Toujou Tsukushihis with a master class of older girl x younger guy osananajimi vanilla where the guy grows up hot and the girl cant handle it lol.

Sweet lord the amount of osananajimi vanilla has been off the charts lately!!!! PRAISE BE!!!

-got the tsundere tag added.

...I need more primary fem lead perspectives in vanilla comics. Absolutely losing my mind over how hot this was, and how sweet the opening was before it went fully into x-rating.

Yuuri, go forth young man! She is your destiny!

Now this is what I would call a most flawless victory! Toujou-sensei delivers once again!

Another great older Osananajimi story!

And so the eternal eternal "Osananajimi" pairing passes away, to be replaced by another Sexy Onee-San x Younger Boyfriend couple.

"Perfectly Balanced, As All.Things Should Be."
