This is a new raw of Les Chuu Life, this appears to be an expanded second edition of the tank for the first three chapters, but there are new scenes at the end of chapters 2 and 3 that are definitely worth a look.
I didn't mind threesome that much (and I hate cheating with all my heart), because they clearly got carried away (horny teenagers, go figure) and it was all consented. Author even addressed it (instead of hand waving it as most hentais do) and shown that at least Natsu felt that what they did was wrong. I also agree that I prefer when there is some sort of story and character development than just straight porn.
One more thing in defense of threesome. They are teenagers who just discovered sex and because they are lesbians, they can't tell anyone they are together. So when one of their classmates not only learned the truth, but is interested in lesbian sex as well, I can totally understand them going with it, without thinking and regretting later (look Natsu). If anything I'm happy that this experiment didn't ruin their relationship.
Ok first of all, tongues are not cool. They're warm, body temperature so no. Second of all, if it hurts that means her hymen isn't stretched out enough yet. So just begin with one finger and then work your way up gahd.
I actually thought the dialogue was pretty good. The writing really made their relationship real. I didn't notice any huge issues with the translation, other than not translating all of the author's comments because I love to get that glimpse into the mind of different people. Still, pretty good overall, I give it 7.5/10.
