She gives into temptation

Mercy smiles to the two ladies. She convinces herself in her mind that this is to help Kyle hone his craft and not to see these two become sexier versions of themselves. She says, "I'm running experiments on a recruit with a strange new power. It could be the biggest shift for the world since Symmetra's hard light constructs or Mei's work with cryogenics. And I want to make sure they are guided in the right direction."

Like boobs and butts and sluts and sucking and fucking. Mercy thinks involuntarily. She's always been like this though.

"Blimey! This I gotta see!" Tracer says excitedly.

"Yeah, count me in too." Brigitte adds.

They follow Mercy to the medical wing where the experiments have been taking place. In the experiment room, Kyle is already ready and waiting. He had practiced some more last night without distracting beauties around.

Mercy says, "Kyle, this is Brigitte and Tracer. They'll be watching the experiments today. We'll start with the ball again and see if we can move up to something bigger, okay?"

Kyle nodded. He was ready this time. Mercy ran the trials and changed the color of the ball. This ends up boring the hell out of her two guests.

"I don't get it, luv. I could kind of see the ball changing, barely, but how's this a big breakthrough?" Tracer asks.

"This is stage one, Lena. Science is often slow. Though I suppose we can kick it up a notch. Let's head into the room."

As the three women enter the room, Kyle starts to get nervous. He isn't ready for this level of distraction. He starts to speak but Mercy cuts him off, "You've performed the tests perfectly, Kyle. So next will be changing the color of clothing. We'll start with Tracer's outfit. Do you have a preference in color, Lena? Perhaps something to match your girlfriend?"

Kyle notes that quietly. So Tracer is gay? Or at least bi. Is Brigitte her girlfriend? He shouldn't let his mind wander.

"Electric Purple or Hot Pink sound lovely!" Tracer says.

Mercy turns to Kyle, "Please put some hot pink into her outfit, Kyle."

She turns back to watch Tracer, focusing heavily on her to see the change. Knowing in her heart of hearts that she shouldn't do this and that Kyle isn't ready.

But Kyle wants to be ready. He focuses and tries his best to just change Tracer's outfit. That's it. Her pants turn to hot pink as does her goggles and the underside of her gloves. A few more pieces but her brown jacket stays brown. It isn't a total conversion. Mercy also notices her breasts go up about a cup size and her butt fill out more.

Tracer does not seem to notice anything but the pink change, "Whoa! It feels like I bought this outfit pink but I just saw it change!"

Mercy nods, "Now you see the power we are dealing with."

"You look amazing in that, babe." Brigitte says as she bends down to kiss her girlfriend. Tracer kisses back. Kyle is none the wiser that he changed this.

Then Tracer says, "You should go next, darling! What a surprise for Emily when we both get home."

Kyle notes that this is apparently a polyamorous relationship. It must be quite open given how freely they kiss in front of him and Mercy.

Brigitte goes to stand in front of Kyle and says, "Alright. Let's try blue and gold, yah? Like the Swedish flag."

Kyle looks at how much taller Brigitte is compared to him. And she's Swedish? He could kind of tell by the accent. Still, that means she's like a viking. A tall, sexy viking who takes what she wants. Which is probably sex. She's clearly in charge of the polycule she's in. And Kyle sees her workout shirt says that she likes working out because she loves eating. A big eater who must be extremely muscled except her bountiful breasts. You could probably bounce a quarter off her toned ass.

Kyle breaks out of his daydream to see that he just changed reality to everything he was thinking. Brigitte was not a foot taller, almost as tall as her mentor Reinhardt, and her muscles glistened as she flexed them in her shieldmaiden outfit. She has the cocksure grin of someone who gets what she wants.

Kyle falters, "I think I messed up, Dr. Ziegler."

He is soon grabbed by Brigitte and she starts to kiss him, "You're hot. Let's do it."

"Uh... Dr. Ziegler?" Kyle asks.

"Of course I will join, Kyle." Mercy answers, misunderstanding his question.

"Lena, get this on film. I want to watch it with Emily later." Brigitte says as she disrobes Kyle, then herself.

Kyle worries his power fill go off. He focuses on not triggering it even as he inserts his penis into Brigitte's ready pussy. Mercy puts one of her breasts in his mouth and lets him fondle the others.

This is an impossible task for in less than a minute, Kyle cums. When he does, his power goes off again.
