Submissive female handsfree orgasm in leggings, BDSM

Description: I’m naked in front of my master, i put on a leather collar and an anal toy as a plug, put on a thong and my sluttiest gym clothes (yoga pants and a revealing top). then i gag myself and cuff my hands through the collar. i struggle to make myself cum while dressed and restrained in any way i want but i am not allowed to use any vibrator. my master said if i can't make myself cum the next session might be all about spanking... so i try my best to make myself cum…
