They met many times, alone. The latest one, when Jack was over at a friend's house, was the last time they met as friends. Emma had gone to sleep early for a test, so she had no idea Dean wasn't there. Castiel's house was big, fancy, and lonely. He said that he had inherited it from his father. They ate dinner together, and finally something happened. Dean was saying goodbye, about to leave, when Castiel kissed him.

Dean stood, frozen in the doorway, his hand on the knob. "Cas… I think you got the wrong idea." He said. "I'm not…" But Dean couldn't turn that knob. He wasn't going to leave anytime soon. He turned around, kissing Cas.

"We should discuss this." Castiel said.

"I don't have any STIs." Dean said. "And I do have protection just in case."

"No, I meant how this will affect our children." Castiel said.

"Oh." Dean whispered, pausing. "I didn't think about that. I didn't think about anything. This literally just happened seconds ago. We'll figure it out later."

"Okay." Castiel said. Dean pulled his coat off. They ran to Cas's bedroom, which had a four poster king bed, and Dean laid down on his back. Cas pulled off the rest of their clothing and felt Dean's warm skin against his own. They rolled over in the bed, tossing and turning through the night. Dean felt, for the first time ever, truly blissful.

He knew he had messed up when he woke up to the sunlight streaming into the room. He nudged Cas, who looked at the clock, which read '11'. "Oh God."

Dean couldn't find his clothes from the night before so he grabbed things from Cas's drawer. Cas rushed down the stairs to his car, and Dean jumped in his. Cas was supposed to pick up Jack a hour ago, and Dean was late for work.

Castiel rushed to Jesse's house. "Hi, , I'm so sorry, I've come to pick up Jack."

"You're Jack's dad?" Mrs. Turner asked.

"No, I'm his uncle."

"Oh, then he left with his dad an hour ago."

"His dad?" Castiel felt his heart beat go three times faster than usual.

"Yeah, his dad. What's-"

"I have to find him."
