Brad pulled into Mindy's driveway just as the school bus was rounding the corner, she had asked him if he could stop by after work to help put some boxes in the attic since her husband Jim was out of town. He watched as his niece and nephew, hurried out the front door, backpacks bouncing, shouting their goodbyes to their mom. Mindy stood on the porch in her robe, her fiery red hair cascading over her shoulders. When she bent down to grab the newspaper Brads eyes widened, her robe shifted just enough for him to catch a glimpse of her bare skin beneath. Was she wearing anything under that robe? His pulse quickened as the kids waved at him.
"Hey, Uncle Brad!" they called in unison before darting off toward the bus.
Mindy straightened up and turned to him, her cheeks flushed from the morning chill. "Oh, Brad, I forgot you get off so early," she said with a warm smile. "No problem though--come on in."
Brad followed her inside, his eyes lingering on the sway of her hips as she walked ahead of him. Was she completely naked under that robe? His mind wandered, he felt a heat stirring in his stomach.
"Give me a minute to change," Mindy said, gesturing toward the kitchen. "There's coffee if you want some."
"Thanks," Brad muttered, his voice a little tighter than usual. He poured himself a cup, trying to steady his hands, but his attention was pulled back toward the hallway. Mindy and Jim's bedroom was at the end of the hallway..he noticed the door wasn't fully closed. He couldn't help himself. He peeked around the corner and saw her standing with her back to him, wearing nothing but a pair of cute white cotton panties. Her ass cheeks peeking out from the sides, Brad's mouth went dry. He quickly retreated to the kitchen, his heart pounding. I shouldn't be looking. I shouldn't be thinking this, she's my wife's sister. But the image was burned into his mind, and his arousal was impossible to ignore.
A few minutes later, Mindy emerged in a pair of shorts and a fitted t-shirt. She looked casual, effortless, and beautiful. "Thanks again for coming over," she said, giving him a quick hug and a kiss on the cheek. Brad stiffened, trying to hide the growing bulge in his pants.
"Anytime," he managed to say, his voice hoarse.
