Since the viewers for my English story is more than my Indonesian story, so I will write story in English. Actually this is the next chapter of 'Sex Education for Conan'. But because the language is different, I make it into new story.

I'm so sorry if my grammar is not good, I'm still junior high school student

Sex from Ai

It seems that Conan really needs sex. After got it from Ran, now he will get it from Ai.

The story happens a day after story 'Sex Education for Conan' where Ran wanted to teach Conan sex education, after get mocked by Sonoko. Conan which peeping when Sonoko have sex with a guy in the beach was turned on, he applied what he had seen to Ran, of course with naive kid style which pretended not to know anything. Surprisingly, Ran was enjoyed by Conan's play. But Conan was not satisfied having sex in that small body, he even be tired easily before Ran get her climax. So now Conan which can't hold his sex desire anymore really needs to be Shinichi. Just a day after returning from his trip to Okinawa, he went to professor's house.

Conan ran to Prof. Agasa's house. The car was missing but door was not locked, maybe professor forget to lock the door, or Ai was inside. He then entered the house and walked to Ai's room. Just when he wanted to knock the door, a moan was heard.

"Ahh, ahh, ahh..."

'Could it be Ai? What is she doing there?' Conan kept listening behind the door, he enjoyed the moaning from Ai, and it made his cock harden. He grip it, it has been so long since the last time he masturbate. In Conan's form, he never did it anymore. But he really wanted to do it now. He does fap fap. Unconsciously he releases a moan too.

"Who's that?!" cried Ai. Conan was shocked. Suddenly the door opened.

"Since when you standing there Kudo?!" Ai's face was red and full of sweat.

"Ng, ng" Conan can't answer even though actually he wanted to say I hear you masturbating, I enjoyed it and I do masturbating too

"Did you hear me?" asked Ai again.

"Since when did you do that? I never heard Ran did something like that" answered Conan, full of shy but his curiosity is more than his shy.

"Ahahahah, I'm not same with your innocent girlfriend, my life is hard, and sex is just a snack in my life in black organization" answered Ai calmly.

Gulp. Conan was just startled by the little girl in front of him.

"Okay just forget about that. So what the hell bring you here?" asked Ai just like there is nothing happen before.

Conan then remembered his main purpose to come here.

"Ai! I have an important request, please, I really need the antidote now, please, it is so urgent"

"Hey, you look like a drug addict craving for drugs. Tell me what is that so-urgent-thing which makes you need the antidote so bad?"

"I, I can't tell you, it's privacy" Conan was blushing

"Hmm, what is the thing which more privacy than your true identity? I guess it's about the girl in Detective Agency. What happen to her now? Did she get new boyfriend?"

"Oh no, no, it's something I can't tell to you"

"Hmm, okay, I will give it, but in one condition."

"What's that? I will give anything to you"

"Anything? Well, since you've heard and disturbed my masturbation, you have to serve me. Beside, I don't believe that an amateur like you could serve that girl, better I teach you how to serve woman."

"Ng, ng, are you serious? Then give it now, we won't do it in this form right"

"I don't want to drink that incomplete medicine, if only you drink it I don't want to have sex with a pedophilia, so better like this"

"You call me pedophilia? Huh, do you think I want to have sex with flat boobs girl?"

"Well, if you don't want it's okay, you also can't have sex with that big boobs girl in detective agency. Everything needs sacrifice, Kudo"

"Okay, okay. But how do you know that I want to have sex with Ran?"

"What is another thing which is privacy to me if not that thing? Now shut up" then Ai put her lip on Conan's lip. Ai tried to ask for excuse to get inside Conan's mouth, but Conan kept close his mouth and eyes.

"What do you want to do to that girl if you kissing like a kid?!"

"Um, sorry, I haven't do it before"

"So you give your first kiss to me? Lucky me. Now follow me" Ai kiss Conan gently, she put her tongue inside him and play with his tongue. There was a romantic feeling inside her heart. She kisses Conan's cheek, down to the neck, while her hand unbuttoned Conan's shirt. She licked Conan's nipple, while her hand unzipped Conan's pant. She kept kissing his body downward, until she arrives at his penis. Conan's penis had hardened, she grip it with her hand and shake it.

"Uaahh, that's gooood" She lick it to make it wet, and then put that small penis inside her small mouth. She sucked with his penis just like lollipop, in and out, slowly at first, then became faster and faster. She did the blowjob in perfect pressure and tempo, enough to bring lots of enjoyment without hurting, even not a single of her teeth touch his penis. Conan moans a lot.

"Ah, ah, ah, Aiii, faaster... I'm commming… Ahhhh" Conan releases his juice in her mouth. Ai drinks it all and clean Conan penis by her tongue and mouth.

"Where did you learn that?"

"I told you, penis was my daily snack in black organization. Now it's your turn to serve me"

Conan open Ai's blouse, then he saw Ai's still flat breast. He sucked her left nipple while another hand grip and plays her right nipple. Ai moans, shows that she is enjoying that. Conan then moves its mouth to her right nipple. After get bored on nipple, he opened Ai's skirt. There was only her underwear which is look wet from the outside.

"Ow, you're so wet. Do you want me play inside you?" said Conan while rubbing his finger from outside the panty, make Ai opened his leg and moaned.

"Uhh, uhh, please do it Shinichi, fuck it hard! It craves for you!"

Conan then opened her panty. Now they both were fully naked. Conan rub Ai's vagina slowly, then he opened her leg, showing her small and pink vagina to him. He put his mouth nearer, smelling the scent of her vagina. He then licks his vagina, and sucked her clitoris slowly. Made Ai moaned so hard.

"Oh, umm... Well actually I don't have it right now, but I will make it special for you"

"So what's all of those things mean?" Conan was a little angry

"I am so sorry." replied Ai sadly

"Don't be sad, I enjoyed that thing too"

"Really? I'm sorry to fool you Kudo. As soon as the antidote finish I will call you, so you can have fun with that girl"

"Hey Shinichi, you're here. Hey, why are you both sweaty? What are you doing?" asked Prof. Agasa suddenly.
