Sam's having a party or get-together of sorts and Dean comes home. They play Truth or Dare or Spin the Bottle, can't remember. They end up kissing after a few rounds (I remember this scene, something about encouraging shouts and disgusted sounds) and later they kiss against the staircase railing or on the stairs or something like that.
Other Truth or Dare/Spin the Bottle recs are also welcome, but I'd really appreciate it if you could help me find this.
Found! The link is in the comments.
