When I first became Mac's, I had not had sex with anyone for almost 9 months. My last partner and I had only had sex 4-5 times over 3 months. The one before that was a Dom who required absolute obedience and complete silence during sex. In fact, the most he wanted me to verbalise was to announce my orgasm so that he would know I had come.

As sterile as that sounds, I have to admit that at first it was hot. As time went on, it got a little bit stifled, but at first, it was really hot.

So when I became Mac's, I was very unsure how to act towards Him. He made it pretty easy though, He just took what He wanted when He wanted and all I had to do was enjoy it and comply. I fell into the role of making Mac want me. Because we were living apart, that was simple. I could put my dirtiest thoughts into email and if it made Him horny, He would come over and take me how He wanted me.

Although we never talked much about it, there were a couple of occasions where Mac was a little confused by the really sluttish tone of my letters and the demure and compliant girl He was fucking. At times He found it amusing, at times He found it sweet. Sometimes it frustrated Him. At times He wanted to fuck the woman that had those dirty thoughts and instead got a silent but willing partner.

I remember one day when I had written Him something especially dirty and He had come around and He had asked me to say the things I had written and I hadn't been able too. Not even a little bit. We ended up making love and Him leaving with a frown on His face. I was destroyed. I didn't know why I was so shy with Him. I didn't know why I suddenly became like a frightened little virgin when He walked in my door. I wrote to Him and told Him that I didn't understand why I was like it, I loved Him, I trusted Him, but I was so scared of saying the things I thought and felt. I just couldn't relax. I explained to Him that I wanted to do it. I wanted to be His dirty little slut and I would keep trying until I worked it out. He called me and told me it was ok. It had worried Him that perhaps He was pushing too hard and that He needed to back off, but He understood that it was something I could have trouble with and He was really pleased that it was something that I wanted to change. He told me not to worry about it, it would happen when it did.

He was right. It did.

Truthfully sometimes I still feel uncomfortable with the thought of being so open with sexual thoughts. I am so much better at typing them out for Him here than I am at saying them aloud, during the acts themselves. I am a lot better at it than I used to be, a lot more open and I am so much more likely to say things to Him such as 'I smell like Your semen' and 'Can we fuck?' I think more and more I surprise Mac with the things I say and do. I think it sometimes shocks Him into arousal to suddenly realise His girl is turned on enough to suddenly announce it to Him. I think because I present such a contrast of good girl and slut, it keeps Mac guessing just which one is lying beside Him at night. He knows though, that at anytime He can entice me into sluttishness and I think He enjoys that too.

Yesterday, while Mac was home, I put on some porn. It wasn't particularly good porn just some tape we had for a while and hadn't gotten around to watching. Mac and I tend to prefer to be having sex instead of watching it, but I was mucking around with the television and remembered it was there. I put it on. Mac heard the music and I guess the sounds of the people involved. There was no story line, it was just short scenes of different acts so there was no lead up, they just got straight into it.

'What are you doing?' came the call from upstairs.
'Watching porn,' I called back like it was the most natural thing in the world to be doing at lunchtime.

He came down in time to see a pretty girl licking and nuzzling at a huge cock.

'Oh, nice blowjob,' He said matter of factually and sat on the couch beside me. I snuggled up beside Him. He put His arm around me. My fingers ran over the groin of His pants. He shifted down in the seat to give me better access. I got the giggles.

Really I did. I found the whole idea of making out while watching porn at lunchtime extremely funny, especially since Mac and I are not huge fans of porn. Mac always insists He could do a much better job of directing a film. He would cut out all the head tossing and lip licking and just make them do it. He also assures me that all the come shots are done with warm yoghurt. It has become a bit of a running joke between us. Mac started laughing at me laughing but He kept better control than I did and recovered quicker. I was still giggling when He started to talk about the couple on the screen.

She was holding herself open, one hand on top of her pussy pulling up, the other at the side. Mac mentioned that He loved the way she was presenting herself to him. The guy was kneeling on the couch about to put his cock inside her. Mac told me that when the guy entered her she should move her hands and caress his balls and slide her finger into his ass to make him come. She didn't.

'You would've,' He said.

I had stopped giggling and I knelt on the couch and took Mac's cock from His pants. I positioned myself so that I could still see the television around His cock and He reached under my belly and slid His fingers into my pussy.

'Good girl,' He said.

I nuzzled and licked and kissed His cock and He caressed my clitoris while the couple on the screen fucked then changed positions and fucked again. Mac told me how much it turns Him on when I spread myself open to be entered and how much it turns Him on to see me enjoy myself like that. Mac and I were both close to orgasm when the man on the screen withdrew his cock and moved to stand beside her face. The girl opened her mouth and stuck out her tongue ready to take his come. He grunted and his cock spurted over her mouth and over her face and I came. She started to suck the head of his cock into her mouth and Mac came too. I was still in orgasm and Mac's semen was still spurting from His cock over my face and lips when Mac suddenly said 'They use warm yoghurt, you know.'

I almost choked then collapsed against the couch laughing. Mac started laughing too and both of us were still suffering spasms of orgasm. I thought I was going to wet myself. The video moved on to another scene but we had both lost interest in it by then. I turned over so that I was lying on my back with my head on His lap and we talked and laughed with each other for a little while before He had to get back to work. I got up to take a shower because I had somehow managed to get semen in my hair. We walked up the stairs and stopped at the bathroom door. He kissed me.

'That was fun.' I said.
'Uh-huh,' He smiled. 'You never stopped laughing.'

I blushed and He kissed me again.

'I didn't mind.' He said. 'I love it when you are like that.' Then He walked down the hall to His study.

I like that sex isn't a serious, never smile, intense thing between us.

At least, not all the time.
