Could I enslave my roomate ?

Hi man. My name is David and I'm 25. My English is not perfect, but I think you can understand me. Here the thing: I live with a slightly younger gay roomate. We got along very well, he's openly attracted to me but he knows I'm straight and he never oversteps boundaries. Nevertheless, I feel like he's very deferent to me, and he always compliment me a lot. He's very friendly with girls and he always praises me to them and encourages them to fall for me. And he loves hearing brag about my fucking them. I must admit it boosts my ego to have a gay buddy like that. Looking to your blog, I'm starting to think I could have him submit to me even more. I don't want anything sexual, but I'm interested in having a loyal servant boy. Do you think I could take steps further ? And how so ?
