Good smut besides the waterworks. She does have a great body and personality. I do wish they tried a different position besides missionary but it's not a big deal.
I noticed some typos: 1) on page 14: "As excepted of the great Yuuki Rio.." (obviously, it should be "expected" while the two dots at the end should be three dots to make a proper ellipsis). 2) on page 45: "sheriously" instead of "seriously".
