Oh boy, I was getting behind with Ginhaha, quick, a catch-up repack ^^
I gathered here four works by this artist, namely:
– Afureru Ai 2 (“Flooding Love 2”), in which a girl from Sword Art online called Quinella has group sex
– Gotoubun No Erosu + SP, in which the five sisters from the Gotoubun no Hanayome series (or you may know it as “The Quintessential Quintuplets”) are shown having sex (separately, it’s not group action)
– Menesu De Osananajimi To Masaka No Saikai De Daibakusha, that one is original creation, not inspired by something else, and it’s also the only grayscale work. With broken English, it’s a guy visiting a massage salon, basically.
– Sake To Rokishi No Tabi, in which a pettanko apparently has the habit of getting drunk and sexxed, I should give a loli warning, it’s borderline here
Credits are for Hentai_Doctor, and… well, no clue other than him, sorry ^^;;
