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 12 Feb 2026 10:16:05 +0200 https://pornfaze.com/videos/7633532/alexis-stretches-her-face-and-tests-her-blowing-pressure-mp4-720p/ https://pornfaze.com/videos/7053150/jasper-stretches-her-face-and-tests-her-blowing-pressure-mp4-720p/
Jasper gives her face a good stretch and massage, and then gets down to blowing as hard as she can. ]]> Mon 24 Feb 2025 08:09:54 +0200 https://pornfaze.com/videos/7053150/jasper-stretches-her-face-and-tests-her-blowing-pressure-mp4-720p/ https://pornfaze.com/videos/7631397/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.  ]]> Mon 02 Dec 2024 06:24:39 +0200 https://pornfaze.com/videos/7442970/mia-and-rae-stretch-out-their-faces-and-test-their-blowing-pressure-mp4-720p/ https://pornfaze.com/videos/7440938/mia-and-rae-stretch-out-their-faces-and-test-their-blowing-pressure-mp4-1080p/

At 6 foot 6 inches, blondi is our tallest researcher yet.  naturally, everyone wants to know her lung capacity!  she also warms up her face and tests her blowing pressure. ]]> Tue 12 Nov 2024 05:52:34 +0200 https://pornfaze.com/videos/7281188/blondi-performs-her-blowing-tests-mp4-720p/ https://pornfaze.com/videos/7276737/blondi-performs-her-blowing-tests-mp4-1080p/

Jasmin tries out a new lung training tool that combines a "calibrated balloon" claimed to provide a 1/2 psi load (actually closer to 1/4 psi), with three bypass holes to allow six levels of airflow through the simulated musical instrument. ]]> Thu 03 Oct 2024 07:30:25 +0200 https://pornfaze.com/videos/6773148/jasmin-tries-out-the-new-lung-trainer-mp4-720p/ https://pornfaze.com/videos/6767832/jasmin-tries-out-the-new-lung-trainer-mp4-1080p/
