Cuộc đấu tranh nô lệ bằng dây thừng với kết thúc bằng quần lót đi tiểu

I had just come in from the street and really needed to pee… my Owner suggested a challenge… tying me up so I could (or couldn't) get free in time to pee… he only said at the end that there would be tickling too, which made things much more difficult (interesting) for both of us…
