I fucked him like my life depended on it [FM]

My best friend has been in a long term relationship with her fiancé forever. We are open about things and discuss sex. She does not like giving head but I do and she knows that. One day out of the blue she asked me if I would suck her finances dick for his birthday. She said it wasn’t a threesome, she would only watch and I would only suck him off; he isn’t allowed to fuck me.

I arrived at their place and they wasted no time. We stopped mid hallway to the living room when she started undoing his pants and signaled me to get on my knees. She pushed my head onto his dick and started sucking him; he called me a good cock sucker. She told him, I was his birthday present. He told me to open my mouth and stick out my tongue… when I did he finished on my face.

Some weeks went by and after getting home from a party we all went to, she asked if I would join them in bed again. We stripped naked rather quickly and soon she had her finger in my pussy. He pulled out a leash and started putting it around my neck and explained how I was a much better pet than my best friend and sucked his dick like I mean it.
