3 orgasms while I was tied up and had my ass spanked

He did something completely new to me, or rather my ass, which I always stopped immediately when a guy started doing it. In the past, when a man managed to give me a slap on my bottom, I always immediately showed him that I didn’t want that. Out of sheer lust, I just let it happen today and when it suddenly became more and more beautiful, completely unexpectedly, I even asked for more of it. I even really forcefully encouraged my guy to keep pounding my ass while I orgasmed. I was so horny that I was actually drooling at the beginning and at the end I was in tears because of this incredibly beautiful and new feeling. Unbelievably, I even had three orgasms in a row as my ass cheeks became redder and my eyes became moister. OMG, am I developing into a submissive slave who can get even hotter climaxes from painful punishments?
