How could this have happened?

Rin was standing perfectly still, staring down at the floor where the offending stick lay by her feet after it had slipped from her fingers. Her knees gave way, hitting the floor with a soft thump. She hunched over, shoulders slumping and head bowing.

"I'm pregnant," Rin whispered, her lips barely moving. "There's a baby inside of me."

Kyousuke's gaze shifted from Rin to the stick and back, his mouth frozen open. How he wanted to believe that this was a mistake. It didn't make any sense. He had been so careful, making sure to use a condom every time they made love and yet, somehow, against all odds, Rin was now with child. There was no question about it. It was his child as well.

He couldn't believe it. He had actually managed to impregnate his little sister despite all the precautions he took. Why did fate have to be so damn cruel?

"What are we going to do?" Rin turned her head up, dull eyes focusing right on him. "Why did this happen?"

"I don't know." Kyousuke hung his head. "Maybe a condom broke." He slowly clenched his fists, grinding his teeth. Right now, he felt so angry at himself. It might have been an accident but still, it was entirely his fault. He was the one who had done this to his little sister. That baby was inside of her all because of him.

This never should have happened. That baby was a product of siblings. It could end up having defects. They had never intended to bring another life into this world together. This was just beyond messed up.

"So, what do we do?" Rin's voice was flat, devoid of emotion.

Kyousuke moved over and knelt down to hug Rin. "It's your choice, not mine."

"What?" Rin's eyes widened. "What do you mean by that?"

"You are the one who should decide. I'm not going to force you to make a choice."

Rin looked away, her lips pursing in a frown. "That's not fair. You're the one who went and put it in me."

"Yeah, I guess I did, didn't I?" Kyousuke stroked her hair. "Sorry. I was so careful. I have no idea how this could have happened."

"So, what should I do?" Rin asked in a wobbly voice. "I just don't know."

"We have plenty of time to think about it." Kyousuke tightened his hold on her, resting his cheek against her head. "I'm sure we'll figure it out as we go."

"Okay," Rin whispered.
