I'm sorry to those who read this unknowingly.
I, for one, found what I was looking for. A fun smutty yaoi with gorgeous sexy leads with a nice helping of uncle-nephew incest. Don't bash the incest kink. If it squicks you out, the back button is just a click away. Fiction, people. Fiction.
Also, YASS to the older-uke, younger-seme tag.
Please check tags before reading so as to avoid getting into something you would rather not (such as incest), and essentially giving this story an undeserving grade just for your bias. Grade it for the story and the art, but don't grade it according to your squick.
Summary: Azuma (the uke) opens the door one day to see a hot dark-haired man standing on his doorstep and claiming to be Taira (the seme), Azuma's nephew. It's been 6 years since they'd last seen each other and Taira has since grown from being an adorable kid to a sexy guy.
I got what I was looking for, and enjoyed it. There was some dialogue that made me giggle, and the build-up to the sex (which happens in the last chapter) wasn't too rushed. There were some parts that felt sincere and heartwarming, even if it was a little cliche.
I loved that the seme was bigger and a tad bit taller, but still unreservedly adorable which the uke also saw and liked.
I loved the smut fans self. Clothed sex (which was a hugely pleasant surprise) is a kink of mine. So much YES, but a little too short and I was like Nooooooo.
It doesn't end with their first time together though, and I loved the uke's rumination of how cough big cough the seme was. They talk about what happened for a bit and the ending is adorably sweet.
10/10 would read something like this again.
