This story, (all three chapters) are at the same time deliciously erotic and emotionally tortuous. Can it go on? I do hope so! It is splendidly written with unexpected twists and decidedly naughty turns. There's not much in need of improvement here except an imminent 4th chapter! Brilliant story!!!
I think Cassie007 is the best consistent writer I have read. I love reading about sister sex.
