can someone recommend me some Doujinshi about zoro and sanji hehe pls..

These are some of my favorites (anything by Rom-13 and Nari basically) but just a warning that some are pretty violent.
http://www.mangago.zone/read-manga/one_piece_dj_lie_and_demon/ (has implied minor characters death)
http://www.mangago.zone/read-manga/one_piece_dj_yuigon_wa_Iru_ka/ (minor character death and talks of one of them dying)
http://www.mangago.zone/read-manga/one_piece_dj_boukyaku_countdown/ (this one has canon typical violence)
http://www.mangago.zone/read-manga/one_piece_dj_unwanted/ (yakuza expected violence)
http://www.mangago.zone/read-manga/one_piece_dj_pink_noise_babies/ (this one is more fluffy but it does have canon typical violence)
http://www.mangago.zone/read-manga/one_piece_dj_spit_out_your_soul/ (rape but it has a happy ending)
This ones don't have violence
