Once Twins now are one in another world

This is a recantation story about a pare of Canadian twins Thomas and Samantha Brown. They died at the same time shortly after they had a fight that they often have. They are then reincarnated as the first ever demigod child of a goddess. This is a story of adventure as they slaying bad guys and monsters as they build their harem including a variety of humanoid race and genders. This do's have sex sense in it but it is an adventure book and yes there will be lots of action both fighting and sex after The MC grows up that is. Side Note: Any rape seances will just munched and not described in detailed and it not the MC doing it be a bandits or something like that and the MC has to save them or something along those line. And any NTR is only done to couples that are into that and not forced the MC never focuses him/her on anyone she despises that kind of thing and those that do those kind of things. The MC is not a home wrecker the only exception is if they are in a abusive or neglected relationship.
