Here's one for Lisa and her crush David. Lisa's a bit different to write than other characters, but basically, I just had to give her some dialogue with big scientific words instead of normal everyday words.

David x Lisa: Scrutiny

It was a nice summer day in Royal Woods and everyone was trying to enjoy it however they could. The Loud siblings were especially finding opportunities to spend the time with their significant others. Many of them were engaged or married and the older ones were even parents already. And right now, across town at the Royal Woods Spa, one particular Loud sibling and her partner had something special planned to spend their free time.

Lisa Loud hadn't usually been one to express emotions, but even she was vulnerable to the all-powerful force that is love. Upon meeting a boy named David when they were just young kids, Lisa had developed a surprisingly strong level of fondness for him that even she didn't expect. He showed a great level of intelligence. Not quite as much as Lisa, but it was enough to impress her. He was also very mature and gentlemanly for his age which made her even more attracted to him. In return, David had grown very fond of Lisa the more he got to know her. He admired her unparalleled intelligence and how she put it to good use. And even though he thought Lisa's behavior was unsettling at times, it wasn't enough to drive him away from her. He also appreciated that she had a softer side and showed compassion when necessary.

The two young geniuses grew closer overtime to the point where they realized they had officially formed romantic feelings for one another. Everyone was surprised by how someone as stoic and sarcastic as Lisa, including herself, could fall in love but they weren't complaining. David was a good influence on Lisa and made her happier than she ever was while she had made his life better as well. Their families and friends were happy for them, Lisa's especially. They gained a lot of respect for David for being a good boyfriend to Lisa and for causing her to genuinely fall in love with. Something they weren't even sure was possible, but they weren't complaining.

For the most part, Lisa and David behaved like a relatively normal couple like Lisa's siblings and their partners. They supported each other, they learned to accept their differences, they went on dates just to have a good time and much more. They also made many different accomplishments in scientific work as a team. They were happy together and certain they were meant for each other.

However, there was something that David couldn't help but be a little bothered by. As much as he loved science and considered it to be his passion in life just like his girlfriend, Lisa always seemed to be more into it than him and he had the feeling that she was a little too into it sometimes and that it distracted her. Most of the dates they had that Lisa planned would have something to do with science. They involved going to museums, studying nature, and conducting experiments among other things. David enjoyed it when they were younger, but when they reached adulthood, he wanted them to go on more practical dates like going to restaurants, movies, parties and stuff like that. Though he and Lisa managed to compromise and have equal opportunities to plan their times together, he just couldn't help but be bothered that it sometimes seemed like Lisa didn't know for sure if she loved him or science more.

The couple were now in their early twenties and currently taking much of the summer off from college. Lisa had suggested they spend a few days at the Royal Woods Spa, a place where she and her family had some interesting experiences. David agreed as he saw it as an ideal place for them to relax and enjoy time together. And they did for the most part by engaging in various activities the resort had to offer. They also wanted to spend some quality time alone and just enjoy each other's company. With them both being grownups now, they felt the strong need to have a more intimate relationship.

Right now, it was mid-afternoon and David was sitting at a bar down near the public pool area of the hotel with a cold ice tea and lemonade beverage. Lisa was up in their rented room preparing it for their time together. David was mostly happy he was getting some quality romantic time with his life partner. Unfortunately, Lisa saw it as yet another opportunity for a scientific observation. Since she had a knack for studying all kinds of human behavior, she was now interested in scrutinizing the acts of cuddling and making out. David was still willing to go through with it because she also agreed to do it because she truly loved him. He just thought it would be better if their affection for one another was the only reason they were doing it.

David finished his drink when a text from Lisa appeared on his phone saying that everything was ready. He left a tip on the bar's counter and headed back inside the building. As he took the elevator to the floor his room was on and walked down the hall towards it, he gathered up all the confidence he had and ignored the fact that Lisa intended to collect observed data of their session. He tried to only be focused on showing his love for her.

He reached the door to his room where there was a "Do Not Disturb" sign on the handle courtesy of Lisa. He took a deep breath before opening it and stepping inside. As he closed it behind him, he found the room dimly lit with soft, soothing music playing. The window curtains at the back of the room were closed and there were a couple of monitors with cameras, as well as a tripod holding Lisa's iPhone, facing the bed. But what really got his attention was Lisa laying on her side on the bed.

"Greetings, fellow lover," she said teasingly. "I hope I've made this enticing enough for you."

David was slightly taken aback. He wasn't used to seeing her like this, but it was as expected. "I must admit…" he replied. "You really planned this well."

Lisa smirked. "You know me, sweetheart. Always prepared for anything." She got up and approached her boyfriend. "And are you prepared to commence this escapade of intimacy?" she asked as she locked the door behind them and started softly massaging his shoulders.

David blushed deeply. "Ready as I'll ever be, Lis." He looked at all the equipment she had set up. "So what purpose do each of these serve?"

"Well for starters, I made sure to soundproof this room so that what happens in it remains in it," she explained. Then she handed him a pair of small plastic ear hooks. "And these are to keep our glasses in place. We've admitted before that we find one another more attractive with them on so wearing them will likely help us remain more attracted to one another."

"Always love the way you think," David responded as he connected the hooks on his glasses and attached them to his ears. Lisa did the same with her own pair.

She then indicated to one of the monitors. "This body scanner is to display our internal activity during the session. It will scan our brain activity and our pulses and blood pressure so we know how our bodies function during an act of romance." She indicated to the other monitor. "This is an emotion recognition device. It will identify and record our emotions so we can determine our level of intimacy."

Finally she got to the phone on the tripod. "And this will record a simple video of our session so we know what the act normally looks like. It will provide us additional data for any further studies on human behavior during what they refer to as 'making out'."

Once she was done explaining the use of the equipment, she caressed her boyfriend's face and stared into his eyes. "Rest assured, my love, the recording shall remain between the two of us," she spoke with a comforting tone and a smile. "The cameras are all up and running, so we shall begin on your go."

David smiled back. The way she was alluring to him was enough to make him focus on his love for her and ignore her decision to scrutinize their act of romance. "Let's do this!" he proudly stated.

Lisa smirked and slowly guided him to the bed. The couple sat down on it and now that they were in view of the cameras, their session began as Lisa connected her lips to his. Their kiss got deeper as she cupped his face and he wrapped his arms around her torso. They fell back on the bed still making out with Lisa on top. David rubbed her back soothingly while she grasped his hair.

They broke off their kiss to catch their breath as Lisa felt David stroke her back. "Oh, yes..." she moaned softly. "Your hands are perfect for my torso."

David smirked. "I'm glad," he said.

After a moment, Lisa started to gently caress David's chest. It felt pleasurable to him like it was to her.

"That feels pretty spectacular..." he sighed happily.

"This experience will escalate the more we give in to our feelings," Lisa proudly stated.

David always found her smart and nerdy persona attractive and now the attraction was stronger than ever.

Lisa leaned down to kiss him again. First on his lips, then along his face and down to his neck. David took in the affection he was receiving from her for a moment before deciding to take control and give her some affection of his own. He secured his arms around her again and turned them both over. With him on top now, he kissed along her face and reached down to her neck as well.

"You have an extraordinary sense of affection," she commented with a grin.

"And it's for you only my love," he replied before kissing her again.

"Oh, Davey..." she said blissfully. "Only you can generate this emotional state into myself."

"I feel the same about you, beautiful," he replied. "And I won't rest until you've gained complete and utter satisfaction."

He caressed her face in his hands and kissed her again. Soon, Lisa turned them over so she could take control.

"Alright. You've earned a rest," she said. "I shall assume command so you don't tire and we can keep the process functioning."

"Always love hearing you work that brain of yours!" David commented.

The pleasure that was felt between them was still going strong. The young scientist couple kept on showing their affection until they decided they've had their fill. They laid down on the bed to rest for a moment with their arms still around each other.

"That was quite the adventure," David remarked happily.

"A very fascinating experience," Lisa added, also full of content. "I'm pleased to have shared it with you."

They kissed again before getting up.

"And now to document the data," Lisa said as she started to observe her equipment to review the recordings of their session. David realized he was so focused on loving her that he forgot all about the equipment she set up so she could study their love fest. He realized that he wasn't exactly bothered by Lisa's habit of making scientific observations of their activities together instead of just simply enjoying them. Even though he still preferred that she would just enjoy them, it still didn't ruin their time together and he was satisfied with that.

His thoughts were suddenly interrupted by Lisa shouting out in confusion.

"What!? How can this be!?" she exclaimed.

He saw that she was checking her monitors and seemed stunned by something.

"What's the matter?" he asked with concern.

"My devices were unable to collect any data from our session!" she explained. "None of the cameras recorded anything! Each for a different reason, no less! The camera for the body scanner still had the lens cap on, the emotion recognition camera wasn't even turned on, and the iPhone camera was set to face the opposite direction as us! I could've sworn I had everything set up properly by the time you arrived, but I can only assume my desire to become intimate with you had overshadowed my desire to scrutinize our intercourse. What a waste..."

She sat back down on the bed and sighed in disappointment. David, however, was glad about it. He sat down next to his girlfriend and put his arm around her.

"Well I don't think anything was wasted," he said comfortingly. "To me, this proves that our relationship means more to you than scientific research. And that's all that should really matter."

Lisa took a moment to think deeply about it and looked up at her boyfriend, smiling. "You know what? You're absolutely correct, David. I didn't think about collecting any data during our session. I was only focused on allowing us to feel that extraordinary sensation. I didn't realize it, but that was all I cared about."

"It was the same for me as well," David agreed. "I don't really mind if our time together involves research, but our prime objective should be that we genuinely enjoy each other's company more than scrutinizing."

"Couldn't have stated that better, myself," Lisa said proudly. "I guess there is no better scrutiny than the exploration of pure bliss and intimacy between lovers."

They shared another passionate kiss before laying back down for a little nap.

"What do you say we head down to the pool area in a little while before ordering room service and catching that outer space documentary scheduled to air this evening?" Lisa suggested as she rested her head on his shoulder.

"Sounds like a plan," David happily replied. "As long as you don't disinfect the pool this time."

Lisa smirked. "No worries. That'll be for our bathroom shower so we can guarantee cleanliness for us."

The two geniuses fell asleep together with the intention of enjoying the rest of their vacation at the hotel and the certainty that their love for one another meant more to them than any scientific study.

Hope I got Lisa's dialogue pretty good. I must say it was an experience writing her as a grownup being romantic. You don't find that everyday.
