送られてきたブルーレイ1 始まり

その中には若い男性が緊縛されて責められる「SM動画」が記録されていた。しかし彼は明らかにマゾヒスティックな「快感」を味わっているようだ！
はじめは分からなかったが彼は昔、俺と肉体関係を持った血の繋がらない弟、「薫(かおる)」だった。
俺は薫を弄んだ後、捨てた。そして数年経っていた。この動画は俺への復讐なのだろうか?
「俺」の独白文が付いたストーリー仕立て・差分CG集です。

One day, a Blu-ray disc was sent to me without the sender's name.
The movies in it were "SM adult-videos" in which a man was tied up and teased. But he clearly seemed to be enjoying masochistic "pleasure"!
I didn't know who he was at first, but he was "Kaoru" who had a physical relationship with me in the past and he is my brother-in-low! I played with Kaoru and dumped him.
And a fewl years had passed. Is this video revenge on me?
This work is the collection of difference CGs with a man's monologue.
