Her sons cum on her face

Pulling her head back, Emi saw that her suspicions were correct. Looking up at their faces, she knew that her boys here about to cum. Positioning, she prepared herself to let them paint her face, neck and chest.

Ichiro was the first to cum. Emi's eyes watched as thick ropes of cum shot out the tip of his cock and splashed on her face. She fought the urge to close her eyes and instead stared at her youngest son as she felt the warm, thick cream spurt onto her skin. Opening her mouth, she took an entire shot into her mouth, tasting his salty-sweetness on her tongue. His cock twitched a few more times, but each subsequent shot fell short of the mark, splattering on her chest.

Turning to Akira, her oldest son's first shot arched high, practically over her head. She felt the wet warmth in her hair just as his second shot splattered hard against her forehead. The corners of her open mouth curved as she stifled a laugh, knowing that she probably looked like something out of a bukake film. Akira's third and forth shots landed directly into her mouth, mixing his load with his brother's in her mouth. She relished the taste as she waited for Akira to shoot his last two shots on her chin and neck.

Leaning back, she used her tongue to further mix her sons' cum before closing her mouth, letting their salty flavor run over her tongue. Akira's was a bit more sour than his brothers, but the combination was the most intoxicating flavor she'd even had in her mouth before. Giving her sons a pleased smile, she swallowed the mixture and felt it slide down her throat.

"Fuck," Ichiro whispered, clearly enjoying that she'd swallowed their cum.

Standing up, Emi covered up her tits and started to button her blouse. She decided that she would keep their cum on her face, letting the world outside know that she'd just been the source of two young men's pleasures. However, as she adjusted her clothes, her mind cleared. She turned to look at the book, the one that had whispered secrets to her, she found that it was still open to the title page, but the inscription and the symbol were gone. There was no writing in the cover and instead, she found herself looking at a regular, first edition copy of “Nami-ko” by Rouka Tokutomi.

“Mother?” Akira said, his voice confused.

"What did we just do?" Ichiro asked.

Turning to her sons, she looked at their faces. She had no explanation for them, and she could not hear their thoughts anymore. However, she could not deny what she had felt and how much about their inner desires that she had known. And she couldn’t deny that she had felt something for both of them for a long time. And the feeling of their cum dripping down her face filled her with an inner contentment she'd never felt before.

As she encouraged them to get dressed, she knew that when they left the library and returned to the world, there would always be something different between the three of them. And as she moved toward the door, she still felt their cum on her face.
