Dear marie
First off I would recommend sex with hondo but in cases where that is not possible I have the perfect solution for you!!

This isn’t just a USB vibrator. This one includes 5 interchangable latex probes (wow!), has 10 unique preset pulse/vibrate rhythms (yihah!), and features a self adjustable finger ring vibrating bullet (amazing!).
I am also working on a squirrel powered vibrator just for you!!
Hondo (damn I missed my true calling)
