The build-up for me is important- I love spending hours mentally debating about what I may do to sh. I enjoy making him feel vulnerable, so I focus on that. Blindfolding is great because not only does the lack of sight enhance his other senses, but it also leaves him completely unaware of what I may be about to do.
When I have decided on what I have planned for him, I begin teasing him. I whisper to him that his ass is mine later (during dinner), or that I am going to punish him and leave him begging for me (while sitting in the car). I will casually grope his cock, telling him that it is mine. By the time I am ready for him, it is all he can do to contain himself!
