Opening my mouth, I cover her pussy with my lips, gently rubbing the area below her clit with my tongue. Her hand presses my head down against her harder, and that is one way I know what she needs. The other way is her breathing, which is coming in ragged gasps now.
Her g-spot fascinates me. When we first started playing this way, it was a barely perceptible hardening that would happen before she came. But each time we did it, it seemed like it would swell larger each time as if it were a muscle that was being toned up with exercise.
She is wet enough now that the towel under her ass is getting wet, and my entire hand is slick with her juices. She groans lowly, kicks the left leg up over the seat back, lifts her right foot up on the dashboard, toes pressed into the glass of the window, and spreads her legs as wide as they can go.
I know this moment, it's when she wants to be fucked hard, is just focusing on the feeling of being filled up deeply as possible. I am tempted to slip my cock in her along with my fingers (that drives her crazy) but instead I put in a third finger, then my pinky too, so now I have four fingers inside her.
She clenches the seat back with one hand, and the other is pushing hard against the back of my head. My face is pressed so hard onto her pussy that I barely have room to breathe. Words are lost to her now; animal grunts take the place of the words I know she would be saying. That's OK, because my body knows what her body is crying for.
I push deep with my hand, rubbing the swollen spot inside her that now feels about the size of a baseball and is rock hard. As my knuckles are straining against the tightness of her entrance, not quite daring to push harder for fear of hurting her, I can tell by her moans that she wants that fullness.
"UuuUGGHHnnn..." She suddenly thrusts hard with her hips, and my hand pops inside her, leaving only my thumb outside. I started rocking my hand, flats of my fingers now cupping her hard and swollen g-spot. Her moans get louder and louder, building in volume to nearly a scream. She presses my head down with crushing force and her hips thrusting madly, her body fucking my face, fucking my hands.
