Well done Anna! I took the pictures down to save you further embarrassment. The bit in your story that makes me laugh is the part
“I don't know why, but I agreed”
What do you mean you don’t know why? We all know why – its because you're a dirty posh little gangbang slut!.
Hmmmm. I’m going to have to think of some way of making you tell the rest….
I know! How about a little pre gangbang picture? I’ve blacked out the eyes to protect the innocent.
I’ve always been interested in who was who that night and you’ve never told be what happened in round two. I’m all ears Anna – don’t be shy now. We all want to hear about it. If you do a good job I’ll take down the picture and the rest can be our little secret 
Image altered due to Anna’s compliance below.
