Just a minor pet peeve, but I do get annoyed with ecchi series that can't keep consistent proportions for the drawing of the character's naughty bits. Like in some panels Touka's boobs are as big or bigger than Kaho's, while others they are clearly smaller.
This chapter in particular, with the unveiling of Shirasawa's "lightsaber", it just seems random for it to suddenly be a magnum dong, when previous chapters like the Touka BJ, Ekoda couch scene, Kaho jacking him off on the bed, etc. there was never anything remarkable mentioned about it. Like at the very least if Ekoda had been impressed or Touka had trouble with the deep throat, that would have made Kaho's reaction more natural.
Again, I know this isn't peak literature, but if it's going to be a ecchi/fanservice heavy series, I would appreciate if the author was more consistent with the depiction of the characters!
