Great stuff, a hot milf first getting raped, then getting horny and fantasizing about fucking her son, then getting set up for a threesome with both the son and the rapist..........yup, outstanding :D
@errata Yeah, in any kind of manga they sometimes put the title in english. Also if you curious about the story, not so much to understand, judging by the images alone; some social asistent semi-rape the mother, then when he discover the mom clothes in her son's room he help him to fuck hes mother, and in the process he cure the son's hikikomori syndrome, it's a win / win.
Of course i could be wrong, but i doubt it has more plot than that.
