Mpreg
Jack watched Ianto bustle around the kitchen. A while back they had discovered that Ianto wasn't fully human. He was part of an alien species that lived longer and was sturdier than humans. Jack knew that they wouldn't have forever but he would take any time he got.
And Ianto was glowing. Not the ethereal glow that he could now emit at will but the glow of someone who was pregnant. Jack smiled affectionately as he thought about how cute Ianto looked pregnant.
Ianto swore. He had moved over to the coffee machine but the baby couldn't have coffee. Jack chuckled quietly. "Do you want me to make you some tea?"
"Don't bother. I'm closer to the kettle anyway."
"You should let me help sometimes." Ianto didn't answer. Even though Jack knew his lover must be scowling right now and would certainly get back at him for laughing Jack had never felt luckier.
