A twist in the tale

Not what I expected

As I came in it was all dark themed , like I saw in dungeons online , as I went I saw her all black dressed up even with knee high boots , I was already planning to submit to her but if that could happen , she said that it is our 3yrs congrats for that , let's together watch a movie , I fell from sky ,I was wondering that's it ?
As the movie progressed , I personally didn't like that movie , so as it was progressing I started watching porn on my phone , she suddenly saw it and caught my phone and threw it , she scream " what is it that you want?  " I replied without thinking " you as my mistress " and it began she , started to roam about brought a handcuff , kitchen spatula and other domestic stuff , and then she said " now just wait and watch you will never ever crave for bdsm as you no longer would need to ... Now call me mistress " she said while forcing me on my knees I said " ok " and smack I got slapped it was firm I was happy somewhat crying then she said " ok what ? " From that point I understood I was in wrong waters , I started to ask about her plan , but she ruthlessly started to beat me , sometimes main point sometimes all over body , I was burning like hell. When she stopped and said ," is that it , can we be normal bf gf " I was amazed , I thought she was enjoying it for a moment but I couldn't answer as I forced to sleep beside her bed on floor , which was stone cold ....n on the morning as it happens
