Looking for a specific yaoi and a bonus

It was part of a collection of one shots, I believe, and I'm almost certain it was the last one in the book. The uke was a teacher who had just been assigned to a rural high school. I think possibly it was set in the not-too-distant past, as instead of a suit the uke wore some sort of traditional clothing. The guys in the class were all tanned and thought he had pretty pale skin. He went swimming with them, despite not knowing how to swim, as a trust-building exercise. They went out to this island nearby and were teaching the teacher how to swim, but kept fondling and crowding him until he was terrified and near(?) crying. Then the leader of the students demanded everyone leave, 'rescuing' the uke, whom he then fucked while still at the island. Sound familiar?

Another one that might be a stretch: I read it on a different site, and have no idea if it's here at all, but any help would be appreciated. It's a guys' school, and the biology club has been dubbed the 'sex' club. Pretty much everyone in it is a virgin, though they all think their school's 'prince' is highly experienced. The truth is he's actually a virgin due to being an incurable romantic who wants someone to love, not just sleep with. One of his kohai's, who is *not* a virgin, figures it out after molesting him in the bathroom, and then cofessess. The sempai is confused and scared by the speed of his kohai's affection, and backs off. This convinces the kohai that his love isn't returned. This all comes to a head at a group date, where the sempai is jealous of his kohai getting along with a cute girl. The kohai is sick with a fever, so at the end the sempai pulls him away with the excuse of sending the sick man home, but instead they go to a love hotel, where they have a bit of a shouting match and everyone's feelings are made clear. Then they have sex, despite the sempai being worried about his kohai's health. In the last chapter the sempai goes to visit his kohai, who is bedridden with the fever and who is questioning if it was real due to his sempai being so cold to him. It was only three chapters long, and the reoccuring theme was "i have a secret", "I have another secret now" and such phrases.
