Well, if you're playing together...

Have her lay back on the bed, so her head is hanging over the edge,
supported by her shoulders and the rest of her body weight.

You are standing with your erection near her face so she can lick it and service you while you lean forward and tease her with the toy.
-- Follow Lord Chuck's intructions to drive her nuts.

If you fill her mouth, let her hold you around your thighs
and pay attention to her sounds, smack and squeezes.
She might be excited, she might need air, perhaps a bit of both.

If you want to send her "over the edge" - use the toy in one hand,
inserting and rub her clit with your other hand.

Playing with her sensitive breasts, however you do that she likes,
while your moving the toy inside of her or on her clit should also
do the trick.

As with the other warnings, the vibrators are fun, but they
are not bendable or as soft and comfortable as your hard body.
Remember the song about "I love a man with slow hands..."
Yes, slow is good to get started.

Speaking from experience, the tendency to go harder and faster as she gets
more excited is natural, but remember, it's not your finger or your cock inside of her, it's an unyeilding toy. So...yes, sing that goofy song if you have to...

And for some of us, their is such a thing as requiring a break
between intense climaxes. Espcially with those G-spot toys!

Have fun,

Ruby
