We love this bizarre inflatable dildo! Use a little lube to slip the flaccid cock in your bum hole, then gently pump the handle and let the big black boy swell inside you.
The gorgeous ribbed details on the shaft will hold it firmly in place as the dildo swells and swells — leaving you very full and very turned on. If you fancy an extra thrill, let your trusted partner do the pumping whilst you're tussled up in bondage. If the pressure all gets too much, twist the quick release air valve and you'll get a little relief from your sticky situation.
Ingenious and thoroughly recommended!
