Night Before My Wedding

Leading up to my wedding 3 months ago i made a confession to my best friend. My confession was that i have had strong feelings towards my cousin,I knew she would keep it secret.that night before i was getting married it was meant to be just us but she had a surprise for me.around 8 o'clock my surprise turned up,my 28 year old cousin. I said to my friend how's this a surprise it's my cousin ? she said she had told my cousin my confession,as i was upset and letting her know she betrayed me my cousin started groping me hey one last night of fun he said,I didn't know how great a night it would turn out to be.it wasn't just me my friend joined us.the sex was amazing on off for a while and drinking plenty before we all passed out.wake up in the morning to find my friend and cousin fucking next to me and i joined in,that last night of fun turned into an affair.
