Yui's entire face went red, the kind of deep, blooming blush that spread down her neck and over her chest. Her eyes widened for a second, and then she looked away again, clearly flustered.
"Well… how about a little sip?" she muttered, still trying to keep her teasing tone. "I'm not producing milk or anything, but… I hope you make me one day."
Kouhei didn't fully grasp the deeper meaning behind her words, but something about them stirred a heat in his chest—and lower. Still, he didn't hesitate.
His hand reached out, gently lifting one of her breasts, fingers curling under it with reverence. It was warm and so incredibly soft. He leaned in slowly, lips parting, until his mouth found her nipple.
He sealed his lips around it, his tongue swirling gently, tasting the skin, feeling the texture.
The second his tongue made contact, her nipple hardened against his mouth.
