Oral sex, of course!

"Now we're going to move onto blowjobs, or ‘suckjobs’ as you called them earlier," Kae announced.

“Oh, right, the lesson.” Komaru said, a little embarrassed as she climbed out of Shuichi’s lap and left a noticeable wet spot on his underwear. “I-I think I’m ready!"

“Good! Now, it’s okay if we take these off, right?” Kae asked with her hands on Shuichi’s grey boxer briefs. The black-haired boy nodded and she pulled his underwear down, allowing his hard cock to flop free out into the open air.

“Oh! So, this is what a real one looks like?” Komaru knelt in front of Shuichi and brought her face close to the throbbing pole to get a better look. “It’s a lot… veinier than I expected.”

“Every penis is a little bit different, but you’ll find that most of them are like that,” Kae replied. “Now then, to give a man a proper blowjob, you need to be very careful. Sticking it inside your mouth is easy enough, but treating it gently takes skill. You’ll need to wrap your lips over your teeth to help make sure you don’t accidentally scrape him and aim carefully so he doesn’t hit the roof of your mouth too hard. You’ll also need to suppress your gag reflex if you plan on taking him into your throat, which can be very hard to do.”

“Alright… I’ll try my best.” Komaru stared at Shuichi’s dick in fear for a few moments before giving his dick an experimental lick. He was very salty, but the taste wasn’t too unpleasant, so she followed it up with another lick.

“Yes, that’s it! Get used to the taste!” Kae encouraged as the brunette slowly lathered Shuichi’s cock with her spit. “It’ll help make taking it deeper inside easier.”

Komaru kept licking from base to tip for a few minutes, Shuichi’s cock twitching whenever her tongue flicked off the tip. Eventually, Komaru gained enough confidence to take the tip of his dick into her mouth. Shuichi let out a few gasps as he felt some of teeth collide with his sensitive cockhead, but that was quickly replaced by the feeling of her tongue swirling around it. She attacked Shuichi’s tip lick it was a lollipop, licking it from every angle to try and make him feel good.

Komaru’s eyes glanced up nervously at Shuichi, part of her expecting him to be upset for some reason, but she was relieved to find him groaning in pleasure. Growing bold, the novice escort began to bob her head up and down, taking Shuichi’s length farther with every thrust of her head. She could tell by the way he groaned and the way his dick twitched that he was feeling even better, which egged her on to **** him inside ever further. Suddenly, she took a deep breath and shoved herself down as far as she could, bottoming his dick out in her mouth and throat and allowing her lips to kiss his groin for a brief moment. But, as amazing as it felt to Shuichi to stretch Komaru’s throat like that, she gagged almost immediately and pulled his dick coughing and sputtering.

“Oh god! That… that hurt!” Komaru gasped, grasping at her throat. “How do girls in AVs make it look so easy!?”

“Yeah, it’s actually a skill that takes a lot of practice. I’m not surprised you couldn’t take it all in on your first try.” Kae placed a comforting hand on Komaru’s shoulder. “But remember, you need to set your own pace, not your client, and that’s true for when you’re practicing too. If you’re not careful, you can seriously hurt yourself, and trust me when I say you don’t want to have to go to the emergency room for sucking someone’s cock.”

“Wait… has that actually happened to you before?” Komaru asked curiously.

“Th-that’s beside the point,” Kae said defensively. “The point is, you’ll learn to deepthroat eventually, but even if you don’t most boys will be satisfied if you just use your mouth. Isn’t that right, Shuichi?”

“Yeah… your mouth feels amazing, Komaru!” Shuichi gasped to her.

“Alright… I guess I’ll keep going then.” Her breath now recaptured, Komaru took Shuichi’s dick back into her mouth, but this time stopped just before it reached the entrance to her throat. This left most of Shuichi’s dick out in the open air, but that mean she could focus more on what was inside her mouth.

She swirled her tongue around his shaft as her lips formed a tight seal around it that would squeeze periodically around the middle of his dick as she licked. She slowly began to move her head up and down like before, but her movements were much longer and deliberate this time. It was almost as if she was savoring the taste of cock, but he knew she was just being careful.

“Yes, there we go! Now you’re getting into it!” Kae said encouragingly. “Oh, and try to look him in the eye while you do it too, that’s a turn-on for most men.”

Komaru looked up at Shuichi and he did his best to look back without flinching. The look on her face was more curious than lustful, though, as she studied the way his face contorted with every movement her mouth made. She was amazed by how she could make him squirm with the just the smallest licks, and she idly wondered what a real pro could make a boy do with a cock in her mouth.

“Mwa…” After two minutes of sucking, Komaru abruptly popped Shuichi’s dick back out of her mouth, letting her spit to drip out onto his shaft and her chin in the process. “Sorry, Shuichi, I just… wasn’t expecting to drool that much.”

“Oh, you don’t have to worry about keeping it inside like that. Boys usually like having a little slobber on them, especially if its from a cute girl!” Kae advised. “Plus, spit can be used as lube for all kinds of fun activities~”

Kae gripped her own breasts through her tight sweater vest and winked at Komaru.

“Oh, you mean like paizuri?” Komaru asked. “Is it okay if I try that now?”

“Sure, go right ahead!” Kae replied. “And see if you can keep licking him while you’re at it! It’s a little hard to multitask like that, but I know you can do it! I believe in you, Komaru!”

Komaru smiled and removed her shirt and tie, allowing her breasts to finally bounce free of their confines. They were about average size for a girl of her height with bright pink nipples that Shuichi couldn’t help but stare at. They were also very soft too, as Shuichi discovered as Komaru pressed his dick in between them.

“Just like that, Komaru! You’re doing great!” Kae cheered as Shuichi’s throbbing tip poked out from between Komaru’s tits. “Now, knead your breasts together, and bend your neck down to lick his tip. It might make your neck a little sore, but it’s one of the most powerful techniques in any escort’s book.”

“You mean, like this?” Komaru pressed her breasts together around Shuichi’s cock and immersed it in ocean of soft marshmallow pleasure. His dick throbbed hard between her tits as he felt her soft skin, slickened by her spit, rub against it. As she moved her beasts together, Komaru extended her tongue from her mouth to continue her tongue bath, lathering it in even more drool.

“Exactly like that, Komaru!” Kae said with a smile as she noticed Shuichi’s balls start to really tighten. “Now if you’ll excuse me, I’m going to go find some tissues. We might need them for this next part.”

“If you say so,” Komaru said before returning to her titjob.

Komaru kept going for several more minutes, pleasing Shuichi with her soft breasts and warm, slick tongue as best as she could as Kae watched on with an approving smile. Shuichi, meanwhile, could do nothing but sit there and gasp as he hurtled towards his first orgasm of the day.

“Komaru, I… I think I’m going to cum!” Shuichi warned as his pleasure began to reach its peak.

“Okay, now it’s time for a very important decision, Komaru,” Kae interjected. “Do you want take his cum inside your mouth, or outside?”

“Uh… inside, I guess?” Komaru took the tip of Shuichi’s dick back into her mouth and swirled her tongue furiously to push Shuichi over the edge. She didn’t have to wait long before she felt the first rope of white goo was **** into her mouth, coating her tongue with its taste. That shot was followed by another and then another, until her mouth was so full that her cheeks were bulging. By the time Shuichi had finally finished unloading inside her mouth it felt to her like she had a whole half gallon of spunk was stuffed inside around her tongue.

“Aaah… that was amazing, Komaru. Thank you so much.” Shuichi let out a sigh of relief as his afterglow slowly wore off, but he soon noticed that Komaru was looking up at him with a very strange look in her eyes. “Uh, Komaru? Is something wrong?”

“Mmmm… mmm…” Komaru mumbled as she took her mouth off Shuichi’s dick. “Mmmm… bleeeeh!”

Komaru grabbed the handful of the tissues Kae had ready and spat into them, coating them in a mixture of her spit and Shuichi’s thick semen.

“Oh my god! That… was so gross! Ew ew ewwwww!” Komaru kept spitting into Kae’s tissues to try and get as much of Shuichi’s sperm out as she could. “I thought that stuff was supposed to taste good!”

“I’m sorry, Komaru, but semen is a bit of an acquired taste,” Kae explained apologetically. “Most women don’t actually like it, but pretending that you do is a great way to make a man feel special and powerful. The same goes double for swallowing it, but that can be even harder than deepthroating. I would have told you earlier, but I was afraid that might psych you out.”

“You expect me to swallow that stuff!?” Komaru asked in shock.

“No no, of course not! You don’t have to do anything you don’t want to!” Kae replied hastily. “I’m just pointing out the reality of your new job. The more you enjoy, or at least pretend to enjoy, semen and the more you swallow it, the more customers you’re likely to get and the more they’ll be willing to pay for your time.”

“Hmmmgh…” Komaru glanced back towards Shuichi’s cock and noticed that there was a wayward strand of cum still sticking to it. Trembling a little, Komaru brought her face back towards Shuichi’s dick and licked up the entire strand before swallowing and then reopening her mouth to show that her tongue was now clean. “Thank you so much for your delicious cum, sir.”

“Y-you’re welcome,” Shuichi replied, still slightly aroused even though he knew it the compliment was fake.

“Oh my goodness, Komaru! You’re so brave!” Kae smiled wide and pulled into a strong hug. “I’m proud of you! You’re well on your way to being an excellent sex worker, I can tell already!”

“Heheh, thanks, that means a lot to me!” Komaru said with an embarrassed blush. “Can we move on from the oral lesson now, though? My jaw is starting to get sore.”

“Right, of course! But before we do that, I need to ask you a very important question.” Kae let Komaru go and looked the younger girl in the eye. “Are you on any kind of birth control right now?”
