Partner treats me like a sex lap dog

MY girl likes to play power games.

- 

Recently she held an intimate party. She made me have sex with one of her friends in front of eight others.

The friend was fired up and horny after a painful break up.

My girl stormed that I would "spoil the party" if I didn't step up and service her. I didn't feel like putting on a public display of lust but felt obliged to.

I knew that I'd never hear the end of it if I refused. Later she rewarded me with a pat on the head - I felt like a lap dog.

In the 18 months we've been together I've come to realise that she is not someone I can reason with. It's her way or the highway.

Her exec job is very stressful.

She storms in each night on a huge high. She demands food, drink and unlimited lust.
