You need to show her what a man can do

You give her wet pussy a last lap and wipe your mouth before smiling at her gasping face. Her chest is heaving, her small tits wobbling as she pants.

"Oh My! Mr. Sharp! I...I...I've never...climaxed...like that! So incredible! Oh My! I'm still shaking!"

"Glad you liked it Emily," you smile, stroking her wet folds with two fingers. "But you know this doesn't prove whether you like girls or boys better."

"But you...you were so much better...I mean I've never been...with a girl...I mean with her licking me...but that was so good...Oh My! So very good!"

"There's only one sure way to tell which you prefer," you smile, reaching for your zipper and pulling it down. "Only one way."

"Oh My! Mr. Sharp! I...I...don't know..."

"Only one way," you repeat, pulling your stiff cock out and stroking it slowly. She bites her lower lip and looks at you, her eyes timid as they gaze at your thick hard shaft. You rub it slowly between her sodden lips, watching her whine as you tease her with it.

"Oh My Mr. Sharp, Oh, I...I'm not sure..."

"Only one way," you say softly, starting to ease your meat into her wet hole. She stares at you, her eyes getting even wider, her hands holding her breasts as she waits to be impaled.

"Oh...Mr. Sharp! You're in me! Inside me! Oh My! You're in me!" she whimpers with excitement, arching her back as her eyes grow needy and desperate. You ease another inch into her tight wetness and she moans softly, stroking her body as she presses her lips together with a whine.

"Only one way Emily," you say with a smile, sliding further into her. "Only one way."

"You're in me! In me! In me! In me! In me!" she wails as you slowly fill her, her body starting to quiver as she locks her legs behind you, grinding herself on your cock as she helps you impale her. "Oh My! Oh My! Inside Me! Oh My! Oh My! Inside Me!" she squeals as she comes with shuddering spasms.

Grinning, you grab her hips, lifting her ass off the desk and starting to pound your cock into her trembling body, slamming her fiercely as she wails and bucks with orgasmic bliss. You're grunting fiercely, loving the feel of her tight young cunt gripping and milking your thrusting shaft until you explode balls deep inside her, filling her with hot seed, flooding her with your essence.
