They seldom show kissing on Loud House. Luan and Benny's in "Stage Plight" remains the only one that was significant and shown onscreen (instead of either showing it offscreen or blocking it away). Even Howard and Harold never have any PDA with each other in any episode, so I think there is no chance that Luna and Sam will kiss onscreen, unless they did it for a "last episode" sort of thing like in Adventure Time or Gravity Falls.
