"I'm alone, if you want to come over."

It wasn't too long after he sent the text that Rin came. She entered the room and leaned against the door with her hands behind her back, eyeing him with head bowed and cheeks flushed.

"Hey." Kyousuke rose from the bed and came over to her. He gently grasped her chin and tipped her head up, then leaned in and kissed her on the lips.

A faint sound issued from Rin's throat.

Kyousuke pulled away, looking into her eyes. She had a dreamy look and her lips twitched at the corners. He pressed his lips to hers once more, letting them linger for a moment. When he drew back, he reached out to lock the door.

"You made sure nobody saw you come, right?" Kyousuke had already cautioned her, but it didn't hurt to make absolutely sure.

"Of course I did." Rin frowned. "You keep telling me to be careful, to make sure nobody sees us and stuff. It's like we're ninjas having to sneak around or something. Is it really such a big deal if I'm seen coming to your room? Nobody's going to care."

"Still, we've got to be careful, Rin. If we were found out, it would be really bad, you know. That's reality." Kyousuke cupped her face, running his thumb over her cheek. "I don't even want to think about what would happen if we were caught."

"Okay, okay, I get it already. You don't have to keep lecturing me." Rin's forehead creased and she pursed her lips. "So... are we gonna do it then?"

"Sure. My roommate isn't going to be back for a while so we're safe." Kyousuke stepped back. "You ready?"

"Ready as ever."

And so, the act of lovemaking began. Neither of them hesitated as they made love to each other, but deep down Kyousuke couldn't help thinking about it.

Their being siblings was not a fact they could simply ignore. Society would never approve of them being together. And yet, because of these feelings they harboured for each other, they carried out these sinful acts behind closed doors.

Rin's face flushed with pleasure brought on by his exploration of forbidden crevices, her moans resounding in his ears. Even as he was plundering territories that should have been barred to him, Kyousuke felt no remorse.

They wanted it, no matter the pain that it could end up bringing to them, and they would defy reality for as long as possible.
