You and your girlfriend sat in your seats (you sat next to each other in the middle of the classroom) from where you attended the class. At first it seemed that nothing different would happen in class, but you realized that it would not be as easy as you imagined a few minutes after the beginning of class you looked at your girlfriend. She had her legs spread and her skirt was slightly lifted with her stroking slowly.
You leaned over and whispered to your girlfriend "I can't believe you already have a hard-on again. You came just now."
"I know I know. But this is not easy, I'm not used to it yet and what I felt when I came was so good that I can't get it out of my head." she whispered back to you
"Please try to hold on until the end of the class, as we may have another quickie." you whispered
"I'll try, but I can't guarantee that I'll make it." she whispered
That said, you looked around hoping that no one noticed what your girlfriend was doing. Those who were sitting in front of you obviously hadn't noticed since no one looked back, looking at your opposite side to what your girlfriend was sitting on, you saw that the boy who sat there had not noticed anything but seeing the girl who sat behind him you were surprised by what you saw. This girl was a little bent and when paying more attention you noticed that the tip of her dick was coming out of the collar of her blouse and she was kissing it. You were surprised that not only was she hard, but her cock was probably bigger than your girlfriend's. She noticed you looking at her and sat up, pulling her collar up, which covered the tip of her cock but it wasn't enough to hide the erection that went up inside her shirt.
Then you looked back at your girlfriend and saw that she couldn't resist and was slowly stroking her dick through her skirt again. Then you looked at the whole class paying attention mainly to the girls and realized that they all had their dicks hard and were kind of masturbating on the sly. As you looked you saw that some had their dicks lifting their skirts, going down the leg of their pants or facing upwards inside their shirts, but without exception they all had a huge dick, all about the same size as your girlfriend.
You called your girlfriend who answered quietly "Sorry, I tried to stop touching my dick but I can't help it."
"I know, but that's not why I called you. Take a good look around, you are not the only one in this situation." you said
Your girlfriend was surprised by what you said and looked around, seeing what you had seen earlier in the other girls. Then she leaned over again and said "It is true. And look at the size of their cocks, I thought mine was easily the biggest but it looks like I'm average here at the school."
"I also noticed that there is one more thing that is strange. If it was just you or two girls, they would probably go unnoticed as long as you don't come, but with all of them doing it I don't know how our teacher hasn't yet seen what's going on. You know how hard it is to hide something from her." you said
"Now that you mention it I find it strange too. See, she hasn't written anything on the whiteboard so far and just reads what's in the book with her back to the class, only her voice is very low, I can't really hear what she says." your girlfreind said
You looked at the teacher and realized you also thought she was acting differently, so you got up and went to her to tell you that you couldn't hear what she was saying. As soon as you put your hand on her shoulder to get her attention, she, who hadn't noticed you approaching, got scared and jumped around and looked at you. When she did that, not only you, but the whole class, could see what she was doing. The zipper of her pants was open and she had her hard cock fully exposed, while she held the book she read with one hand she held her member with the other.
Your teacher looked from you to the rest of the class, put the book on the table and said to the whole class "I'm sorry for that. The school policy allowing only sticks was extended to the teachers and I had to go through the procedure too, but I'm not used to it yet. Please do not report me or I will lose my job. I am a single mother and I depend on my work here to support a small child."
"You are a very selfish teacher. Here I am suffering so that you don't realize that I was having problems with my erection and you there jerking off in front of everyone." The girl you had seen kissing the tip of her cock before stood up saying disgusted, then one by one the other girls stood up taking her side in the revolt, your girlfriend too.
"Sorry, I thought I was the one with the problem. It didn't cross my mind that you were going through the same." the teacher said
After that there was a minute of silence until everyone laughed, then your girlfriend said to everyone "We are really in an unusual situation, but we cannot stay like this, we will not be able to concentrate on the class. What are we going to do to solve the problem?"
"It seems that we have no choice, we have to satisfy ourselves sexually. Come on girls, we can't get the classroom dirty and a bathroom would be small for all of us, so let's go to the locker room." the teacher said
They all agreed and soon the teacher and 15 more girls left their seats and left the room, then his girlfriend took your arm saying "Don't just stand there looking, you come with me."
"No, he won't. He's a guy and only girls should go." A girl who saw this said to you
"Of course not. The bathrooms and locker rooms are not even more divided into male and female, not to mention that he is my boyfriend and I want him to go with us." your girlfriend replied
The girl was going to try to argue, but the teacher came in saying "She's right, we can't leave the boys behind like that." then she turned to the others and said "Alright guys, those who want can come with us." With that you were able to go to the locker room with them.
Aside from you, three more boys went along while the others stayed in the room saying they were going to study, but they were boys you already knew were against the school policy that forced the girls to have a dick instead of a vagina. When you arrived at the locker room, your teacher instructed everyone to remove their clothes and put them in the cupboards to avoid getting them dirty, since they didn't know how it would look with all of them there. You and your girlfriend did it without any problems, but some girls were a little afraid due to the boys' presence, taking a little longer to undress.
With everything ready, each one found his own corner where everyone jerked off. You watched while jacking off the bunch of girls and your teacher playing with their own dicks, all of them with huge dicks that were 15 to 18 inches long.
It didn't take long for your girlfriend to make you suck your dick by saying "You can stop it. I want you to use this to fuck my ass."
"Here with everyone watching? Don't you want to leave it for a moment when we are alone?" you asked
"I don't wanna wait, I want you to fuck me here and now." your girlfriend said
You then complied with her request and penetrated her asshole. So it seems to have had an effect on others who saw it, because they started to jerk off more willingly. Soon after, yout girlfriend placed her cock between her own breasts and titfucked herself while sucking on the tip of her own cock. Seeing this, some girls stopped just wanking to repeat what she did and others even joined in pairs to suck each other's dick.
In a few minutes girls started to cum one after another. The dressing room quickly became white with the cum that flew everywhere, including the others that were part of the orgy that had formed in the locker room.
It took a while for everyone to finish their orgasms, as clearly the girls' fucking production capacity was far superior to that of the boys. Once finished and all of them with their flabby sticks, they saw that they had all soiled themselves with the others' seeds, so they all took the opportunity to take a shower before going back to the classroom, taking care to avoid the cum puddles they got on the floor, which was very difficult.
