Peter 3 shook his head. “Me neither.”

“Oh.” Peter felt his face heat up, something the bite hadn’t been able to stop from happening. “Well, forget I said something.”

“No, wait, this is interesting.” Peter 2 straightened where he was sitting against the wall. “We seem to share most things, but not all. Why’s that?”

The rooftop was chilly, the sun having hidden behind the city and the wind having replaced its presence. They’d been refusing to move, finding peace in Peter’s haven, but he suddenly felt a timidness wash over him that he hadn’t felt in a while, and the secludedness of the place didn’t help. It felt intimate, in a way; something you shared with friends. The other Peters were definitely his friends, but he was reminded of how little they actually knew about each other.

He tried to keep his gaze at them, but the way Peter 3’s lips curved upward, the way Peter 2 was still observing him as if he was the most interesting thing in the world, made his courage fail him and he had to avert his gaze.

They didn’t know what he liked. They weren’t Ned or MJ, who would know to not tease him without actually tickling him. This was worse. This was innocence and curiosity mixed together, and Peter wasn’t sure his face wouldn’t give him away.

“I don’t know,” he said. “Up until now I didn’t know other Spider-Men existed.”

“Fair enough.”

“Wait, wait,” Peter 3 suddenly said. “How ticklish were you before?”

“Uh.”

“Oh, you’re blushing.” His grin when Peter looked back, so easy to coax out of him, made an appearance. “That’s cute, but that’s nothing to be embarrassed about.”

“I can’t help it,” Peter groaned, covering his face as Peter 3 laughed.

“I take it that you were quite ticklish,” Peter 2 said. “That could explain it.”

“Wait, how ticklish is ten times as ticklish?”

“Please stop.” Peter held up his hands. “Or I’m going to literally die right here.”

“That’d be a bit annoying, wouldn’t it?” But Peter 3 leaned back, a visible retreat. “I’ll make sure to add that to my list of what I know of you. Number three: don’t tease Peter about how ticklish he is.”

“What are the other two?” Peter 2 asked, so casual about all of this that Peter felt dizzy.

“Well, number one is that he’s apparently also Peter Parker.” Peter 3’s grin melted into a smirk. “And number two is that he’s apparently very ticklish.”

“Oh, come on.”

“I feel like number four should be what your proper laugh sounds like.”

Peter didn’t move even when they both scooted closer to him, sitting cross-legged on both of his sides. “Please forget I said anything.”

“Oh, but this is a scientific experiment,” Peter 3 said. “We gotta find out why you’re apparently ten times as ticklish.”

“I just have a question,” Peter 2 said. “How often do you get tickled to find this out in the first place?”

“Uh.”

“Often?”

Peter covered his face again. “Quite often I guess.”

“Okay, that’s all I needed to know. You know, for science.”

Peter 3 grabbed his knee. “For science,” he said and squeezed.

It was all a bit of a blur after that.

Peter’s laughter was quick to pour out of his mouth. That much he knew. At some point he fell to the side and Peter 2’s surprisingly nimble fingers decided to attack his lower back, which made him squeal. Peter 3 wouldn’t let that sound go, once they were done with him.

But before that there was Peter squirming without getting away, his knees rising without breaking the cross-legged position, and his hands flailing without protecting him much. He could hear the other two cooing, laughing, maybe teasing, between his giggles, and while he knew he would never live this down he also kind of enjoyed it all the same.

“It’s safe to say we should keep this a secret from bad guys,” Peter 2 said once they’d let him breathe freely again, grinning down at his curled up body on the roof. “And try to keep you from getting another spider bite because I’m not sure your body would handle getting more sensitive.”

Peter groaned. “Please stop.”

Peter 3 poked his leg. “Hey, at least I can add a fifth thing to my list now. Doesn’t fight back.”

Peter sighed and rolled over onto his back. It was nearly entirely dark now, the sky littered with stars. His only witnesses. “I’m not gonna say it.”
