Sorry ff
Ff
The only name that comes to mind is Friends Like a Lover, but there’s another one I’m thinking of, just can’t remember the name.
Immoral sandwhich
Kedamono Hatsujouki!! was the name of the one I was thinking of. Bokura No Mitsudomoe Sensou is also a good one. Also, I can’t remember whether or not the uke is shy, but at least I met two of the criteria.
Does anyone know any BL (yaoi) that contains a threesome with two aggressive semes and one sandwiched shy uke? (I also don't mind fanfic recommendations)
