There's a lot of untranslated text in this, and it's relevant dialogue (though some of it is interwoven with moans and screams). Examples: pages 5, 18, 22, 23, 25, 26, etc.

A lot of untranslated text? Probably. Most are sfx and moans (like you stated) which I try and translate into english but imo leaving it in japanese is fine since it doesn't really add to the dialogue/story imo + I do this casually so it depends if I can be bothered to. Another reason why there's untranslated text is because some of the characters are hard to make out for me since I'm not a native Japanese person. If you can read it, then feel free to post the translations here and I'll edit/update it at a later date. But just to note, this is my second translation and it was really for a mate of mine so I'm really not that fussed if it's not perfect as long as the main dialogue and story can be understood.

What I can kinda gather from the examples you gave:
page 5 - bottom right panel: guy on the left - whoa, whoa, whoa... guy on right - kawakami-sensei!?
page 18 - hard to make out, ataru so something about hitting?
page 22 - white text: something like "use it wisely?" a few characters I can't make out. black text on bottom right panel: UNDRESS or TAKE OFF
page 23 - I can't make out the japanese.
page 25 - I can't make out the japanese.
page 26 - top speech bubble: something along the lines of "I really grabbed it.~"

but yeah feel free to correct me, I'm still learning! :pepehands:
