"The blue-haired comes closer still, while the blond gets back on her knees, looking straight at me the whole time."

The correct form would be "blonde" because it's referring to a female. Shows up a few other places too.

"While they are engaging in a heated discussion, my mind is wandering somewhere else, this woman is once again impressing me by doing things that seem to be completely menial to her."

This isn't a typo, but a word choice suggestion- "menial" has a particularly negative connotation, basically meaning 'servant work'. "Trivial" is an alternate that means easy to the point that it can be done effortlessly- as the next page states.

"Yeah, that's where we have built a really big and boring place long ago."

Drop "have", this is an active past tense, doesn't need the passivising participle. (watch me butcher grammar too)

"The smells emanating from our heated bodies is all over the room, this is probably as exciting to me as it is for her."

Change 'smells' to smell for subject-verb agreement.

"In a finger snap, a rope that glows purple appears and bonds the intruders together, back to back."

"bonds" should be "binds"

"She stops the movements she was consistently repeating so far, only to display a mischievous grim for a split second"

"grim" should be "grin"

Meriandra: "This is it, we part our ways here."

Can drop "our".
