I'm talking with you, my step-son telling him I know he wants to fuck me. I build this up and tease a little. I say we should fuck and take off my clothes. Then your older step-brother comes in, naked, straight from the shower, looking for a towel. I see how big his dick is and I am quite turned on. He leaves and I let you know that I would never fuck you with a dick that small. I leave and go to my room.
You hear moaning and peak inside my bedroom door to see me fucking your older step-brother doggy style then riding him.
