With persuasion

Tanya smiled mischievously and suggested: "Nadine, you really have to try it out before you reject it. You can't understand the feeling unless you experience it for yourself. Maybe join me here?"

Nadine hesitated as she gazed at the soaked bed. "I don't know, Tanya. It just feels so strange to wet myself. It's not normal. And you're my sister, we shouldn't do that." Tanya rolled her eyes. "Nadine, normal is boring. You need to break out of your comfort zone and try something new. It's really not as bad as it looks. And we just cuddle."

Nadine bit her lip, unsure whether she should accept Tanya's suggestion. Finally she said: "But what if I don't like it at all? What if I feel uncomfortable?" Tanya giggled slightly and replied: "Then you can still chalk it up to the strangest experience of your life. But who knows, maybe you'll discover something you never expected."

Nadine sighed and took off her shoes. "Okay, Tanya. But if this goes wrong, it's your fault."

Tanya beamed with joy and made room for her sister. "You'll see, it won't be so bad."

Nadine, who was already dressed for the day, stripped down to her underwear and hesitantly lay down on the wet bed, flinching slightly when the liquid touched her skin. Tanya grinned at her. "Well, how does it feel?"

Nadine frowned, trying to describe the unusual sensation. "It's... wet. Very wet. And smelly, but also warm."

Tanya laughed. "Yes, this is the first impression. But just wait, it'll feel much more comfortable in a minute." She spooned her sister, pulled the blanket around them and hugged her, cupping her breasts carefully.

Nadine winced, but then she felt a strange warmth spread through her. "That's really strange, Tanya. But it doesn't feel as bad as I thought it would." Tanya grinned triumphantly. "See, I told you so. It's like a warm hug. You just have to go for it. On the topic of letting go...", she said and started to leak, wetting her sister's ass in the process. "Tanya!" she exclaimed, trying to move instinctively, but suddenly pulling back into her spooned position, finding the new warmth a little erotic...

The initial uncertainty gave way to a feeling of intimacy. The warm wetness around her seemed to embrace her, and the closeness of her sister was something she missed for way too long.

Tanya smiled contentedly. "You see, sis? You like it, don't you?" Nadine also smiled, her face slightly red. In stark contrast to what she had said and felt earlier, she wanted to touch herself and kiss her sister. It turned her on very much after she had given in and ignored "common sense" and what everyone else might think of her.

The sisters spent several more hours in the soaked bed. They found a new level of connection in their unique world of sibling love that would deepen in the days to come.
