Amanda, his own mother

Frank pulled up to the motel room, putting the car in park. He sat in the car for a moment, psyching himself up, before getting out. He was excited for this one. His client had requested he wear a suit, which he found hilarious. He knocked on the door, and a moment later, it opened.

He almost didn't recognize her. She was his mother, Amanda. She was a mature, gorgeous woman. After her son left home at 18 years old her marriage to his father fell apart, and she found herself in a slump. After a couple of years of depression she'd gotten back to the gym and gotten into great shape. She was not sure about dating, and now just wanted a fuck, so she booked Frank to come to her motel room, waiting for him wearing sexy lingerie.

"Frank?" She asked, her eyes going wide.

"Mom?" He asked, just as surprised.

They stared at each other for a long moment before Frank broke the silence. "I, uh, I can leave if you want."

Amanda shook her head. "No, come in. We can talk at least." She ushered him inside, locking the door behind him.

Frank couldn't help but stare at her. She looked amazing, much sexier than he remember. "Wow," he said, shaking his head. "You look incredible."

Amanda blushed. "Thank you. I've been working on myself."

Frank nodded. "I can tell. I'm glad. I mean, you look great, but it's good to see you happy too."

Amanda smiled. "I am. I really am. I just... I don't know if I'm ready to date yet. But I do want to feel desired."

Frank nodded. "I understand. That's why I'm here."

Amanda looked at him, her eyes lingering on his crotch. "You have quite the reputation," she said, her voice low and sultry.

Frank chuckled. "I do my best."

Amanda stepped closer to him, reaching out and touching his cock through his pants. "Is it true?" She asked, her voice barely above a whisper.

Frank swallowed hard, his heart racing. "It's true," he said, his voice hoarse.

Amanda looked up at him, her eyes full of lust. "Show me," she said, her voice barely above a whisper.

Frank hesitated for a moment before undoing his pants and letting them fall to the ground. Amanda's eyes went wide as she took in the sight of his enormous cock and balls. "Oh my god," she breathed. "It's even bigger than the pictures."

Frank grinned. "I told you."

Amanda reached out, wrapping her hand around his cock. She started stroking him, her eyes never leaving his. "You're so big," she said, her voice full of awe.

Frank groaned, his head falling back as she stroked him. "Fuck, that feels good."

Amanda started sucking on his cock, her lips wrapping around the head of his cock. She started bobbing her head up and down, taking more and more of his cock into her mouth.

Frank couldn't believe what was happening. He'd never thought he'd be in this situation, but here he was, his mother sucking his cock. He reached down, threading his fingers through her hair as she sucked him off.

Amanda started moaning, the vibrations sending shivers down Frank's spine. He couldn't take it anymore, he needed to fuck her. "Mom," he groaned, pulling her off his cock. "I need to fuck you."

Amanda nodded, her eyes full of lust. "Yes, please. Fuck me, Frank."

Frank didn't need to be told twice. He positioned himself behind her, grabbing her hips and pulling her back onto his cock. He started thrusting inside her, feeling her pussy clench around him.

Amanda moaned, reaching back and grabbing his ass, pulling him deeper inside her. "Fuck, you feel so good," she moaned.

Frank started thrusting faster and harder, feeling his balls slap against her ass. He couldn't believe how good it felt, and she couldn't believe how well he filled her up. Their passions escalated as he fucked her faster and faster, until they both came at the same time. They kissed deeply, and then both seemed to remember who the other was.

Almost awkwardly, they decoupled and got dressed. Embarrassed, Frank promised to call her later, Amanda agreed, and he left.

But after neither could stop thinking about what just happened. And if it would happen again.
