Use your fingers.

You put one hand on her stomach and slide it downward, to the patch of hair at her crotch. She moves her feet farther apart, allowing you to reach down between her thighs and find her wetness with your fingers. She exhales a slow, satisfied breath.

You toy with her, swirling your tongue around the nipple of her breast, drawing your fingers back and forth across her clit. Her body shifts under your hands and under your mouth. Her back arches, her hips sway, her toes dig into the carpet. She clutches your head to her chest, leaning on you for support.

She is quiet; so quiet you wonder if you?re not arousing her. But then her grip on your head tightens, and she begins to make little sounds. ?Ah ... oh ... oh ... uh ...?

This is enough to convince you that you are on the right track, so you keep stroking her pussy, keeping your rhythm steady. She pushes her hips against your hand. Her fingers clutch your hair. And just as you think she might be getting ready to erupt, she whispers, ?Now. Get in me now.?
