Tickle Frustrations.

I am frustrated. Years ago, before my wife has her medical issues, we met a guy into tickling. He and I chatted and my wife agreed to be tied and tickled. He came over, we tied her in shirt and shorts. I sat and watched as he slowly tickle her from pits to soles. I got so turned on,watching a guy tickle her. I even asked if she liked him tickling her, she said yes. If she wanted him to stop, she said no. She even let him lift her shirt and tickled her tits and nipples.Now, no tickling and I have to chat behind her back, even with gay guys about tickling but have to sneek to hopefully get tickled.
