HJMO-242 - First time SM: Breaking a naive girl

It's a mystery why #4 ended with just irrumatio, and the context for #5 going all the way makes no sense. I don't know what I'm supposed to do with a video where the girl doesn't even wake up.

A work featuring amateur girls experiencing SM for the first time. Five girls appear, but only the first and fifth go all the way; the others just end with oral. Personally, I like the concept, but I wish they had all gone all the way. The second girl's nervous reaction was good, and the fourth girl is my type. She appears in other works, but I don't know her name. If anyone knows, please let me know.
