"Hey, Big Brother Xuan Kai… do you want to use the washroom as well?"
I frowned. "Huh? What do you mea-"
But I didn't get to finish my sentence as Qing Yue suddenly pushed open the door of the washroom closest to us and pulled me inside along with her, then slammed it shut again and pinned me against it, a look of lust and desire on her flushed face.
"Hehe… since these washrooms are so spacious… it would be a waste to not take advantage of this, wouldn't it?"
"Qing Yue… didn't we just do it last night…?"
"Maybe so… but that wasn't quite enough. After all, your attention was diverted between all the other girls as well. So… what do you say, onii-chan?" She stuck her tongue out playfully, pulling up her skirt so I could see her wet panties. "Do you want to cum inside your little sister, right here, right now?"
