Stealing Ronan: An M/M, sister's boyfriend romance

Stealing Ronan wasn't the plan. I'd never imagined I'd steal a boyfriend from my sister, but when I saw him strutting to my couch with his perfect body, gorgeous face, and that mouth-God, that mouth, it was like he was plucked from my wettest dreams and brought into my life just for me. Lusting after a straight guy who's dating my sister is a problem in itself, but the bigger problem comes when he's invited on a family trip with us for Christmas. Just as I thought I was doing a pretty good job ignoring his soft lips and curious gazes, we're hit with a furious blizzard, leaving me and Ronan locked up together. Alone. We're only snowed in for two days, but things heat up quickly, because it turns out I'm not the only one with a fascination.
