He starts sucking
From Create Your Own Story
"You want more? Cause if you do you'll need to work for it".
"What do you mean"?
"More comes out if you suck it".
Though he is a little taken back by your request, he stares at your cock trying to decide what to do. You realize that your brother has a tiny boner tenting his pants and decide to try to coax him just a little more.
"I promise you'll like it".
This is just what he wanted to hear as he had been unsure if he wanted to do this or not. So with him fully trusting you he gets to work on your dick. At first he simply wants to taste you and he takes a few experimental licks up and down your cock. Not thag you are complaining as you soon have to try to stifle your moans when he licks your cockhead. Soon he wraps his lips around the tip of your cock and slowly starts to inch forward, sucking intensely the entire way. The slow pace drives you crazy and you grab his head while thrusting your cock forward as hard as you can. He chokes and gags as you take his throat without a care for his safety. He punches your thighs and screams around your cock, but that just drives you more wild in your brutal fucking. You can feel you orgasm coming and have to make a decision quickly.
