You are stretched over a wine barrel, held in position by ropes around your wrists. The height of the barrel and your position draped over it mean your ass and cunt are easily accessible for anyone behind you. Your bra hands around your waist whilst your panties are in tatters on the floor near your feet.
I slap your ass with my hand, concentrating my aim on your right buttock. Your skin is initially cool to touch, but warms up quickly. After only a few spanks, your ass gets red. I enjoy the contrast of your pale skin and freshly spanked buttock. I keep slapping your ass until your right ass cheek is bright red and you are moaning after each slap. If I didn't know you I'd think you weren't enjoying the spanking. Dragging my palm against your ass I am quickly re-assured this isn't the case, my hand is wet from your juices.
I position myself behind you and thrust into you. The combination of the restraints, your imagination and the spanking has made you very wet and almost without effort I am deep inside you. I can feel you trying to push back against me, but the restraints limit your movement.
