I love my pillow under my ass when I have sex.
Well I just tried it while I was using my vib and I had so many g-spot orgasms I passed out...I woke up about 2 hours after and cleaned up my vib and me and went back to bed. So this is what you do:
First, you want to make sure that you have a towel down first cause your gonna get stuff wet.
Second, put your pillow under the bottom part of your butt so you are kind of curling your bottom to your belly button (doing a reverse crunch if you were excercising...making a C). Keep your legs relaxed in the bent position or raise them up for deeper penitration with the vib.
Time to start...
I play with my clit first (with my fingers or a vib bullet or smaller vib) to get me nice and wet and then when my pussy is aching for more I put my longer and thicker vib in.
Hold it in at first and just rock it back and forth all the while holding that reverse crunch. You will feel like you have to pee..THAT IS WHEN YOU KNOW YOU ARE DOING IT RIGHT..YOU DON'T HAVE TO PEE YOU ARE GOING TO CUM SO HARD YOU WILL HAVE TO CLOSE YOUR EYES..JUST DON'T STOP THE ROCKING IN AND OUT.... You will have mind bending orgasms one right after the other. You may want to start pounding your pussy with the vib, pushing the base towards the pillow to angle the head of the vib at the g-spot. More orgasms will follow!!!
If you pass out it is ok cause the vib will slip out...You may have to buy another set of batteries. But it is all good, I know this!!!
