This drives me crazy. What I do is wait till my parents go for their night out. I go to my mom's cabinet where she keeps the good stuff. Lately I've taken her astroglide lube, anal beads, 6' dildo, and her trusty vibrator. Then what I do is go to the front door and have it wide open. I make sure that I have my black thong and bra on.
It shows better on my white skin so people can see me better. I lie on the floor feeling myself up for a little and get my pussy all wet. Then I get up doogie style (all fours) with my ass sticking up in the air and lube my bumhole. Then slowly stick the anal beads up there( there 6 balls, 1' wide). They're perfect for me. Then I turn to the door so I'm facing the road and I start screwing my pussy with the dildo and vibrate my pussy. Just when I'm about cum, I get on all fours again without stopping on my pussy and pull my beads out of my ass. I have the biggest orgasm in the world-it never fails. I guess it's the excitement of maybe people seeing me (I think my women neighbour across the street has watched me (sees pretty good herself). But my beads never fail me either. Anyways, take care, and girls you have to try this-it's amazing.
