed to help if you could. Before you knew what was going on he was on his knees in front of you.  He put on some of you girlfriend's clothes.  He wanted you to feel comfortable.  He looked so hot. "So... just pull it out and let me... touch it... and if I don't like it, theres the answer right?"
