The lovely Larrkin has written two stories in the post-Homecoming 4 universe. They contain m/m spanking, so if that doesn't ring your chimes, please move along. Both are wonderful! *happy sigh* Links are to fanfiction.net

• A Special Gift of Attention. Mugen recounts a promise given and forgotten. He agreed to let Jin and Fuu do...what! Jin/Mugen/Fuu.
• Like a Gift. Mugen is acting up more than usual after his birthday spanking and Jin decides to do something about it. A sequel to A Special Gift of Attention.

• Buisness as Usual Sidetrack Ten Sidetrack. Wherein Mugen is naughty.
