this technique I have used for a while. One night I was on the phone with my bf and we were talking about making out. I was getting pretty hot. (I was using the cord type phone because the cordless battery was dead.) I turned once and the coiled cord rubbed across my nipple through my t-shirt. Oh, that got my attention. I did it a few more times and held the cord so it just flicked across my nipple. Later in bed I started thinking about this and wondered what it would do down there. I snuck out of bed in my panties and night shirt and went to the hall where the cord phone was. I was already feeling hot and moist down there. I straddled the cord and started moving it back and forth. OMG, that was nice. I kept the pressure light and it just tickled my lips and clit. Then I added more pressure and oh, I was quivering with an orgasm in no time.
I picked up a phone cord at the store and keep it in a junk drawer in my room with all kinds of other items. It really doesn't look out of place with the other stuff in case someone opens the drawer. When I opened the package, it had a plastic smell so I washed it well first. Now I can play with it anytime in my room. One of my favorites is to tie one end to my bed and hold the other end in front of me. I straddle it and then can sort of hump above it. I raise or lower the front to control how much pressure is there. mostly I do it with panties on because it is so strong on my bare pussy. Sometimes I do it naked though. I have put baby oil on myself in the back and then do it so it rubs my anus too. That is a different feeling that can get me hot also. hope this technique might be fun for other girls too.
