When we got our Pure Wand - many moons ago. I gave it to her and told her to figure it out and to teach me - and that worked out really well. However because variety is nice, I use some other techniques including;
Sliding the shaft along her vulva and clit as I keep the ball pressed up against the anterior portion of her vagina
Thrusting the ball along the anterior vagina to reach both her g-spot and deeper a-spot (careful with the cervix on this one). Typically her vagina elongates with arousal - so penetration distance increases
Drawing the ball up to the g-spot - then letting gravity pull it back down to the back/bottom - then repeat.
Occasionally I'll move the ball from side-to-side along the g-spot
Have fun! Doing things like this - is what makes sex fun. For us it's become more like recreation.We laugh and joke a lot about what doesn't work - but then when something does work - the fireworks explode!
