I was really horny and wanted to get dominated so I called my bf. I got him to tie me up and he put two vibes in me. One in my ass and the other in my pussy. I had a ring gag on so my moans were pretty audible. He then set the vibes on a pretty high speed and proceeded to face fuck me. (this all happened at his place) He then said he needed to use the restroom and he'll be back in a few minutes. Before I could ask him to piss on me he was already gone. A few minutes go bye and I'm starting to feel pretty lonely and I look up to see the door opening again. I thought it was my bf but instead, his mother walked in. NGL this kinda turned me on but then she quickly left screaming "sorry, I didn't know (bf's name) was into this". This was kinda funny because this is mostly my kink that's thrown on him. When my bf got back I asked him about it and he laughed saying that he walked in on his parents doing this and walked out saying the same thing.
