Tomodachi no Galge Mitai na Gikazoku o Musabori Netotte Haramaseta

Our hero's friend has a pretty hot stepmom... and a similarly sexy stepsister...
Being around them is just like living in one of those hentai games!
But there's not really much he can do about all those pants feelings he's having.

Not until the government gives him a special pass... To counter the falling birth rate,
men are being issued "mating passes", and he got one! License to fuck in hand,
he has no trouble taking his friend's stepmom thanks to his youthful energy.

The stepsister follows soon after. and now he's got the two women of his dreams to himself!
Once they're his complete masochist pets, the real mating can begin...
