Outframe [English], by Shiden Hiro

Many thanks to Masahito_Tenkouji, a kind commenter on Hentairules, for mentioning there was a “same universe” story related to Inframe, by Shiden Hiro

In the previous story, we focused on two highschoolers becoming lovers at last, thanks to the encouraging pushes of their friends. In the new story, we follow the pushers, the couple’s best male and female friends, who were already having sex long before the late lovebirds finally did the thing ^^
The girl is adorable, with slanted eyes, a headband, cute tanned skin, and a tsundere character.
The boy isn’t bad at all, tall, glasses, a comforting air of self-confidence that doesn’t match his “kinda disconnected from common sense” nature.
And their sex is really good too… save for the abominable censorship, against which I have no choice but to warn you, to be honest.

I hope you may enjoy it, and thanks a lot to NecroManCr, this awesome vanilla-centric scanlator! ^_^
