For me, SB began when I was quite young in junior school, and now I can't remember it not being a major part of my life.
SB brings a lot to my table, so I'll break it down.
The feelings & emotions that get stirred up when I'm tied up & gagged are strong.
I like feeling helpless, or as much as one can be though you know you can get free when you want.
I always like to enter another fantasy world where I've been abducted & kept prisoner & used as a sex slave. Whilst tied to my double bed spread eagle, I consume myself in that scenario & I find it very relaxing to escape, though not physically of course.
I always place a mirror at the base of my bed so I can see myself in that vulnerable position, and I also have a small mirror attached to the centre headboard post so I can see my head & face &
I need to have that visual endorsement of the way I'm tied & gagged.
Whenever I'm troubled or stressed out, a long SB session always ensues & by long I mean many hours. It takes around 20 minutes for me to get dressed, which is knickers, bra, stockings & suspenders, long sleeve stretchy bodycon & sometimes knee length boots.
A gag & panty mask is mandatory & I can't reach that full helplessness feeling if I'm still able to talk, so one or two pairs of my knickers are rolled up & go inside my mouth.
Then I get tied to my bed at the ankles, above & below each knee, waist, neck & the rear of the head harness is chained to the headboard centre post, wrists & above the elbows.
A 9 point anchor system keeps movement to a bare minimum.
A stocking hood goes over my head & keeps my hair from getting ruined & tangled.
I use trimmed down rubber inner tubes for OTM wrap gags & also under my chin & over head to keep my mouth shut. Talking is absolutely impossible that way & the good thing about rubber is it doesn't matter if it gets wet, it's grippy, stretchable, re-usable & free from your local cycle shop recycle bin.
Ultimately, apart from all those lovely feelings it always makes me cum numerous times, even without a butt plug, dildo & clit buzzer, though it's rare those things aren't in me.
Though my self orgasms aren't reliant on those, I can concentrate & struggle against the rope, straps & chains & try to speak that brings me to that point.
So overall, being severely restricted, gagged & hooded, plugged, dildo'd & held in an extremely vulnerable position whereby my captors can fuck n lick me whenever they want & use me as a sex slave to earn money from me & there's nothing I can do to prevent it, gives me a feeling like nothing else.
Everyone has their own reasons for SB, that's mine, hope you enjoyed.
