In a rather average home, we find a young man and a young woman currently going about their day as usual. They weren't related nor were they to be married-just simple roommates. Although, today was to be special as the woman was quietly talking to her Bannette in private...
"Ok, So Ban, I had a Idea of a 'Prank War' catch my drift?"
The girls Name was Tera, and she, unlike most Trainers thought Pokemon deserve 'Rewards' for service. The Banette nodded, zipping around a bit. 'What're you planning?' asked Ban. "Oh just a bit of fun~ The kind we could all appreciat." Tera had 6 Pokemon. Ban, the Bannette. Lilly the Chickirata, Victor the Serperior, John the Blastoise, Sin the Gengar, And Sarah the Braxien. 'Oh, okay! Who're we throwing pies at?' "Not that silly" she giggled "I mean bedroom fun!" Tera wondered where her roomate was as she planed this Surprise for him and his Pokemon. 'Oh...Sorry, I've been having a pie war with Sin...' said the plush with a smirk. "That explains his need for cream..." Guffaws 'Yeah, there have been some..."special" pies thrown at me from him... So, let's say we go prank Mason!' "If only I had a taste~ Well time to go tease him!"

Meanwhile, Mason was in his room, reading a book. Unlike Tera, he only had four Pokémon: Juv the Krookodile, Snake the Greninja, Jackie the Sceptile and Raven the Magmortar.

Go Get him Ban! And I'll record it!" She held up her Old Dex, which she turned into a phone and Camera with a few Apps. Ban then floated to his 'Right floated towards Mason's room, finding him alone for now...Good.

'Hey Mason~...'

"Yeah Ban?"
'Oh, nothing. Just acknowledging your presence...'
Mason shrugged and went back to his book before...he suddenly felt cold all over.
"Huh?"
He looked around but...Ban was gone. His arm started to move on its own... Uh-oh."B-ban! Come on! Joke's over, right...? R-right!"

He started to look around for the ghost, not realizing that he was next to Tera.

'Should I possess him for some "real" fun? His shouting hurts my poor, little ears.'
"B-ban...?"

"Oh Please, It would be Great!"

"Ban...? Hello...? T-this isn't funny!"

Tera bit into the top of her shirt, hoping to muffle her laughing "Can't wait till this gets going~"

He giggled before disappearing from sight. A few moments later, Mason went rigid before his eyes took on a purple hue. The room got warm and he began to strip.

"Ah I love Ghost types!"

'You and me both~.'

Soon, Ban had stripped Mason's body of clothes, hands already rubbing at his crotch to get it hard.

"Now only for the best part."

He moaned, a bit overdramatic with it- as his cock reached full-mast in only seconds. He teased the tip for some pre-cum, got some in the process, and began to rub it all over his soldier.

Tera new Mason Had a bit of a Kink for Ghost, among other things. Hence why he had been so nervous. Ban felt no resistance as he continued to molest Mason's body with his own hands, rubbing his chest while keeping a hand pumping around his cock.
'This is so much fun!'
Tera Began to Rub herself due to the actions of her controlled roommate.
"U-uh...Oooohhhh~..." His ministrations grew rather brisk, meaning he was getting close.
'T-tera...? Want some...h-help there...?'

The pleasure was affecting Ban by the sounds of his voice.

"With pleasure my dear ghost~" Tera quickly walked over and slammed my cunt on his dick.

"AHHH~!" Mason almost came right there, but Ban held it for Tera. He panted, laying his hands on her breasts before he tweaked the nipples.

"Oh Ban~!" Tera clenched trying to increase Bans Pleasure.

'A-ahh~...Tera~...! You...S-so tight~...'

Mason began thrusting into Tera, still at the brink of climax yet not pushing over the edge just wait.

"I-I know! And I...L-l-l-love it!"

'MMMPH~!'

He kissed along her neck, nibbling the skin before moving to her small breasts.

To add more to her pleasure, he began to moan onto your breasts, vibrating them like a motorboat before he tried to basically milk you. Even with her almost flat chest, it was overwhelming!

Not wanting to leave Tera unattended, he left his free hand to occasionally brush your clit.

I moaned like crazy, Cuming over and over.

When she hit her climax for a fourth time, Mason couldn't be held back anymore. He held you as close to him as possible, thrusting in balls-deep and staying there as he shot his pent-up load into Tera pussy.

'Y-yeah...They lead to..f-fun like this...'

Ban, and the rest of their Pokémon knew of Tera's schoolgirl crush on Mason, but kept it a secret from him on her behalf until she was ready to confess.
"I'm g-g-g-going to...head to my room to clean." She got up and carefully made her way to her room clenching as to not lose the feeling of cum in her. her way to her team. Ban made sure to wait on Tera's room door to close before coming out of Mason. Before the human could catch sight of him, he went through the walls to get to Tera's room.

One day, Tera was going to tell him ,but not yet.

And until then, her Pokémon's insistence will plague her.
