Fella's Things

The first manga that I want to find is "You're realesed from the collar" or "Teareble collar".I couldn't find and I would want to read it if I can.It looked interesting.
The second manga that I want to find is one that I read.The story is about a introverted sucubus that is very old(I thing 1000 years old or more) and she made an app that would help her gain vitality from man.The first one that she tries the app on is an office man or something similar.She found out through the app that his kink was anal massage.He goes with him to "maximum level" then leaves him.The second man was a college student(or high school student) that was reading lewd things in the subway.The sucubus found out that his kink was being violated in the subway by a lot of men(it was a specific termen for this,but I forgot it).This was all I read at the time(it was work in progress)
I hope that someone can help me!

I read a few mangas that I forgot the name of and I'll ask here for those.I hope someone can help me!
1.This is a story about a cameraman that one day was asked by a man to film him and his partener having sex.He accepts because the pay is generous and is asked to only film for them.The man who asked was the dominant one and the partener was the submissive.He films them a few times,then is asked by the dominant to let him tie him with rope because he wants to try bondage with his partener.When the dominant was done,his partener came and the cameraman has to film while having the rope tied under his clothes.The submissive thinks the cameraman wants his partener and tries to stop,but in the the dominant one and the cameraman get tigheter and we get a side-story with the submissive one and another boy who is in college,I think.
2.The second story is a one-shot.Two man live togheter and one day the dominant one says to the submissive that he wants to try bindage.The submissive doesn't want to,but he is forced(a little bit) to try it and the dominant one gives him aphrosdiac(that drug that makes him horny,I don't know how to spell it).The submissive likes being tied up,but,plot twist,he didn't take that drug,he took a normal pill.At the end of the story,there is a page with informations(not many)about the bondage fetish.
3.The third and final story is about two cousins,one older than the other.The older one gets his arm broken saving the younger one(I'm not sure)and it takes his arm 2 weeks to heal.He breaks it 2 more times and in that time,the younger cousin helps the older one.They get togheter in the end.The younger one is in high school or collage and the older one is a teaching calligrafy(sorry if I fidn't write it right).
Thank you in advance!Have a great day!

I read a yaoi manga a few weeks ago and I forgot it's name -_-
The manga is colored and has around 6 chapters.It's about a parent named Agatho(or close) who helps an orphan boy because he sees himself in that boy.But Agatho didn't know was that that boy loved him.One day,this boy kidnapps Agatho and takes him to a cult or something similar to make him a "vessel"(vessel meaning making him a sex toy or something similar).This boy wanted Agatho all to himself and when the boy takes Agatho out of that place(after Agatho begs him to and promises to stay with him)they stay together peacefully for a while...Until the boy drugs Agatho(he can't walk or speak anymore),thus Agatho becoming his and only his.That's then end.
I hope you can help me!Thank you in advance!
