I was in love with Kanna Saijo, a senior who is said to be the most beautiful girl in school. However, she is a tall flower... i had given up halfway because there was no way she would like dull me.

“Um… actually, I… like Ryuuki-kun…. Would you like to go out with me...?"

To my surprise, Saijo-senpai confessed to me.

We, who became lovers in this way, continue to date and develop love. And finally today, I invited her to my house.

I dared to choose a day when my parents weren't there...all in order to cross the line with Saijo-senpai. In the room where we were alone, we faced each other and exchanged kisses. However, when we intertwine each other's tongues――

"…………Hmm?"

Feeling something strange, I let go of my mouth. Then, the senpai had a piercing on his tongue. That is not all. When the senior bared his chest, his nipples were also pierced. What's more—the ominous tattoo carved into his lower abdomen.

I didn't know. Senpai started dating me long ago...
