The treadmill's hum slowed and stopped. Stan hopped off the device and started to stretch. He'd run five miles like it was a walk to the mailbox. More amazingly, he'd barely noticed. His heart thumped at a mildly elevated rhythm, but otherwise he didn't feel any fatigue or soreness. He could run another five. Hell, he could run a marathon, but he had another goal in mind.
He went to the guest bathroom and looked at himself in the mirror. It was impossible to deny the physical changes at this point. His jawline had smoothed out. Muscle caused his once loose fitted shirt to cling to his body. His stomach had flattened, and his chest had lost its narrowness as his pectorals swelled. Stan didn't need to pull down his shorts and examine himself to know that some more progression had happened in his crotch as well. Getting dressed for running had demonstrated perfectly well that his genitals weren't the size they once were. It struck him as odd that so many men would dream of an enlarged dick because so far it had only presented problems. His balls were too big to fit comfortably between his muscular legs. His dick was too large and frustratingly half erect to do anything with other than shove down the right side of his shorts. Running might not tire him like it used to, but that wasn't stopping friction from rubbing his cock half numb.
All that aside, Stan was pleased by what he saw in the mirror. Not the changes, but the results of his most recent run. Dark sweat stains covered the front and armpits of his shirt. He probably reeked of it. If Julie really could smell him, then this might knock her out. Stan wasn't sure why he was so skeptical about his wife's new superpower. Being able to smell whether or not a woman was aroused by simply being in the same room wasn't any more outlandish than watching Julie's breasts grow over three days or his own cock and balls suddenly appear to have a glandular disorder. But it was a bridge too far for Stan. If he accepted what Erica had so casually mentioned, then they had become involved in something much more complicated than a fertility drug. Wasn't it an invasion? To know how other people felt when they looked at you? It had already complicated things with Theo. How many of their other friends would want to fuck Julie? Or him?
Stan left the bathroom, eager to find his wife. After Erica left, Stan decided to go for a run. Julie had pouted for a while since she wanted them to get back into bed. Once that passed, she started cleaning the house with the same compulsion that drove Stan to exercise. Stan found her in their bedroom with half their closet pulled out. Several large piles of clothes and shoes had developed. Julie stood in the middle of it all wearing a tight fitting t-shirt that hugged her swollen breasts and a pair of cloth shorts that did little more than give a splash of color to her figure. As he entered the room, Julie's eyes locked onto his before drifting down his body to stare at his crotch with near unnerving hunger.
"How's this going?" he asked.
"We have a lot of stuff. Old stuff. I've found a few things that fit me, though. Look. These are from college." She turned around and bent slightly to show off the pair of light blue shorts. "They fit better than they did back then. But mostly it's your old jeans. There's a chronology of our weight gain here. I'm slowly unearthing the old us. Sort of glad we kept it all. Here, put these on." She snatched up a pair of jeans and tossed them to her husband.
Stan held them up to look at them. "Holy shit. I remember buying these. Senior year of high school. I wanted to look, I dunno, hip or something before I went off to college. So I had...a friend go with me and help me pick stuff out. These are the one thing that I thought looked good."
"Was the rest trendy crap you hated that you only bought because some ditz picked out for you?" Julie asked. "Who was it? Samantha?"
"I didn't know you kept track of my ex-girlfriends," he said with a smirk as he started to undress. "But yeah, it was Sam. She lasted about two weeks after that shopping trip, I think. Not sure I wore any of the shit that she picked out for me, but these jeans, these I wore almost every day." He shucked off his shorts and paused to once again adjust himself. The outline of his dick was entirely visible, and Julie made no effort to hide that she was watching it. Why would she? If she were dancing around in her panties, Stan would be watching her in much the same way. He snapped the jeans out to make them straighter, then started to pull them on. His lower legs went in easily enough, but his thighs posed a small problem. "Might have gone a bit too far in the other direction for these," he said.
"Go on. They'll fit," Julie insisted.
Stan pulled and hopped as the jeans slid over his muscular thighs. He had to struggle to get them over his butt, something he'd never even thought of as a problem for men in his entire life. Finally, he had to do something about the bulge. His hand squeezed into the front of the jeans, pushing his balls down between his legs and straighting out his cock down the right pant leg. He'd never wanted to just be soft before, but that would have helped tremendously. Maybe the jeans would constrict blood flow enough to cause his dick to finally go back to its old droopy self. The waist of the jeans had no issues though. It was even a bit loose. He fastened the button and then held out his hands in a "ta-da" motion.
Julie suppressed a giggle. "Can you move around in them? What about squat?"
Stan took a few lunging steps, then bent his knees to sink down into a low squat. The jeans resisted, but still allowed him to move. Cold air flowed over his lower back as the waist dipped below his ass crack. "Belt might help," he said as he stood back up. He turned around, and Julie had crossed the room. Her lips met his in a kiss as her hands wrapped around his back. She inhaled deeply and started to pull off his shirt. Stan helped, peeling off the sweaty cloth and tossing it away. Julie kissed and licked at his skin, her mouth moving over to his hard nipple and nibbling it playfully. Her body pushed his back until he toppled over onto the bed. She straddled him immediately.
As she bent over him to draw his lips into another kiss, Stan thought he smelled something pleasant. The familiar taste of her mouth distracted him for a moment before he realized that the taste and the smell were the same. His arms came up to hold her in place. His fingers intertwined with her hair as he held her in the kiss, tongues battling in their shared mouths. It was a taste and scent that he'd known for years, but he'd never really paid attention to it before. Warm, earthy, and inviting, it wasn't just her mouth, but Julie's whole body. He broke off the kiss and moved his mouth down to her neck, licking and kissing anything he could reach. Every inch of her was the same beautiful, alluring sensation. Was this what she could smell on him? Now that he recognized it, how could he have not noticed it on her all this time? Concentrating, he knew the scent grew stronger where she'd sweat, but near maddening from between her legs.
Julie sat up and pushed hard on his chest, forcing him to remain flat on his back. She scooted down to his thighs and went to work unfastening his pants. His cock strained to be free. As she brought Stan's attention to it, that strain grew into outright pain. His dick was squashed in his pants, and his balls were desperate for some breathing room. His hands went to the sides of the jeans, intending to wriggled out of them, but Julie stopped him. "No, no, no. I'm going to keep you in these. I'm going to fuck you while you wear the old denim that your high school girlfriend didn't like."
Stan was skeptical of his ability to do anything while wearing the jeans, but Julie's hands were hard at work. She unbuttoned and unzipped them, prying apart the fly as wide as it could go. Her hand snaked into his boxers, but the waistband was too high. Her fingers briefly grazed the root of his cock, and Stan grunted. She abandoned that route and went in through the Y-flap in his boxers. Grabbing hold of his cock, she pulled up, quite hard. Stan started to yelp, but then his dick sprang free, the head of it glistening with precum. It looked odd to see it standing out so isolated from the rest of him on a backdrop of denim.
