The effect was one last lump in her diaper, and a massive orgasm. Trish lost her balance and dropped onto her butt, causing the mess to spread out over her bum, but she didn’t notice. After several seconds she looked up at Sally and smiled for effect, then slowly stood up. The diaper was now so think she couldn’t get her knees together. The large mess now felt disgusting against her fanny.
She toddled towards Sally and wrapped her arms around her back and kissed her again. “Thank you mommy, can you change me out here, please?”
Sally looked flustered for the first time. “But everything is in the back.”
Trish grabbed Sally’s hand and placed it on her diaper, “Then go get it, I’ll wait.”
