Noraneko no Shokutaku
This mangaka is the queen of gentle feelings, I love both stories - they are connected, set in the same universe. Stray cat being lured into a good life with tasty food and gentle care is one of my favourite tropes, as is the older uke silently loved by the younger enthusiastic seme. These are sweet, sweet stories, no graphic sex, but sex still happens and it's portrayed intimately (the way Minakami-san's blue eyes get an even deeper shade when aroused during sex and Isaki-kun's strong back, oh). Kure-sensei is a mangaka to watch out for, her stories deserve a way better rating (this one currently sits at 8.6 which is frankly a crime, get better taste, losers).
