Xu Bin leaned down and licked her large, white breasts, his hands quickly removing the last piece of clothing between them. This time, Shen Ruyu closed her eyes and lifted her hips to help him.
With her thong removed, he could see just how wet she was. He held up the soaked fabric, smiling at her embarrassed expression.
"You said you'd keep your promise, right? If you do anything funny, I'll squeeze it off," she threatened, her voice firm but her actions betraying her as she continued to stroke him.
Her eyes were drawn to his erection, imagining it thrusting inside her daughter. She shivered, feeling herself get even wetter.
"That would make Nan hate you, you know. She loves it when I make her come over and over," he teased, his hands roaming over her soft, full thighs, slowly spreading them apart.
He took his time, wanting to build her anticipation and embarrassment. Shen Ruyu's breathing quickened, her face turned away, but her legs parted slightly.
The most intimate part of her was now exposed to him. It was smooth and white, with a slight flush, and her lips were plump and pink, glistening with her arousal. He couldn't resist any longer, diving in to taste her.
He licked her folds, her unique scent and taste driving him wild. He sucked on her clit, and she cried out, quickly covering her mouth, her eyes wide with shock and pleasure.
"Does that feel good, Mom? Dad never did this for you, did he?" he asked, his voice husky with desire.
Shen Ruyu turned her head away, not answering. Xu Bin didn't wait for a response, his tongue delving into her, tasting her depths. He could feel her trembling, her body responding to him in a way it never had with her husband.
Her first taste of oral pleasure was overwhelming, her body shaking with the intensity of it. She imagined her daughter experiencing this same pleasure and felt a pang of jealousy and excitement.
Xu Bin found her clit and focused on it, his fingers entering her, curling up to hit that special spot inside. Shen Ruyu's body tensed, her orgasm building quickly.
"Cum for me, Mom. Let me taste you," he murmured against her, his tongue and fingers working in tandem.
Her body convulsed, a gush of fluid rushing out of her, coating his face. He looked up at her, a satisfied smile on his face, licking his lips.
Ding… Task completed: Seductive Mother-in-Law. Reward to be distributed shortly.
Looking at her splayed out before him, her body still shuddering with aftershocks, he wanted nothing more than to enter her. But he held back, knowing the system's rewards were worth the wait.
He gently stroked her body, kissing her softly, enjoying the feel of her soft, sweat-slick skin. He was curious about her sensitivity, wondering if it was due to something else.
Ding… Effect of genetic modification!
He was taken aback, not expecting that. Suddenly, a stream of knowledge flowed into his mind, explaining the effects of genetic modification on sensitivity and pleasure.
