Playing with a slave girl

Today I became the helping hand of Mistress Fiona. She owns multiple slaves, today we've been playing with Slave girl Noortje. We've been using the magic wand vibrator on her, but she started getting a bit too noisy, so Miss Fiona decided to gag her (which was actually a great decision). Then we tied her to the door and took turns in spanking her! She had an orgasm and we kept spanking and vibrating her! Hehe
