"Thats the thing that makes you my puppy, if you remember the oath your not supposed to take it off. But if you want me to exchange it then i will. Think of it like a promise ring." he said as he looked at him before he drug out his suit, It looked like his hair it was very calico like. "what do you think." he asked him

Well.. there was the oath.. and he didn't really mind it much so he left it without comment.
"Can you tell me your oath? I barely remember it..", he said and then looked at the outfit and smiled. "It sure looks like you.. You're good with constructing things, huh?"

"Your oath would not be wise to say for me, but i do have the message." he said as he showed him the oath 'I am nothing but a pet to serve my master. Failing to comply will result in my own punishment. My collar is a bond between me and my master, My master is the only one who can remove my collar, switching collars does not free me. I defend my master and he will defend me, we triumph because of this loyal bond between us, Pet and master.' i said

"Not mine. Yours", he sighed, rolling his green eyes.

"Mine is to keep you safe, and make sure that i love you." he said as he looked at him as he undressed and replaced his clothes with the suit, the back end folded out and he climbed in. "Babe can you strap me in." he asked him as he looked at him

"I want to hear it whole... And sure I can", he said and stood up, strapped Izuka in the armor while blushing soft as hd saw his naked ass. "Is that good?"

He smiled and it began to close up his was much larger than Mikotos suit. "Well its a little bit complicated but i will tell you. My oath for you. Is that until we can meet in the real world that i would care for you and give you my real love. And that when i found you in the real world that i would not treat you any different than you are now, even if you might become a puppy I would still love you." he said as he smiled "can't kiss me hit the button on the collar." he said waited

Hmm... So my have a form.. and your's not?", he asked curiously, tilting his head and then pushing a button on the collar. "And here is Izuka~ You look good on all fours~

"Well not yet but i was planing on getting it baby." he said as he kissed him "thanks I took alot of effort into it, its a lot larger than yours though." he said as he sat down and his tail began to wag

"Seems someone happy~ You look cute", said Mikoto and leaned forward, kissing his lips. "Wanna go for a walk or do something together?"

"Well there is something, Would you to have sex with me in here." he asked him as he looked at him

Mikoto blushed up to his ears when he heard that question as well as he felt just how his body reacted.
"I.. in this outfit?", he asked nervously, gulping hard.

"Well I made you a promise to stay in the suit besides, It would be something new for us to try. Please Mikoto-chan" he said as he looked at him

Seeing that eyes looking at him as well as hearing him call him that how could he possibly say no to Izuka. Looking away shyly he nodded.
"Fine..", he said barely audibly.

"He smiled and used his head to push him into the master bedroom. "Mikoto can you put your ass in the air cause i can lick it." he said he looked at him

Mikoto nodded when he was asked about that. He took off his pants and boxers and laid down on the bed, his face on the sheets and his ass high, his pink hole on the plain view.

He smile and began to lick his hole. he knew he was gonna be horny after that.

Mikoto moaned at the sensation and then even cried in delight. It was his first time to feel just how much more sensitive and suspectible for pleasure his hole was after changing. He grabbed the sheets, searching for some support as his gole started to twitch.

"tell me when your ready to ride the bull cowboy." he said before he continued

Mikoto would love to answer that but the only thing that came out of his mouth was another moan. The feeling coming from his behind was making his cock go slowly hard.

"how do you feel mikoto." he said as he stopped

"It's good.. very good.. M-more.. Fuck me..", he gasped out, blushing as his own words but he couldn't help it.

He got up on the bed his cock touching his hole, It was different because of the cock casing it was a tad bit bigger. Then he began to enter him slowly.

Mikoto moaned lewdly when his hole was entered into. It really was different but still he made sure to expose his hole even more, the feeling making him drool.

He movved in slowly as he began to fuck him. he search for his g spot. "how does it feel mikoto-chan" he asked hm

"G-good... It's.. so big...", he gasped out and then crying out as Izuka started to hump so he was stimulating his prostate with every move. "Ohh.. g-gods.."

He began to fuc him harder and harder it was almost natural for izuka to fuck him in the suit.

"T-talk.. dirty... please?", he gasped out, deciding to try how it would be to do that while his ass was going crazy for the stimulation it was receiving.
What Mikoto didn't realise was that in this was done with details so there was something that was called a knot. But for now he just simply enjoyed the rough ride.

"You like this big cock ramming your hungry hole dont you Love" he said as he looked at him as he looked at him

"Y-yess..~ I love it... It feels so good.. s-so big~", he gasped, his voice dripping with lust while his hole showed just how much he loved it.

He continued to fuck his hungry hole "Dont you want me to fill you up with my seed cowboy." he said as he looked at him

"Y-yes.. please... F-fill me, Izuka.. B-breed me", he gasped, his ass twitching from the dirty talking they were doing.

He smiled and then continued till he came inside of him. His knot was still in him he didnt want to harm mikoto so he stayed and then kissed him. "Puppy i love you." he said as he looked at him

Mikoto moaned and whimpered when something much bigger started to push inside him. It hurt but when it went inside it felt oh so good. That actually made him cum. Releasing his semen he felt his stomach bulding from the volume of seed he was being filled with. Mikoto even reached to it and touched it lightly, amazed.

"My knot is keeping me in you so i i have to stay in untill it deflates ok, I am sorry if it hurts to pull out" he said as he looked at him he put the back of his paw on his nipple and began to rub it

"It's fi- ahhh..~", he started to say only to moan when his nipple was touched, making his hole close tighter around the know.

He smiled and looked at him "does that feel good puppy." he asked him as he looked at him

"Y-yes, Master", gasped out Mikoto, before he even realised.
Blushing as he noticed how he called Izuka he wondered if he would like it. After all he loved to be called Mikoto-chan and puppy.. was kind of nice as well..

He looked at him and smiled before his knot began to deflate, he continued to rub to make him cum again

The rubbing continued and continued, making him squirm on the knot deep inside him and his ass twitch while Mikoto was letting out all sorts of sweet sounds of excitement. With it lasting for so long his cock was dripping with pre cum, showing just how much he loved it.
