I could hear the door crack open...which was about all I could tell, given that I had an eye mask on. I lifted my head slightly, but that didn't really accomplish much. Nor could I lift it a lot, as my wrists were cuffed together and stretched over my head. I heard soft footsteps on the carpeting, and the rustling of clothing. I felt my wife get up on the bed and straddle my chest. I could smell her perfume--it must be something new she picked up, as I didn't recognize it--along with the smell of her excited pussy, and the feel of it resting on my sternum. Then she slowly inched her way forward, shuffling one leg forward, then the other, until I could feel the heat of her radiating just barely away from my chin. This was, indeed, a surprise!
My wife had called a little while earlier--she was out with colleagues from work--and sounded a little tipsy, which frequently leads to some fun. "I'm on my way home. Put on some music, then go shower and shave, and get the cuffs and eye mask out. Put them all on and attach your feet to the footboard and your wrists to the headboard. I have a surprise for you!" And then I heard her giggle and hang up.
I sprinted to the shower, and jumped in before the water was even fully warm. After a quick scrub, I grabbed the razor and tidied up my cock and balls, making sure I was nice and smooth. I jumped out and dried myself quickly, then shaved to make sure my face was as smooth as my package. I went to the toy drawer and pulled out everything she mentioned, putting the cuffs around my ankles and wrists and then attaching both feet to the footboard. I pulled on the eye mask and then, feeling my way through it, clipped each wrist up to the headboard. My cock strained towards the ceiling as I waited in silence.
