Well, this had me pondering the border between SA and Yaoi. The first story had forced sex and the second story had almost-forced-prostitution. However, there was never any explicit scene. Generally, Yaoi will include explicit sex (and, therefore, most readers have that expectation when they see the tag), but, generally, SA won't include any nearly-explicit or sexually mature content. So I was pondering if the Japanese would class this as Yaoi or not.
But yeah, if you noticed the tag, it wouldn't meet a lot of readers' expectations.
These are very cute stories and I enjoyed reading them but they are not yaoi but shounen ai!!! thx D
