I can't find my all time favourite story

I used to come on here and read a 3 part series about a step sister who helped her step brother become flexible enough to self suck his cock. In the process she turned him into a sissy. I read it lots but now cant find it. I thought I used to search for Self sucking sissy. But I cant find it now. Can you help?

Probably the author deleted their account. Their stories die with them.

Do you recall the authors name?

Sadly don't remember the authors name. If the author did delete thier account that is sad. They were great stories.
