The Beast Within

Description-
Mark and Jack are in their Junior year of high school. They aren't exactly friends. Jack knows Mark and Mark knows Jack. They've had classes together before and they have classes together now. It's not that they don't like each other, it's just that they've never had a reason to hang out.
Until they are assigned partners for science class. They see no problem with working together. One day when they're at Jack's house though something is different. There's a scent in the air. To Mark it's enticing. It smells incredible to him.
Then Mark realizes that the smell is coming from Jack. Jack's an omega. Jack is in heat. Jack's in his first heat. And Mark is an uncontrollable alpha.

So this is a Alpha/Omega septiplier story. I don't know everything about this topic but I've read other stories like this. It's not the best description but it'll get the idea across. Enjoy!
