Making Over Maris by Sabrina York

When über-nerd Jack asks Sara to make him more attractive to women, she can’t say no–even though it’s an impossible task. He’s shaggy and doughy and hopelessly inappropriate. He has no style or emotional intelligence but he’s a good person. And a great friend. What Sara never expects? Beneath all that fur and geekiness is a steamy hunk just waiting to emerge.

Jack takes Sara’s regimen very seriously, working out and losing weight until he feels like a new man. He even complies with her command to shave his beard–because Jack didn’t ask Sara to make him over so he would be attractive to other women. He only wants to be attractive to her. They go on a series of fake dates, each hotter and more sinful than the last. It’s not long before Sara discovers Jack’s secret desire to be dominated and what began as an arrangement becomes something amazing–something that could be real.
