The young man took a step back and sighed.

"There's no way I can talk you out of it, is it? Fine... you can join me. But under one condition."

He raised his hand with the index finger pointing up. The demon crossed his arms in front of his chest and raised an eyebrow.

"And that is?"

"DO NOT do anything, ANYTHING that could end the ball in a disaster. Understood?"

Jun directed his finger at Juto with a serious expression. The summon just grinned wide, unaffected by it.

"Deal."

The young master just stood there with his finger pointed at the demon. Even with the deal, he didn't feel any calmer about it. In fact, he felt like things will get even worse. Juto just grabbed his arm and pulled Jun closer, wrapping the other arm around him. He tilted Jun's chin up to meet his eyes, which made his heart skip a beat.

"Relax. Now... if I may?"

He said slowly in a calming, deep tone. Asking for approval before draining his master's energy was always an important part of the contract. Even though their power difference was clear, Juto wasn't allowed to do things without his master's consent. Jun inhaled deep and nodded. He leaned in, wrapped his arms around the demon's neck and closed his eyes. It was a long, deep kiss of exchanging energies - energizing for the demon but exhausting for the master. The tall man tightened his embrace around the small body when it started to grow weaker. Jun slipped a moan when he felt at his limit, digging his nails in the demon's shoulder.

When they broke off the kiss, Jun felt a shudder and gasped for air.

"You're getting better at this."

The demon said and licked his lips with a satisfied look. The master just gave him a tired grimace in response. Juto chuckled and picked him up bridal style then sat him on the bed.

"This... better be... worth... it."

Jun's breath was shallow and he looked pale and sick, like being in a fever. He swayed a little in his seat.

"I may be a demon lord, but I do care about your well being, alright? Here."

Juto already retrieved a vial of a potent revitalizing mixture from Jun's drawer and put it in his hand.

"I need to make some preparations right away, so I'll be off for now."

He stood up after making sure his master took a proper sip of the potion. He stopped in the middle of the room and created a red demonic circle at his feet. A classic portal back to the demon world.

"See you soon. Oh, and one more thing. I'd suggest you pick the crimson red suit, the one you have on now does make you look fat."

The young man growled and threw a cushion at him, but it landed on the floor as the demon was already gone.

"What have I done..."

He mumbled looking at the empty space and felt the potion slowly kicking in.
