I grasped the left side outer fleshy lip and pulled it out and away from my box, revealing a 2-3 inch area of slippery pink skin. I tapped the exposed tender area 3 times lightly with the ruler and lost contol of my self. I pulled the ruler back and landed a painful slap onto the wet inner skin. I bit my bottom lip and let out a strange noise as I massaged the sting into my soul. I switched hands and pulled the other lip out and landed a stinging blow right away. GOD it hurt so good. I laid back onto the bed and started pulling on the fleshy blood engorged lips with no mercy. I grabbed onto both lips with my right fingers and shook roughly back and forth until my fingers slipped off. I was so damn hot. I had never felt so turned on before. If I would have known I could feel like this, I would have started this a long time ago. I brought my hands up to my breasts and squeezed them to my chest with all my strength while pinching my nipples. I found the ruler and pulled my left nipple up towards the ceiling and began rapidly swatting my breast meat hard with the ruler, moving around to make sure I covered every inch. I had lost all control but kept swinging through the pain. My nipple slipped out of my grip but I didn't stop the striking with the ruler. One hard swing brought the ruler directly onto the end of my thimble sized nipple, sending a powerful jolt of pain screaming through my aching breast down into my pussy. I clenched my teeth and screamed through them as I exploded into the wildest pulsing orgasm I had ever experienced.
