I focused hard on Sir's cock as I felt it hardening in my mouth. The new Friday night routine wasn't so new anymore, and it had certainly added a sadistic touch to our relationship. I'd go to any length, even the most humiliating, to receive any praise from Sir; all I wanted was to please him the way Blair could. I'd get home from work and before I even had the chance to get into my collar, it was my immediate task to get Sir hard for her. He wanted to be ready to enjoy every limited minute he had with her superior cunt, ass, and mouth. Knowing that I didn't even get to bring him to that pleasurable climax really hurt. I know he received pleasure from my emotional suffering as I doubted my value to him, and so I encouraged him to continue with her despite my unending need to serve and be of use to him.
Sir grabbed the back of my head and shoved himself balls deep into my throat. I struggled to not gag. Gagging never went unpunished even though it made him harder. I felt my eyes tearing up as I pleaded for air with my eyes, grabbing onto him for dear life, just hoping he'd show some mercy. He pulled back, waited about three seconds, then went right back in. Repeating this process was usually the way he finally became his hardest. It was as if abusing me was the source of his arousal more so than the physical sensations. On the sixth thrust into my poor poor throat, I failed to hold back the gag and I knew he was done with me for now.
"Go kneel at the door and wait. I'll be upstairs." He sounded like he was so ready to make me hurt. He only used that tone when he had sadistic plans. My pussy twitched.
"Yes Sir, of course." Miss would arrive shortly, and I would greet her and show her upstairs to Sir's new playroom. I always joked about wanting the house with a white picket fence and a dungeon in the basement. Well, we don't have a picket fence yet, but I wasn't too set on that part of the dream.
