Uncle seduction episode involving aunt-in-law caught by boyfriend

In an unexpected twist that plays out over several days leading up to New Year’s Eve, things take a dramatic turn when my uncle tries to get close enough for some flirting but is quickly stopped mid-game by our unsuspecting aunt-in-law who catches them together through their open window while they were just about ready to leave after dinner! Meanwhile back home something feels off as soon as we hear loud laughter coming downstairs followed shortly thereafter by more voices entering into what turns out later on was his room where he found himself face-to-face with both uncles which shocked him completely upon realizing exactly how involved these men really are towards her life all along.
