As one gunslinger would say in this case "this hentai's is pretty good".
Although it's giving me blue eyes by the amount of blue balls the protag gets, it's too fucking much. But the women around him are worth the trouble. Thing is, our doctor friend is one asking away from getting it, but MC sure don't seem to be capable of doing it. The girl friend who is sticking with him for the teacher gotta get somethin' soon, or else her presence in the story will be basically null (besides poking at the protags rival for being his sister).
Except the panel where we see her from the back and her bottom seems... small, the anatomy is a high point as always in this chapter in particular, and using monkey or animal mentality do establish dominance is a spicy concept that fits the story and art very well.
As much as it pains me to wait so much for new chapt. translations I wholeheartedly thank those who put the effort on it!
