I listened to him speak in his half-shout toward the window and he still sounded controlled, though perhaps his voice was a slightly higher pitch than normal. I began to concentrate on what was before me, circling his cock with my fingers and pressing it up, out of the way, while my other hand slipped beneath his scrotum. I moved my hand against his balls, rolling them beneath the skin, testing the weight of them against my palm. I pulled them forward slightly, making a gentle ring around the top of his scrotum with my fingers, stroking slowly downward, not tugging, just gently stroking the soft skin. I felt his cock twitch in my hand, his balls jerk upward against my fingers. I simply continued to stroke downward, moving my touch between his testicles, feeling each of them independantly, rolling each of them against the skin. I could hear him trying to control his breathing and explaining to a customer that it was just very hot inside of the booth and that's why he was so flushed.
He started to draw back from the counter as the last customer left, but I heard another car approaching and another, and I laughed softly, knowing he could hear me in the close, warm air that pressed filled the booth like a tangible thing. I continued to stroke his scrotum with a feather touch as he waited for the customers to finish filling their cars and approach the booth, his cage in truth now, where he was pinned with a most dangerous sexual predator, it seemed. As the first customer came forward, I leaned forward as well, exchanging my tongue for my fingers, lapping across his balls while I pressed his cock up against his abdomen. I slid my other hand forward beneath his scrotum and between his legs, teasing the skin just behind his balls with two fingertips , pressing gently but firmly. I felt his knees quake and for the first time his hips jerked forward, but I simply continued to lick across his balls, taking them into my mouth, rolling them against my tongue. I moaned softly, letting the sound travel across my lips and tongue, through my cheeks, knowing he would feel every vibration.
The words he spoke started to sound short, sped up, as if he were eager to get each customer away as quickly as possible. But each one seemed to take longer, want more, ask for more. Until finally...one, a young female voice, asked for help pumping gas. I laughed softly as he fell silent, trembling, and looked at his cock, leaking precome steadily. Very gently, I slipped it back into his pants and rezipped him, but the bulge was huge, evident, like someone had slipped a foreign object into his trousers. I slid back into that concealed corner as he stepped away, casting me a glance that was mingled aggravation and lust, heading outside to help the customer. I heard soft chatter that continued a moment, then fell short, and I knew she had spotted his erection. I imagined her standing there, staring at the bulge as he worked to cover it while preparing the pump. In my mind she was young, nubile, large breasted and redheaded with a mouth that looked like it was made for sucking cock. I couldn't stop myself from slipping a hand down beneath my skirt as I pictured the scene, wondering at his embarrassment and if he would come back with an even harder cock.
In a matter of moments he returned and I smiled at him, thinking he must have worked very quickly indeed. He had left the girl to finish the pumping herself after he started her, and so I let him watch me rub myself as he stood near the door, my fingers slipping in and out beneath the black silk of my panties, glossy with moisture. I slipped the fabric to the side, spreading the lips of my pussy, sliding my fingers in and out, slick and fast while he watched, his breath coming fast, his hand in his pocket, of all places. There was a knock at the window, but he didn't look up, and I continued to tease myself. Another knock and a call, but he only blinked, not noticing until the woman banged again, sounding irritated as she yelled this time, and he tore his gaze away, moving to take her money. I remained quietly in the corner, my legs sprawled out, languidly fucking myself with my fingers.
The rushed stopped for now, he quickly moved over to the counter, his gaze riveted on me again. I watched his eyes flick back and forth between my face and my hand, and so I let my head tip back as I gasped and moaned my pleasure, eyes falling closed. I leaned back against the wall, drawing one leg up, spreading myself further, stroking my hard clit, my free hand coming up to cup my breasts through the fabric. I cried out softly, rocking my hips against the touch, and my eyes opened slightly to see him rubbing himself furtively through his pocket, unable to take his cock out because I was occupying his little "stealth" corner. I dropped my chin down, leveling my gaze at him as I continued to pleasure myself.
"I'm going to come...but don't you dare. I have other plans for you. Keep your hand off of the head of that luscious cock, too," I managed to gasp out the words just before my orgasm overtook me. I tried to keep my cries of pleasure quiet, but I felt glad that no more customers had driven up as I gasped and moaned, my body shivering beneath my own touch. He stared at me and I heard a soft, pleading moan as he stroked his shaft, and I knew he wanted so badly to come, to rub the head of his cock. I also knew his boxers would be damp with precome, probably soaked through, and I loved the idea.
I relaxed back against the wall, enjoying the lovely come down from my own orgasm, enjoying the soft sounds of his inarticulate pleading. I looked up, meeting his gaze, desperate and hungry, and slowly licked and sucked each one of my fingers clean, savoring the soft, sweet taste of my own body. When I was done, I smiled slowly at him.
"Now...go stand at the window again and don't move. I want you to be able to help customers while I play with you. After all...I wouldn't want you to lose your job simply because you weren't being attentive enough."
He gave me a long, searching look and then rose, moving to stand in front of the window again, watching for customers. As I slid back in front of him, my eyes resting on the bulging crotch of his pants, I sincerely hoped we'd get a few more people through, because watching him try so hard to act normally was just too entertaining.
As he stood there, watching the lot with trepidation, I again worked his fly open and freed his cock and balls, exposing them to my sight and touch again. He trembled and arched forward, able to give in to that urge since he wasn't under customer scrutiny, and it caused me to chuckle darkly. He moaned at the sound of my laughter, a pleading tone.
"Spread your legs slightly, darling...just slightly," I leaned forward and whispered the words against his cock and he almost yelped at the sudden touch, unable to prepare for it since I was out of sight. I slipped my hand down between his legs again, gently beginning to tease his ass with my fingertips, still slick from my slow licking of them. I used my free hand to press his cock up against his abdomen again, my palm rubbing against the underside of the shaft, thumb pressing into the frenulum. He gripped the edge of the counter, as if hanging on for dear life, tipping his head back to groan in frustration and pleasure. Then I heard the now familiar sound of rolling tires as another car pulled up, the clunk of the door as the driver got out to pump gas. With some difficulty, he got himself back under control, staring straight ahead, but I could hear soft little whimpers from behind sealed lips.
I decided to up the ante a bit as he dealt with the customer, and leaned in to press my lips to the base of his cock as I palmed his balls, my fingertips toying with his ass. I opened my mouth there, gently sucking on the skin, even nipping very gently. He gasped, open mouthed, and then quickly responded to the man approaching the glass. His tone sounded curt, clipped with irritation, and I wondered if the man was offended. My mind didn't dwell long on the thought, though, as I began to move my lips slowly up his cock, my lips parting against his skin so that I could snake my tongue out to follow their path with languorous licks. My free hand slipped around his cock, thumb and middle finger circling around the base and letting his cock drop forward, standing straight out like it normally did. I smiled to myself, listening to him try to engage in normal conversation while I toyed with him, my lips so close to his rigid cock, watching it drip with precome.
I felt him thrust forward as I released his cock to begin unbuttoning my blouse, moving into the air, seeking the touch of my hand, my mouth, anything that would satisfy that aching need in his balls. But he found nothing, and I heard him whimper softly, too softly to carry to the man on the other side of the glass. As he finished the transaction he grew very still, waiting...possibly dreading and yet longing for what would come next. I didn't intend to disappoint him. Once my shirt was open, I leaned in to claim his cock again, hearing a soft cry from him, I assumed out of the relief that his aching cock was in contact with my body. I know he expected me to take him in my mouth, but instead I leaned in and carefully slid the head of his cock along my breasts, rubbing the slickness of his precome between them. I pressed my breasts around him, then, sliding his cock into my cleavage, cupping my hand beneath his balls. That was all the encouragement he needed to begin begin slowly fucking the soft skin beneath his cock, the pace increasing as I didn't make any move to stop him, as I whispered soft encouragement clearly heard in the tiny booth.
I watched his hips moving, his cock pumping forward between my breasts, each movement delivering stimulation to the head of his cock that I had forbidden him to touch. I watched him tremble, growing harder, almost impossibly large, and I could feel his balls drawing up away from my hand. I knew he was ready to come...but I wasn't ready to let him. Thankfully, I heard yet another car pull in and he had to stop jerking his hips forward lest he be seen fucking the seemingly empty countertop. As he watched the newest arrival go about the gassing of their car, I slipped away from him, sliding his cock out from between my breasts. He gasped as, again, his cock was left hard, bereft, touching nothing to give him any relief at all.
