Chapter 686: Chapter 686

"Mmm..."

Just as he started, Sister Ning furrowed her brow and couldn't help but let out a delicate moan.

Dazhuang was startled and quickly stopped, "What's the matter, Sister Ning, does it hurt a lot?"

Sister Ning, with her face turning red, glanced at me and then bit her lip, silently nodding, "Mmm, it does hurt a bit."

"Ah... I don't know if it's because I bought the wrong model or something, but every time I use it, it feels very uncomfortable."

Hearing this, I hurriedly said, "Sister Ning, I experienced the same thing before. It even swelled up. It's really better not to use it."

"Exactly, exactly, Qin Qin is right," Sister Ning nodded repeatedly, also giving me a grateful look.

Dazhuang said somewhat helplessly, "You all are using it wrong. Actually, I've heard from others that this thing should only be used when the mammary ducts are completely clear. If they're blocked, of course it will hurt."
