She decided she was going to something special tonight, but wouldn't let on what it was. I let it slip that I was feeling somewhat randy so I would be ready for whatever she had in mind.
Later that night when it came time to claim whatever mystery pleasures she had concocted for me, I approached her from behind in the bedroom, encircling her waist with my arms. She deftly escaped with a grin on her face. "Don't get any ideas, Sweetums. Tonight I'm in charge and I make all the decisions. Understood?" She said it with both a note of authority and a sly grin, so I wasn't completely sure how serious she was.
She told me to be ready when she came back from her shower. I wasn't at all sure what "ready" meant, so I got under the covers naked. Whatever she had planned was exciting me already, even though I had no idea what it was.
She same back into the room wearing her big, fluffy robe, which was strictly utilitarian; nothing appealing there. She told me to scoot over to the middle of the bed. When I did, she climbed on top of me and grabbed my wrists in hers and she pulled them up over my head where she secured them with restraints. Restraints? Where the hell had she gotten restrains, how had she hidden them from me, and where did this come from? This was so out of character for her.
"Comfy?"
"I guess. I just wasn't expecting anything like this."
