Alpha wants me to cum when serving him. Do I obey or convince him to lock my cock away?

The alpha I’m serving likes for me to cum when serving him. I know that I am a faggot and fags don’t deserve to cum but I do it because he tells me to. He likes how tight my ass is and loves how tight I get when I cum. It’s confusing cumming when I know that I don’t deserve to. Do I keep obeying him? Do I lock myself up? I’m confused because he’s a dominant alpha in every aspect but this. He’ll blindfold me and spank me till my ass is red and I’m crying because of the pain and he uses me hard, both holes. He’s aggressive and dominant and I love that he gets enjoyment and pleasure from my body. I’m just confused because I’m pretty sure I should stop being allowed to cum and that he should take my cock away from me but he says cumming when I’m told is serving him so it doesn’t matter. What should I do?
