It was a common thing for the King to possess d3rlord3's body while the knight was doing something specific. Right now, it seemed the man was making out with his boyfriend. No problem; the King was actually very used to this. If he wanted to keep the façade that he was d3rlord3, he needed to act like his knight.
It wasn't a surprise for Avery to be affectionate with d3rlord3 while the King was controlling him. After all, the man was unaware of the differences between normal d3rlord3 and possessed d3rlord3.
At the start, the King didn't know how to react to the affection, and just did what he saw most humans who had relationships do: reciprocate it. The King used to do it just to keep the façade, but he knew that now he was just used to and even liked when Avery touched him. It was no wonder his knight fell in love with the slime.
The King didn't have a strict motive to keep coming back to d3rlord3's body. At first, he tried to make d3rlord3 come back to his command, to the crossroads, and bring Avery with him. But their connection was limited, since the knight's new house with Avery was very far away from the King's gates.
So now it was just for a view of the outer world, and for Avery. He knew Avery didn't have any feelings for him, just for d3rlord3 and what he thought was d3rlord3 while the King possessed him. But he grew to like the touches, the kisses, the hugs, and everything the slime had to offer.
That's why he didn't mind right now that Avery was removing his vessel's helmet and leaning to kiss his forehead. His hands held onto the slime's waist, bringing him closer. He wanted to feel his knight's boyfriend’s body heat. He wanted to feel that connection every time they did this.
Avery chuckled, leaning to kiss d3rlord3's neck. He helped the King to remove the rest of the armour. The King hated that his knight always used that, when he could use normal clothes and be able to be more close to Avery. Sincerely, it's a pity that he couldn't speak directly to d3rlord3, or else he would lose moments like this.
The King held onto Avery, pulling the man into another make-out session. He could already feel d3rlord3's body getting hard. It was funny for the eldritch god how easily mortals became excited. However, the King found it useful too, especially when he got to have moments like this with Avery.
The King moved against the slime, trying to rush things. Avery stopped him, already getting the message, and smirking in the way that made the King shiver. If there's someone the King knew that could kill him, even if he was immortal, it would be Avery. And, embarrassingly, the thought only excited the god.
The King watched as the slime took off his clothes. He wanted to praise Avery, but held himself back. He couldn't speak while possessing d3rlord3. Maybe one day he could bring Avery to his gates, and then the mortal would hear his voice.
The image was interrupted by Avery inserting two fingers into d3rlord3's hole. The King moaned, gripping onto the slime's arm so hard that his vessel's fingers entered it. Avery didn't mind, only slowed the movement with his fingers, making the King calm himself down. Avery knew every little thing about his knight's body, and it was embarrassing how it affected the King while he possessed him.
Avery started speaking, but the King didn't pay attention. He needed the slime to touch him, to fuck him now. He hated and loved how everytime he ended up having sex with Avery, the vulnerability of d3rlord3's mortal body affected him.
Fortunately, Avery seemed to understand and finally withdrew his fingers, lining himself with the King. The god pressed his lips against Avery again, as he felt the slime's cock go into d3rlord3’s body. He couldn't have chosen a better time to possess the knight.
Moans left his mouth when Avery finally started moving. Everything was so intense with mortals; it was so interesting for the King. He watched as Avery's hand went to his knight's cock, stroking it while fucking him at the same time. The King held onto Avery, the moans and gasps turning louder and louder.
He felt his vessel's body getting close, and he held onto Avery tighter. He didn't have to warn her for the slime to move faster. He loved this mortal.
The King arrived with a loud moan, muffling himself by pressing against Avery’s neck. The slime followed, with the King biting into Avery. He stopped only when the other asked for him to.
The King turned back only to gaze at Avery for the last time. His connection with d3rlord3 was ending, and he needed to use the last of his energy to change the knight's memories to make it look like he experienced this with Avery.
He gave the slime a last kiss, and returned the body to its owner.
