This is a serial that was running this summer and posting every week. High school boy, dad is dead, mother is a young, beautiful blonde newscaster. Boy loses his virginity, and gets a harem, it seemed there was going to be something with the mother in the future.
I know it sounds like a thousand other stories, but it seemed to disappear in July or August. I don't know if the author abandoned it, or I just haven't noticed it.
