Glad It Happened Finally

I'm a bisexual female and my dearest friend she's straight as an arrow. We hang around together and do plenty of social stuff. I tried to get her to do some female to female sexual activity with me but she refused. She enjoys giving blow jobs to men. One day I decided to drop by her house and she introduced me to a gent she just met at a dance hall. He was a decent looking guy and I would screw and blow him too if given the chance.
She confessed to me that he enjoyed her blow jobs and he has a long lasting dick and tongue. She admitted to me that he liked the size of my boobs and saw the veins when I flaunted my cleavage. The three of us started hanging out together a lot. He learned from her that I was bi and tried to hit on her. He kept pressuring her for us to do a threesome so he could have fun with my big tits.
We went to the local flea market often and there was a seller I wanted to impress. I convinced my best friend to kiss me and feel a tit of mine as we walked by his selling booth. She agreed and told her boyfriend what was planned and he liked the idea of seeing us two kissing.
The three of us went to my best friend's house and opened a bottle of wine. I was flaunting my cleavage that day. " I enjoyed what you gals did at the flea market, do it again for me just for kicks. " her boyfriend said snickering. I guess my friend had a bit too much wine in her, she stuck her hand in my cleavage while kissing and tongued my mouth. She unbuttoned my blouse and told her boyfriend to feel and see the hangers I have. While her boyfriend was busy with my tits as she pulled out his dick and was giving him a blow job. I decided to join her sucking his dick and having her play with my breasts.
My friend told me her boyfriend wanted to see me nipple tit fuck her hairy c**t with my tits and I did as he watched and pulled on his dick. My dearest best friend became more dearest now that she's bisexual.
