She is. Your face is her fuck toy.

As you slide the tip of your tongue down lower, hunting the soft, telltale folds beneath the thin fabric, Sam's hand slides from on top of your head to behind it, gripping the short hair at the back.

"Okay, baby, time for that blowjob you promised!"

As she pushes you from the base of your skull, she starts to grind her hips into your face. Now, if you had wanted to get free, you're not sure you'd be able to. Of course, right now, you're not trying all that hard...

With some difficulty, you manage to slip your tongue around the side of her panties, pushing the cotton material aside, despite the growing intensity of her movements. As your tongue finally finds the soft, damp flesh it seeks, Sam squeals, "Ooh, yes! Yes, Paul, blow me, baby!"

She humps your face harder and faster. Between her pounding crotch and the tight grip of her hand behind your head, between the metal teeth of her zipper and the awkward twisting of your tongue pushing aside her underwear, you are starting to wear out. She keeps on going, though.

Finally, she begins to climax. "Yes! Yes! Yes!" Somehow, you manage to keep your tongue working up and down her lips, regularly visiting the uncovered nub of her clitoris, while neither hurting yourself nor letting your tongue slip out of her fly. The smell of denim and womanhood overpower you as her iron grip keeps your face clamped tight against the front of her pants. If it weren't for her hand at the back of your head, you would have been bucked free by now.

With her other hand massaging a nipple through her uncovered bra, Sam finally explodes in passion and pleasure. "Oh, Paul!!"

As her legs tremble with the passing aftershocks of her orgasm, the grip behind your head loosens, but only slightly at first. Her other hand comes down from her large breast to fondle the side of your head and caress your cheek as you continue to lap slowly at the entrance to her vagina. Finally, gently, she pushes your head back away from her crotch.
