Tomorrow's plans xx

This week has been a strange week, but in a very good and surprising way.
My girlfriend canround on Monday and we had our usual sex session, than afterwards we were laid in bed talking when she asked me if she could fuck me with a strap on. I was a shocked, but of course I agreed (without trying to sound too enthusiastic lol).
So I picked up my phone and ordered one. It arrived the next day, sonny girlfriend popped round on her way home from work to fuck my ass.
While she was fucking me she told me to call her mistress, which I did and it made her horny as hell, and she kept telling me that I was her slut, hearing her say that almost made me cum straight away.
Afterwards she told me that she wanted to dress like a dominatrix and fuck my ass while I wear stockings and high heels.
I agreed and told her that I would order them, but what she doesn't know is that I already own some heels and stockings and that I wear them whenever I get some time alone.
Hopefully this weekend she will tell me that she wants me fully dressed as a woman while she fucks me.
