Cisco and Caitlin were working on what Cisco was calling "Sexy Suit 3.0" in the fabrication room while Barry and Stella were practicing in the partition room. The two of them had been working alone for a few days, and Stella was getting better at her control. Cisco had made each of them a panic button in which, if pressed, would release knock out gas into their practice room. No questions asked.

Barry was excited. There had been a few slip ups here and there. Barry had taken to putting a condom on before he went into a session. Just in case, but she really was getting better, and he hoped that in a month or so she would be able to go out in public without causing a supernatural orgy. He was also exhausted though. Barry had never been more sexually frustrated yet at the same time, sexually fulfilled, in his life.

He was starting to miss out on things with work and his home life, so he had made plans to have dinner with Joe and Iris that night. All of them were working so hard though, that time had gotten away from him, and Barry was late. Iris knew that Barry was working on something secretive, and she knew how engrossed he could get in a project. So she offered to head over to Star Labs and pick Barry up since their food was getting cold.

Iris walked right past Cisco and Caitlin without them noticing her. She smiled to herself, knowing that those two could be just as engrossed in a project as Barry, and decided to go find him herself. It had been a while since she and Barry had hung out, and she was looking forward to their quiet evening in, just the family.

She almost passed the practice room. That is, until she heard grunting and moaning. She panicked. Was Barry hurt in their and his friends hadn't realized it? A million scenarios raced through her head as she raced into the room. The one she found in front of her was not one of them.

Barry, her Barry. The guy she had had a hundred sleepovers with in her lifetime. Was standing before her in all of his glory, his supersuit bunched up around his ankles, and he wasn't alone. Iris gasped as she realized what what was happening. The mystery girl was riding Barry like there was no tomorrow. Iris should have been embarrassed. She should have been horrified. She wasn't.

She was irreversibly, instantly, insatiably...turned on.

This was not her. She did not think of Barry in that way. She certainly didn't think of women in that way. But all she could think about was how good their skin looked, grinding against each other. And how much she wanted to lick it.

She wouldn't of course, could o't. She would never. Then why am I walking closer? She was o't even conscious of her actions as she ran her tongue along Barry's collarbone and pressed her body against his. The girl, the beautiful, mesmerizing girl, grabbed her by the shoulder and pulled her in for a passionate, fiery kiss unlike anything she had ever felt. She barely heard Barry's words as he spoke.

"Iris? Iris! Oh fuck Iris! The button! Stella push the damn button!" Iris had no idea what she was talking about, but she did not care.

Iris woke up on a surgical cot. She was confused for a moment, but as she looked over and saw Barry's guilty expression everything came rushing back to her. "Wha...what?"

"Iris, I'm so sorry!" Barry blurted out like he had been waiting to say that the whole time. Iris was baffled.

"You're sorry? I'm the one who….why the hell did I do that?" Barry winced at Iris's confusion.

"It wasn't you're fault. Stella's power has to do with pheromones. She causes intense sexual attraction in anyone she comes within proximity of." Iris sat up, trying to process what he was telling her. Barry had dealt with some weird shit this year..but this?

She looked him in the eyes, mostly because he was trying to avoid eye contact with her. She could not let this get weird. She could not stand Barry feeling weird around her. She needed to understand. "Barry if that's her power then, what the hell were you doing alone with her?" Barry held her eyes for a second, and she felt a little victory in getting over that hurdle. He sighed and ran his hands through his hair.

"We worked as a team at first but that got awkward." Iris snorted.

"I bet." Barry's eyes widened when he realised what she thought he was saying.

"NO! I mean well...Caitlin sort of...and there was that time with Cisco and Caitlin...but it's mostly just been me and….Ah hell, Iris it's not what you think." Iris smiled. A stuttering, nervous Barry, was her favorite thing in the world. But she could not let the poor boy suffer.

"Barry, it's fine. I mean. It's weird. But it's just like anything else you've dealt with." She was trying to reassure him, despite being weirded out by the whole thing.

"Not quite" Barry shrugged, doing that thing where he is talking more to himself than to her.

"Did we miss dinner with dad?" she sat up. Suddenly worried that Joe would be worried about them. Barry quickly shook his head.

'No, you were only out an hour. I called Joe and told him I needed your help with something. He put dinner in the microwave and is waiting on us."

She sighed in relief and then smirked. "You didn't look like you needed my help." Barry blushed.

"Shut up, Iris." He nudged her with his fist. Good, contact. He's not too freaked out to touch me. Iris was not sure why that fact was so important to her. "So should we go meet Joe or…" She was trying to play it cool, but the longer she stayed at the lab the clearer what she did was in her mind. She was not ready to fully deal with that yet.

"Yeah, sure… Did you want to meet Stella first or?"

"No," she said a little too quickly. He did that amused apologetic look. She started again, more in control. "No, I don't think I want to meet her tonight. Maybe tomorrow?" She squinted over at Barry, who had completely relaxed and was smiling.

"Sure, Iris" He offered her his hand to help her off of the cot. "Let's go." Iris could tell that Cisco and Caitlin were pretending to be busy as they walked past, and for that, she was grateful. She might be able to smooth over an incredibly awkward moment with Barry, but she was not sure if she could handle the knowing glances from his friends. As they got outside she squeezed Barry's hand.

"We've kept dad waiting long enough. How about you speed us back to the house?" He grinned at her and pulled her tightly against his side.

"Sure thing, hang on" and they were gone in a flash.

An hour later they were finishing up dinner back at the house. Joe was laughing and telling a story, but Iris could tell that Joe knew something was going on. She would absolutely die if he ever figured out what happened so she went for an old trick of hers. Answer just enough questions truthfully, so to dissuade his questioning, without giving her dad any real information.

"So did you guys get whatever it was you're working on finished." Barry's eyes went wide, he obviously did o't know what to say. Iris fielded the question for him.

"It's sort of a long term project." she answered smoothly. Joe raised his eyebrows.

"Does it have to do with a metahuman? Is this something that I need to know about?"

"NO!" Barry burst out. He shot a panicked glance at Iris, and then looked back to Joe.

"I mean, It does have to do with a metahuman. But she's not dangerous. She just needs help controlling her powers, so the lab has been helping her do that." Oh no, He's interested.

Joe leaned in. "Oh really? What kind of powers does she have?" Barry panic eyes again. Iris to the rescue.

"She's a really shy person. She wants to protect herself by not letting a lot of people know about her. She made us promise to keep it quiet. You understand." Joe look disappointed. Barry jumped in.

"I promise that if anything happens that you need to know about, we will tell you." He assured him. Joe sat back and sipped his coffee, somewhat satisfied with that answer. He grinned.

"So, Barry, You've been spending a lot of time with this girl?" Uh oh, Daddy's pushing for a hookup. If he only knew.

"Yeah, I...ugh I guess so?" Barry's eyes were darting all across the room.

"Is she pretty?" Joe asked teasingly Barry blushed.

"I guess she's fairly attractive." He answered evasively.

"Do you like her?" Old Joe was going for a more direct approach.

"No! I mean, she's sort of seeing someone." Iris was more interested in that answer than she should be. She decided that it was time to end the conversation. She sighed and stood up.

"That's enough with the twenty-one questions dad. Barry looks exhausted, and I really need to get some sleep." Joe stood up as well and together they cleared away the table. They said their goodnights and headed into their separate rooms.

Later that night Iris found that she could not get what happened out of her head. In her dreams, Barry had not made Stella push the button, and the three of them had gone further. She woke up with a desire that she had not felt in a while. She sighed as she considered her choices. She felt bad using Barry this way, but she was in the privacy of her bedroom. Besides, it was just this one time. She closed her eyes and continued her little fantasy as she let her hand slip between her legs.

Barry was touching her, rubbing her just where she needed him. He vibrated his fingers against her sensitive bud. Iris's eyes flew open with a sudden idea, she rolled over and reached into her nightstand to pull out her rarely used silver bullet. She winced at the sudden sound as she turned it on, dialing the gauge to the lowest setting to be sure that her family wouldn't hear it. She rested back on her pillow and placed the toy between her legs. Closing her eyes, she continued her naughty little fantasy.

Their clothes were long gone, and Barry was lavishing every part of her body with kisses. She let her free hand lightly glide along her chest as she imagined Barry's lips on her, taking the bud of a nipple and plucking it lightly, imagining his teeth grazing against them. He licked down across her belly and gently nibbled at her hip before settling between her legs. Iris turned the setting up. Barry's tongue darted out to taste her ,once, twice. Then he pursed his lips around her nub and began to suckle. Iris moaned out loud as she turned the toy up as high as it would go, uncaring about the noise she was making as she chased her bliss. She moaned his name as she pictured his tongue darting in and out of her most intimate place. She shuttered into her release.

Iris tucked the toy back under her magazines in her nightstand and settled back in bed, not sure what she thought about what she just did. She felt better, less frustrated than she did before, and maybe things would go back to normal now that she got that out of her system. She felt guilty though. Barry was her best friend, practically her brother, and fantasizing about him to excise her excess horniness was not a very sisterly thing to do. She reasoned with herself that it was just that one time and would have never had happened if she didn't get blasted with pheromones hours before she went to bed. She snuggled into the comforter and got comfortable, smiling to herself, that was pretty hot though. Iris drifted into the best sleep she'd had in months.

Next door, Barry was laying awake in bed. Did he just hear what he thought he did? He could have sworn he heard Iris moan his name. He sighed, dismissing the thought, all of this time with Stella and her super pheromones were turning his every thought into sex. He made a mental note to fix the buzzing light bulb in Iris's room tomorrow as he drifted off to sleep.
