Her neighbor and her stepdaughter

It was Julie Anderson, her next door neighbor. She lived in the house that Darlene had been showing off for, she had a son named Chase and a stepdaughter named Erin. She stood on her front porch with her stepdaughter, and for a brief moment, Darlene was terrified that Julie had caught her showing off to Chase. A second later she calmed herself down, realizing that it wouldn't make sense to bring her stepdaughter over for a confrontation about that. That was followed by the embarrassing realization that she had answered the door wearing nothing but her skimpy bikini.

"Hello Darlene!" Julie greeted her longtime neighborhood friend with a friendly hug and a peck on the cheek. She was wearing a thin blouse with no bra underneath, and some short shorts that clung tightly to her strong ass. Her body was just as attractive as Darlene's, with hers appearing a little more matronly because she didn't lose all of the baby-weight from having Chase. That left her ass and chest a little more full than Darlene's, she also had softer curves, with a little bit more fat around her tummy. Of course it made no difference to the local boys and men, she and Darlene attracted equal amounts of attention from them. It was capped off with her feminine face, soft and smooth and framed with her long brown hair. "You remember my stepdaughter, Erin, don't you?"

Since it was just the girls and nobody seemed to be making a big deal of her state of undress, Darlene relaxed and looked at Erin. "Of course I remember her, who could forget?" Erin wasn't biologically related to Julie, but she was just as beautiful. She was a captain of the high school cheer team, and she had to confidence to go with her looks and position. She had long blonde hair, sharp features, a thin waist, with a thick, bouncy butt and C cup breasts. Darlene saw that Erin's breasts were a little smaller than her own, but that could likely change if or when she decided to have kids. She was wearing a thin tank top with her high school's logo on the chest that bared her tanned and toned midriff, and some garbage bag shorts that showed off her shapely and equally tanned legs.

Erin offered Darlene a friendly nod and averted her eyes. Darlene thought for a moment that Erin had been eyeing her up, but she wrote it off as the same sort of examination she had given her and her stepmom.

"Well, Erin here graduated and is off to college at the end of the summer, but she's been a bit...restless since her dad and Chase went off on this long trip to bond. I figured I'd pawn her off on you since Howard is on his business trip circuit to make some cash for school by keeping your house in order."

For anyone else, it would have been a bit of an imposition, but Julie and Darlene were practically best friends, had been so for many years. So Darlene enthusiastically responded, "Of course, I'd love to have some help around here! How's $250 a week?"

That got Erin's attention. She nodded enthusiastically. "Sounds good to me, Mrs. Smith!"

"Great!" Julie grinned and gave Darlene another kiss on the cheek, though she accidentally pulled up short and it landed pretty close to her lips. "I'll leave her with you, Darlene, take care! Be good Erin!"

Darlene stepped aside and let Erin stride confidently into the house. As she shut the door, it clicked in her head that Julie said her husband and Chase were both out of town. So who had been watching her?
