Welcome to the dark side! Looks like @conman has delivered a great list, so there is little else I can add, but Viewfinder and Tightrope have some pretty obsessed semes too.
welcome ヾ(☆▽☆)
make use of all the advantages after signing up^^

http://www.mangago.zone/read-manga/futari_no_musuko_ni_nerawarete_imasu/ (twin semes in this one)
http://www.mangago.zone/read-manga/sex_pistols/ (multiple couples and stories that are sort of interconnected; all the semes are possessive)
