Threesome yaoi please

Hmm, this is tricky because a basic tag search turns up a lot of yaoi that are not about threesomes, and even fewer of them are sweet as well as smutty. You've probably read most of these already.

I wouldn't call this one "sweet", but it's definitely hot .... and you've probably already read it:

it's kinda cute (and hot): http://www.mangago.me/read-manga/kedamono_hatsujouki/
and this also fits: http://www.mangago.me/read-manga/choco_strawberry_vanilla/

I have a threesome list you can check. Some are pwp and others have some story. There is something for nearly all tastes except shots since I don't read that.
