Moving a couple of years ahead now. After the exam, I saw Suzy for some time until she moved away. Since then, I have had several sex partners and have had a good time with them.

Then, after about three years, I get a call from Jacob, asking if I wanted to drop by at school.

I meet him and Lisa in their normal office.

"Hey, John, good to see you again!" Jacob welcomes me, and Lisa gives me a little kiss.

"How did it go after you left school? Did our lessons help you?"

I tell them a bit about the experiences I had with Suzy and with other girls. Also, about a sex party we had some time ago, with 3 girls and 5 other boys, which was good fun.

"I would have loved to join in," Lisa admits, looking at Jacob.

"Do you like being with more than one guy at the same time?" I ask, surprising myself.

"Yes, I love a good spit-roast," Lisa replies with a smile, "and even a DP now and then."

Then we get to the serious bit.

"As you know, we have some trainers to teach the students. Suzy did teach you a lot, and you were a good student. Now, one of our male trainers has stopped, so we have an opening for a new trainer. We look for students who did well in class and gained some experience after that, and based on your stories, you did," Jacob explains.

Lisa now takes over. "Next to the experience, there is also the physical aspect. You really look nice, not very muscular, but just good. Also, and that is something I always take note of during the exams, you pack a nice size down there, not too small or big." I feel that I start to flush a bit, but Lisa ignores that. "We need trainers that do not scare the girls in any way, and I don’t think you will."

Then Jacob continues. "There are, of course, some advantages. You can give girls their first sexual experience, and as you also noticed, that can continue after the lessons stop. But usually there are also some parties with all the trainers and us, and as you have already had something like that, I don’t think you will skip that."

"So, what do you think? Would it be something for you?" Lisa asks.

I give it a little thought. It was something I thought about in the past in an abstract way, but not really what I would do. But it looks like something I could try.

"Yes, I think I would like to try this for one year, and then we can see if I like it," I answer.

"Great, we'd love to have you on the team," Jacob welcomes me, and Lisa smiles.

"Now, a question on your sexual performance: did you ever use the blue pills?" Jacob asks, with a serious face.

I never tried one of these, I tell them.

"It might be good to test them before the lessons start, as we advise the male trainers to use them, so they can stay hard longer and perform several times during the lessons," he explains, as he hands me a packet of pills. "Try one the next time you have sex, just to see if you don’t have any negative side effects."

*****

About two months later, I get invited to the first lesson where the trainers are required. We get in early for some instructions and to see which student we are going to help.

We are shown some photos of the students, and I notice one girl who lives just across the street. That is too close, so I select one I don’t know. It looks like this girl is not as slim as the other girls and also looks a bit shy. Then we get the instructions for the first lesson from Jacob, and Lisa is instructing the girls at the same time.

"During the first lessons, there is no sex allowed; it is just to get the girls accustomed to sex and to you. So you can have them touch you, and you can touch them as well. See if you can give them a first orgasm; that would be nice. Also, something you can do is give them a first taste of cum. Don’t cum in their mouths yet, but give them a nice cover."

Then we move to the back of the classroom, as Jacob and Lisa are getting the students.

As the students enter, they look surprised, just like we did. I see the girl I am going to help, and when the students are at their desks, we all move to our students.

"Hi, I am John, and I will help you during this class," I introduce myself to her.

"Oh, eh, I am Amy," she says softly.

Then Jacob gives his introduction about what is expected: no sex, just exploring and getting to know each other. Then we move to the small rooms. Amy is following me, looking a bit helpless.

When we have the door locked, I sit down on the bed and motion for her to sit next to me.

"How did you like this course until now?" I ask her.

"I don’t know; it is a bit overwhelming, I guess. They are showing things I never saw before, and to be honest, I am a bit afraid of what is going to happen," she tells me softly.

"So was I at first when I took this class, and that is quite natural. I will go as fast or as slow as you like, and you can always say what you think or want. I will never be offended by that," I tell her.

"Now, how about we explore each other? Did you get the chance to touch Jacob in the first lesson?"

She nods. "Yes, I did, and I was a bit scared. When he was soft, it was OK, but when he was hard, it looked so big." Then she looks at me; until that moment, she was looking down. "But I guess that is the reason we are here, to explore. Do you also want to see me then?"

"I'd love to, but only if you want to. You look like a really beautiful girl, and there is nothing to be ashamed of," I try to reassure her. "You know, we were allowed to select the girl we wanted to help, and you were my first choice. You look so nice and beautiful."

Amy turns slightly red from my comments, but does not turn away.

"Now, let me undress myself so you can take a look and feel," I tell Amy as I get up and start to undress.

She looks with her mouth open as I take off all my clothes and stand naked in front of her. I am fully hard, so my dick is pointing upwards.

"If you want, you can touch me anywhere," I tell her. Slowly, she gets up with her eyes locked on my hard dick.

"It looks so big; that is never going to fit in me!" she says, afraid.

"Your body is very flexible, and I will make sure that when we get to that, you are ready for it," I say with a smile. "Now do you want to touch it?"

She carefully moves her hand towards it and puts it around it. This makes my dick jump a bit, which scares her.

"Don’t worry, that is just a normal reaction; this area is very sensitive."

Then she takes it again and slowly slides her hand up and down.

"It feels so soft but still hard; it is so strange." She smiles a bit now. "I guess I should show myself as well then."

She starts to undress. She is wearing an oversized jumper and trousers, and underneath, some very standard underwear.

"Shall I help you with that?" I offer, and she turns around so I can unclasp her bra. Then she turns around, her arms in front of her breasts, keeping her bra up.

Then she slowly lets her arms slide down, revealing her breasts, but she is also turning bright red in the face as if she were ashamed of it. Her breasts are quite large for an 18-year-old girl, but they also look nice and firm, and they stand up nicely.

"Oh wow, you have some beautiful breasts; they look so nice!" I try to convince her. This makes her smile, and she drops her bra on the floor.

Next, she moves her panties down. As she stands up, I can see that she shaved her pussy. She has a full body, but full in the right way. I can see why that made her unsure, as it is not what all those thin models look like, but she looks like a real girl.

"Oh, you look so gorgeous, really good!" I tell her, smiling. "Do you mind if I touch you?"

"Eh, no, I guess," she says, and I let my hands slowly slide over her breasts. As I lightly pull her nipples, I can hear a sigh escaping her lips.

"They feel so soft; I would love to lick them. Is that OK?"

She nods, and I start to lick her boobs and then put my lips around her nipple and suck softly.

"Oh wow, that feels amazing. That feels really good," she says.

"If you lie down on the bed, I can make you even better," I tell her as I softly push her onto the bed.

I lean over her and continue to lick and suck her boobs. Then her hand finds my hard dick, which is hanging down, and she starts to slowly move her hand up and down. After a few minutes, I feel that I am getting close.

"That feels good, you doing that." I lift and look at her. "What did you think when Jacob came during the class?"

"I don’t know, it looked quite hot," Amy responds, "and Lisa seems to like it."

"Would you like to see and feel how that is?" I ask her. "You got me already quite ready for it."

It looks like she wants to as she moves her hand quicker. I now move up on my knees and over her belly, pointing my dick at her boobs.

"Let me give you your first cum," I tell her as I start to jerk quickly.

Then I explode, and the first burst is all over her left boob, and the next one on the other one. The next couple of spurts, I try to divide between the two, until I have just a couple of drips falling on her belly.

"Ahhh, that felt good. How did that look?" I ask, panting a bit.

"Amazing, it came out with such speed. And so much!" She looks really surprised. Then she slides her finger through a blob and tastes it. "Hmm, strange taste, but I think I might like it," she says, as she takes another swipe.

I now bend forward and kiss her. "So glad you like it. I might have some more for you later. But first, let me give you something as well."

Another kiss, and then I slowly move down her body. First kissing her neck, then kissing her boobs and licking them a bit clean, before sliding down.

She keeps her legs together, but as I push a bit, she opens her legs, and I move between them.

I start to kiss around her pussy and let my fingers touch the outside of her lips. She keeps her hands close to my head, so she can control me if I do something she does not like. But the moment my tongue starts to touch her lips, I hear her inhale deeply.

I move my tongue slowly between her lips, and then slide one finger slowly inside her. Her clit is quite small and hidden, so it is difficult to touch, but when I manage to touch it with my tongue, I can feel her hands on my head, not to move it away, but pushing even closer.

I start to move my finger in and out and continue to tickle her clit, and I can hear her start to moan loudly. When I move my finger around to touch her G-spot, she almost jumps underneath me.

"Oh, John, please don’t stop, don’t stop, this feels so good! Please go on!" she almost yells. She starts to move underneath me, so it is difficult to keep my lips on her.

As she quiets down after some time, I carefully move away from her and move next to her. She is still panting, and her boobs rise and fall quickly.

After some time, as she calms down, I ask her, "How was that? Did you like it?"

"Oh yes, that was amazing. I never experienced anything like that before!" I can see some tears in her eyes. "I did try it myself and had some small orgasms, but this was so much bigger; it was so good."

"Thanks, I am glad I was able to do that for you," I say with a smile.

Then the door opens a bit, and Lisa looks around as Amy quickly puts her arms around herself, covering her boobs and pussy. "Ah, it looks like you two get along fine. Don’t worry, Amy, only I can open the door. 15 more minutes, and then you should be back in the classroom again". Then the door is closed.

"I think we should get up then. Let me clean you a bit; you can stay for a moment," I tell her as I get up and get a wet cloth to clean the remainder of the cum from her body. Then I hand her the bra and panties so she can get dressed.

I also get dressed and then wait until she is ready. When we came in, she looked a bit reserved, but now she has a broad smile. Just in time, we return to the classroom, where Lisa asks if everything went well.

No problems were reported, and the students left.

The instructors stay behind a bit, and one of the girls reports that it was very difficult to get a boy to work with her. Lisa promises to assist her in the next lesson.

****

The next week, the instructions are almost the same, so no sex, but this time the girls are allowed to suck dick and, if they want, can receive a load in their mouth. And we are instructed to stimulate their G-spot and give them a good orgasm. I think I was a bit ahead of the program, as we already did that.

We are already allowed into the rooms as the students receive a short lesson. I am already sitting on the bed wearing only shorts as Amy enters and shuts the door. This time she is wearing something sexy, a short dress which shows some cleavage as well. That is already progress!

I get up and kiss her.

"Welcome back, I am glad to see you again! You look good!" I say, smiling.

"So am I, and I went shopping this week for some nice clothes. I have been thinking about last week a lot, and it was so good. Do you think we can do that again?"

I get over to her and kiss her. "Sure, but maybe you want to taste something more from last week?"

I start to slide her dress down and drop it on the floor. She is not wearing the white underwear from last week, but she also has some new lingerie.

"That looks so good on you!" I say as I drop my shorts and my hard dick springs free. "You can see what you do to me. You look so hot. Do you want to play with it?"

"Ah, yes, sure, but how?" She looks at me, question marks in her eyes.

"Well, you could lick it and maybe suck it, as Lisa did in class," I tell her. "But I would drop your bra and panties first; they might get dirty otherwise."

She quickly drops her lingerie and then sits on her knees, looking at my dick. Then she takes it with one hand and starts to lick it like it is a lolly. But then moves her lips around it and starts to suck it in.

"Hmm, yes, that feels good. Your lips feel so good around it, oh yes", I moan. "Now, what you can do to make it even better," Amy stops and looks up at me, " is take the balls in your hand and slowly massage them while you continue to suck."

She follows my instructions, but a bit too well. "Not that hard; they are very sensitive, just very lightly. Ah, yes, that is better!"

I can now feel the pressure build. "Ok, Amy, I am going to cum, I will cum on your boobs again."

She lets go, and I grab my dick, and almost immediately I start shooting spurts of cum. The first one is aimed very badly and hits her directly on her face, but the next ones land on her boobs.

"I am sorry about that," I say, smiling as I grab a small towel and clean her face.

She smiles at me. "You almost shot into my mouth, and it tastes great."

"There are still some drops coming out; you can lick them if you want," I tell her, and she puts her lips on my dick again and quickly cleans my dick.

I pull her up and lead her to the bed. "Let’s see if I can repeat last week."

I quickly start to work on her pussy, and with my finger, I manage to tickle her G-spot, and my lips suck on her clit. Within a couple of minutes, she has another great orgasm. But this time I am not letting go; I continue and give her two more right after each other.

Now I move next to her again and let her regain her breath. As she has recovered, she looks down and sees that I am hard again.

"Hm, you know, can you cum again? But this time into my mouth? I want to feel how it is if you cum in my mouth and really taste it."

"If that is what you want, yes, I can do that," I tell her as I get off the bed. She follows me and kneels in front of me.

"It might take a bit more time this time. Something you might want to try is how far you can get it in."

Then she puts her lips around my dick and starts to suck hard on the top. Her teeth are softly scratching as she moves her lips to the base. Then I can feel the head touching her throat; she moves her head back.

She lets go and looks at me. "How was that? Was that deep enough?"

"We could try to go deeper. I will hold your head and slowly push further. You just put up your hand if you get uncomfortable."

She nods and takes me back into her mouth. The moment I feel her throat, I take her head and push further. When I am completely in, I wait just a moment, and then she puts up her hand. I quickly pull back.

"How was that? That is what is called deepthroat," I tell her. "You were able to do it very well."

"I was afraid I was not able to breathe anymore, but it did feel OK," she tells me.

"Well, you just need some more training, but for now it was enough. You know what it is. And guys really like it if you can suck them so deep," I smile at her. "Are you ready to get your next load, because I am almost there. You still want it in your mouth?"

"Yes, I want to," she tells me, as she takes me back into her mouth.

I grab her head and start to fuck her mouth with quick strikes.

"Oh yes, there it cums!" I warn her, and I was just in time as I start to blow cum into her mouth. She takes it really well, and when I pull out, she shows me the complete load before swallowing it.

"That was really good of you. You are a quick learner. But let’s get dressed again, as we are running out of time."

When we are both dressed again, I grab something I was hiding for her. It is a large dildo.

"Here, this is for you. The next lesson is in a couple of weeks, and then we will go even further. With this, you can already start to understand how it feels inside you. And you can use it for condom training, as that will be part of the exams as well." I hand her the dildo and grab some condoms and a small bottle of lubricant from the shelf to go with it.

Then we return to the classroom, and a couple of minutes later, the lesson is over.
