The Horseless Rider is a solo sex position the targets the vulva. It's especially good for those who enjoy broad stimulation in the crotch. People with very sensitive clitorises who don't like the feel of direct contact targeted at their clit will like the feeling of this position.
All you need for this position is a pillow and a Satisfyer Sexy Secret panty vibe. Slip the vibrator into your underwear and secure it with the magnetic clip. Then, bunch the pillow up to make a ridge and position a leg on either side. In your straddling position, you can rub your vulva against the mound of the pillow, allowing the Sexy Secret to work its vibrating magic as you grind at the speed that does it best for you. Experiment with slow sexy figure eights with your hips, or hard and fast thrusts. There are plenty of patterns to try out with the panty vibe for even more variation.
