I often filmed videos with my wife for fun. Recently, I found myself unable to get an erection properly and couldn't satisfy her anymore, so I asked my junior colleague to have sex with my wife and let me record it. At first hesitant, my wife gradually became aroused as the junior kissed her and groped her breasts, and watching her react this way made me increasingly excited. I was overwhelmed with complex emotions and intense arousal as I filmed her getting her pussy licked, stimulated with a vibrator, becoming wetter and more sensitive than ever, giving a blowjob while taking the junior's cock in her mouth, and showing pleasured expressions as he penetrated her. Seeing her like this—completely unlike her usual self—I lost all sense of control.
