Cross your legs and hope it doesn't enter.

Your arms were exhausted so you quickly cross your legs to cover your vagina and let go of the vibrator. The vibrator tries to go in your pussy but it can't get through your legs. Confused it goes around sometimes it pokes your butt and mouth but continues on. Eventually it gives up searching for your pleasure hole, flys up, and self destructs.

"well that was weird," you say really confused about the whole experience. You felt even more tired now..
"Time to get out of here.." you thought and headed to the door, after crossing through the door you left the front door gathered you clothes and went to a different house. You think you made the right choice, but felt like something could have been gained there. "Oh well probably not worth the risk.."
