"I'll Make your slut hole feel very good." he said as he looked at him. "Do you like me fucking your slutty ass." he asked him

"I love... love it", gasped out Mikoto, only to moan and cum hard while being fucked so roughly.

He massaged his nipples and continued to fuck him roughly "I am gonna cum, Can i cum in your ass my love slut." he asked him as he looked at him

"Yessss.. Cum inside... cum..", he gasped out, lovig every second of the intensive pouding he was being given although he still didn't remember that he should call Izuka a master.

"I will cum when you call me what you supposed to call me puppy." he told him as he held back as long as he could

It was so hard to think right now so it took him few moments to realise what it was all about.
"Master.. cum inside..", he gasped out at last.

"Good boy." he said as he looked at him and began to cum inside of him

Mikoto moaned softly when he felt he was being filled so much. It made him feel a bit better.

"what now, master what do i do." He told him

"do what you want to break into him." He told him. "Mikoto do you vow to let me control you and no one else, even if it means losing a part of your self to me." he asked him as he looked at him

Mikoto needed to think about it for a bit to find his answer.
"Y-yes.. You can control me. But only you", he answered, his mind a bit more clear after he was able to cum at last. "You promised me to take care of me.. s-so.."
