Unhealthy obsession (Haikyuu AU)

Chapter 36

It took Atsumu more than twenty minutes to return to his normal state of consciousness, and when he did, he made an alarmed and frightened sound in Sakusa's arms.

"Shhh, calm down," Sakusa whispered stroking his hair, "don't panic. You're here, you're fine. You're with me."

It was the first time Atsumu had experienced what it was like to be in subspace and such an experience could be terrifying even after being subjected to it many times.

"I ..." Atsumu wanted to say something, but his brain couldn't find the words.

"Are you okay?" Sakusa asked in a calm, soft, caring voice.

Atsumu looked towards Sakusa with a racing heart but immediately lowered his gaze again since he hadn't been given permission to look at him. Sakusa read his inner battle in his expression and decided that he could do him a favor by letting Atsumu look at him.

"Look at me, Atsumu," Sakusa ordered. Atsumu looked up at him again, eyes bright and a slight blush on his cheeks and the tip of his nose. "Answer me, are you okay?"

"Y-yes sir," he replied.

Sakusa could see something else in Atsumu's eyes, as if he wanted to ask something but didn't dare to do it because he hadn't been given an order, and Sakusa felt his erection painfully grow back between his legs as he saw the submission he showed to him even outside of a scene. He brought his hand to Atsumu's face and stroked the boy's lower lip with his thumb. Atsumu's eyes wandered weakly with dilated pupils and Sakusa smirked.

"Sir..." he muttered weakly.

"Yes, Atsumu?"

"Today's scene..." Atsumu's voice was heavy and slow, as if he was falling into a hazy endorphin sleep. "Electricity... why?" Sakusa smiled and pressed Atsumu's body even closer to his.

"Do you know the difference between a master and a sadist, Atsumu?" Sakusa asked. Atsumu shook his head as he breathed in the scent of Sakusa's perfume without taking his eyes off his master. "A master wants control in a relationship. He may or may not like to inflict pain on the sub, so a Dom/sub relationship is based on pushing the submissive's limits through commands, but that doesn't have to involve pain, "Sakusa said. "But that's not my case. I'm a sadist. I enjoy doing harm, watching someone's body suffer... As long as the submissive, that is, you, can bear it. I'll never cross a boundary that you don't want to cross. But your body is receptive, and handles pain and stimuli very well. You're the first person who have endured electricity well, even though, as you have already seen, it's not excessively intense. But the body suffers, tenses and contorts with spasms with each electric discharge, and not many people can take it. Not only are you my submissive, Atsumu. It's also pretty clear that you are a masochist and that your body is capable of handling things that most bodies cannot, even with prior training.

"I've seen it during the two months that we have been seeing each other. That's why I've thought about electricity, and I see that I wasn't wrong. I've been looking for someone... like you for a long time." Sakusa smiled at him warmly and Atsumu's heart raced. "You've trusted me enough to let yourself go and enter subspace, even though your body was suffering. You've done very well."

Atsumu blushed intensely and drank from Sakusa's praises and flattery as if nothing else in the world was worth it. He wanted to look away, but Sakusa was staring at him with such intensity that it was impossible to break eye contact. He was spellbound.

"Sir," Atsumu called.

"Yes?"

"Can I call you something else while we're not in a scene?" Atsumu asked somewhat self-conscious and unsure.
