Wait until the next bell

You decide to try to wait until the next bell.

Looking throug the class, you notice that three of the four other pregnant girls from your school are not coming to class. They are probably in labor by now. The only other pregnant girl, Sandy, is sitting just next to you.

Sandy has always been the girl, all the guys were trying to get. But she has never been a real slut, like all the other girls who got pregnant at the party. She is a beautiful young lady, but now her face looks strained as she gently pushes the top of her massive belly.

Since she became visibly pregnant, all the boys have kind of lost interest in her, but you have been watching her closely. It seems that here belly shape changed since the last time you saw here. She has always been rather slim, and the enormous belly laying in her lap looks really out of proportion. Her C-cup breasts are resting on top of the massive bulge and are nearly bursting out of her white top, where a small wet point has appeared right above the right nipple. Nobody else seems to have noticed, not even Sandy.

Sitting on your chair, the baby presses against your bladder. It is impossible you are going to last two hours without going to the toilet. You gently rub your belly, which feels really hard right now. You can feel a gentle kick from your baby which is followed by a small contraction. You lean back in your chair, as you wait for the contraction to end.

The teacher starts explaining the assignment for the next two hours. During his explanations, your eyes wander to Sandy, who seems as if she was really in pain. Even though the teacher is speaking quite loudly, you can here her groan and small drops of sweat are running on here face. Then it gets quite in the class as everyone starts working on their assignments. Only the sound of pencils scraping the paper disturb the silence. Occasionally, a heavy breath of Sandy goes through the room, but nobody except you notices.

During the next hour, you try to work on your assignment but your focus is either on Sandy, who is moving nervously on her chair, or on your own contractions, that seem to have gone from fake to real. There were four contractions of increasing intensity so far, but Sandy is at about 10, as far as you can say. Her legs are spread to let space for the huge belly resting between them. Her top has lifted and is now revealing her bellybutton. The waistband of her gray yoga pants is still wrapped tightly around her big belly. She is leaning back in her chair and one hand is sqeezed under her belly, exploring the area between her legs. The patch on her right nipple has widened, and a small one has formed on her left breast as well.

Suddenly, she turns to you and whispers: "Can you please help me and follow me to the toilet?".
