That should cover a few of the common BDSM desires. Atleast most of mine haha.
Tease and deny him with your pussy. He must crave it, but never have it. Use it to get him excited first, then he will be easy to have do other stuff.
Talk dirty to him. Tell him how nasty he is. Tell him how pathetic he is. Laugh at his cock. Tell him it's worthless. All the fucked up shit you think about him in your head. Just tell him, because he wants to be told just how fucked up he is.
CBT - tie up his junk and yank on it for fun. You will see quickly what he can tolerate. You can slap it and hit it and pinch it etc. You will see what his level is pretty quick.
Golden showers - Give him a full stream, don't try and slow it down or stop / start for him. Just sit on his face and piss like you would any other normal toilet. It's his job to keep up with your flow and drink it all down. Tell him that is what is expected. Reward him if he does a good job by letting him remain in the presence of you pussy just a little longer.
Rimming. He wants it. He also wants it a bit dirty. He doesn't want to taste any hint of soap on your arse, if anything, he wants to taste a hint of shit.
Pegging - If he is up for that, then ease in initially but you can work up once he has settled a bit. Tell him your just working his prostate so he has a big load to eat.
CEI. If he cums, he eats it. You don't want that mess around. If he makes a mess, he cleans it up. Simple. When he cums in his hand, grab him by the wrist and bring it to his face. Make him slurp it up. He will be disgusted, but if you can push through that and convince him enough to do it, he will love you for it. As quick as you can aswell, immediately after he has cum. You don't want him to get any post-nut clarity before eating it.
Findom - he wants to feel like he is useful to you. He wants to feel like he is supporting you. Don't rip him off, but make him know that's what his job is. Tell when that you expect a gift when you see him again, (next week). Make him bring you a nice bottle of wine, or a fancy box of chocolates or whatever.
Foot worship. Your feet are physically the lowest part of your body. So natuarlly he should be below that. Make him kiss your feet. Rub lotion in and massage them for a while. Then step on his cock. Walk on him. Stand on his chest.
Main thing is you must never show him any weakness or indecision on your part. He wants you to be the boss. He doesn't want to have to be in charge of any decision making. That is your job. You can ask him about likes/limits prior to the session. But once it begins, he doesn't decide or refuse anything.
He wants to feel used. He wants to feel like an object. He wants to feel like a usefull thing for you to have. He wants to feel shame about his desires. He wants to feel disgust and embarrassed by what you do to him. He wants to see you get some enjoyment from his servitude / suffering / use. So when he does do well, show him that you are satisfied/pleased. He wants to please you, he wants to see that reaction in you.
During the session, you must never ask him whether he likes something or not. Or wants to do something or not. You only TELL him what he does or does not do, what he likes or dislikes. And don't compromise, if he initially objects to something, he is just testing your resolve. He is testing to see if your gonna be hard enough to bend his will. If he feels like your just doing what he wants, then it won't feel right. Even though you are doing EXACTLY what he wants.
