Need help teasing my boyfriend and driving him crazy

My boyfriend has mastered the art of teasing. He really knows how to get me going and I love it! I have a much more active sex drive than him so I’m typically always in the mood. Because of busy schedules, we won’t be able to get together any time soon and he’s convinced I’ll be the most horny next time we see each other. I’ve been trying to turn the tables on him recently and tease the hell out of him. I sent him some nsfw pics yesterday and was texting him telling him all the dirty things I want to do to him. The teasing worked there but I used up all my dirty talk! This morning I sent him two pics, one in which I was fingering myself and I’m sure that will set him off too.

Any more suggestions on how to make sure he can’t see me without getting hard? I want to drive him extremely crazy and let him know I can play his teasing game.
