まだいっぱいかどうかはどうやってわかりますか、パート4

I’ve pulled the Coloclean out of LRO’s ass and left the vibrator strapped to her leg while I clean up her spilled water. Next, it’s time for a belly rub before I let her go, put her across my knee and carry on filling her with the syringe. Finally, when I think she’s full, I put her on the slave toilet and let her release.
