A/N: Based off of Episode 10: Mad Mod. Or rather, after it all. Heavy lime with no lemon.

Starfire was in the middle of brushing her red hair, a couple of days after taking down Mad Mod. As she brushed, she heard a knock on her door. She stood up and opened the door to see Robin, whom was holding a package. She instantly smiled.

"Hello, Friend Robin. Is there something you need?" Starfire asked her visitor.

"I have a package for you." Robin showed her. She tried looking in but it was filled with paper blocking her view.

"Is it a gift?"

"Yes. From me to you." He answered. Starfire gasped in delight.

"Oh thank you Robin." She thanked so gratefully. "What is inside the bag of gift?" Robin smirked as he put it down and closed the door behind him.

"That can wait. For now I just want to..." He didn't finish as he kissed Starfire on the lips, catching her by surprise. It only lasted a moment though as she returned the kiss while also wrapping her arms around him in a hug, bringing him close. Feeling her bust press into his chest, he grinned as he got out of the hug and kiss, confusing Starfire until he picked her up, making her yelp in surprise as he took the alien girl to her bed and laid each other down on it, with the Boy Wonder underneath the Tamaranian warrior. He turned her head to continue kissing her while his hands went to her 'grebnacks' to massage them. Starfire now knew what he wanted, and took joy that Robin wanted her. She broke the kiss to look down to her chest, seeing that he started to grip his hands around them, squeezing them like one would squeeze a sponge to get the water out. While his grip wasn't strong or too hurtful, she could feel the pressure as the fat tissue was being compressed thanks to her leader's hands. As Robin moved them around, Starfire saw her nipples getting hard from the massaging, so she assisted him by using her hands to pinch her nipples. This made her start breathing heavy as even though the 'grebnack' itself isn't something that brings about arousal, the nubs at the end sure do if subjected to enough pressure.

"How does this feel Star?" He asked her in a turned on tone.

"Oh, very much so, Robin." She answered with the most sincere grin. "While your massaging techniques are mildly enjoyable, I am loving that you wanted to share this moment with me."

"Well, I know how we can make this even better." He suggested.

"How can it?" She inquired, curious.

"That's what the stuff in the bag is for. May you please get up?"

"Of course." She obliged as she got off of Robin and the two approached the bag. Robin took out the obscuring paper and presented her clothes.

"Clothes? I thank you but what are these for? These are not the superhero clothes." She pointed out.

"Well, have you heard of cosplay?"

"No."

"Well, cosplay is to wear clothes for the sake of pretend. And when you asked if all schools were as bad as Mad Mod's place, I thought I'd show you the general gist. Some things won't be accurate, but that's just for right now in this circumstance. Questions?"

"Why do people do this cosplay pretend?" Starfire asked.

"A few reasons. One is for recreational fun, one is for conventions for one particular things, and the third reason, which is the reason that we're doing, is for sexual pleasure and immersion."

"Oh, I understand." The Tamaranian nodded.

"Great, so here's your clothes. I have my own so that it's not just you, and its fair." Robin stated as he handed her the girls clothes. "Uh... Star? Are you okay with me changing in here or do I have to change in your closet or my room?" The Boy Wonder asked, wanting to be considerate.

"I don't mind. You can change in here." She nonchalantly answered. To prove it, she took off her gloves before tacking off her two top pieces, showing off her bare upper torso. There were visible tan lines that showed a lighter shade of orange compared to her constantly shown skin, and her hardened nipples were a dark vermillion color. Robin's pants just got tighter in between his legs.

"O-ok then." He muttered as he proceeded to remove his shirt and pants while Starfire removed her shirt and thigh high boots. The only piece of clothing they had left were yellow trousers and purple panties. With no problem they put on their socks and respective tan khaki shorts and bellowing knee length blue skirt.

"Oh I just love how much this article moves around as so." Starfire appreciated as she floated in the air and spun around like a ballerina, causing her skirt to flow outwards into nearly a cone shape. He hair also swished with the direction of her spin. But the most attention grabbing was her breasts, due to inertia, was going outward, especially filling out at the ends so that they looked particularly thin around the base. Robin was too distracted to put on his shirt until she stopped spinning and picked up her shirt. That was where trouble started arising for them, but only Starfire looked upset.

"Come on little button. Please go into the hole." She politely told the button as she tried closing the shirt at the full swell of her Grebnacks, but she just couldn't get it in there without damaging the shirt with her strength. "Robin, I think there has been a mistake in your order. This shirt is too small."

"Oh, there is no mistake. I ordered them too small to begin with. Look at me." He requested. Starfire looked to her leader only for her blush to deepen quite a lot with the fact that his shirt was barely containing his lean yet well-toned and muscular body.

"Oh holy X'Hal." Realizing what he said, Starfire shook her head and questioned, "Wait, why did you get them small deliberately?"

"It's part of sexual cosplay, wearing clothes that are too tight. Men can wear shirts that are a bit small. It's just tight and ill-fitting. But women, they have a much harder time as even tops with buttons and zippers that fit them can't fit over the breasts."

"Than how can I properly partake in the cosplay?"

"It's a bit of a struggle but there is a trick to it. Let me show you." Robin offered as he got behind her. "So, the first thing is to button all of these above the swell of your chest." He then helped her with getting all the buttons into the right holes. "Then we pull down." He instructed as the two titans pulled the buttons over her grebnacks, having to put some effort since her chest was quite flattened due to the small size. By the time they got it fully down her upper body, it was just barely able to reach her skirt, showing off her lower belly, and Starfire's chest was squished against her ribcage, also leaving gaps in between the buttons.

"It is a bit difficult to breathe." Starfire complained as she pressed her hands into her grebnacks, only able to push them a little bit further.

"And that's one of the parts of sexy cosplay. Please hold out a little bit, but when you think you need to, just breathe out or jump and they will pop right off.

"Will that not damage it?"

"I don't mind. They can be mended." Robin reassured her.

"Okay. I trust you." She said, attempting to smile.

"Thank you. Now, please take a seat on your bed. Now begins the real part of this cosplay." Robin took a piece of machinery out of his belt and threw it on the ground. It produced a hologram that said 'Human Sexuality 101'. "Now just to be clear, most of this is just for pretend purposes, but I do want to show you the general gist of what a school is. Understood?"

"Yes, I understand." She nodded.

"Good. Starfire, do you know how your race interact in sexual activity?"

"No. My mother, father, and Galfore have not explicitly told me about that. I just know that Tamarans have two stages of..." She paused to think of the right word. "...puberty."

"Two?"

"Yes. The first one is for physical growth, and the second one is for sexual growth and fertility." She explained.

"Interesting. Well, humans have only one stage, and can begin as early as 10 and ends at 18 Earth years old. It has growth for both humans such as size and mental maturity, but there are some things specific for humans. For women, there is your grebnacks, or breasts that arouse men. You know that much. You want to know what physical arousal does to men?"

"What?" The Tamaranian princess asked, curious.

"It makes the their dicks get excited. Here's what they look like." Unzipping his pants, he brought out his 6 inch hard penis. Starfire's blush deepened from seeing it.

"A... dick. I think I've heard a few people called by the name of dick." She told her leader.

"For some, it's their name. For jerks, it's an insult. Why it came around, I don't know. It's a nickname for the name Richard." He explained.

"May I touch it?"

"Sure. It'll do good to be familiar with it." Robin reasoned. Starfire brought her hands to his penis and poked it, making it twitch. She leaned back slightly, almost afraid of hurting it. The princess then took a light hold, feeling it up.

"It feels hot."

"When it becomes aroused, it fills with blood."

"What do I do now?" She asked her instructor.

"Now this is something called foreplay, which is the act of sexual activity. Step 1. Lick it. You don't have to if you don't want to though, if you wish. I won't force you to do anything."

"I don't mind. Thank you though." Starfire shook her head before sticking her violet tongue out to lick it. And again to reaffirm the flavor. "Hmm. Salty."

"I just worked out before coming to see you." Robin replied.

"It tastes good." She said before taking the whole thing into her mouth. The Boy Wonder nearly buckled to his knees not expecting the whole thing to be blowed. She bobbed her head back and forth.

("Her whole mouth is wrapping me. Damn. This is amazing, and so literally hot! It's like my dick is melting.") Robin thought to himself. After about a couple of minutes, he could barely contain himself. "Starfire, something is about... to come out of them. Take it out please." The warrior looked confused as she took it out.

"Why do you-?" She didn't get to finish though as the room temperature air pushed it over the edge as Robin came onto her face, spraying his white essence all over her orange face. She yelped from the surprise squirting.

"Wha, why did it do that? This feels... strange." The Tamaranian princess commented. Robin tried answering in between huffs while he sat down next to her.

"That was my... penis doing something called... ejaculation. It's when... men reach peak arousal and... release our semen. It's the stuff... that makes Earth babies. And yes, it can feel... very hot initially." He remarked. After licking all of it off her face, her smile came back.

"Hmm. Along with tasting extra salty, I can tell a hint of spiciness." She observed from the taste.

"Must be all the pizzas." Robin reasoned.

"Is there anything else from this sexuality of the humans?" She asked curious.

"You want to continue?" He asked.

"Yes. You are still hard from the looks of it." Starfire pointed at his groin. He looked down to see his dick didn't go flaccid.

"So it seems. Well, I guess the next thing to do is a boob job." Robin chose as he stood up.

"Boob job?"

"Yes. It's when the dick is placed in between the breasts."

"Oh, so does that mean I can take this shirt off?"

"Actually, I have an idea." Robin said, grinning. He managed to stand up, put his hands on the alien princess's shoulders, and lightly pushed her down onto her back. Taking off his shorts, the Boy Wonder climbed up on the bed and mounted in her midsection. "Now here's where the fun part comes in." The titan leader whispered into her ear before pressing his hands down onto her 'grebnacks' and wormed his penis into a gaping whole in between the buttons and started pushing back and forth in her cleavage.

"Ooh, the pressure feels so good. Your hot dick feels nice rubbing in between them." Starfire moaned, liking the experience. Due to how tight the shirt was, the constant rubbing popped the buttons off, freeing her bust. "Ah, that feels better." She sighed with content as she took a couple of deep breaths.

"Star, would you like to continue this for me?" Her leader asked the Tamaranian warrior.

"Alright." Starfire nodded as she took hold of her grebnacks and rubbed them up and down on his shaft. "How do you like it when I do this?

"It feels so good." Robin gasped, loving how new this experience was for him. "Starfire, you're so hot. This feels really nice." He complimented his comrade.

"This feels that good? Then I will put more effort to pleasing you." She told her leader determined with a smile as she squeezed hard on her bosom, putting a lot of pressure on the dick in her cleavage. "Robin, how much do you like my grebnacks?"

"A-A whole lot." The Boy Wonder gasped.

"I like it a lot too. It feels good feeling its heat rub against them." She said, loving how much her charms were working so well. Robin started going full throttle as he pumped back and forth. Starfire noticed how close his penis was and decided to do more as she took it into her mouth, wrapping her tongue around it. This was too much. He couldn't take it anymore and came into her mouth, which was being gulped down by the alien girl. After sucking it all up, she panted from the extended lack of air. "So sticky. Yet such a delectable taste." Starfire giggled as she smacked her lips. Robin panted as he rolled to his side and breathed heavily recovering his energy. Starfire came to his side and laid her head on his shoulder. "So, how was that?"

"That was... amazing." Robin answered.

"I am glad. That was a good lesson." She giggled again.

"It was."
