forgot which chapter :D Sorry,

Honestly, tentacles aren't my thing. BUT there are these 2 mangas which just won my heart & refused to let go despite that slimy concept.
http://www.mangago.zone/read-manga/null_null_gintama_dj/ <-- 1 of my personal fav!
http://www.mangago.zone/read-manga/uchuu_no_mozuku/ <-- a quirky & NOT so messed up one by the Queen of twisted genre, Harada.
You can check back stage rei wears one
thanks a lot~~~ i will enjoying those~~~ (๑•ㅂ•)و✧
actually, the tentacles i've read are not from this site (and YES, hentai websites has yaoi manga but it's majorly porn-oriented)
so, if i hunt down those i read here in mangago my fetish list would fill up easily so i only listed the ones that i really liked http://www.mangago.zone/home/mangalist/44110/?filter=&page=6
Can anyone suggest yaoi manga about tentacle, apron, whichever it is. Both also can. But if it is okay the one that is cute drawing. Not big build couples.. ヾ(☆▽☆)
