"God, this is so stupid." Get your shit together," Amber silently commanded herself as she stared at the white door. She'd been on the porch for almost a full minute, searching for the courage to knock. The last time she had stood in this same spot was nearly two weeks before, fluid leaking down her tanned leg and her body aching from arduous use. She'd been almost too shocked to speak when Kate Newsom had called her to babysit the family's daughter, Tracy, again. Now here she stood, beads of moisture filling her panties as she anticipated the night ahead.
Mark, Kate and Wade Newsom's son, opened the door after she finally knocked. He smiled a shit-eating grin when he saw her and made no attempt to hide his appraisal of her young body. At 18, Mark was only two years younger than Amber. His eager eyes took in the stiff nipples tenting her red t-shirt and the toned legs extending from her tightly-cropped black shorts. In any other setting, Amber would have been disgusted by a man leering at her so brazenly, but here, on this porch, she displayed herself to him, knowing he'd seen (and tasted and bit and slapped and...) it all before. After what felt like an eternity, he invited her in.
As Amber passed the threshold, Mark refused to move or open the door further, forcing her to press past him into the house. He felt his erection slide across her lower back, her ass grazing his thighs as she entered. Neither of them believed for a second that the touch was anything less than intentional.
"So nice to see you again," Mark intoned, closing the door. He adjusted his hardness in his jeans as she faced him, making no attempt to hide his movement. "My stepmom is upstairs getting ready. She insisted" - he emphasized the word - "that you go up to greet her." Amber started up the carpeted stairs and felt his eyes on her ass as she climbed. "Last door on the right."
Amber reached the landing and padded down the hallway. She stepped into the open room and was about to call for Mrs. Newsom when the door to the master bathroom opened.
"Oh, it's you, dear," said a cheery, and totally naked, Kate Newsom. Amber's jaw dropped in surprise. The older woman must have just finished showering, and Amber stared at the glistening skin, droplets of water clinging to perfect breasts and a small patch of hair between her thighs. "Don't look so shocked, Amber," Kate laughed. "After all, modesty isn't exactly our style, as you know."
The older woman sauntered to the dresser and pulled on a tight blue thong, talking to Amber all the while. Amber tried to keep up but lost the thread of dialogue as she watched the thin fabric disappear between Kate's firm globes.
"Are you listening to me?" Kate broke Amber's fog.
"Um, yes, I..."
"I was saying that we are taking our son out tonight for a special diner, and we are on a bit of a schedule." Kate stalked toward Amber, her bra dangling from her fingers. "I hope that you pay better attention to our daughter than you do to me." She was mere inches from Amber now and leaned in to whisper, "You know what happens when you get distracted. You aren't going to get," she ran a single finger down the girl's cheek, to her neck, "distracted." She planted a breath of a kiss on Amber's cheek and then whirled, pulling the bra over her arms.
"Clasp me," she ordered. Amber gingerly pulled the straps together. "That's better," Kate said, turning to face her again. She smiled. "Now, how is school going?"
"It's, um, going well," Amber said, jolted by the shift to small talk. "Well, sort of well. I have stats this semester, and it's killing me. My professor is awful. And the course is so much work. But I have to pass it for my major."
"So what are you going to do?" Kate asked as she continued dressing.
"I don't know. I guess study harder. Dr. Mattis is just such a hard-ass. He grades so strict."
"I would have thought you would respond well to a firm hand," Kate said.
"That's not what I meant!" Amber said, embarrassed. She had turned away from Kate as she spoke, and she yelped as a sharp sting erupted on her ass. She turned to see Kate holding a thin leather belt that she now started to wind around her waist.
"Don't talk back. Especially not in this house." A moment of silence passed. Kate's menacing look faded into something like a smile. "Here, I have something for you." Kate went to the nightstand while Amber rubbed the stinging spot on her ass. Kate handed her a small black box wrapped with a ribbon. "A gift. Sit down, open it."
The two women sat next to each other on the bed as Amber opened the box. Inside, resting in the velvet liner, was a u-shaped object. Amber held it up.
