For the woman who doesn't have a partner or just really enjoys having sex on all fours, check your mailbox for the Post Master.
This unique-looking toy features an assembly which holds a favorite vibrator/dildo at whatever chosen height or angle. The metal base is cushioned with a thick foam pad to protect the user's knees as they thrust back and forth on this "special delivery."
It does take some adjustment to get the vibrator into the correct position, but once there it provides a unique masturbation experience. On top of all that, it comes apart for easy storage under the bed. Or it makes a great conversation piece if left on display, as I found out when I forgot to put it away and the phone repair man noticed it in my living room!
