I'm not generally a fan of stories where the characters are this young, but I like your writing so decided to give it a read. While the sex is not subtle, you have established that there's more going on here than just the physical. The connection between Marty and Jesse may appear to be hormones, but I think there's more going on underneath the surface. I'm wondering why Jesse's dad wants 'the fort' taken down though...from your description I'm picturing it in the back of the property, concealed by woods. But maybe I got it wrong. Regardless, I don't think it's going anywhere anytime soon. lol
