Saimin Kanojo Soushuuhen (“hypnotic Girlfriend Omnibus”) volumes 1-2 [English, 392 pictures], by Ichiyo Moka
Settled adult me looks at “hypnotism phone app” hentai stories with a stern face… But I must be honest, I know teenage me would have busted so many nuts a day at the mere thought of using an app like that. So. Many. Nuts.
So I can’t be too judgemental, allright
In terms of story: a highschool boy not courageous enough to get girls the normal way uses an hypno app to relieve himself with the school’s most popular girl, and later on his sister and another classmate. Incidentally, that awakens the girls to sexuality, once the hypnosis wears off they don’t remember anything, however they’re now more and more often and easily aroused.
Graphically… This is okay. Essentially, vaginal sex. There are plenty of full color pics, with lesser art, while most of the images are in grayscale. The censorship is almost tolerable (so many bars, and they’re too thick damnit), the art does the job without being great. What’s the expression, not great, not terrible? ^^
But I’m unfair. There’s one aspect that was really good, the close-ups on the women’s face. They made lewd expressions, which was nice.
Release credits rae for Crying Cat Translations, Melty Scans, Mintvoid/Lance, and FFFox, thank you!
By the same artist (Ichiyo Moka is the name of the main mangaka in the doujin circle Chocolate Latte), I also share the short colour work called Mizugi no Shoukaku-san wa Ikaga, it’s a small part of a large full colour pack, here.
Recap pages in the 2 volumes point at more works by the same artist, in the same universe, and with other girls, but that looked like a god damn unholy mess to me. I checked the scanlation sites, and, yeah, there’s more. But I’m not brave enough to sort, compile and properly rearrage that whole mess, sorry.
I’m betting on yet more compilation/omnibus gathering those other releases in the future
And now, the download & gallery links

I allowed myself to very slightly recompress the images before sharing. You won’t notice any difference with the naked eye, but now it’s only 156 MB instead of 601 MB =)

Boobs and bars, the bones of good wallpaper lie here.
