"What were you doing today?" Hayato demanded, as he pushed the other onto the bed of his room. His brow knits downwards. "Why were you talking to those girls?"
"Wait Hay-" Mitsumune was interrupted, the other mouth crashing into his, his tongue slipping into his with unexpected force. "Huumm."
"You should have come to me immediately." He continued, breaking momentarily. "Do you have any idea how hard it was for me to wait all day, wondering what they did to you?"
"T-They were just asking me for information, I swear wait-aaah." Mitsumune moaned, Hayato's hand quickly worked against his pants, grabbing his testicles.
"You don't need those girls. Or anyone else. You have me." Hayato's tongue worked on the other's neck, as he quickly removed his own pants, kicking them away. "I'm going to remind you who you belong to."
"W-Wait Hay-" He was again interrupted by the other's mouth, tongue pushing past his lips, intent on exploring.
Using his hands to spread Mitsumune's legs, he positioned himself between them, the tip of his cock pressing toward the other insides, "I'm going in."
"W-wait please, at least-" He didn't managed to finish the sentence, as Hayato was already fully inside of him in a couple of sharp thrusts. He cringed and a hard shiver wracked down his spine; a mixture of pleasure and sharp, tangible pain.
"It's not like you are a virgin." The other said, starting to move his hips. He normally didn't mind preparing Mitsumune, showing the other pleasure was his job after all, but right now he felt the other needed a lesson in belonging. "Look how easy I went in, I hope you are not fingering yourself when I'm not around. I told you that you could hurt yourself, you should let me do it." His thrusts increased in messy rhythm.
"H-Hayato-!" Mitsumune exclaimed, it was hard to say whether or not pleasure or pain was more prominent in his voice. "At least please-" Mitsumune's erection was thoroughly ignored, despite the precum leaking from the tip.
"Will you come immediately to me the next something like this happens?" He wanted to touch the other too, but he had to learn.
"Y-yeah. I swear. Now please!"
Hayato's lips curled into a smile. This was good. He didn't wait, and one of his hands snaked down to grip the other's neglected erection he pressed himself and his mouth against the other.
"I'm going to come inside you." He whispered. He normally liked to come on the other male's face or body, but this time he felt like he needed to be inside. Besides, there was always later.
Mitsumune didn't have time to answer, or perhaps he understood it was useless. As Hayato's thrusts became more erratic and lost their rhythm, he spilled inside the other, whispering, "mine, mine…"
That was perhaps enough for Mitsumune, who came into the other's hand, spilling all over their shirts and bodies.
Hayato's heavy breaths were filling the room, and Mitsumune's wetness on his hand, he immediately brought it to his mouth, swallowing it greedily.
Mitsumune didn't pay it much attention, it was something he always did since they started doing this. When he asked the other why he did it he answered: "It's a part of you. It belongs to me and shouldn't be wasted away." So instead, he closed his eyes, feeling the afterglow of their sex. Hayato would take care of the rest as well as him.
He always did.
