Wouldn't it be fun to just sleep with Yaia, i.e. actually sleep and not to anything else (no rape), unti you she wakes up and does breakfast for you. Then you could maybe play house for a bit or maybe read for her until you take her to the Grandcypher kindergarten run by Grimnir and Suframare and go do you Skyfaring business. Then return home in the evening, play with her and Charlie Horse a bit more, eat dinner, help her brush her teeth, then put her to bed and read her a good night's story. Once you go to sleep she often would climb out of her bed and come sleep beside you (that's why you're sleeping together (no sex) at the beginning.
Wouldn't that be pretty fun?
