Long-term bondage (raincoat, sauna pants, wellies and gas mask)

I love being immobilized in perfect bondage for a long time. it's a beautiful and exciting feeling when i'm helpless for a long time and there's nothing i can do about it. in this video, i combined long-term bondage with something useful for me, namely the need to lose weight. that's why i'm dressed in plastic and pvc clothes that will make me sweat. i'm wearing a transparent raincoat, sauna pants and rubber boots. i have a wetsuit hood on my head and a gas mask over it. dressed like this, i am tied to a sloping wooden plank. even though i am already quite firmly immobilized by ropes, leather straps and handcuffs, my husband comes to immobilize me even more. to do this, he will use stretch plastic foil, which he wraps around my body and legs in several places. i'm totally helpless, with no way to move. now i am doomed to just lie motionless on a plank and wait. i enjoyed being in bondage for a few tens of minutes when my husband comes, who is obviously excited by the sight of his bound wife. husband stroking my body, hands and starting to masturbate. he also fucks my hands. i can't help him much because i have handcuffs and thumb cuffs, but i try to touch his penis and balls. my husband alternately masturbates and fucks my hands in handcuffs until his orgasm comes. his cum falls on my plastic raincoat. then i'm left alone again. i don't know how long i'll stay immobilized. you can watch a three-quarter-hour cutting recording of my long-term bondage.
