As usual, just when she thought that she'd tracked down all her family's scattered clothes, Arlene found a blouse and mismatched socks tucked under the bed her 18-year old step-daughter was sleeping in. They were staying with Arlene's brother in the city for a few weeks during the summer, before Sarah went to college nearby. Arlene's older brother, Steve, had offered to run the laundry for everyone. Arlene figured she might be able to get the stray items into the laundry load if she caught Steve in time. She did catch Steve... but not in the way she'd expected.
Steve had the radio on, so he didn't hear her coming into the room. The washer was against the far wall, round the boiler room. As Arlene turned the corner, she gasped. There was her brother with his pants down around his ankles. He was facing away from her pulling something out of the laundry basket, then he turned sideways, toward the window, giving Arlene a perfect profile. Arlene's eyes grew as she realized that the lacy pair of black underwear, which he was bringing up to his face, were the ones she'd been wearing just this morning. Steve lifted the panties to his face and buried his nose into the crotch while slowly stroking an already vigorous erection.
His cock wasn't especially long, maybe 7 inches, about the same as her husband's. Arlene had seen longer pricks (that high school student she'd dated when she was in college must have been 9 inches and had regularly made her gag when she blew him -- it was worth it though for the mind blowing fucking he'd give her after his first orgasm went down her throat).
On the other hand, Steve's penis was very thick and looked to be as hard as a rock, despite the brutal pounding his hand was giving it. Arlene was turned on by the knowledge that inhaling her panties was producing such a strong effect on her brother's dick.
They had never been very close as children, since he was 10 years older than her. Steve had left home at 18 when Arlene was just a kid, and he hadn't been back in years. At 20, Arlene had married Dan, whose previous marriage had ended in a messy divorce, and moved away from their home city, where Steve still lived. Arlene had noticed Steve ogling her full figure when she'd arrived and when they'd hugged in greeting she had distinctly felt a twitch in his groin.

In the basement, Steve continued to hammer away at his hardness, completely oblivious to her presence only a few feet behind him.
Arlene knew that he was getting a noseful from those panties. Dan had been away on work (he was an airline pilot) for nearly 2 weeks, arriving back home on the morning they started their trip to her brother's place.
Sarah had fallen asleep in the back seat soon after they'd started the 6-hour drive to the cities, and when he was sure his daughter was unconscious, Dan had looked over at Arlene with a sparkle in his eyes. "Did you miss me?" he'd asked.
"Sure did" Arlene answered, innocently.
"But, did you miss me?" he asked again after reaching a hand beneath her short skirt and in between her legs.
"Hmm...I Sure did" Arlene answered, smiling mischievously. Even while driving, Dan knew exactly where to touch her and after 10 minutes of his increasingly daring caresses, Arlene had her own hand caressing her clit while his fingers were ramming into her slit. A minute later she was biting her lip and turning toward the window in order to keep from yelling as an intense orgasm hit. Dan had pulled out his soaked fingers from her pussy and licked her juices off with enthusiasm as he grinned at her.
Once she'd caught her breath, Arlene had decided to return the favor. Checking that Sarah was still asleep, and that they were on a fairly straight patch of freeway she reached out to stroke Dan's thigh.
There's something I especially miss..." she said. Dan raised an eyebrow, with a smile starting to form. "Well," Arlene said innocently "You know I'm on that high protein diet, and we just have chips and candy in the car. Do you think maybe you could help get something healthy in me?" She had licked her lips while leaning over his crotch and had released Dan's erection which by now was straining in his jeans. He hadn't had a chance to shower before they started their journey, and his crotch smelled musky and enticing. She pulled his hard cock from his boxers and started to lick the tip adoringly, before her head began bobbing up and down quickly on the shaft. The position wasn't the most comfortable for her, so she worked rapidly on his prick, teasing it with her hands, lips and tongue to bring him off quickly.
With his two week absence, and the novelty of what they were doing, Dan couldn't hold on for very long and soon he panted "Baby, I'm gonna cum...better pull off".
"Nuh-uh" Arlene told him, her mouth full of cock "I wan my snack and I'm gonna have it"
She'd barely said this when he groaned and released a thick stream of semen which hit the back of her throat like a soda siphon. Arlene choked a little, but her experience with that high school student was invaluable, and she swallowed down Dan's spurts of cum, swirling her tongue around his sensitive cock-head until he was spent, desperately trying to keep the SUV going in the right direction at a reasonable speed, while letting a truck pass them.
Arlene thought she saw a movement in the back, and glanced up, but Sarah was just moving in her sleep, her eyelids fluttering. Arlene held the last load of sperm in her mouth so that when she sat up and faced him she could let a little dribble out of her mouth and slurp it up again (for some reason Dan loved to see cum leaking out of his wife's mouth, and she enjoyed seeing the smouldering passion in his eyes when she did this). A few minutes later, they passed the truck that had overtaken them before: the trucker honked his horn enthusiastically and waved, causing both Dan and Arlene to blush as they realized what the driver must have seen.
Those same panties, which had been soaked with her juices from the day before, were now bunched up on Steve's face as he breathed in deeply with closed eyes, all the time punishing his manhood. Arlene was well over her initial shock and was starting to wet another pair of panties, reaching into her shorts to relieve her aching clitoris, when she saw that Steve was getting close to cumming. He pulled her panties from his face and wrapped them around his engorged cock, now using both hands to pump rhythmically into her silky black underwear. His bulging cock stretching the fabric of her panties was even more erotic than seeing his prick directly, and Arlene had reached two fingers into her hot pussy before she even thought about it.
Suddenly Steve started breathing faster. The song ended on the radio and she heard that he was talking to himself in the midst of his fantasy: "...you want me to fill your pussy with cum Arlene? OK, but then you've got to take my cock in your mouth and then later in your ass! Then I'm gonna spray all over your glorious tits! Ready baby? Wanna cum bath?"
It was all beginning to sound good to Arlene, and she only just managed to prevent moaning as she rubbed herself even faster, her body squirming almost as much as his. At last Steve reached his limit, and with a tensing of his muscular arms and legs, let out a deep moan as his first shot of cum splashed into her panties, some of it squirting out the side as the material stretched thin over his bulging penis. He continued to pump for what must have been a dozen ejaculations, the panties getting thoroughly drenched in the process. Arlene could see the white cum coating the crotch of the panties and some dripped down onto the basement floor.
