Long enough to tease, not long enough to cum

After about fifteen minutes, Ashley is so aroused she is practically grinding on Sean's face. Her pussy is practically drooling onto her bed, and she is **** to cum. Her step-brother's tongue is experienced enough with a pussy to know when she is about to cum, and back off. His hands know just when to hold her hips down, and keep her from bucking against him, and fucking his face more.

Then, just when she is settled down, and backed away from the edge, he slowly works her back up to it again, and again. The cycle seems never ending. After nearly thirty minutes of this she's sobbing with need, begging to cum, having never felt this much pleasure in all her life.

Sean backs her off again and wipes her juices off on his arm, the sweet taste still on his lips as he backs away, "Mmmm....Ash, that was delicious." He sits back in the chair, and smiles up at her smugly, with a mischeivious wink.

Ashley looks up at him through lust-crazed eyes and asks him, "Wha-what are you doing...I need to cum?!" She's not touching her pussy anymore, not really sure she could make herself feel as good as Sean did anyways. "I need you to make me cum Sean...please!"

Her moans and begging was turning him on immensely, and his cock jumped in his shorts, "OK Ashley. I'l make you cum, but I want to put my cock inside you for a bit...just the tip." She nodded OK and said, "Sure, whatever just...wait, what?" What had she just agreed to? Did she just agree to let her step-brother put the tip of his cock inside her?

God she was horny though...she didn't know what to do.
