I have always wanted to be tied up by my wife but she was never into it. She said if she ever did it, she would leave me there all night. One night she finally broke down and did it for me- blindfold,gag and all! It was totally erotic. She liked it, too. But she made good on her promise. While I was laying spread eagle on the bed, she shaved my ENTIRE body while she giggled and left me there all night while she went downstairs to read a book.
She came back in occasionally to give my balls a squeeze and a slap or two. She really enjoyed inflicting pain on me, which surprised me.
Then she slept in the other room. It was very uncomfortable, especially not knowing how long I would be there, but it was extremely exciting.. She untied me in the morning and asked how I liked it. I lied and told her I didn't. I didn't want her to think I did, or she probably wouldn't do it again.
I loved it, being so vulnerable to her every whim for such a long time. Everyone should try it at least once.
