The fifth humiliating scenario is one of my Mistress’ favorites. She calls it “The fucking chair”. This serves multiple purposes. It's entertainment for Mistress, it's ass training and it's part of my exercise and fitness regimen because it can utilize many other muscle areas depending on the positioning and is also a cardio workout.
While my Mistress loves to harness up a big strap-on dildo and fuck me in all kinds of positions, she doesn’t always have the energy to do her part. For this reason she had me build a chair that can have dildos attached in multiple locations to accommodate many similar positions. The chair also has eyelets to restrain my arms and ankles to keep me in different positions although she does not always require that.
Whenever she wants to relax but feels her slut needs a good fucking she will order me to bring the chair to the room she is in. She will choose the dildo to use, the positions she wants, how long in each position (or sometimes just how many plunges into my anal cavity to which I must count out loud), how fast or intense and if I am to be restrained into position.
She will then sit, relax and either be entertained or just ignore me while I fuck myself raw to her pleasing. Sometimes she sends short videos to friends or makes me carry out this activity when a friend is over. In times of punishment she has covered the dildo in a hot sauce to make it incredibly painful.
One time she put me in a very tiring position and would not allow me to stop until I’d begged and offered to do a number of other things willingly which I later had to pay dearly for in carrying out those promises. In fact there is often some kind of devious twist to using the chair for which I’m always getting screwed well beyond the fucking itself.
One version she absolutely loves is to blindfold or hood me and shove a penis gag in my mouth. She'll then position the chair where she wants it which I will not be able to see how that is, move me into position facing the back of the chair, cuff my ankles to the back legs and then cuff my wrists to the chair back with just enough give to be able to use it for a little stability. THEN she'll choose and attach the dildo I will be fucking, will lube it at the tip and then slowly lower me down until she can line it up with my asshole. At that point, she will order me to slowly lower myself into a full seated position so it is fully inside my ass followed by my orders on how to fuck it and for how long. She will not let me out of it until I have satisfied her orders and since I cannot speak, I am helpless to do anything but comply. One time she purchased and used one that was so long that it took me maybe 15-20 minutes before I was in the sitting position. I thought it was going to rip into my intestines it was so long. It felt like it was in my stomach. It was an extra unpleasant self fucking. Later that night she showed it to me and it must have been 15 inches. Although it may have been shorter, it had felt at least twice that! It was black and veiny and was so long that it couldn't even stay straight on its own.
