NTSU-178 Because my stiff, serious wife and I had been sexless for years, I let someone else get involved through partner swapping.

I tried letting my wife be with someone else, but as a beginner, she was shy and completely overwhelmed. Her usual composed self was gone, and she was visibly flustered. Seeing my normally modest wife reacting so intensely, I regretted my decision and found myself aroused all over again.
