Anna was babysitting for the first time in ages. She'd been hired by the attractive, wealthy couple who lived next door. The house was beautiful, all clean lines and modern furnishings. She sat in the living room, watching the television, while the baby slept soundly in the room next door. She didn't normally babysit, but times were tough.

Suddenly, a man walked in and smacked her ass. He was tall and muscular, with a chiseled jaw and piercing blue eyes. Anna recognized him as the husband of the couple. "What the fuck?" she exclaimed, jumping up from the couch.

"Relax, baby," he said, grinning at her. "I know you want it." He walked over to her and stroked her cheek, his hand trailing down her neck.

Anna backed away, shaking her head. "No, this is wrong," she protested.

He grabbed her by the waist and pulled her against him, nuzzling her ear. "No one has to know," he whispered. "It's just us."

Anna felt a confusing mix of desire and disgust. She knew it was wrong, but her body was responding to his touch. She pushed him away, trying to gather her thoughts. "I can't do this," she said, her voice shaking.

The man looked at her with a mixture of disappointment and desire. "Come on, baby," he said, pulling her towards him again. "You know you want it."

Anna pushed him away once more, trying to gather her thoughts. She couldn't believe she was having these feelings for someone she barely knew. But as she looked into his eyes, she saw something in them that made her heart race.

"Fine," she said finally, taking a deep breath. "But this is the last time."

He grinned and pulled her towards him, kissing her deeply. His hands roamed over her body as he pushed her down onto the couch. Anna hesitated for a moment before giving in to his advances.

As he kissed his way down her neck, Anna felt herself getting wetter by the second. She knew it was wrong, but she couldn't resist him any longer.

"Please," she moaned as he took her hand and guided it between his legs. "I want you."

The man smirked at her before pushing her onto the couch and spreading her legs wide open. He slid himself inside of her slowly, making sure to tease every inch of skin that touched hers.

Anna moaned loudly as he began thrusting harder and faster into her. She could feel herself getting closer and closer to orgasm with each passing moment.
