From what i can recall of it, it was a about a AV cameraman who was either bored or trying to find inspiration and ends up finding this boy. I don't think he'd ever had sex with another guy before. They end up doing it and he was filming most of the time. His plan was to send the video out but he's like, "Fuck it," and basically deletes it and then asks the dude he films to go out with him.

Could be the story "Stay" from Rumble Rush.

I think it’s Immoral pure love by Tsukumo Gou.
