Sometimes Gretchen found herself wishing that her boyfriend was older. She loved everything about Dustin, and most of the time she enjoyed his company immensely. They talked about teachers, and classes, and classmates, and assignments. They talked about the economy, and the environment, and the future, all kinds of subjects on which an older guy, she knew too well from experience, might not take her seriously.

Dustin was nice, he was sweet, he was deferential, qualities he must have gotten from his mother. Either that or he intentionally tried not to be the tease, the flirt, and the harmless boor that his father was. He was handsome. That he'd definitely gotten from his father. Classic clean-cut, square jawed, tousle-headed gorgeous he was, and the same genes had gone to his older brother, whom she'd only met once when his brother came home briefly from college.

Unfortunately, in bed, Gretchen wasn't much into nice sweet and deferential. She wanted take-charge borderline abusive domination, and Dustin insisted on treating her like the older more experienced partner. Which she was, mostly with guys Dustin's brother's age, and some with older men, like the aforementioned teachers, and fathers of kids she babysat, and one of her mother's brothers, and the minister at her church, and her father's best friend. None of them were serious relationships like she had with Dustin, none of them looked as good as Dustin, none of them shared Dustin's beliefs and attitudes, and since she'd been going out with Dustin for nearly 6 months, she'd been behaving herself admirably.

Well, except for the way she'd flirted with Dustin's brother, and let him kiss her (or had she kissed him?) but that was harmless. Or the way she responded to Dustin's dad when he teased her, especially the way she responded when Dustin wasn't there or wasn't paying attention. She would complain, and protest, but all the time she'd be shaking her blond mane around, or flashing some breast, or playing with her nipples so they'd be hard when he saw her. And she'd noticed that she was more openly affectionate with Dustin when his dad was in the room, and encouraged him more when she knew his dad was watching - not taking his hands off her ass, for instance, or sucking on his fingers. And she insisted on calling his dad "Mister" when Dustin and Dustin's mom were around, even though he kept saying "Oh come on, call me Jim" but then she called him Jim when Dustin and his mom weren't there. That was harmless too. Just a little harmless fun.

She enjoyed walking past Jim on the way to and from the bathroom after she and Dustin had fucked and Dustin was dozing off, and if Dustin's mother wasn't in the house she wouldn't bother getting dressed much to take the trip, and sometimes she'd even take a shower so that she could walk by one way looking freshly fucked and the other way completely wet, dressed only in two towels, or even just one towel, drying her hair with the other while she passed him. She loved the way he whistled at her when she passed, or just winked, or mock pawed at the towel from across the room. And she certainly didn't see much point in closing the bathroom door all the way when she showered, and she got a certain harmless thrill out of thinking that he'd been watching her through the door and had run back to the living room when she started out. In fact after the fourth time she left the door open he didn't try very hard to pretend he hadn't moved, and the sixth time he was still standing outside the door when she came out, and he gave a playful little yank on the towel as she walked past and she could have sworn he muttered "slut" under his breath as he grinned at her.

That had thrilled her so much that Dustin woke up with his cock in Gretchen's mouth and his bedroom door only part way closed.

On Dustin's birthday, a week later, remembering that Dustin had told her that his mother wasn't going to be home until late, and that Dustin had to work after school, she'd dashed over to Dustin's house and persuaded his father to let her in, stripped, climbed in Dustin's bed under the sheets and played with herself, bringing herself almost to orgasm over and over, stopping each time, her big round breasts heaving under the sheet, her hips bucking uncontrollably, not really caring too much that Jim knew what she was doing, but perhaps a little bit excited that he might be watching, and kind of wondering if he had his cock in his hand while he watched, and how it compared to Dustin's.

She rode Dustin hard when he got home, the door to his room thoroughly shut against parental view, hurrying to finish before Dustin's mother got home. Gretchen stayed for the birthday dinner and decided that Jim's hand on her leg and up her leg and tickling the back of her knee while Dustin blew out the candles was still harmless, but exciting fun. Nor did she see anything wrong with dropping by at other times when she knew Dustin wouldn't be home, accepting Jim's offer to wait, staring at him from across the living room, bouncing one long leg up and down on top of the other, blowing bubbles, and then peeling the gum off her face while Jim watched.

They stopped back by Dustin's house on the way to the prom. He'd told his parents they could take a picture, and Jim wanted to lecture him one more time about treating the car right, and calling in case of an emergency. Jim whistled at Gretchen. She smiled back, and stuck out her tongue when Dustin's back was turned, wondering if he guessed that the dress was all she had on. The prom was fun, and Gretchen loved the romance of it at all, the dancing, and holding Dustin close. But the cumulative effects of school, work, Gretchen, and the excitement of the prom were tiring Dustin out. Dustin didn't look up for any post-prom partying and Gretchen wasn't even convinced he was up to driving them home, and certainly not up to the post-prom fuck in her living room with her parents asleep upstairs that she'd been fantasizing about. Dustin actually made it to the garage, and onto the elevator, kissing Gretchen hard on the way up. He made it into the car and behind the wheel, and there he sat, staring, as though wondering what all the buttons and pedals were for.

As Dustin began to sway, Gretchen pulled him down onto her lap and stroked his hair gently until he fell asleep. Then she sighed, and called Jim on the car phone, still stroking Dustin's head with her left hand. Twenty minutes later Jim and Gretchen had Dustin arranged in the back seat of Dustin's mother's car, and were on their way to Gretchen's. They drove silently at first. Gretchen popped a stick of bubble gum into her mouth and chewed, watching Jim drive. "Thanks" she finally said.

Jim looked at her and smiled. "Thank you" he said.

"For what?" she smiled back.

"For calling me. For letting me drive you home after the prom looking that gorgeous. For looking that gorgeous all the time. For putting your safety and Dustin's safety ahead of your pleasure."

"My pleasure?" she asked teasingly.

"Don't play innocent with me young lady. This is not the way you were planning on your evening ending."

"And how do you know that?"

Even in the occasional illumination of streetlights and headlights Jim could see that she was turned on. Her face was flushed, her nipples were hard, and her prom dress was riding up her legs. "Because I know you. And I know you can't help yourself."

She started to respond, but they were pulling into her driveway. She stared at him instead, knowing he was right. "Walk me to the door?" she asked. Jim looked in the back seat where Dustin was still snoring, and escorted her into her living room.

Whether she reached up to kiss him and dragged him inside, or he bent over to kiss her and pushed her back is anybody's guess. But with her parents sleeping soundly upstairs and his son sleeping soundly in the back seat of his wife's car outside they fell onto the couch, their tongues entwined and their hands groping wildly. Somehow he got her over his knee with her ass up in the air, his left hand down the scoop neck of the prom dress tweaking her hard nipples, the right hand slapping her ass so hard that she was afraid it would wake her parents, whispering "this is for being such a bad girl you teasing nympho slut, you little bitch" alternating the slaps to her ass with fingering her clit, then turning her on her back and rolling on a condom that he'd put in his pocket on the way out the door after she'd called, entering her, the dress down exposing her breasts and up around her hips, driving down into her, her legs wrapped around his back, biting her lip, staring up at his handsome face, her hips bucking and her breasts heaving just as they had on Dustin's bed as Jim watched her.

She came first. Jim, unlike Dustin, had a great deal of stamina. She came second. Jim came third, gasping and grunting and ramming into her even harder with the spasms making her came fourth.

He kissed her. Gentler this time, but with authority, pulled up his pants and went outside to drive his son home, Gretchen's boyfriend home, home to his wife, to Gretchen's boyfriend's mother. Gretchen watched him go. "OK," she said quietly to herself, "not completely harmless."
