Holly, then Rose.

"Me!" said Holly. Within a second she was on top of David, straddling his waist.

"Hey, why do you get to go first again?" said Rose.

"Don't complain, you've got someone keeping you going," said Holly while she lined up her pussy with the tip of David's huge cock. She had to kneel with her pussy a foot over him to get in position.

Emma tried to pull back and say something, but Rose pulled her head hard forward and squeezed her thighs shut, locking Emma against her pussy.

"Yeah, you're right. The house elf can work on me until it's my turn."

Emma licked diligently. The twins hadn't called her a "house elf" since high school. She'd never been sure if it was a little affectionate or a lot mean.

As it was, Emma was actually a little relieved that she didn't have to go first. Having only been able to fit the tip of David's cock in her mouth, she was a little worried it would split her in two.

"Ooooohhhhh my godddd it's so goooooood!" said Holly as she slowly slid down on David's big cock. She stopped halfway down and leaned forward, letting him lick her nipples. She leaned forward a little more so her big breasts were on either side of his face and twisted, slapping his cheeks with her tits. When she caught her breath again, she pushed herself the rest of the way down with a loud moan.

Despite Holly being on top, David still did most of the work. He put his hands under her thighs and easily lifted her up and down. Every thrust made Holly shriek a little in a high pitch, which sent chills through Emma as she thought about what it must be like to get rammed like that.

After a couple minutes, David said, "Okay, you have to do at least a little bit of the work!"

Holly laughed, out of breath. "Yeah, okay. I'm so wet now, it shouldn't be a problem."

She began riding his shaft without his help. David took the chance to lean to the side and kiss Rose. He reached out and cupped the large breast of the twin who was riding him with one hand while he groped the other twin's perfect breast with his other hand.

Meanwhile, Emma licked Rose's clit as hard as she could and jilled her cunny with a free hand. She came for the first time of the night listening to Holly scream with delight through her own orgasm. It was the fastest Emma had cum in years, maybe ever.

Rose spread her legs to release Emma and swung a leg over her. Emma looked up to see David was rolling an exhausted Holly off of himself and standing up. Rose went over to a large table and bent over it. David stood, lightly stroking his massive rod, and walked towards her.

"Hey, Emma," said Holly with a lazy, delighted smile on her face. "How about you come over here and clean this huge-dick splooge out of me? I promise you the cum from a dick this big tastes incredible!"

Emma looked over at David and watched as he lined up his cockhead with the pussy that Rose was kindly spreading for him. His cock truly looked like a beast. She watched as he shoved it in the beautiful girl.

"Oh, yeah, that's right!" shouted Rose. "Ram that hog in my little cunny! Give me what I want!"

It was too much for Emma. If only to hide from the overwhelming show, she scooted between Holly's legs and began eating her out again. She could taste the difference, he'd definitely cum inside of her, and it did taste great. So how was he hard again for Rose already?! Were big cocks that much better than what she'd been getting?

"Yeah, fuck! Fuck! Fuck! Give it to me harder! Your big cock feels so good!" yelled Rose.

Emma kept licking. Holly didn't seem to be getting close to another orgasm, but she did stroke Emma's hair and purr as the petite girl ate her out.

"Oh my god, that's so good!" yelled Rose. "I'm cumming! Are you cumming?!"

"Yeah, soon," said David. He held her wide hips tight and pushed into her even faster. "Where do you want it?"

"Just... a... sec!" Rose squeezed her eyes closed and let out a huge string of profanity as she came. Then she pulled off David and knelt before him. "Shoot it on my tits!"

"Oh, hell yeah!" David jerked his massive cock in front of her. A huge rope of cum came out on her big, D-cup tits. She smiled and rubbed it into her flawless skin.

"Wheh! That was fun!" said David. "Hey, do you all mind if we move this into the bedroom? I need a break."

"No problem," said Holly, pushing Emma away and getting up. "Emma, would you mind bringing the joint and the lighter?"

"Oh, and grabbing some drinks from the fridge?" added Rose.

"Sure, no problem!" said Emma.

By the time she got to the bedroom, the other three were already sprawled across the bed. The room was lit by a single, dim lamp, giving it a romantic look. Emma could tell by the red clothes lying around that this was Rose's room. She approached the bed. David was between the other girls, and they were all half lying, half sitting leaned back against some pillows. Emma climbed on the bed and sat at the foot of it. She handed the joint and lighter to Holly, then handed beers to David and Rose.

"Thank you, house elf!" said Rose with a big, friendly smile.

"You're welcome," said Emma, sitting back at the foot of the bed. She took in the sight of these three perfect humans in front of her. They were the sexiest people she'd ever seen.

"You know," said Rose, "I wouldn't mind getting cleaned up the way you cleaned up Holly. I'm sure David wouldn't mind, either."

"Oh, yeah, of course." Emma crawled forward and licked one of Rose's big breasts, trying not to look too eager. She didn't want to admit that she'd been thinking about this since Rose had sent her that wonderful picture of David sucking Holly's tit this morning. She licked up all of David's cum off Rose's large breasts, then covered them a couple more times, just to make sure. Then she gave up on being subtle and popped an erect nipple into her mouth, sucking hard.

"Mmmm, that feels really good," said Rose. "But don't forget the big boy."

Emma let the pert nipple fall out of her mouth. She slid over to David's crotch and started licking his cock clean. Even soft, he was still bigger than most of the guys she'd been with. How had Holly and Rose taken this inside them?! She really wanted it inside her, but it was intimidating. She licked up and down it as David and the twins softly chatted about school, politics, and where they were from. Eventually they put down the drinks and started exploring each other's bodies again. Emma lost track of time and kept licking long after he was clean, although he showed no indication that he wanted her to stop. After awhile, he started to get hard again.

"You know, I think I'm ready for another round," said David. "Whose turn is it?"
