Almost Heaven (Exception to the Rule # 1) by Kimberly Gardner (MM)

(Only have PDF...it wouldn't convert properly into mobi or epub)

When Chris meets Kevin at his brother's school, he instantly gets hot for teacher. He can only hope that the sexy guy is gay. Later, when Kevin shows up at the gym where Chris works, Chris is sure he's got him hooked. A shared kiss is absolutely electric but then Kevin turns tail and runs. What the hell? Maybe he's in the closet.

Yes, in fact, Kevin is in the closet, Deep in the closet. He has to be. He's going to be a priest. While he's very attracted to Chris, he simply can't pursue it. Giving in to that attraction would ruin his life. Still, he can't deny what he feels so instead he vows to stay away from Chris.

But steering clear is not so easy when what you've found is Almost Heaven.
