Koohii stories:

1) [desmidus] 4-2-2008(413): The 69 position allows both parties to mutually give themselves pleasure.

2) [zazen666] 4-9-2007(37): If you can combined your walls with another house's walls, both houses would mutually benefit, by the increase in size….

3) [FoxintheStars] 20-8-2010(16): Mutually means "You and You together"—two katakana ユ (yu)s interlocking top and bottom.

4) [liosama] 4-12-2008(16): It feels better to imagine two elbows linked together in mutuality.

5) [fuaburisu] 10-10-2005(10): Pictograph, see book. To me this kanji looks like the T and L of mutually (in the first two strokes) mirrored upside-down just like the King/Queen/Valet of a card game. The two L's of mutually are there to remind you the pair of TL's are mutually joined by the L's (i.e. “two times T and L, joined by the L's”).
