Find your brother

You start thinking of your older brother Nathan and how hot he is. Your friends have been telling you about how big his cock is and how good it feels and imagining it filling you up makes you drip even more. You quietly get out of bed and walk out into the hallway, and you notice that the bathroom door is slightly open and you hear moaning coming from inside.

You curiously walk in, and you see Nathan on the toilet masturbating, stroking his hard cock and moaning softly. He doesn't notice you yet since he's not paying attention to anything else. He's 21 and completely naked right now, and you smile as you watch him, preparing to give him a lovely surprise.
