   Summary

   Osomatsu has known for a while that he has feelings for his second brother, but is trying with all his might to hide them. However, when an innocent night of smoking and talking takes an unexpected turn, Karamatsu finds out about Oso’s feelings, while Osomatsu discovers he’s bit way more than he can chew, and gains a few new kinks along the way. Now he just has to find a way to explore this new side of Karamatsu and himself, without the rest of the family finding out. Easy peasy…right?

   Or: A self-indulgent PWP (that grew an actual plot) because top!Kara gives me life.
