Sienna makes her Bound2Burst debut. She has not been to the bathroom in six hours and has been feeling the urge to empty her bladder for the last four. As she chats to us and tells us about desperation incidents that have occurred in her life, she is truly bursting for relief. She wiggles her legs to help her wait a little longer, but we can tell as she chats that she is badly distracted and getting very close to losing control and wetting her panties. When she does finally let it go, she stands with legs apart and dress raised, and lets it stream through her panties. As her muscles relax, the initial trickle turns into a torrent which clearly shows how much she had been holding.
