like i said, if it's genetically safe and if you not married. its not illegal.
Besides, mistresses for married men seem to be grudgingly accepted in Japan anyway.
Plenty of women have more then one partners even when they are married or not.
Only this time both girls are aware of each other and are fine with the sexual advance of the other.
Really, its makings more trouble talking about marrying just one. It's not like humans are incapable of loving more then one person equally.
