El desafío de seis litros de Fiona remasterizado parte 2

This one starts off with Fiona holding a brutal 3 liters of water and 1200ml of air. She leaks as I continue to fill her, but manages to hold the bulk of her air and water enema. The desperation you can hear in her count of the volume, and her continual moaning, is delightful. She's soaked her black panties right through and we get some amazing leaking and reaction shots in slow motion while she desperately tries to finish the challenge.
