Getting a second opinion

What Greg said and showed Jack about the student athletes' regular orgies weighed on him for the rest of the day. Jack liked to think he knew his way around_ _a lover as well as anybody, but his group experiences were... limited. He'd always been a shy kid, and crowds overwhelmed him pretty quickly.

Would sweet, cute Stacy really expect him to keep up with that? He had fucked her plenty of times one-on-one, and she always seemed to enjoy it. Was she just being polite? But that kiss! The way she held him! That had to mean something, right? And why would she have given him her number if she wasn't interested?

Jack's sister, Jeanie, had been a volleyball player before she graduated last year; if these parties were a thing, surely she would have heard of them. And maybe she'd heard a thing or two about Stacey, too.

He found her in the living room, riding a handsome guy Jack didn't know and watching some game show.

"Mmm... Hey, Jacky! How was school?"

"Oh," Jack sighed, slinging his backpack off and sitting in the recliner, "the usual. Who's your friend?"

"Friend?" Jeanie frowned for a moment, genuinely confused, before remembering that the dick in her pussy was attached to an actual person. "Oh, this guy? I dunno; just saw his cock in the bathroom at work and decided to bring him home with me. Wanna borrow him when I'm done?"

"Nah, I'm good. A little too nervous to fuck, actually. Do you remember Stacey Owen?"

Jeanie closed her eyes to think, slowing down her gyrations to clear up some RAM in her head. "Cheerleader, right? Natural blonde, c-cup, occasional squirter. I think she might've had a thing for you, you know."

"Well, she did give me her number today..."

"Awww, little Jacky's got his first girlfriend! They grow up so fast." Jeanie reached a fist out to Jack, which he duly bumped. "So what's the problem?"

"Problem? Who said there was a problem?"

Jeanie silently cocked an eyebrow.

"Okay," Jack admitted, "there's a problem. But could we talk about it in private?"

"Sure thing, just give me a minute or two to finish up with what's his face here."

Jack kicked his feet up and fucked around on his phone while his sister went from casually riding to fucking in earnest. She found a steady pace, rubbing her clit with one hand as she bounced in his lap. Her other hand started out groping her large tits before sliding down her stomach, then reaching around to spank her own jiggling ass. It wasn't long at all before her face and chest flushed, her breathing hitched, and every muscle in her body spasmed with pleasure. Jeanie came long and hard, falling back against the stranger's chest to catch her breath for a while.

"Damn," Jack shook his head. "That looked like a good one."

"I really needed that," Jeanie gasped, climbing off of the stranger's still hard and quite impressive rod. "You can see yourself out?"

Jack scoffed; "Really? You drag him all the way home with you, tease him for who knows how long, and don't even let him cum for his trouble?"

"Come on, Jacky. Like you take to time to make everybody cum when you use them?"

"At least I try!"

"Try, then," Jeanie shrugged. "I'm done with him; he's all yours."
