(Sha Hualing's raid goes roughly the same as it does in canon, except since every one of his disciples are stronger, it ends more successfully.)
When Shen Qingqiu started to produce milk, he was sure it would end after its purpose was fulfilled or the breast ran dry. But when his milk ducts started filling immediately after swapping Liu Qingge from one nipple to the other, he felt a little crest-fallen. Maybe it was after a day?
Nope.
His tiddies were filling more and more everyday, causing a lot of discomfort. And spoiled robes.
After a quick talisman embroidery session, he started hunting out his shidi, the only one who knew. As luck would have it, he had set off already, leaving Shen Qingqiu to be filled with milk and very agitated.
If the other peak lords thought his snide personality couldn't get worse, they haven't met him filled with milk.
Poor Mu Qingfang. Shen Qingqiu had visited him once during this time and Mu Qingfang was nearly insulted to death the entire time.
His tiddies had also grown more sensitive. He couldn't do anything without them making their presence known. He couldn't even ride horses!
He had also noticed that they were starting to swell, making them start to look like a woman with a small chest.
So you can probably imagine his relief when he finally saw his shidi after a few weeks.
More accurately, his shidi found him, looking at him with eyes that said his injuries hurt.
His shidi had suffered WORSE without even flinching, continuing to walk without an once of acknowledging his wounds.
It was only a few bruises, but the sight of them along with his shidi's face had caused him to drag the man inside his bamboo house, somehow forgetting that it would jostle the milk in his chest, in which he flinched and almost screamed, sitting him down on the ground before sitting on the table for leverage(because screw manners when you've seen a man's tiddies!) and attending his wounds.
It had also caused him to open his robes and allow his Liu-shidi stick to his chest like a wet kitten, remembering how it caused his Liu-shidi to relax.
He didn't know when it started, but he had started to coo at him while petting his hair.
"Good, good Liu-shidi. Such a good boy. Just drink this one's milk, it will make him feel better."
He got a nuzzle in return.
It made his heart swell when he took care of someone. He loved to care for people that would let him. His disciples were an example of this, and now, apparently Liu Qingge was one.
Actually, maybe he should let some of his disciples drink from him? No, he wouldn't want them to feel uncomfortable.
When his shidi had finished drinking both teats dry, he had almost broke down in tears at the relief he felt from his tiddies being empty-ish.
His milk ducts were fast, okay.
Anyway, after his feeling of relief, he quickly looked at his shidi to complain to him about the pain and that he would have to feed from him at least once a week, preferably twice.
"Do you know how much discomfort you caused me when you were away?! The milk just kept building and building! I couldn't do anything without pain! Do you hear me, pretty boy?!"
"Yes."
What a dejected, sad face.
"You will need to be here more often! I know you like to run off, but it was very painful being filled with milk without release! Or you can invite me, but that has its own problems."
"You are always welcome to join me."
"Really? Since when? You always were glaring at me ever since I tried to save you!"
"I'm sorry."
Sigh. "It's in the past now, don't concern yourself with it. Point is, you need drink this one's milk more often."
"I will."
"Good. Now, why did you come to me when you could have went to Mu Qingfang, or even to one of the towns, for medicine?"
He was genuinely curious. Knowing Liu Qingge, he wouldn't have even sought help for just bruises.
And yes Liu Qingge, he caught you staring when he crossed his legs.
"I thought I would need an excuse..."
"For what?"
From the way his shidi was averting his gaze, he could guess.
Another sigh.
"You should have waited a day or two anyway, given your recent qi deviation. If you had, I would have been able to seek you out before it got this bad."
"You would let me... even without me being... troubled?"
His poor shidi, always not too good with words.
"Yes. Now, if it wasn't a constant thing I didn't know how to get rid of, I wouldn't have, but considering the circumstances, you can suckle when you want and when is appropriate."
"How did you even...?"
"..."
"Not important."
He received a nod.
He only just realized that his robes were still opened, and that his nipples had started leaking again. Liu Qingge hadn't just noticed, his eyes kept fluttering from his face to his milky chest and back.
He could guess that even with permission and this good timing, he would still ask to approach.
He gave him a slight glare before nodding. His shidi had taken the hint and gently leaned forward, putting his arms on either side of him, and started to nurse. He was pleasantly surprised when he didn't feel trapped and set off.
"If my robes are open and we aren't in the middle of a conversation, you don't have to ask."
His shidi had hummed, causing a slight flinch at the feeling. He didn't dislike it, his reaction saying that much, but it was precisely because of that reaction he didn't want him to do it again.
It didn't take nearly as long as it did when Liu Qingge had arrived to suckle all of it, but he kept him around all day as punishment, forcing him to drink every time he started leaking. Of course, Liu Qingge didn't see it as punishment, only that he had to somehow hide his pillar's reaction to every time his shixiong demanded he drink.
