Say What You're Going To Do
Want to tie your partner up and have your way with them? Tell them that you're going to do it. This will build the anticipation. Also, it'll give them an opportunity to tell you whether or not they actually want you to do that. Again, the more communication, the better.
No one likes an empty promise! Go ahead and tie them up, as long as you have gotten consent, of course.
Don't stop just because you've, well, stopped. Telling your partner what you just did will prolong the experience, and could lead into something else. So, saying "I just tied you up and had my way with you" could prompt your partner to then respond with what they would like to take a turn doing. It's the gift that keeps on giving.
