Sometimes you just want to test a girl's tolerance. Some girls also desire to test the limits of the machines. Like thus, Kaylee continually giving while the machines continue to take.
The Fucksall and The Satisfyher begin with an airtight double penetration fucking, and two machines are used in every scene until Kaylee's blonde hair is thrown around her head in the greatest post-sex hairdo you've ever seen. Until she expresses shock at what is happening to her own pussy, we fuck her.
