Normally, to have something like a holiday would be kind of bittersweet because it meant going home and not being able to see their friends every day, but winter break brought with it a certain sense of excitement for Kyousuke and Rin.
Sure, the days were almost too quiet with just the two of them, though Kyousuke did his best to think of things to do so boredom was never an issue, but being alone had its advantages.
No having to sneak around. No arranged meetings. They could hold hands, kiss and touch each other all they wanted. With all the free time they had to themselves and nobody around to potentially disturb them, they didn't have to worry about getting caught.
Kyousuke felt a giddy thrill as he sat atop his little sister on the couch and slowly pulled away her layers of clothing. Rin gazed up at him, her face flushed a rosy hue. As he rested his hand on her exposed breath, he could feel her heart throbbing away beneath her soft skin. He leaned in to kiss her lips and dived right in.
There was no risk. They could carry on as they liked, uninterrupted. As much as they missed their friends, they were so glad to have this holiday all to themselves.
