I imagine this story has been written by a sexy redhead with a great big pair of tits and an amazing ass.

I like the story. It made my PP big.

Imagine if Gray also broke in and was just listening outside xD

Cute and sexy story. I'd recommend doing a new paragraph each time you have dialogue from a different speaker, however. Makes it flow more smoothly and is easier to follow. Good job!

I have to agree... this was great!

Definitely amazing.

...That... Was... AMAZING! Please, do more Nalu stories!

...I don't know if you take request/offer/suggestion, but if you do, I got an idea for a Nalu and Gale (maybe even StingYu, Miraxus, Kinabra (Erik x Kinana) and Roguerva):

All the Male Dragon Slayers are going through heat (Dragon Mating Season; like actual Mating Season, it lasts for a whole season) and are ready to mate. However, the Alpha of the group has to start it off before the others could (That being Laxus; all the Dragon Slayers formed a pact with each other, becoming a family group of their own from how few they are [Wendy is their baby/little sister, but is too young for Mating Season]). He starts off by scent-marking his mate, before he takes her to his den, while releasing a pheromone that the other males picked up and went to look for their mates (They find it to be the appropriate time to claim their mates and start families of their own [They want to become fathers and desire to have their mates pregnant with their babies/hatchlings.]).

While the females, not Dragon Slayers, are effected by their mates' pheromones (lightheadedness, fever-like symptoms), which helps their bodies to relax and increase the chances at becoming pregnant. So, the males will keep mating/rutting with their mates, until they end up pregnant... And yes, the Male Dragon Slayers have knots (In some way, they're more dragon than human and should share some properties that a dragon has. Also, because dragons are animals and most animals have knots... Not trying to be creepy, or anything.)
