Kinshin Souai ~Haha ni Koi Shita Boku by Puzzlebox jap

Masaru is a 19-year-old young man who has just entered university. As long as he remembers himself, there were always only two of them in his family - he and mother. He does not have many friends, because Mom is very strict, and he preferred not to bring them home.
Now that Masaru has matured, he began to have “other” feelings for his mother, and he knew that this was wrong. But how far will his love lead, and how long can his body resist?
