Nande Neteru Ore no Chinko Nametano
The title Oh wow, an all-in-one update. Thanks Yun! *Spoilers* I'm just surprised the seme wasn't surprised that the uke knew everything lol. Also, I find it funnily cute (though very unbelievably stupid) that the seme never had any bad intentions when he was sexually harassing the uke. He just straight-up accepted what's happening in the bl manga he's reading as a "good" reference

Seme has a great helping hand, huh
My Quiet Best Friend's Just Tongue-Tied
That shooting star ain't a star, it's a different shoot. Probably from the gay gods /* I only read ch 1 and 6 lol. I did understand everything that happened, so I probably didn't miss out on a lot except for the cringe "rock my world" everyone is talking about I may or may not read the whole thing, though I probably won't since ch 1 was already enough to make me cringe lol */

Same comment as the Santa story, except this is worse because the smut is just eh. I'd like to say it's because it's too short, but all of other Echo's works are one shots and managed to capture the best scenes of a story (not always, but you get the point). On the other hand, this actually reminded me of Tsugumu Logic (sorry for the spoilers) where there's a gang rape club raping new members as initiation. This one though, there's only just one rapist in the club. I'd probably akin this to Juvenile justice's gang rape club where the victim isn't really initiated to join the club, just used.
