Most 3D-works have pretty bad grammar and spelling errors. This one of those exceptions to the the status-quo. I didn't notice anything weird about the English during my read through.
The art is also pretty good. The teacher is done especially well because you can even notice the unevenness of his facial hair; you can tell that the artist worked especially hard on it. s/he could have just chosen to make the teacher clean-shaven but Byron challenged himself/herself in this regard. The girls were also damn sexy. Sure, the way that their breasts perk up are unrealistic but damn if my your boner minds.
