“Shit, were you speeding?” Cas asked, as his head snapped around quickly to look at the flashing lights of the SUV through the back window.
“No, I was trying not to draw attention. Everyone, be cool.” The worry in Todd’s voice was something neither Joey or Gwen had heard before. He always was so cool and collected, unbothered by most things. It made both their heartrates skyrocket, but none more so than Gwen.
“I still have this beer ... what should I do?” Gwen panicked, searching find a place to hide it.
“Fuck! Shit! He’s coming...” Cas said; he looked back and forth from the girl beside him to the approaching officer. He grabbed it from her hand, it was mostly empty; only a little bit remained.
Todd looked back and said hastily, “Stuff it under her skirt. Quick!”
“But-” Gwen tried to protest but Todd stopped her.
“-Shut up and hold it there. Cas...”
Cas quickly stuffed the cold aluminium can between Gwen’s legs, right up against her pussy. He smoothed over the top of the skirt so it couldn’t be seen before he sat back just as the officer ambled his way to the back of the truck. He looked in the bed, the boxes were generic enough, but he took more time than necessary. Eventually, he made his way up to the cab and looked through the windows till he got to the driver’s side.
“D’ you know why I pull’d you ov’r?” the man asked Todd in a southern-ish accent.
“No, sir officer...” Todd responded succinctly and politely.
“It’s Sheriff, boi!” The sheriff replied loudly. “It seems yo’ rea’ brake light is-s’out. License and registra’ion, son.”
Todd pulled out his wallet and handed the sheriff his information. The sheriff looked at the picture and then at Todd, nodded and turned to walk away ... but suddenly stopped. His head tilted up, his squat nose lifted in the air, like he was smelling something.
Gwen hoped he couldn’t smell the beer or see the booze in the back. She sat on her hands to keep them from shaking, trying not to draw attention to herself or them. Her parents knew they drank occasionally at parties, that wasn’t a big deal, but getting arrested transporting a large quantity of alcohol while underage was a different story. Worse still, what if this led to them finding out what she and Joey had been doing all summer; that would be a fate worse than prison.
She tried not to look directly at the sheriff as he looked through the rear windows of the truck cab. She again cursed herself for not wearing a shirt, still wearing her stupid and now increasingly gross bikini top. It had gotten dirty from the ground in the woods and from being on the sticky floor of that liquor store. With increasing fear, the sheriff walked back to Todd’s open window.
“Have y’all been drinkin’?” he asked, the twang in his voice was both funny and terrifying.
“No, sir,” said Todd confidently. It was true for three out of the four, at least.
The sheriff sniffed the air again, closer to the window.
“I got’s the nose o’ a bloodhound, boi. Don’t be lyin’ to me, now.”
“But sheriff, we’re underage and that would be wrong.” Todd’s voice was calm, maybe too calm; as it seemed to rouse the sheriff’s suspicions further. He looked around at the four faces in the vehicle, Joey and Gwen tried not to look in his direction.
The sheriff raised his voice, “All r’ght, boi. Outta the truck, I wanna talk to you.”
Reluctantly, Todd stepped out, shutting his door behind him, “You have no right to do this,” he said firmly.
“I wanna know what’s in the back, he’re.” The sheriff pointed to the boxes secured in the bed of the truck. The tension raised dramatically in the truck, even Cas seemed to be sweating.
Todd didn’t waver, “I don’t have to tell you, sir. It would be illegal search and seizure without a warrant.”
“You think you’s smart, boi? Get ov’r he’re...”
The three still seated in the truck watched from the rear window as Todd was led over to the front of the Sheriff’s green SUV and was suddenly thrown against the hood. He didn’t fight, he merely shouted about his rights. The sheriff kicked Todd’s legs apart to frisk him, before pulling him up with his hands behind his back and placing plastic ties on them.
“NAOW! SIT DOWN ov’r the’re!” The sheriff pointed to a patch of grass along the side of the road. Todd complied.
As the sheriff moved back toward the truck, Cas looked at both of the Tanners. “Don’t say anything! He can’t search shit, so keep your mouths shut, understand?”
“YOU! OUT!” The sheriff pointed to Cas. Cas obeyed and was led to the SUV where the process was repeated.
“Shit Joey, what are we supposed to do?” panic filled Gwen’s voice. She still frantically searched for a place to hide the can but couldn’t find one anywhere. The front seats had stuff jammed under them already and there didn’t seem to be a place to put the can in the back.
“He can’t do this.” Joey said nervously, watching Cas get frisked against the hood of the SUV.
“He’s doing it anyway, Joey. He’s some redneck hick sheriff, who’s going to stop him?”
“Shit shit shit, he’s coming back!”
He walked over to the passenger’s side and pointed to Joey next. Without any other idea, Joey did what he was told and got out, only he wasn’t led over to the SUV, he was pressed against the side of the truck.
“Do you got anythang’ sharp on you, son? Anythang to declare lik’ weapons’ or some such? Nothin’ you wanna tell me to make this easier on yo’self?”
“No sir.” Joey had never had any run-ins with the police in his life. He’d always believed they should be respected and if people followed the rules, there would be no need to worry. That philosophy was put to the test as he was roughly searched without probable cause before being placed in plastic cuffs and told to sit next to already detained Todd and Cas.
“You didn’t say anything, did you?” Todd asked quietly. Joey subtly shook his head no.
“Out he’re lil’ missy,” the sheriff opened Gwen’s door. She squeezed her thighs tightly together and did her best to exit the truck with the can lodged in place. She just had to hope he didn’t get too handsy since she was a girl; though she wouldn’t have put money on it.
Gwen stepped forward and held her thighs tight as best as she could. Each step was short as she turned around to place her hands on the side of the truck.
“You got anythang on you, missy? ‘Nothin’ sharp or dangerous?” he asked, his portly face close to hers. She hoped he couldn’t smell the beer on her breath.
“N-no, sir...” she replied nervously. She heard him sniff the air close to her. She tensed up.
“Nothin’ you wanna tell me, miss? I promise I’ll go easy on ya.” He moved even closer, she felt him press up against her, poking her ass with what she hoped was his gun.
“N-no, sir...” Gwen sputtered out. Her legs and body trembled nervously, but she kept her thighs tight.
He leaned in, “Alraight, if that’s how you wanna play...”
A pair of thick hands were placed on her shoulders and moved down slowly. They stayed on the outside of her arms, down past her elbows and finished at her hands. It was ridiculous since she wasn’t wearing anything but a bikini top, there obviously wasn’t anything to find on her bare skin. His hands moved inward, along the underside of her arms, moving closer and closer to her core. Every inch he touched brought more fear that she’d be found out. She didn’t know what he’d do when he reached her armpits; she’d been groped enough that it was fairly normal; but this was a man of the law.
Luckily for her, he only grazed the underside of her top, moving along below the edge of her tits. He stopped and checked between her tits with light pressure, but did not grope her. She almost breathed a sigh of relief until he moved down her trunk. His fingers touched every rib on the way down; and stopped at the waist of her skirt and ran along the top from back to front. This was it, the make-or-break moment.
Gwen closed her eyes and wished, as his hands cupped her ass, squeezing gently on her butt as he made his way lower. They moved down the outside of her legs, down over her knees and to her shoes. He paused, his face inches from her ass; she didn’t know if he could see up her short skirt.
“Open your legs up, missy. I’m sure you’ve heard that befor’...”
Gwen tried her best to do as she was told, and clenched tighter on the can that pressed into her flesh. She sensed him moving but couldn’t see what he was actually doing. Suddenly, she felt something hard and smooth against her left leg.
“I said, SPREAD’EM!” he barked, tapping her left knee with whatever was in his hand. Out of instinct, she moved and instantly regretted it. The clang of the can echoed out as it hit the ground between her feet. She knew they were busted.
“Whadda we have he’re?” the sheriff said gleefully, bending down behind her.
“Sir, I can explain...” Gwen tried to argue.
The sheriff chuckled, “Can you naow? Of cou’se you can ... love to know how this got between yo’ legs?”
Gwen slowly turned around, uncertain if she was going to be handcuffed, “Sir, it was just one drink and they didn’t kn...”
Her mouth fell silent as she turned to see the sheriff not hold up the beer can she dropped but a small little baggie with a strange white powder inside.
“I’m waitin’? How’d this get up there?” he asked with a smirk on his chubby face.
“I- I didn’t ... I don’t know what that is ... That isn’t mine...” Gwen’s panic grew. She quickly looked over to the three others seated on the grass; all of them looking with stunned silence at the baggie.
The sheriff tipped his hat, “Huh, it never is ... and yet, it came outta yo’ cooter. How else diddit get up there?”
Gwen had no words, even she couldn’t explain it. For all Todd and Cas’ faults, they weren’t drug users, as far as she was aware. They were bastards, manipulators, and blackmailers; but they didn’t seem to deal or use drugs like whatever that was.
“STAY THERE!” The sheriff yelled at Gwen. She wasn’t about to make a run for it; she was in enough trouble already. He looked at Todd and grinned wide, “Now, I got probable cause, boi.”
The sheriff made his way over to the back of the truck and opened the top of the boxes, pulling out the different bottles of alcohol and beer they’d just bought. He held a few up in his hands, a crooked smile on his face, looking at Todd and the others on the grass.
“I gotchu now, boi.” He gloated, placing the bottle back in the bed of the truck before he headed back over to Gwen. She was petrified about what would happen. It was no longer underage possession of booze; it was apparently drugs too.
“Alrigh’ missy, what else you got on ya?” he asked forcefully. He pressed his hands hard onto her back and she had a hard time keeping herself from falling over.
“Nothing, I swear. I don’t even know what or where that came from.” She was near tears. Her life was flashing before her eyes.
The sheriff leaned harder on her, “Now, I get’a fully check ya.”
“But what-” Gwen was about to ask what that meant but a tug on her bikini top told her everything she needed to know. She was about to be strip searched right there on the side of the road. At any moment, a car could drive by and see her; it was humiliating.
Her tits spilled free as the top was pulled away from her body. The sheriff inspected it, checking the cups and sides for any contraband. Once cleared, he moved his hands over her tits, roughly cupping and squeezing them. It wasn’t the respectful pat down she received earlier.
“Which one of d’em boys is your boyfrien’?” he asked, as his finger and thumb pinched her nipples, which made her wince.
“None ... do you have to pinch so hard?” Gwen whined, her eyes welling up.
“Girlie, I haven’ even begun. You had yo’r chance. Now I gotta check ya, since you be’n lyin’ to me. I ain’t gonna be nice now.” He gave her tits an extra hard pinch. “Now, who’s you boyfrien’? I know a slut like you is givin’ it up to one of ‘em.”
“Please Sheriff...” Gwen begged, “ ... one of them is my brother. The other two we only met a few weeks ago.”
“Doesn’t mean a druggie ‘hore like you, won’t be puttin’ out to one or all of ‘em.”
His hands mercifully left her tits, her nipples were stiff, but her breasts were sore. They moved down her sides again, only this time they didn’t go softly. When he reached her skirt, he spun her around and demanded she pull them off. His eyes lazily took in her chest, nipples hard and red, before she was ordered to lower just the skirt.
Red with embarrassment, tears running down her face, and her tits now hanging out for any driver to see, Gwen pushed her skirt down to the ground. All that remained of her dignity was a pink piece of material that covered her crotch; and she knew it likely wouldn’t stay on for much longer. The sheriff picked up the skirt and inspected that too, being so thorough Gwen could have sworn she saw him sniff it. When done and cleared, he tossed it to the ground.
“Tak’em off,” he said gruffly, his eyes moving from her tits to her pink-covered crotch.
“Shouldn’t a female officer search her?” Joey yelled out suddenly. It was something he’d seen on a TV show and hoped it would help Gwen from suffering the full humiliation.
“Quiet boi, you’re next!” He yelled in Joey’s direction. “I could take you to the station, process her possession and drivin’ alcohol ‘cross county lines. We do that, lil missy here’s gonna be sharin’ a cell with a bunch o’ drunks. Only got one cell in this here county jail...”
The sheriff leaned in really close, so close she could smell the coffee on his breath. “Won’t get in fron’ of the judge till mornin’ and my deputy has a habit of fallin’ asleep on duty ... wanna bunch a drunks all over ya?” he smirked. “ ... maybe ya do ... or you can show me what’s what now...”
With no other option in sight, Gwen reluctantly reached for the sides of her bottoms and pulled them down. She saw the sheriff’s beady eyes watching her as her pubic hair came into view, and he licked his chapped lips when her bottoms hit the dirt at her feet. With all dignity gone, she kicked them in his direction.
He gave her a smile that grossed her out as he bent over to pick up her bikini bottoms. He checked them thoroughly ... probably overly so, and paid special attention to the crotch lining. This time, there was no doubt in her mind that she saw him take a whiff from the dirty garment. It disgusted her and made her more uneasy.
“That’s a good gurl,” he said smugly, enjoying the overextension of his powers. “Naow, turn ‘round and put yo’ hand on the truck and ben’dover.”
“What?!” Gwen asked, her voice filled with worry. “You’ve searched everything, I clearly don’t have anything else on me.”
“Nah, yo’ don’t got anythin’ on ya, but since ya lied to me, you might o’ got somethin’ in ya.”
Panic filled Gwen’s voice, “NO, PLEASE ... I don’t, I SWEAR!”
“You’ll be swearin’ if you don’t get yo’ hands on that truck naow, ya’ hear?”
Gwen turned around, her hands trembled and tears dripped down her face. This was more humiliating than being forced to have sex with people. At least then, it was in a private room and only those involved knew about it. At any point, a car could drive along and see her naked and getting searched like a common criminal. Still though, she placed her hands on the truck and bent over. She couldn’t see Joey or anyone else, just the window of the truck and the road on the other side.
SNAP!
The sound close behind her made her jump; it was the sound of the sheriff putting on a tight latex glove. It sent terrified shivers down her spine, made only worse when she felt his hands on her bare ass, spreading her cheeks apart. A finger pressed against her backdoor; she grimaced as she couldn’t get herself to relax. It was only exacerbated by the sound of a car approaching on the road.
“ ... please don’t see me ... please don’t see me...” Gwen repeated to herself softly, over and over again as the engine grew louder.
She could feel one and then a second finger poking around in her ass, stretching it out to look for whatever he thought might be hidden in her depths. As always, he was being thorough, possibly for his pleasure and possibly to humiliate her ... probably both.
From her position, she couldn’t see the car till it was within twenty feet of the truck. The driver, a middle-aged man with wife in the passenger seat, slowed down as they passed. She could see the look of disapproval in the wife’s eyes and the grotesque mix of judgment and lust on the man. She didn’t know exactly how much they could see of her or if they could tell what the sheriff was doing, fingers wedged in her colon, but they knew enough.
“That’s one...” the sheriff said gleefully, enthusiastically enjoying his work. She had her legs shoved apart more and felt his hands on her pussy. The gloved hands peeled her lips apart from the back, spreading her open to the elements. His fingers roughly dove in, pulling and spreading her insides apart. He was so close, the rim of his hat was resting on her ass. He could look deep down into what used to be a private place, seen only by her doctor on occasion, and herself once while holding a mirror. Now it was practically a public park, open to use if you paid at the gate.
“I don’t see no cherry in he’re,” the sheriff crudely remarked. “Looks like a few fellas’ been makin’ house calls, eh missy?”
Gwen couldn’t stop herself from saying, “That’s none of your business!”
“So, I’m righ’, ain’t I? You a little slut, miss?”
“I’m not.” Gwen replied, wishing she could wipe her eyes, but her hands were still planted on the side of the truck.
Gwen felt his hands pull away from her sex, the lips slowly closing up again. She hoped the ordeal was over, but she was wrong.
“Don’t lie to me, girlie...” the sheriff moved close behind her, she felt something hard and smooth pressed between her legs. She wasn’t sure what it was, but she had a suspicion. “What’s yo’ name, girlie?” the sheriff demanded.
“Gw-Gwen...”
“Miss Gwen, anythang you say can and will be used agais’t you. Are you a little slut?” he asked again.
“N-no...” Gwen replied, then yelped as the object was shoved inside her pussy. It was long and thick, and from the way the sheriff stood, it wasn’t his dick.
Gwen looked down between her legs and saw the end of his baton splitting her lips and stuffed into her snatch. It didn’t hurt, at least once inside, but it caught her completely off-guard. So much so that she missed the sound of a car driving past, its occupants rubbernecking to see what the fuss was about.
“You’s givin ‘em a show, Miss Gwen,” the sheriff laughed, twisting the baton inside her. “You gonna give me the truth naow? Are you a little slut?”
“Y-yes, I’m a little slut,” Gwen cried out. The humiliation of everything was worse than the depravity. Sadly, she had gotten used to that by now.
The sheriff pressed his lips to her ear, “Gooood, a good girl would go to jail ... a slut has options.”
“What?! My ... options?” Gwen was confused but not surprised. This sheriff seemed like a pig, after all.
