Unbutton her shirt

Well, as long as she's taking things at her own pace, maybe you can turn up the heat in another way.

Barely able to think for all your desire, you reach downward, running your hands down the bare length of her neck, forward across her collarbones, and to the top button of her blouse. You fumble for a moment, then swiftly undo it.

She pauses for a moment, looking up at you, then smiles and returns to her quick licks, this time pressing her lips a little more sensually against your cockhead.

You unbutton another button, then another, and another. You can see the curve of her inner breast now on the right side, and somehow the more you undress her, the hungrier she seems to get. She hasn't quite taken you into mouth, but her lips and tongue feel like they are pulling at you with every stroke. You try to push into her mouth but she still moves away, returning to lick you vigorously when you withdraw.

You're almost out of your mind now, you want to come so badly! You slide your hand under her shirt, taking her small breast fully into your hand, feel the hard nub of her nipple. She moans quickly, almost squeak but then stretching out into a deeper sigh.

As you close your thumb and forefinger around her nipple in a gentle pinch she moans again, and this time she finally takes you fully into her mouth, rolling her tongue against the head of your cock as she lets you deeper and deeper inside.

You give one more thrust and then gasp as the orgasm hits you in an instant. You start blasting into her mouth as she sucks you.

She pulls back, startled, and a couple white gouts hit her in the face. Diana quickly reassures her.

"It's ok," your friend says to her student, "Keep going, finish him off!"

Sophia nods and dives back, and somehow the renewed attention from her soft tongue gives your orgasm a second wind, five, six, so many rapid-fire pulses of blinding pleasure as she works up and down your shaft, as you release into her mouth.

Finally, you're done. You stand there catching your breath as Sophia comes up for air, her face still smeared with two lines of your cum, and her lips dripping with it as well. She seems fascinated, satisfied, and has an excited glint in her eye.

Diana quickly reaches out with a tissue, and wipes off Sophia's face. "Good job," she says, "I know you were nervous at first, but you tried something new, and you did really well!"

Sophia looks up at you, the glint in her eye even stronger.

"When do I get to try again?"

The End.
