We're not sure where Siri came from. Did she emerge, fully formed, from the head of some ancient god of arousal? Did the heavens bestow her upon us to make all our dirtiest fantasies come true? Is she actually just an ordinary human lady who happens to be crazy hot and amazingly good at sex? But we do know that, however she arrived, we hope she's planning on staying a good long time. Because after witnessing something this sexy, we don't think there's any way we can ever let it go.
