Pleasurable, with some answers soon after

After the customary squeeze of Alexis’ breast, and her quick fondle of his manhood, it was finally happening. Josh decided to be a gentleman and go first. He wasn’t sure if that was the official protocol, but he wanted to make a good first impression. As he fell to his knees, with the party still raging around him, Alexis used both hands to pull down her short shorts, revealing dark red panties, before those were on the floor too, and her well-shaved snatch was visible for everyone to see.

The best view in the house, of course, belonged to Josh. She was slightly wet already; he wondered if that was from him or from previous encounters earlier in the night. Looking up, he saw Alexis smiling down at him. “Hurry up, slowpoke,” she joked.

After what was surely seconds but felt like hours, Josh leaned in, stuck his tongue out, and made one long, slow lick up Alexis’ slit. He felt and saw her shiver slightly, clearly aroused by Josh’s ministrations. Like with Adam, after a few seconds of pleasure, she pulled back. I guess you don’t do it enough to orgasm, Josh thought. He enjoyed the taste of her in that brief time, however, and silently prayed it wouldn’t be the last time.

Then, the moment he’d been waiting for since he learned about the new rule and Alexis’ attendance at the party. They swapped positions, and the brunette quickly tied her long hair behind her head. She was unfazed by Josh’s fully erect penis when it emerged from his undergarments, and went to work.

For those few beats, Josh was in heaven. His secret crush was sucking his dick beautifully, and right out in the open with dozens of people standing around, none of them giving a hoot. The juxtaposition of it all had him close to bursting, when Alexis removed his dick from her mouth with a light, satisfying pop, and rose to her feet.

“Always fun, Josh,” she said with a grin. Alexis was about to walk away when he stopped her with a hand on her shoulder. “Wait, hold up,” he said, zipping his shorts back up with the other hand. “I need to ask you something.”

“Sorry, I promised Jordan I’d be right with him,” Alexis said apologetically, and she moved off into the crowd.

“I can tell you like her,” came a female voice from behind. Whipping around, Josh came face-to-face with Kate, another fellow senior, but more of what you’d call a “nerd.” Even in this modern nerd-driven culture, she was more there: he’d heard Kate talk about Star Wars shows he hadn’t even heard of, and he was a fan of the IP.

A beat after an exchange of crotch grabs, Josh was about to say something but hesitated. When Kate didn’t act, he figured that they weren’t supposed to have oral sex with each other. And that made sense: he knew Kate, certainly, but he never considered her a friend.

Finally replying to her initial comment, Josh began: “No I’m not-“

“Yes, you do,” said the dark-haired senior. “Don’t bullshit me, I can tell. And why not, she’s hot.”

He was a little thrown off by that remark, since he knew Kate had a boyfriend, but he quickly realized that in a world where everyone had to swing both ways, so to speak, to keep their friends pleasured, there was nothing odd in her making that comment. Striving to change the subject, Josh figured he’d ask Kate what he wanted to ask Alexis. This would take some finagling, though.

“Hey Kate,” he started, “I need some help. Pretend for a second that I’m some sort of alien, and I have no idea about human society. If I asked you why we…um…go down on our friends, if you will, how would you explain it?”

That was a dumb way to try and get his own question answered without sounding like a crazy person, Josh knew, but it was worth a shot. And Kate was odd enough that she might answer him straight-up.

“Oh, interesting,” she said, her eyes lighting up. “I love hypotheticals.” You’re weird, but thanks, Josh thought. “So, I think a lot of sociologists would say that it started because our orgasms feel so damn good that our ancestors wanted to share that feeling with our friends. And that makes the most sense right?”

Josh nodded, pretending to understand. “But if that’s the case,” he offered, “why don’t we pleasure each other to completion today?”

“That’s easy,” Kate replied, brushing a strand of hair out of her eye. “It’s messy. If I had to take a shot of cum every time I blew a friend during the day, I’d look like a porn star. So instead, starting in the early modern era, most societies that we know of just went to the level of orgasm with their very best friends, or on special occasions.” She finished with a smile, clearly proud of her knowledge.

“That sounds right to me,” Josh lied. “I just, uh, saw that hypothetical online, and figured you’d be a good person to ask.”

“You know it,” Kate said. “I spent a few weeks this summer deep diving on the history of that stuff. Anyway, I gotta get some more punch. Be back.” And she was off. He made a mental note to keep Kate in mind if he wanted to learn more about this new world.

Having successfully bullshitted his way through that conversation - and getting some valuable background knowledge to boot - Josh pulled out his phone and checked the reality timer app. He had a shade under eight hours remaining on the current countdown. That would run out while he was asleep, he realized. So Josh pondered his options: he could simply enjoy the party and do something with the app afterwards, or he could make a change now and observe it take effect in real time. He knew he had to choose quickly; there were likely a few more dicks to suck and pussies to taste around the room before long.
