The perfect pillows

Before spanking her you stopped and pondered " what would happen if I spanked multiple times, would it multiple the size of the growth, would spanking harder do the same, what's the limit to how big it'll get, how are those leggings holding together" after a minute of pondering your were interrupted because of a from a comment from the ghetto booty mistress right in front of you. "Aww come on don't leave a girl hanging," she said in a teasing voice, then she bent over straining her legging making her panties visible to you and shaking her money maker "It won't get bigger with you staring at it. Don't you want more tush to push". You not wanting to disappoint you happy accommodate her with a big ol smack to her rear for it jiggle and wobble and of course grow to a perfect 3 feet wide ass. With the new size came a new sound, one you've been hoping for, the sound of fabric tearing. Once hear you look down to see the leggings split down the middle of the leggings revealing not only her magnificent ass but her underwear which is slowing but surely turning into a thong. "Look at this, I could definitely crush something with this," she said gleefully hopping like a child, "Shame about the pants, but hey not everything can last *pushes her plump posterior against your crotch* but I don't hear you complaining."
