A brutal reverse prayer tie, and then given a buzzing while I try to stay standing

Description: So an interesting one here. i had my arms tied up high behind my back, in a tight reverse prayer position. so when your arms are like this, it feels super vulnerable, because you have no way at all of reaching down and trying to stop someone from having a bit of fun with you. i was then gagged, and then had to stay standing while the buzz came out. i thought this challenge would be pretty easy, i mean, how hard can it be to just stay standing while being vibed? as it turns out, it's really hard!!! i start twisting and turning, trying to get away from the vibrator, but at the same time i just want to get off on it. in the end i just fold right over as the waves of orgasm spread over me.
