I started asking her how he was at sex. Suddenly, mistress Debbie texted me: “Slave!! How about you serve both me and my boyfriend? That way I get t... keep you as my dog and you can serve your master in whatever way he chooses”. Literally, my jaw dropped. I was confused, I could never say no to my sweet Debbie mistress and she knew it. I had a thousand questions in my mind. I asked her what ‘serving him’ meant? She said, “Silly, it means my bf may ask you a blowjob or ask you to be taken from. His mom came in a few minute and said goodnight and as she closed the door she said o "have fun". We looked at each other and giggled, we intended to. As soon as the door closed we shed our pajamas and I started on his asshole first useing the stir stick then spending some time licking it, then it was my turn and spent a long time licking mine then we were ready to start playing with our cocks. Again I started by useing the fur to rub his now stiff cock until he felt the tension and told me to. "I like it," Yvonne replied, surprised. "It's different, but it works ... Are you getting... ?" This is going to work," I assured her. "You're doing well." I shifted my attention to the visuals and enjoyed the pendulous swing of Yvonne's breasts as she impaled herself on my erection, again and again. "You can masturbate," I informed her.She shook her head. "Need both hands..."I was starting to charge up -- I could feel it. All things being equal, I would discharge in Yvonne's colon in less than. I was acting as if I forgot where I kept my towel…and searching for it, still exposing my naked back to her.P: What are you searching for?Me: My towel, I have forgot where I kept it.P: It is ok there is nothing new to see again, you give me the Pulley I need to finish the work and go fast.Me: Ok.I went inside and brought the pulley along with me and handed it over to her. While taking the pulley from me she tried to touch my penis but I moved away swiftly.P: I can’t fix it on my own please come.
