"I'm going to become Oniichan's waifu!"

Upon our parents being posted overseas for work,
me and Mai sister end up living together alone.
She just loves me and is all excited over our newly wed couple like lifestyle.

Cooking, cleaning, bathroom time and sleeping all together!
But, a man can only resist his sexual desires for so long...

"If you are going to be Mai Waifu, you'll need to service me 'here' too..."

Teach your little sister about how to sustain a happy married life!
