Pretty good, him seducing his mother definitely, fucking her harder and harder, cumming in her... i loved ending of chapter 4, very good two scenes, and really great dialogues, with lots of "oedipal/taboo" dialogues and thoughts, especially from "son" character. I really liked it, art and positions and overall sex was pretty good too. I think "determined son and doubtful mom" is a situation that always works in a fantastic way, best possible taboo combination. Hope for a great ending, because end should be near, probably with impregnation. All in all, it was kind of long and sometimes frustrating, but this ending is repaying us for everything, so kudos and congrats to Mandologica for a good job. Now hope to see another story with another character similar to Y3df "The tan" story (as Katherine here) and that is - Jenny, she was fantastic , grumpy, bitchy, bad-tempered mom who then get fucked hard and good by her cheeky, insolent son - fantastic situation, fantastic character, hope Mandologica will do something similar.
