Okay, this story was starting to excite me until the mother came into the room, and then it got expodentially better. I wasn't expecting that, but the idea of the mother approving, of it being a secret part of her own family culture was quite a turn on. This needs more chapters! My mind immediately wonders about this approved activity actually bringing this man and wife closer together, and about family gatherings when his wife renews relations with her own Daddy, and maybe some extended family with cousins etc. If Daddy's teach daughters? Do Mother's teach sons? Does Charolette have brothers who fuck her too? Do they have wives who are in on the action? Family orgies seem like quite a turn on. Please write about a family reunion of Charlottes family.
