Tiffany moaned softly in response. The boy did not know how to latch on correctly, so her nipple hurt.
Alarmed by the sound, the boy glanced at her face. She was still asleep, her mouth opened by the moan. He calmed down, and turned his attention to her left nipple, drawing it into his mouth between his teeth and causing it to ache as much as her right nipple. She moaned again, again without waking up.
Tiffany was a sound sleeper, the boy realized, but she could still feel the pain in her nipples. He wondered whether she was a sleepwalker. He decided to experiment on her to find out. He whispered in her ear: “Your nipples hurt. Massage them with your fingers to see if that eases the pain.”
