Couple/Couple tickling story

I'm sorry but does anyone know where I can find the couple tickling story? I cant seem to find it
I don't remember much from it but, In the beginning of the story, the couple meets another couple who is into tickling, they plan for a session and when they arrived, the wife asked the girl if she was comfortable with the husband tickling her and she said no, so only the wife tickled her. That's all I can remember :/ if someone finds it, please tell me! Appreciate it
