It started innocently.

Honestly.

During the game of Mario Kart, Sam had made a comment that prompted Blaine to poke him in the ribs. Nothing too odd about that…except for the way his entire body twitched.

A few days later, they'd been sprawled on the couch, watching a movie, and Blaine lazily reached across Sam to grab a handful of popcorn. Accidentally, his fingers dragged across Sam's taut belly. The blonde practically convulsed, jerking away from Blaine's hand, an odd noise caught in his throat.

Surprised, Blaine pulled back. "Are you ticklish, Sam?"

There was a tiny pause before he replied with a firm, "No."

The pause was enough to tell brain that yes, Sam was very ticklish.

On Saturday, they were again on Blaine's couch, heads at opposite ends and legs tangled together, Star Trek XI on the big screen. Neither one of them was really sure when their bromance had shifted into this nebulous, not entirely platonic quasi-dating, but it had, enough so that, a few weeks earlier, Sam had made a point to offhandedly informed Blaine that he was bisexual.

Just a little FYI.

So it wasn't weird when Blaine let one of his hands land on Sam's ankle, rubbing lightly. Sam gave him a quick smile and wiggled his toes contentedly.

Feeling a little impish, Blaine got a firmer grip on Sam's leg and then wiggled the fingers of his free hand along the high arch presented to him.

Sam's reaction was instantaneous. He yelped and jerked his leg away, hauling Blaine along with it.

Their eyes met and Blaine grinned wickedly, twisting his body and laying down the top Sam's legs, giving himself access to Sam's feet and attacking both. Shifting his legs and wriggling, Sam kept making strained, huffing sounds, obviously trying not to laugh. "Stop…Not…Funny!"

"It really is," Blaine countered and, had Sam been able to coerce his limbs into some semblance of coordination, Blaine was pretty sure he would have already been thrown onto the floor. As it was, Sam only drew a shuddering breath before breaking out into loud, involuntary laughter. His hands clamped down on Blaine's own calves as he rapidly dissolved into a gasping puddle of hysteria.

A somewhat aroused puddle of hysteria, as Blaine could feel Sam's cock, half hard and pushing up against his leg as the taller boy writhed beneath him.

Eventually, he decided to show mercy and eased up, allowing Sam to calm down. Blaine looked over her shoulder and smirked at how red Sam's face was. "You do realize you're never winning a wrestling match again, right?"

Still panting, Sam shrugged. "If I get your hands first, pin them down above your head, I'll be safe."

That idea had an appeal all its own.
