1.They're couple, living in the old apartment/dorm. When they go outside, they always saw the crack on the wall of the dorm. And said something about "how old the building..."
Apparently, they're the caused because they're having sex everynight and make the room shaking. And making a crack more bigger. And they never realised about it.
2. A manga that he was force by his drunk s father to sell his body then he found a glasses guy that buy him for other reason.

http://www.mangago.zone/read-manga/mae_yori_mo_dare_yori_mo/ (1st couple)
Its a story about s boy that live on a Island and a guy comes in and out investing who is bringing guns onto the island illegally. But, those that live on the island does not know anything outside of the island like how time has change in Japan. Since, those that are on the island is living in edo era. Any idea? Would like to read it again. Thanks
If i remember correctly:
It was during war era/ solider/captain.
The uke was capture by the seme and was being torture/hardcore sex/S&M because uke was working for the other side. But, in the end they were just role playing the torture part. When they where done with the whole boom boom they went back to their post.
