OT3 prompt: A and B are busy kissing when C comes up from behind B and wraps their arms around B’s waist, pressing kisses to B’s neck and soon sliding a hand down B’s pants. Cue A getting frustrated and pouting because B is suddenly too distracted to do anything besides gasp and moan, and A was hoping to get to kiss B a while longer.

(Bonus if A finds a way to get back at C later.)
