You need to

"Mmmph" You whimper a little, hips rolling as you stare at Mr Longstreet. Your pussy needs his touch. Your dripping folds ache, **** for him to manhandle them. You don't care that there are people nearby. You don't care that you're married. You don't care about anything except you lusty need. There was never any doubt that you'd give in.

"Please...please, please! I want more. I need you." You whimper pathetically and look up at the tall, black man sitting beside you.
"Hmmm...you want more?" You nod eagerly. "Tell me exactly what you want me to do. And what you're willing to do for it."
You gape for a moment, struggling to find the right words. "I want...I want your fingers inside me. I want to feel your hand on me and inside me. I'll be a good girl. I'll...I'll...I'll do anything. Please, just touch me."
"Hehehe. You want my fingers in your cheating, married pussy?" Again you nod. "Then say it."
"Please Mr Longstreet. I...I want...I want your fingers inside my cheating married pussy!" The last words come out in a breathless rush.

Mr Longstreet wastes no more time. He leans forward, turning side on to face you. One hand goes around your shoulders while the other shoots down between your legs. You spread your thighs for him as he presses his palm against your mound. And then, with no slow build, he simply shoves one of his fingers into your dripping pussy. Your back arches as you tense and your head rolls back. "Ooooooh! Yes!" Your hands clench into little fists as a wall of pleasure slams through you.

The powerful man gives you no opportunity to adjust. Instead, his finger begins slipping in and out of your dripping snatch. Even his finger is big, stretching the entrance to your tight love hole. He curls his finger inside you, finding that right spot. Your mouth opens in a silent scream and you convulse, tight against him, your body rigid. You can hear him chuckling as you ride his hand, hips grinding down, desperately. "Good girl, good girl" You hear him croon to you as he keeps working his finger inside you.

You are lost, riding a wave of pleasure. For how long, you don't know before you collapse back against the bench, gasping for air. Your body spasms and you mewl as Mr Longstreet slowly slides his finger, now wet and slick with your juices from between your pussy lips. You gaze up at him, blankly as he shifts a little. Bright flashes momentarily blind you, but you don't really care about what they were. You're too lost in the golden haze of having been brought to such an amazing orgasm. In your current state, you've even managed to forget where you are.
