Male pregnancy story ideas

I've been thinking of writing a story around the following idea: A seemingly normal teen guy is in the closet about liking guys, and one day at a camp or a sleepover a horny gay teen seduces him and tops him. Over the next couple of months, the protagonist's body changes in unexpected ways - breast growth, swollen belly and he gets morning sickness. Eventually a doctor diagnoses him as pregnant. He's shocked to discover part of him is actually pleased. He keeps the baby and his body keeps changing. At the end of the story, s/he's nursing the baby.
Suggestions, ideas, comments? Anything anyone would particularly want to see?
