I am bi-sexual and I will relate a fulfilling experience along those lines.
I had a date with a younger couple. She was built like the proverbial brick shit house and he was good looking. He made the initial advances and feeling each other up, I found he had a large cock and wanted to fuck me. I fell in love with that cock and couldn't wait for him to shove it up my ass hole. His wife watched for a while and then came around and laid down in front of me with her legs spread. Her pussy was wet before I put my tongue in it. Between her pussy and her husband's cock in me, I got so excited I came. I loved eating her pussy until she came. I licked pussy juice out of my moustache and beard for several days.
