VN I can't remember which game

[Myrroddin]

What I remember about the game:

• The MC was a married father of two or three girls.
• He has a sister who has two daughters.
• The MC and his sister have sex in the same room as the older daughter while she sleeps.
• The older niece is a troublemaker who pushes the MC's buttons, knowing he wants to sleep with her.
• The younger niece is into cosplay, and she and the MC go to a hotel and enter a costume party.

Do any of these ring bells?
