Crisis! A Sister on Each Arm

From that day on his girlfriend made sure to never leave him alone with the little sister...

Where are you GodsHandOnEarth now is your time to shine!!!

We need the sequel with the loli ASAP! Also a threesome!

When your tsundere loses her cool, and her tsun together with it.

So, uhm...."All according to plan", I guess?

Little sister is dangerous!!

What is it with the sisters and their creative ways of taking their socks off?

We need a sequel with the little sister.

Crisis...? Doesn't sound like a crisis at all to me! More like Paradise...Or Hentai.
Still, what a wingman her little sister is! Revealing right in front of him that her elder sister masturbates to him, and then leaving them alone to...sort out their feelings.
"My Invaders and I lived happily ever after"! Nice. I will admit I was kind of hoping the younger sister would also join in, but...Well, that ending...! No need for him to get tired of your sister, just go for it! I'm sure he can handle you both...
Any chance of a sequel, perhaps? Make good on that title and have him actually get them both?

anyone else wished this would be a three part story, with the second issue being he gets the other sister, and the last one with all three together?

When your wingman is his own wingman at the same time.

Little Sister used 'Revelation' ... IT'S SUPER-EFFECTIVE!
