i really like this and i love the way it's written but omg please change the bit about zack's "seed". that's a word that should never be used in this context :L
I've never read this kink before so it was interesting. Good interesting tho. And I found the bit about Jack getting his dick stuck in the door pretty funny
This is the first time I've read this pairing, and I sort of love it. There is not enough Zack slash on the internet. I love this one shot! Please write more if this pairing :):)
