PLOT
A kind and reliable older sister, Mizushiro Ayaka. A younger childhood friend and now my girlfriend, Tsurutani Ayaka. While I'm happily getting along with the two, I wasn't satisfied. That is because I have a hobby that I must keep hidden.
I want to do S&M.
I secretly buy tools for my personal use - stare at it, touch it. And then one day as I was expelling myself of my urges, I noticed that someone had entered my room and saw the secret.
Let's try setting a trap...
I turn to see who discovered my secret. And so, our abnormal relationship began.
