Raising and lowering myself, I took him in a little at a time until finally I pushed down all the way. I had never taken a cock that big before and I ...as so packed full on dick that I knew I was gonna cum again very soon. I moved up and down, fucking myself on his amazing cock as he went back to work sucking my nipples, moving back and forth from one to the other. I was on fire from the sensation of fucking his big dick and I was ready to cum again but I wanted him to cum with me. I began. Finally, if I am going to teach you about sex, I will teach you in my way, and that will require that you speak to me, and respond to me with respect. Now, try it properly.”Still goggling, apparently overwhelmed, she failed to make the connection. “Huh?”I turned to Linda. “Are you my slave?”Linda had been paying attention. “Yes, Master.”“Must I show Britney how I teach my slaves?”“If you wish, Master.”“Linda, if you can bring Britney up to speed, this afternoon will be considerably more. Quikly my cock became hard and uncontrollable throbbing took place inside my pants. I unlocked my phone and placed my hands holding it over my raging boner to hide it. I started reading posts on facebbok and at the same time chating with her, untill we made a stop. That was a regular thing to stop for 20 to 30 minutes. After we stoped, the next 5 minutes were in complete silence. Then she says" Its ok. Its completely natural to feel horny sitting next to me when you spend every day hanging out. I eased forward as Lucy wrapped her legs around me and used her heels to encourage me further. A quick push and I was in, all the way, meshed.Holding her I rolled back onto my back taking her off the settee. Lucy now in her favourite position, sat on me, controlling and able to dangle her lovely titties in my face.Bliss!Rolling in and out and squeezing him at the same time produced marvellous sensations for both of us.Even though I had not long produced a very wet cum I did so again. By now.
