Peeping Tom!
Disclaimer~Hiro Mashima's work, not mine.

Igneel stood at the door of his son's room, from outside he could hear two teens studying perfectly...or so he thought.

"Natsu don't be so rough..." He heard the feminine voice of Lucy Heartfellia.

It did make Igneel a tiny bit curious when Lucy had earlier appeared at the door of his home and asked if the two of them could study for an up and coming physics test.

"Sorry...can you pass me the spare?" Spare what?

"Here..."

He heard Natsu hum in approval, "thanks that's better, you're the best Luce, always prepared," prepared? Are they doing something that needs preparation?

Igneel pressed his ear to the door, his red hair rubbing against the wood.

"Wait further to the left..." this was followed by an elicit moan, definitely a feminine one.

"Yep...right there," are they really doing what Igneel thinks they're doing?

"Natsu I can't, my shoulder is killing me."

Igneel felt slightly perverted for his actions but he felt slightly proud.

Especially reeling in a pretty fish like Lucy, but aren't they moving a little to fast? But Igneel was overwhelmed he didn't think Natsu would never get involved with a girl, he isn't a bright light bulb, maybe even the dimmest. You know what, Natsu is the light bulb that never turns on, no matter how hard you try.

"Go straight, stop making this difficult," wait my son is sloppy? Should I give him pointers? Maybe even a book with positions.

"Hey Natsu watch out!" He heard Lucy yelp, Igneel was ready to burst in but he we was unsure of how much he can handle seeing his son scandalously holing a rich young woman, who may or may not be dressed inappropriately.

"Sorry, you're soaked..." Igneel blushed.

Maybe he should be at least a little proud of his son.

"It's okay, calm down just watch where you're going next time, go slower-" wow, this Lucy sounds experienced.

"We should probably clean up, before dad comes in..."

"Yeah, but before that, you know you did really good...like exceptionally well, it's my first time doing this but it worked out well-can we do it again...?" Igneel was getting prouder by the second, he must be good.

So after that they're going to stay together?

"Maybe tomorrow?" Igneel didn't remember having that kind of energy when he was younger...in fact Igneel was pretty sure he was still interested in play fighting with his old friend Metalicana back then-but it seems Natsu is advanced already.

"Can't I have plans with Cana but maybe I can come later...when your dad isn't home? I'm pretty sure we can both finish up next time."

Igneel felt like he should go and brag to Metalicana about his son's achievement, that brawny teen of his isn't going as fast as Igneel's is. But he did overhear about that incident with Gajeel and a certain Librarian...

Igneel cringed.

Because of his distracting thoughts Igneel wasn't able to hear what his sons reaponse.

But he heard Lucy's.

"Yeah! That sounds great I know a few people that would love to join..."

Does Natsu realise what could happen if they add a few more people.

Igneel knew for sure that Natsu would be heartbroken.

Privacy is important in a relationship.

Without a second thought Igneel burst through the door, and then he wished he hadn't.

There sat Natsu casually lounging on the bed whilst Lucy was at Natsu's desk scribbling on a piece of paper...don't even try kid, I know this is a cover up I bet she was all over you a second ago-Igneel mentally growled.

"Uhh hey Pops, what's up?"

Igneel flushed red, clearly embarrassed, but he began to imagine what face he would make if Lucy and Natsu were both naked doing exactly what Igneel had thought they were.

"Nothing, absolutely nothing I was just wondering what you two were doing?"

"Study," yeah...right and I'm actually a dragon!

"Okay then, can I see your progress?"

"Of course Mr Dragneel," Lucy said cheerfully, handing him her paper.

He looked over her work...it looked fine.

"And you Natsu?" Natsu's head was tilted down.

"Can't..." He grumbled looking ashamed.

"Why?"

Oh and here the truth comes.

"Because..." Natsu took a deep breath, "I was too rough and kept breaking holes through the graph paper."

Wait.

Lucy didn't allow Igneel the chance to decipher his thoughts, "yeah, we nearly ran out of spare paper, because of that and the fact he can't plot the points on a graph, he always put them to the right."

Natsu snapped his neck in her direction, while Igneel was frozen like a solid rock.

Is that the spare something they were talking about?

"At least I got the straight line right."

Igneel is far more obtuse than he thought.

"After I helped you by holding the ruler in that awkward position, I told you my shoulder was killing me."

Igneel shifted his eyes between the two while thinking, wait I thought-

Suddenly Lucy stood growing exceedingly irritated with Natsu, and upon her stance Igneel spotted a damp part on her jacket like water had been tipped on her.

The light bulb lit in Igneel's head, 'you're soaked' oh.

"Natsu you're the one that wanted to do study together I told you it is my first time doing this at least appreciate my help," Natsu sighed.

"I'm sorry Luce, I did enjoy today though, I just want it to be the two of us, I don't like the idea of Cana interfering she'd be drunk by the time we get to the porch considering she's sober at the start of the driveway," oh my niece? An alcoholic at eighteen...

So this was just another misunderstanding! Without warning Igneel fainted due to the overwhelming issues he seems to have with his son, and one thought was in his mind.

This kid is going to put me in retirement forty years to early!
