Turned into a slut

She lay me down on the bed and sat on me while she took her shirt off. She gave me a few playful slaps around the face and I gave some back which she really liked. We made out a little bit with her on top of me and then she took her trousers off. She mounted me again and pinned my arms to the bed and told me to fuck her. As I went to move she kept my arms pinned. She wanted me to fight for her. So there we were, I trying to playfully escape her grip and she holding me down harder with each new failed attempt. She began to tease me and said I mustn't want her that much after all. She started asking me why wasn't I fighting for her and began to hit me round the face a little harder than before. I didn't mind because as soon as she started telling me I was acting like a little bitch I knew exactly where this was going.

As nervous as I was (never been bottomed before), I didn't really have too long to think about it. She had my legs in the air spread apart and entered me pretty much dry as could be. It was a huge shock to me and I told her there was some lubricant near the bedside cabinet. I went to reach for it and she pinned me down really aggressively and slapped my face hard. 'Don't you dare reach for that you little bitch, tell me you're sorry'. So I did and she just went hell for leather after that. She was fucking me really hard and I was enjoying it but any time I tried to speak she would either put her hand in my mouth or fucking slap me. Even when I reached for my own cock she was having none of it. She kept saying 'Tell me what you are. Fucking say it' but every time I told her I was a little bitch (which was really turning me on) she would hit me or put her hand over my face. 'No tell me what you really are' so I just screamed at her 'I'm a fucking slut!' She smiled and pulled out of me and before I knew it her dick was in my mouth fucking me so hard I was struggling to breathe telling me I liked the taste of my own ass. She pulled out of my mouth and told me she was going to come on my face but I begged her to come in my ass so she turned me over on all fours and started spanking me hard and blew her load up me. It felt so good.
