Pull it out

You pull the tip from your mouth and stroke the big dick for her climax as you continue to fondle her balls with your other hand.

"I understand honey, its a little intimidating your first time." she smiles down at you as you work the cock for her cum. " Don't stop baby you're so good with your hands, I love it when you work the tip."

Inspired by her words, every couple strokes you keep your hand at the tip polishing it in orbiting motions before sliding it back down.

"I'm so close baby, AH, I'm gonna cum!" she exclaims loudly as she throws her head back both her hands each fondling her big soft tits as she adds another element to her pleasure. "I'm CUMMING!" she shouts and in that moment you feel her cock grow rock hard as you begin to stroke her from base to tip gripping the cock tightly and her balls seize up almost entirely out of your other hand.
