I thought the story was quite boring. Nothing new and the artwork was not good. Other than how the women were drawn, men were a bit out of proportion.
Story is about an extremely handsome MC who has hots for his step-sister who is conveniently no blood relation. FMC is boring and stupid as hell, but her step-father (MC's father) also has hots for her. There is an evil young step-mother who makes life hell for MC and FMC. Ofcourse that does not stop them from getting it on. There is hardly any story here other than some college girls wanting to be with MC and getting rejected (after the dirty deed of course) and being catty about it. After an aborted rape attempt on his step-daughter the father has a mini-harem with his wife and some trollop. MC ends with pregnant FMC and it ends. Silly stuff really.
Everything about this work could have been better with more effort and imagination. But at least it was a short work. Perhaps it is author's first work.
