Light of the Firefly 18+ (Timeskip!Tsukishima x OC) Mini Series

Part 3 (NSFW)

Last Part:

Weeks went by and the void in Tsukishima's heart was slowly being filled again. It almost baffled him how quickly his resentment melted the moment they kissed each other. He had almost forgotten about the past, just trying his best to make the most with his newfound family. He had to admit that he was still quite new to fatherhood, taking each experience, one step at a time. However, he had to admit, there were some moments he looked forward to, just like right now.

Tsukishima was laying on his side, one arm draped against Hotaru, keeping him warm as he snoozed peacefully. The tiny tot was knackered after a fun day watching his father practice for his volleyball competition. The older man watched Hotaru's chest heave gently, before he reminisced about earlier. While Tsukishima practiced, he had to admit, when he heard his son yell

"Papa!" So excitedly, echoing in the gymnasium making Y/n flush at the sudden attention drawn to them from the court.

He felt a sense of pride, from how excited Hotaru was to see him. It made him feel like he was doing his job as a parent, correctly, because of how happy his son was, every time they were together.

The door opened cautiously as Y/n crept in, giving him a warm smile before she slipped into the other side of the bed, quietly looking at him. Tsukishima looked back at her, as she gently ruffled Hotaru's hair, keeping him relaxed as he slept

"How do you get him to sleep so quickly?" She whispered and he raised a brow

"I read my research papers to him as a bedtime story. Knocks him out pretty quick." He responded and she bit back a giggle before her hand slipped from Hotaru's hair, to slide down and place itself on top of Tsukishima's hand, fingers gently caressing the back of his hand.

"You're doing so well with Ru... It's like my dreams have become a reality, watching you both together..." She said and he kept quiet, thinking of his words carefully before he muttered,

"Mine too..." He locked his eyes with hers... She couldn't pick up the emotion on his face, but she heard it through his voice

"...because we're together again..."

Y/n felt her heart almost skip a beat, he had those rare moments when he would show his softer side and they became more frequent whenever they were alone. She kind of felt guilty, the night they got back together. She refused to go further than their kiss, what held her back was the fact that it had only been a day and they jumped right back in as a couple. As much as she wanted nothing more, three years was a long time and she wanted to learn about everything that happened in his life during that period.

Sex so quickly, didn't seem like a wise decision. Tsukishima would never go too far during their make out sessions, even though he was almost over the edge because he had craved for her so long, he still respected her decision. He didn't want to think with his dick, after all. Any wrong decision made, could affect his relationship with his son.

He certainly didn't want that...

Besides, after that night, he learnt that parenting wasn't always bliss. He had experienced Hotaru in his terror mode within the first week of learning he was a parent and he had to handle it without Y/n because she was out on a delivery.

After trying everything he could, he ultimately gave up, carrying the wailing boy at arm's length to his friend's house.

Yamaguchi was surprised when he opened his front door and Tsukishima dropped a still crying Hotaru in his arms with an irritated look

"Tsukki!?" Yamaguchi stammered before his taller friend pushed his hair back in exhaustion

"Make it stop..." He said and his green haired friend raised a brow
