The woman I've been seeing for a while I have moved in with, I always have to be dressed when home and at weekends and my girlfriend often humiliates me and has become an expert in edging me with her strap on and little did I know she had been planning to meet a guy, that afternoon she chose my clothes, a nude short fit and flare dress with lace sleeves, black bra and suspender belt, nude stockings and patent nude stilettos, she then locked my little boy clit in chastity, no panties, she wore a sexy halterneck top, no bra, black suspender belt, black stockings and black patent stilettos with a sexy long pleated satin skirt, she bent me over and fucked me until I was close to a sissygasm then stopped and told me we was going out for a drive, I was so turned on I could hardly drive, we went to the carpark of a quite pub a few miles away and parked at the back where it was quite, we got out and went to the picnic bench we parked near, she bent me over it and continued to fuck me all the while verbally humiliating me, she knows that drives me wild, next thing I knew there was a guy stood in front of me with his cock out saying "you must be Lucy" to which my girlfriend replied "Yes, this is the dirty little slut", with that he pushed his cock into my mouth and began fucking it, his cock got hard, big and hard quickly, he had me gagging on it with my girlfriend encouraging him, after a few minutes she told him to fuck me and lay down on the bench for me to eat her out and worship her ass as he pushed his cock deep into me, this along with the verbal humiliation went on for about 10 of 15min until he withdrew and cum all over her pussy and my mouth for me to clean up, I couldn't hold it anymore and had the most amazing sissygasm, they arranged to meet again soon without me and he went on his way, we got back in the car and left........tbc.
