Penny braced herself as she walked down the tree-lined sidewalk to Fred and Mona's house. Fred was her husband's younger brother, and he'd landed himself one heck of a catch. Penny couldn't help but feel intimidated at family gatherings whenever she was confronted by her tall, blonde, utterly gorgeous sister-in-law.
"You can do it, Penny. She's a woman, just like you!" Penny reminded herself. She'd tried to look her best, wearing a cute green dress that matched her eyes and showed some of her shapely legs. She kept her red hair cut into a short bob, and only the lightest dusting of make up was needed to conceal the spray of freckles across her nose. All in all, Penny knew she was quite cute. Adorable even. That was the problem. She barely reached five feet tall, and had slim hips and a nearly flat chest. She looked like someone's cute little teenage sister, despite being twenty-six and having been married for three years!
She'd always been content with her looks. A lot of guys, her hunky Joe included, seemed to love her face and her body. But Mona, that lucky bitch Mona, had what every guy seemed to crave. She was tall, with legs that went for days, big tits and the face of a runway model! It almost made Penny sick! Or would have, if she didn't have the tiniest little crush on her, herself. Not that she was bi, or even bi-curious, but the blonde was just that good looking.
"Did Fred get a new car?" Penny wondered aloud as she passed the big white SUV taking up nearly all of her in-law's driveway. Joe, her husband, and Fred were much alike. Tall, slender, sandy-haired men with steely blue eyes. Both men drove sensible little sedans. Penny looked a little closer. The gold rims on the over-sized tires were definately not the McHale boys' style.
Penny walked up to the door and had raised a small fist when she heard something that made her freeze.
"So BIG!" It was Mona's voice, but she must be saying that pretty loud to be heard through the door! Penny set the box down on the step as she heard muffled male grunts through the door. That have been Fred! The couple had only been married a month and no doubt they were still rutting like newlyweds!
"I should write a note," Penny giggled and fished a pen out of her purse. She scrawled a note on the package. "Congratualtions! Sorry this is late. Love, Joey and Penny." They'd ordered a nice set of hand-cut crystal wine glasses, but the order had suffered one delay after another. Penny was hoping to surprise her sister-in-law by showing up unannounced.
"Probably not the best plan," she giggled to herself as she turned, prepared to walk the two blocks through pristine suburbia back to her own home.
"God I love black cock!" Mona screamed, and Penny froze. Did she really just hear that? The little redhead spun on her heel and tried to peek through the window beside the door. She could just make out some blurry movement through the gauzy drapes.
"Take it, slut!" Penny heard the man growl. Definitely not Fred! Penny stepped back, wondering what she should do, but found herself trying to peek once more. With her face pressed so close to the glass, she could hear them more clearly now. The blonde squealed and moaned loudly. Whoever was with her made the occasional masculine grunt.
"I should really go home. None of my business," Penny whispered, but her tiny feet stayed rooted to the spot. Her husband had a killer engineering job, and Penny had quickly gotten used to the life of a pampered housewife. She loved cooking, shopping, writing poetry, and even dabbling in painting. But all the same, after three years of marriage a bit of boredom had crept in. Boredom and curiosity made a bad mix, and she lingered.
"Better than your husband, bitch?" the man asked.
"Fuck yeah! So much better than a little white dick. Now keep fucking me you black bastard!" Mona replied, nearly screaming. Penny had definitely heard that right, this time. She was cheating with a black man! Penny couldn't contain her curiosity any more, she tried the door.
It was unlocked. Holding her breath, she slowly twisted the knob. Fred did every bit as well as Joe when it came to his career. The house he'd bought for himself and his blonde bride was big, clean and new. The door glided open a crack as if sliding on ice.
Penny nearly gave herself away with a gasp as her eyes fixed on the erotic scene playing out in front of her. She'd seen Mona in her bathing suit before, a skimpy black bikini, when they'd taken family outings to their lake house. She had an idea what she was getting into or thought she did. Nude, the woman was breathtaking. Her golden tan skin gleamed in the sunlight streaming through the windows. She sat naked astride a big, muscular, equally nude black man who lay stretched out on the deep fuzzy rug in front of the fireplace.
"Ride it, slut!" the black man hissed. Riding it was exactly what Mona was doing. Her long, straight hair whipped from side to side as the woman bounced and jiggled and screamed. Her huge breasts, naked, round and firm, bounced with each motion of her body. Her long legs were curled under her as she slammed her hips up and down faster and faster.
Penny thought they must have been going at it for quite some time. The air conditioned house was cool and clean, but reeked of sex. Sweat dripped down Mona's curves, and the big black mitts that reached up and held her wide hips glistened with it.
The young redhead could only watch, slack-jawed, as her sister-in-law abased herself before her very eyes. She felt her modest cotton panties grow damp from the display. It was turning her on, and she blushed nearly as red as her hair from the shame of it. She had no business watching what was happening. But she couldn't look away.
"Cumming!" Mona screamed, and she rocked forward. Her hell fell in front of her angelic face as she braced herself by resting her hands on the man's dark, tree-trunk legs. At this angle, if Mona simply opened her eyes, she'd look right into Penny's face!
"Fuck!" the man grunted, his voice a deep, rich bass. He jerked his hips, pushing the slender blodne's body up and down as he stabbed up into her. He shuddered and thrust erratically for a few moments.
"I can feel you cumming in me," Mona purred. She pushed her round ass back into the prone man and ground her slinky, curvy body into his.
"Hope you're on the pill! Or you're gonna have a black baby to show your hubby!" the black man laughed richly at his own perverse humor.
"Would serve him right for having such a needle dick!" Mona chuckled, her voice husky with her own passion. She rolled off her secret lover and twisted around on the carpet to cuddle up against his heaving chest.
The guy must have been a weight lifter or something. His muscles stood in sharp relief under his damp, ebon skin. His herculean physique wasn't what made Penny's eyes bulge in shock, however. His cock stood straight up from between his thighs, as hard and black as wrought iron.
Penny had only had a handful of lovers before meeting and falling in love with Joe. Some were bigger than others, some smaller. Joe was the biggest of all of them though, with the longest, thickest cock she'd ever seen. She'd measured it once, just shy of seven inches. The black cock standing only a few feet from her greedy green eyes put even him to shame. Thicker than her wrist, and at least three or four inches longer than Joe, it dripped with cum and Mona's juices over a pair of wrinkly balls the size of lemons. The shaft was coal-dark, but the head a lighter shade of chocolate brown and flared like a mushroom. How had Mona taken that?
"Enjoy the show, little Sis?" Mona asked, her voice sounding lazy, half asleep.
"What?" Penny yelped, and gave a start. She stumbled into entry hall, tripping over the threshold to land on her hands and knees on the hardwood floor. When she looked up, all she could see was that tower of black cock. It was like it was staring at her!
"You heard me, Penny," Mona said as she got up and walked around the smaller woman to close the front door behind her. "It's not very nice to spy on people."
"I didn't mean to!" Penny whined and pushed herself up to her knees. Her dress was a rumpled mess, and she fussed with it to straighten the light green fabric over her waifish body. Mona's perfect long legs appeared before her, and the woman offered a hand.
"Come on, get up," Mona said as she pulled her sister-in-law to her feet. Even barefoot she was a good deal taller than Penny, and she smirked down at her. Couldn't she look just a little contrite? She'd just been caught having a fling after all. Instead, the beautiful woman just looked smug.
