Let her pull you out and play with you at her own pace

You decide to let her take her time and explore you on her own. After rubbing you through your boxers for a couple minutes, she musters the courage to reach inside. Her eyes widen when she grabs your thickness, and she pulls you up straight so that you poke out of the waistband. "Wow," she says. "You're really hard." She softly jerks you inside your underwear, and after awhile she bends down and hesitantly licks your cockhead. You groan encouragingly, and she licks and sucks at the tip that sticks out. She reaches down further and feels your balls, blindly groping and squeezing them.

Eventually, she gets impatient and strips your boxers off, then licks her palms and starts jerking you off. She looks at your face questioningly, and you smile and nod. She grins back, apparently feeling like she's succeeded, and bends down to lick your cockhead again while she jerks you. It takes awhile, but eventually her gentle ministrations bring you to the edge.
