1. It was a team fic. They weren't in the tower, I think they were in tony's mansion in CA. The power was out, and they were all in the basement, I think. They were using tony's arc reactor as light, and it was really hot so they got undressed. Then when they were back at the tower they still got naked around each other. I don't think there was a pairing, but im not sure.
2. Had no luck over at Steve/Tony search, so I thought i'd post this here.It was an mpreg with Steve as the Pregnant one. I think it was comic-based but am not 100% sure. I don't remember exactly how he got pregnant, but I do remember Steve and Tony had a fight because Tony was flipping out over it and then Tony thought the fight ment they had broken up and was depressed till Steve set him straight. There was also a scene where they went baby shopping and Tony teased Steve about having "Pregnancy Brain". The baby was a girl. I don't remember her name but I think she had Tony's Hair and Steve's Eyes. There was a scene at the end where Steve brings her to see Tony at work.
