Muscle Envy

Summary: Sometimes, Izaya really envied Shizuo's muscular body.

Rating: K+ for an angry Shizuo and tricky Izaya…

Pairings: Shizuo/Izaya in an established relationship

This drabble is more funny! I wondered if Izaya was ever jealous of how much bigger Shizuo looks compared to him and this scene popped into my head. XD Enjoy everyone!

Sometimes, it really sucked being scrawny.

Izaya frowned as he glared at his reflection in the mirror. His pale face stared back at him, his crimson eyes trailing down to scrutinize his thin torso. He splayed his fingers against his stomach, touching it and feeling its firmness but seeing there was no obvious muscle definition. He was fit but not muscular, and at the moment, that bothered him.

Normally, he had no problems with how he looked—believing he was forever fabulous. But sometimes he wished he were a tad bigger.

After all, he was always active! He was a parkour master and forever outrunning that monster, Heiwajima Shizuo. Shouldn't he have bulked up even just a little because of that?

Izaya turned towards the bathroom door as it clicked open, the aforementioned monster yawning and scratching his stomach as he walked inside. Izaya pointedly watched as Shizuo pulled off his shirt and threw it into a laundry hamper, grabbing a towel off the rack to hang up next to the shower.

The raven watched with sour expression as the muscles of Shizuo's back flexed with his movements. Shizuo wasn't overly muscular—which was a good thing because Izaya found men with too much muscle just unnatural—but it was obvious that the blonde was toned. His arms were much stronger looking than Izaya's thin ones, and Shizuo's torso was at least two inches ticker than his. And where Izaya's stomach was simply flat and firm, Shizuo had the definition of solid abs.

Izaya had to admit he had a bit of muscle envy as he narrowed his eyes at Shizuo's robust, unblemished, tanned back.

Sometimes, life just wasn't fair.

Shizuo frowned midway in his preparing for his shower as he felt a slight itching sensation on his back. He reached back, growing alarmed when he felt rough scratches on his back. Turning his head completely, he saw Izaya waltz out of the bathroom innocently. Narrowing his eyes in suspicion, but finding nothing out of the ordinary, Shizuo turned back to take his shower. Except his reflection in the mirror caught his eye.

"IIIIIZZZZAAAAYYYAAAAAA!"

The raven smirked as he imagined how red Shizuo's face must be at seeing the word "Idiot" scratched into his back. But Shizuo only had himself to blame.

After all, it was his fault for having such a muscular body.

But we all know that Izaya still likes to have Shizuo's muscular body on top of him. X3

Thanks for reading and reviewing!
