No, it doesn't seem to be a common type of story. The term 'daddys little girl' is a familiar concept, but the addition of 'bj' makes it very unclear and not something that is typically seen in mainstream story - telling.
Well, if 'bj' stands for something like a place name (e.g. 'Blue Jay' or 'Beverly Junction'), then it might be a story about a daddy's little girl in that location. However, it's also possible that this is an abbreviation for a more complex concept or activity that we don't know about yet. Without further information, it's really hard to say exactly what the story is about.
ABDL (Adult Baby Diaper Lover) stories often involve themes of regression and caregiving in a non - sexual, consensual context. However, without specific examples at hand, it's difficult to tell particular 'daddys baby girl abdl stories'. One could be about a 'daddy' figure taking care of his 'baby girl' when she's feeling down, like making her favorite food and tucking her into bed with a warm blanket, in a very nurturing and protective way.
Sure. In one story, the 'daddy' notices that the 'baby girl' is feeling a bit lonely. So he arranges a special day just for her. He sets up a room full of her favorite toys, like stuffed animals and building blocks. He then spends the whole day playing with her, building towers with the blocks and having tea parties with the stuffed animals. By the end of the day, the 'baby girl' is all smiles, feeling loved and cared for.
Since the 'bj' in your title seems out of place and not clear in relation to the 'little sister swallows seed' part, I'll focus on the main part. It could be that the little sister swallowing the seed is a key event in a story about a family. Maybe it causes worry among her family members, and they have to figure out what to do, like whether to take her to a doctor or wait to see if it passes naturally.
There was a girl called Emma. Her dad was her hero. When Emma was learning to ride a bicycle, her dad spent hours with her in the driveway. He held the back of the bike at first, running along as she pedaled. When she finally rode on her own, he was beaming with pride. Emma knew she could always count on her daddy, and she was his little princess. Their bond was unbreakable.
This is an unacceptable and dangerous practice. The risks are numerous. It can cause infections as semen may carry various bacteria and viruses. It can also lead to digestive problems in the baby as their system is not equipped to handle such substances.
This is a very serious and wrong idea. Babies, whether boys or girls, have very delicate digestive systems. Their diet should be carefully selected. Foods for babies are strictly regulated to ensure their growth and development. Any abnormal or inappropriate substances like semen should never be given to them as it can lead to severe health problems and is also unethical.
