This was a fun, not too serious story about a proud gay theatre major slowly falling for his best friend's girlfriend's not-so-straight football(-living-eating-breathing)-playing twin brother. 
 Danny doesn't meet Lance under the best of circumstances, but Lance is really drawn to Danny's occasional feminine look. Lance sort of creeps Danny out, but Danny can't stop obsessing over him for some reason. When they discover a mutual attraction, even though Lance freaks out at first whenever he's reminded that Danny is a man, it doesn't take too long for Lance to get past that hang-up and start playing around. 
 Danny's experienced at having one-off flings, but he doesn't do relationships. He thinks it'll be fun and a challenge to be Lance's experiment, but he knows that Lance wants to go pro with (American) football, which means not letting anyone even suspect he might like Danny. And Danny'd perfectly fine with some no-strings-attached fooling around. 
 Only it doesn't exactly stay no-strings-attached. Lance likes to cuddle, and he looks at Danny like he worships him, and it does things to Danny that Danny doesn't notice creeping up on him until it's too late. When Lance starts pulling back, Danny wants more and knows he can't have it. Lance can't be open about Danny because that would kill Plan A, and Lance doesn't have a Plan B. And Danny can't continue with things as they are; it hurts too much. 
 The story is told from Danny's first person POV. The reader can tell from occasional statements made (e.g. "At the time, I thought...") that the story is being told from a future point in time, but it would have been nice to know earlier in the story how far in the future it is. 5 years? 20 years? 40 years? (view spoiler)[It's 3 years. (hide spoiler)] 
 I felt the progression between Danny and Lance felt very natural, especially considering how they got off to a rather bad start. There wasn't anything earth-shattering about the "out for you" aspect, but it was a well-told story. (It shouldn't have taken me 3 days to read it. I wanted to, but life got in the way.)
