I loved all of it, but I think the moments that stick the most are those with just Mr. intuition and me. I remember after our first encounter with another couple, when we retreated to our room for the night, how Mr. intuition nearly attacked me. And another night when, after a full-swap play date, we closed the door to our bedroom and he couldn't get me on the bed fast enough. I remember loving the scent of this other woman's body on his mouth when I kissed him and the haze of her perfume on his skin. I can't put my finger on it, but it's this alien "other" smell of excitement that lingered on his body, like the smell of electricity. But it's distinctive. Your partner just "feels" different after he's been excited by someone else, like the way perfume smells different on different people.
If you haven't guessed, scent seems to be my strongest sense when it comes to memory.
