Lan Wangji started to stand up to go to the bathroom when he heard Wei Wuxian gasp. He then turned around and smirked at Wei Wuxian, who covered his face with both of his hands and his ears were red, caused by seeing him naked.

"What's the matter sweetheart?" Lan Wangji grabbed his hands and pulled him into his embrace. "Are you shy? You've seen everything, and done almost everything to me…" he kissed Wei Wuxian and then he easily carried him into his arms.

"Where are you taking me?" Wei Wuxian held on to the thin blanket around his body since he was also still naked and shy about it.

"To the bathroom of course, you need a bath before we find your cousin and interrogate him."

"... together?" Wei Wuxian squeaked, and he was blushing.
"Well, that would make it faster, right?" Lan Wangji loved to tease him, he was really innocent at that age, unlike his reputation as the almighty hacker. And he loved him for every single thing that he is. He just needed to make him get used to his touch and his nakedness.

When he did not hear any objection, he chuckled and continued the short walk to the bathroom.

The bathroom was not as big as the one in Lan Wangji's penthouse, but the shower was big enough to accommodate two people at once, and that was exactly what Lan Wangji did. He took the blanket off and threw it away, then he opened the shower, set it to warm water, before he directed the water to both of them. He carefully poured shampoo on the long, luscious dark hair, and massaged the head carefully, just as he knew Wei Wuxian liked. He often did this back when Wei Wuxian was still in his original body. Then he continued by pouring and lathering the creamy body wash and massaged Wei Wuxian's body from his behind.

Wei Wuxian was enjoying the head massage, when he felt that Lan Wangji's big hand suddenly moved down, massaging his neck, his shoulder, his back, then the front. He gasped when his thumb touched his breasts and massaged them lightly, then they continued to move down slowly while the man kissed his ear. He never knew that his body was this sensitive to that particular man's touches as he unconsciously rubbed himself closer to the man behind him.

"If you keep doing that," Lan Wangji whispered in his ear, "I won't be able to hold myself back." Then he bit Wei Wuxian's earlobe. He was already aroused, the consequence of being in close proximity with the love of his life, who was naked, and rubbing himself all over him. When Wei Wuxian only moaned and guided his hand to his womanhood, he gave up. He rubbed that part with his fingers, making Wei Wuxian gasp and rubbed himself harder in his shaft, until he could not hold it anymore.
 
"Close your legs." 

Wei Wuxian obeyed him unconsciously, then he felt some hard 'thing' go between his thighs and he gasped from the friction it made. Lan Wangji held his waist tight and buried his face in the crook of his neck, then he started to move.

"Do you like it?" Lan Wangji moved one of his hands to hold Wei Wuxian's throat, pulled him back and kissed him. Wei Wuxian was blinded by the lust that flared within him, and he also moved in sync with Lan Wangji, feeling every friction, every touch, every kiss, until he reached his orgasm together with the man behind him. He tilted his head back to lean on Lan Wangji's shoulder when he was being turned around and kissed so hard until his lips were swollen.

"Someday you're going to be the death of me." Lan Wangji touched Wei Wuxian's forehead with his, his breaths were still erratic from the orgasm, and Wei Wuxian hugged his waist and pulled him closer.

"No, you won't, our lives are tied together, remember?" He kissed Lan Wangji's nose. "God, how come you're so hot like this…" he traced Lan Wangji's defined abs with his fingers. "I thought that nerd like you would be soft and squishy, wearing thick glasses with sweaty paws…"

"That was so typical, and I'm not a nerd." He squeezed Wei Wuxian's butt, making him squeal and slap his arm. "And what about you? I thought the Grim Reaper was an older guy who stayed in their mom's basement and talked about conspiracy theories on the dark web…" Lan Wangji nuzzled Wei Wuxian's neck.

"Hey, that's insulting!" But he giggled because Lan Wangji bit his neck playfully.

"Yeah, I know, I never thought that the Hacker King was a beautiful soul who sang like a siren, and had a face that could launch a thousand ships." Lan Wangji kissed him softly.

"Mm, keep doing that…" 

"What? Praising you? Or kissing you?"

"Both, please…"

"Gladly."
 
They both spent the next thirty minutes just exploring each other's bodies, touching and kissing, familiarizing themselves with every nook and cranny, before finally they got out of the shower, all wrinkly and satisfied.
 
Lan Wangji went out the bedroom door to retrieve the clothes that had been delivered to him by the loyal Xiao Xingchen, and gave it to Wei Wuxian. It was his usual white shirt and dark colored loose jeans with red belt, and red flat shoes, while Lan Wangji wore the identical white shirt and navy pants. They dressed up quickly and went out of the room when Lan Wangji's phone rang. He looked at the caller and picked it up.

"Yes."

"Second Young Master Lan, this is Detective Jiang. Can you come to the precinct today? We have the results from the bodies we dug out yesterday."

"OK."

"Good, see you then."

After Lan Wangji ended the phone call, he turned to Wei Wuxian.

"That was Detective Jiang. He asked us to go to the precinct to see the bodies."

"Great. Let's go then."

They stopped at a rice noodle stall along the way to the precinct to have breakfast. Wei Wuxian ordered the super spicy rice noodles with extra meat and dumplings, while Lan Wangji ordered plain rice noodles with vegetables and broth, both of them also ordered a pot of oolong tea to share, to cut the greasiness.

"This is unexpectedly good." Wei Wuxian slurped the last of the noodles and almost licked his bowl clean, when Lan Wangji took it away and wiped his mouth with his handkerchief.

"Why are you treating me like a child?" Wei Wuxian whined when his bowl was taken away.

"Because you act like one," Lan Wangji chuckled and pinched Wei Wuxian's nose. "Drink your tea, and let's go." Lan Wangji paid for the meal and after leaving tips, they left for the precinct.

They entered the now familiar precinct and ushered straight to the morgue where they met Dr. Xue, Detective Jiang, and Wen Qing. She nodded at Lan Wangji and looked at Wei Wuxian in curiosity. Jiang Cheng already told her about Lan Wangji's new girlfriend. They met every day after work, just for Jiang Cheng to take her home and accompany her if she needed him, since Wen Ning was admitted to Psych Hospital. Not the nice one like the Lans, but the state appointed one. She was grateful anyway since her brother would not survive in jail, and he was throwing tantrums almost every day in the psych ward anyway. They suspected that he was exposed to some kind of traumatic event to turn him into the mess he is. But Wen Qing tried to stay strong, with the help of Jiang Cheng, unexpectedly. The man stood by her side even when everyone else shunned her, and she was thankful for him.
 
"Wangji, Xian…" Dr. Xue called Wei Wuxian by his baby name when Lan Wangji cut him mid sentence.

"Uncle, this is Wei Ying, my fiance. You do remember her, don't you?" 

"Right, Wei Ying." Dr. Xue adjusted his glasses then he showed them the corpses. "These are all the bodies that they found in the woods, some of them still intact while the decomp on some of them was already a while. It went back about ten years or more." 

"Ten years?" Lan Wangji was baffled. "Ten years ago Jin Zixun was still around ten years old, so it's impossible for him to kill all these women."

"Ah, that's where you're wrong, nephew. Some of the body was males, and they showed signs of sexual abuse, especially the more recent ones." Dr. Xue took them to the corner of the morgue where a male body was prepared to undergo autopsy. "This is the freshest one we dug out." The body was that of a pretty male around twenty, thin, with a sign of bruises everywhere including his face. "The cause of death was ero-asphyxiation, an act of strangulation to achieve more sexual pleasure." Dr. Xue pointed at his neck, which was bruised in the shape of a thin belt.

"Are you sure it was an ero-asphyxiation? Not just plain strangulation?" Wei Wuxian asked Dr. Xue while moving his face closer to the body, in which Lan Wangji held him back by pulling his forehead away from the body.

"Well, from other signs that this body showed, I'm pretty sure." Dr. Xue showed them the telltale sign of ejaculation on his lower part, a penis ring, and butt plugs. The ankles and wrists also had signs of him being tied by some kind of a belt.

"So, a BDSM gone wrong?"

"Possibly. But take a look at this." Dr. Xue pulled the cover off another body beside the first. "This is also fresh, only a week old at most." 

Lan Wangji knew her instantly, since she was the mother of his number one stalker.

 
It was the body of Madam Jin.
