Fun game. I have few ideas which i think would be interesting.
- at some point Clara could act a little disappointed that you chose to donate instead of finishing on her (maybe without actual effect on relationship)
- maybe she could sometimes ask by herself that you should finish inside
- it would be nice it there was an option to finsh in her mouth (without making her angry)
- she could sometimes tell where she wants you to finish (face,mouth,tits,ass,inside)
- if you go to sleep without visiting her she could ask for sex by herself
