Lana has been tasked with investigating a concern about the "cracking pressure" of a spring-loaded check valve.  she compares it to one of the larger swing-gate-style values we have been using, which has essentially no cracking pressure, but can sometimes not close when pressure is too low.  she chooses some clear qualatex 350's for the task, and really enjoys seeing how long she can make them inflate.  so much so, she may have forgotten the purpose of the experiment.  but that's ok with us.  ]]> Tue 26 Nov 2024 12:44:52 +0200 https://pornmeka.com/videos/805103/lana-compares-two-check-valves-using-some-long-entertainer-balloons-mp4-720p/ https://pornmeka.com/videos/804568/lana-compares-two-check-valves-using-some-long-entertainer-balloons-mp4-1080p/

Mia and rae try out a pair of q646 airship balloons.  each has to learn how to manage the back-pressure without a check valve, but they eventually get them both blown up.  then they move on to the smaller but harder q350, using check valves and puffing with all their might. ]]> Fri 29 Mar 2024 16:34:20 +0200 https://pornmeka.com/videos/466516/mia-and-rae-exercise-their-lungs-with-some-airship-balloons-mp4-720p/ https://pornmeka.com/videos/465595/mia-and-rae-exercise-their-lungs-with-some-airship-balloons-mp4-1080p/
