You didn't know what you were in for when you got home and found your birthday gift waiting for you on your stoop. It was a small box wrapped in bright paper with an elaborately tied bow. As you looked closer, you saw that the bow was tied up with the same knot I used on your wrists last time we'd been together. Your heartbeat increased ever so slightly as you check the tag. "Go inside, put it on, go into your bedroom and get on your knees. -W" the tag read. You glanced around but didn't see anyone and hurried inside.
Inside, your curiosity got the better of you as you flung your coat on the floor, not evening noticing that you missed the hanger. You tore open the paper and your eyes widened as you saw that the box contained a set of green lacy underwear, bra, and a dark satin blindfold. You felt yourself getting wet as you imagined what might be in store for you. Dutifully, you went into your bedroom, stripped down, and put on your new outfit. You got down on your knees and slid the blindfold over your eyes. Everything went dark.
As you knelt blindfolded, you let your mind wander to our last encounter. How you squealed as I slapped your ass. How you gasped as my cock entered your pussy, your face pressed down against the carpet, unable to move with your hands tied behind your back.
