Calisa Warms Up Her Face and Performs Her First Blowing Tests (MP4 - 1080p)

Description: Calisa is very proud of her ability to hold the largest gags in her mouth, so as confident as she is that her cheeks can hold as much air as might possibly be needed for her work at the lab, she also knows the value of a good stretch prior to expanding.  once her face is warmed up, she proceeds to test her blowing pressure while also evaluating three different mouthpieces.  she really enjoys both the sensation of blowing with all her might, and the self-competition that makes her so exceptional at everything she does.  and that definitely includes blowing hard. while she produces above-average pressures with all three mouthpieces, which one provides better fit and comfort?
