Starlight Nursery: An ABDL sci-fi regression story (Paperback) (ISBN-13: 9798255282333)

It's the 25th century, and Calren Voss is the chief scientist and sole inhabitant of a distant space station - Eunoia Station.

Calren likes the privacy and quietness of the station, and his psychological tests and performance showed he was perfect for the job. But the tests missed something. Calren secretly wanted to be someone else. He wanted to be a baby, not an adult. He hid it from everyone, including himself, until the loneliness came calling for more...

Out in space, no one can hear you cry for a bottle or a nappy change. Unless, of course, you have an advanced AI robot called MIRA.

And then you hear a distress call, and you are the only one within range, and so your solo life will soon come to an end...
