What Would Your Missus Say?

Your girlfriend has sent you round to her friend Rose's house to pick up a pink top that she left there, Rose is unsure where it is so she starts looking under the bed and you quickly notice the very sexy gold panties she is wearing under her tartan skirt. You know you shouldn't be looking at your girlfriend's best friend's ass but you can't help yourself, you can feel your cock growing in your trousers and Rose quickly realizes what you are up to.
