Ditria wants to examine a commercial "lung trainer" which consists of a strange cylindrical mouthpiece, a tube with three "bypass holes" that can be covered by the user's fingers, and a balloon.  once she gets the hang of this control specimen, she tries our improved version, with a much better mouthpiece, and our standard quick-connect fitting that allows different balloons or other pressure loads to be substituted. ]]> Thu 09 Apr 2026 22:00:21 +0200 https://pornito.xxx/videos/7159251/ditria-tries-out-a-prototype-lung-exerciser-mp4-720p/ https://pornito.xxx/videos/7155207/ditria-tries-out-a-prototype-lung-exerciser-mp4-1080p/

Ditria is new to the lab, and knows her face needs a good stretch to survive the sort of blowing workout she anticipates.  she also is curious which mouthpiece will allow her to blow most effectively, ideally, without having to remove any of her lip piercing jewelry. ]]> Tue 30 Dec 2025 13:51:38 +0200 https://pornito.xxx/videos/7021804/ditria-stretches-her-face-and-tests-her-blowing-pressure-mp4-720p/ https://pornito.xxx/videos/7016975/ditria-stretches-her-face-and-tests-her-blowing-pressure-mp4-1080p/

Sydney begins by using a commercial "lung trainer" that consists of a strange cylindrical mouthpiece, a tube with three "bypass holes" that can be covered by the user's fingers, and a balloon.  once she gets the hang of this control specimen, she tries our improved version, with a much better mouthpiece, and our standard quick-connect fitting that allows different balloons or other pressure loads to be substituted. ]]> Sun 09 Nov 2025 17:16:57 +0200 https://pornito.xxx/videos/6939277/sydney-tries-out-a-prototype-lung-exerciser-mp4-720p/ https://pornito.xxx/videos/6933495/sydney-tries-out-a-prototype-lung-exerciser-mp4-1080p/

Alexis stretches and puffs her cheeks to get them as relaxed as possible, and then tries three different mouthpieces for comfort and seal quality, while measuring her maximum blowing pressure. ]]> Thu 07 Aug 2025 13:01:18 +0200 https://pornito.xxx/videos/6814737/alexis-stretches-her-face-and-tests-her-blowing-pressure-mp4-720p/ https://pornito.xxx/videos/6811177/alexis-stretches-her-face-and-tests-her-blowing-pressure-mp4-1080p/

Mia is helping rae to become acclimated to the lab, and that starts with seeing how hard she can blow.  to minimize her discomfort, they began a routine of stretching and relaxing their faces, so that their cheeks can puff to the limit while blowing with all their might.  ]]> Fri 02 May 2025 11:29:09 +0200 https://pornito.xxx/videos/6667583/mia-and-rae-stretch-out-their-faces-and-test-their-blowing-pressure-mp4-720p/ https://pornito.xxx/videos/6664438/mia-and-rae-stretch-out-their-faces-and-test-their-blowing-pressure-mp4-1080p/
