Bad babysitter

I was babysitting at an neighbors house. When I finally put those little devils to bed, I called my boyfriend to come over. At first, we kept it more or less decent, in case one of the children came down, but soon we were making out on the couch. Since I felt still uneasy about the kids waking up and seeing us, we went to the master bedroom. And that's exactly what it was! In there we discovered the dark side of my employers, this was a full scale BDSM dungeon! On one side a wall fully covered with whips, paddles, hand cuffs and such... A drawer full of dildos, butt plugs and vibrators... We felt like kids in a candy shop! We ended up on the bed, my boyfriend tying me to it with the hand cuffs and ankle clamps, and filling my butt with the smallest plug available. Then he fucked me, hard, doggy style, the plug giving it a new sensation for us both. Later, we quickly cleaned the used plug, and put it back in the drawer. They never suspected a thing... Let me tell you this, this is my favorite place to babysit.
