Stacks of Pillows
In my opinion, a stack of pillows is an absolute must. *Nothing*--not carrots or faucets or oral sex or "the deed" in any position--gives me a more intense orgasm than thrusting against a firm stack of pillows.
Pillows are great because it's easier to imagine that someone is beneath you, and because they're perfectly legitimate, everyday objects! Nothing to hide in the back of your top drawer, nothing to be embarrassed about purchasing. The only thing you have to do is wash them every once in a while.
Anyway, here's how it works. I am fairly short (5-2) and find that 2 regular pillows is ideal. Just one is too low, and three restricts movement. I place the stack lengthwise on my bed and straddle it, wearing just underwear (though if it's daytime and I'm in a hurry, clothes are OK). Sometimes I lean forward, bracing myself with my arms, and other times I sit up straight. Either way, I start thrusting, sliding my whole genital area across the pillows, gently at first then firmer and faster as I start to climax. My sliding strokes also become shorter. You can rock front to back or back to front, either way. Try changing directions for a surprise. Anyway, lower-back flexibility and looseness through the hip area are necessary for effective movement.
I like to do this technique when I wake up in the morning. I can orgasm in under two minutes if I hit the right rhythm, or prolong the climax by sticking with very light strokes for as long as I want. A fun variation is to take a full-size bath towel and carefully roll it up lengthwise. Place it lengthwise over your stack of pillows, and tuck the ends of the towel under the pillows to hold it there. This gives a deeper stimulation, like you're dry-humping a man. I've heard of people humping pillows with an object in the vagina at the same time, but I'm not sure how that would work. Have fun! --Trish
