Warning: NSFW stuff ahead!

Makoto Tachibana had always thought of himself as a decent guy. He would play with stray kittens, help old ladies cross the street, the whole shebang. He recycled, for God's sakes. So maybe, just maybe, God was rewarding him for his kindness, in the form of a cute girl asking to watch porn with him for recreational purposes. Or maybe God was just fucking with him, and if he took up the offer he'd be the devil incarnate...

"Makoto! Did you hear me? I wanna watch... porn. With you." Gou's voice was unsteady, but she enunciated the word porn. Makoto snapped out of thinking hard and blushed hard. Nothing was going as he had expected that day.

"Well, then... I guess we can! Let me just... pull something up..." Gou watched intensely as Makoto opened up a folder on his computer called "Tokyo University Application Essays." The contents certainly did not consist of essays, and both parties began blushing for different reasons.

He has a collection of porn... in a secret folder... Well, I guess it makes sense, he has siblings... But...

She's the first to see my prized, award-winning porn collection... Okay, it's no big deal, but... Well, at least I didn't name it "Shark Week Videos" like Rin. That's too suspicious...

"So, uh, Gou, since you're the... guest, I guess, you can take your pick. They all have... descriptive titles." Makoto looked away, tussling his hair with just a hint of shame.

"Well, let's see... Makoto, what's a 'creampie'? That sounds cool!" Gou's face lit up at the mention of dessert. Makoto stiffened, hurriedly thinking up a response.

"It... it's when, uh... It's when you put... whipped cream... on the other's body..." Makoto couldn't make eye contact with the redhead.

"Really? The thumbnail doesn't look like that. Hmm, that seems kinda intermediate though... Okay, this one says 'amateur'! That means they don't go too far, right? Let's watch this!" The poor, poor brunette was regretting allowing this situation to occur. Gou's innocence rang out with every word she said. Suddenly, she played the video, and...

"...Whoa!" Gou covered her eyes with her hands. They start out with a sex scene? What about the character development!? And... she'd never seen a man's penis before, and it was suddenly thrust in her face... "It's got... veins... it's like another muscle..."

Meanwhile, Makoto was cowering in the corner of the bed. Gou has somehow managed to pick his favorite video out of the bunch, and he wouldn't dare watch it with her. Though, the sound was on pretty loud... Maybe he'd be able to bear it. It was for educational purposes, after all.

Gou blushed as she felt Makoto inch closer. She'd been so absorbed in the movie, that she hadn't even noticed Makoto moving away. So... Makoto has one of those, too... I wonder how big it is... No, no, don't be a pervert! Though, I am watching porn...

"M-maybe, we shouldn't be watching this..." Makoto uttered the words without much conviction. Gou looked over to him, and noticed he was adjusting his clothing, when she realized...

"Makoto, are you... hard?" She covered her mouth after asking the question. So immoral! How could I even ask that!?

"W-wellllllll... a bit, yeah. Not all the way. But uh, I can get rid of it..." Makoto absentmindedly closed his eyes, as if he were thinking deeply.

"No. Wait. Makoto... Don't. Let me see it."

"EH!?" She closed the laptop Makoto was using.

"Think about it! We both have no experience! We'll do better if we learn together. We'll teach each other, and you'll tell me how to do stuff so you like it. Okay?" Gou balled up her fist to show her resolve, though the rest of her body was shaking. Makoto seemed to be letting the idea simmer in his mind.

"I don't know... Are you sure? I mean, I don't mind it, but I don't want to taint you, Gou..." Makoto was letting his angelic side get the best of him yet again.

"Be a little more selfish for once, Makoto!" Gou took the initiative and unzipped his pants, then pulled out it out. "WHOA!" Gou couldn't help but gasp. It was huge. Bigger than the guy in the porno, and certainly bigger than she ever imagined. "And you're telling me... it gets bigger than this!?"

"Sure. You can help out with that. O-only if you want to, though..." Gou couldn't help it. Seeing a penis in real life was fascinating. A little scary, but she definitely wanted to touch it.

"Can you do it yourself a little? So I can see what the proper technique is?" Makoto blushed at the thought of jacking off in front of Gou, but, she had requested it... She stared intently as he moved his hand up and down, and watched his member stick straight up, even larger than before. "O-okay, let me try now..."

Makoto removed his hand, and guided Gou's hand to his erect penis. She slowly began stroking it, her hand shaking a bit... Wow. It feels like skin like any other part of the body, but also, very hard... And it feels hot... Makoto let out a grunt that startled Gou.

"D-did I hurt you!?" Gou nearly screamed, hoping she didn't do anything wrong.

"N-no, you're fine! That means it feels good! But could you get the tip a little more?" Gou let her hand back onto his rock-hard member, and this time focused more on the tip as well as the rest. She let Makoto grunt and groan as much as he liked.

"Could you... spit on it a little? So your hand moves more easily?" Gou couldn't believe such a dirty request. But, at the same time, maybe... she could try something else... even more daring...

Rather than simply letting saliva drip on his penis, she bent her head down, and made sure her hair was out of her face. Gou stuck her tongue out cautiously, and licked the tip a few times, and then put her whole mouth on it. She began to suck his dick graciously, somehow enjoying the feeling of something so hot and hard in her mouth. Wow, I can feel it throbbing a little... It's like, it's really begging for this...

"Mnnng... Gou, are you...!? I mean, I won't complain, but..." The redhead found the task difficult after a bit. She could only fit about half of his large member in her mouth, and her jaw was starting to get tired...

"MMPH!" Gou felt something salty and thick hit her throat. She swallowed it, only realizing what it was after she let it slip down her throat. Oh gosh, I'm so lewd, I swallowed his cum...

Makoto let himself relax a little. Well, I'm certainly satisfied, and she's probably satisfied now, right?

"It's not fair." Gou turned her nose up a bit and looked away from the brunette.

"Eh, what's not fair, Gou...?" Makoto pleaded with her, wondering why she was suddenly angry.

"I... want to know what it feels like to cum, too..." Gou said it in such a small voice, but Makoto hung on to every word.

"Well, I guess it's time to return the favor, Gou." Makoto grabbed Gou by the shoulders, kissing her passionately, which she began to reciprocate. One of his hands move to her back, while the other...

"Mmph, Makoto, where are you planning to touch..." Gou tried to speak through the kissing, but she felt so weak...

"I'll make you cum, Gou, I promise."
