The dirtiest thing in public i have ever done

It may or may not surprise you but my BF once bum fucked me in a shop doorway in Dean Street London W1, i was wearing a short red dress & high heels & no knickers at the time & he made me walk 5 streets to the tube station with his cum dripping out of my bum & running down my legs.

it was one of the sluttiest things i have ever done in public!

yes it was incredible at the time & we were both watching peoples faces to see who had any idea, the back of the red dress had a big wet patch too.
Best part was standing on the platform at midnight waiting for the train & i felt a big blob of cum slip out of my bum & could not stop it running down my legs. X
