It was all just a nice peaceful day. Black and Zamasu were in their cabin. Zamasu reading his book while Black just sleeping on his lap. "Such beauty", Zamasu said quietly. Black woke up and kiss Zamasu softly. Zamasu kiss back. "What are reading?", Black answered. "Oh, just a book about mortals", Zamasu replied. "There's no need to read such a stupid book, Zamasu, we did complete our plan", Black said as sat up.
Zamasu rolled his eyes.
Zamasu went to serve tea for him and Black. He poured the warm water in the tea pot. Black went to take a shower. When he was done, Zamasu was sitting on the chair outside in balcony. "Hey Zamasu", Black said as he took a sip of his tea. "Yes Black", answer Zamasu. "After tea, I was thinking me and you should train.", Black added as he smirked.
"Alright, but no teasing my body", Zamasu said annoyed. Black chuckled and transformed into super sayian rose. After Zamasu was done drinking his tea, he went to see Black to train.
It was a brutal fight, Black wounded and Zamasu's clothes damaged. "Damn, I hurt you" Black said, "shall we continue?". Zamasu nodded.
Zamasu dodged and fight back with Black. Black teased Zamasu as his sythe touched his back playful. "B-Black, what did I say about teasing m-", Zamasu was stopped. Black passionately kissed Zamasu. They teleported in their bedroom. "Black, what are yo-", Zamasu was cut off by Black's lips being smashed into his. "I love you Zamasu", Black said as he took off his cloths. Zamasu blushed hardy, he took off his cloths.
Black was on top of Zamasu. "Black..ah", Zamasu moaned as Black licked his neck.  Black gently nibble and suck on the kaioshin's nipples. "Ah..B-Black." They started to kiss for a few moments, then Zamasu felt Black trust into him. The trusting became faster and harder as both of them moan for one another. "Ahh....mmm~....Black!", Zamasu cried out in pleasure. The sound of pleasure filled the room, until the Black spilled his warm seed into Zamasu, which Zamasu did the same. They both panting and smiled at each other. A few moments later, they got clean, and headed for bed.
"I love you Black, goodnight", Zamasu said as he lay his head next to Black's chest. Black put his hand on Zamasu's head and the other hand near his waist. "I love you too, Zamasu, goodnight", Black said as he closed his eyes. As the night falls, as soon Black closed his eyes he said in his head "Just another day.....without you....sweet pea."
