The whip struck you over and over. Penny scolded you the whole time "Bad ass puppy!" The worst part is that through all the pain and humiliation, the thing that hurt you the most is that you wanted to taste her ass again!
Again and again, the whip stripped your ass raw. The pain grew exponentially with each stroke, as it landed on redder, rawer, and more bruised skin every time. You were crying by the time you felt the prick of a needle in your left ass cheek, but you lost consciousness in a happy place, imagining yourself as Penny's ass puppy again, happily lapping at her asshole.
