Gosan no Heart
I like the story of the heart of miscalculations (chap1-3, and 6). Great seme
Owaranai Fukou Ni Tsuite No Hanashi
Great sequel to Gosan (the heart of miscalculations), and it's interesting to watch how both brothers have such different but similar partners.
Sekai wa Kimi de Mawatteru
They are good couple chapter stories, but I think they're to short to really sink my teeth into. Promise, not a yaoi pun.
Keep Out (kisaragi Hirotaka)
good plot for a shorter yaoi, and some sexy scenes filled with a lot of character development. I really liked it
Uchi no Tantei Shirimasen ka?
Doko ga Ikenai!?
I liked it but I feel it needed more, to explain why Ikasu was getting drunk by himself when his cousin said his little brother was already grown up, and whether the brothers getting drunk remembered it. Too much unexplained
Ore no Ushiro ni Tatsu na!!
Loved the strong mature seme's getting taken over by you, and small uke. If you want smut, it's plentiful. But chapters need to be longer, too short for a multiple story one.
Kuroneko wa Shippo de Amaeru
I'm a big fan of the kuroneko series, and I liked this one too. But I guess the only cat was the real cat :)
Aragau Netsujou
It's a cute and fun perverted manga, about 2 chapters each for each story, but stories have a beginning and an end. Lots of fun sexual perversions and smut
