Have you ever been tied up and fucked by anyone?
Yes, I have. On several occasions.

Was it with a group or just one person?
Just one each time. The first time was by my (now) ex-wife. She tied me down, blindfolded me, gagged me, and left me to stew for about 30 min before she came in and rode me hard and wild. I found out later that she'd set up the video cam and had recorded the entire scene.
The second time, I chained myself up spread eagle, blindfolded, and gagged at the direction of my Lady while She was at work. When She came home a couple hours later, She fucked me until She came, then left me frustrated and chained for another hour before letting me loose.

Were you blindfolded?
Yes.
