"Speak for yourself," Becky said, and dove down on his cock. She took it nearly to the base, and stayed there for a moment. Becky and Kelly went back to sucking his cock, while Lindsey bent over him, and Cassie ate out Liz next to them. The room quickly filled with the sounds of sucking and moaning. After a few minutes they all switched. Cassie took Kelly's place beside Becky, and Lindsey moved over to Liz. Kelly leaned over Justin's head, and he started playing with her tits. They kept going like that for a while, occasionally swapping spots.
Justin was loving the tag team blowjob he was getting. He reached out blindly with his hands, and found bodies on either side of him. His left hand was on a stomach, and it slowly crept along the tight body until it found a nice soft pair of big tits. His right hand found a leg, and inched its way up to a nice wet pussy, and started fingering it. Kelly swung a leg over his head, and lowered her pussy onto his face so he couldn't see anything.
Justin let his hands do their work to the unknown bodies, while he got a double blowjob, and ate Kelly out from underneath her. He could feel himself starting to get close, and already it felt like it was going to be massive. Once Kelly came, she climbed off of his head, and he looked around. He saw that one of his hands was fingering Cassie, who looked like she was thoroughly enjoying it. He turned his head, and his eyes went wide as he saw his other hand squeezing his sister's tit. Lindsey was between her legs, eating her out, and Liz had her head thrown back, but she must know it was Justin massaging her tits. It was the best feeling tit he had ever felt, big and soft and perfect. He felt his orgasm coming on fast.
"Oh shit," he said, taking his hand out of Cassie's pussy, but not off Liz's tit. "Oh man, here it comes," he groaned. Becky came off his cock, and started jerking him off with both hands. The rest of the girls all got down by his legs to watch the show. Liz stayed where she was, with Justin still kneading her tit. Justin let out a deep groan, and then it started.
The first shot was thick and white, and flew high into the air. The girls all let out noises of shock as the rope flew up, and then fell down onto Becky's face. A second, equally big rope shot up, just as high, and then landed on Cassie. Big thick ropes shot out one after the other. They all watched in awe as cum rained down around them. Justin knew he was supposed to be counting, but it felt too good. Lucky for him the girls were all counting. When the eighth big rope of cum shot up none of them could believe it. And it didn't stop there. Justin shot a total of eleven big thick ropes of cum before it finally subsided. In the middle he felt Liz's tit shaking in his hand, and he glanced over briefly, and could tell she was cumming too as she watched it.
"Holy fucking shit," Kelly said once it was done. "That was without a doubt the biggest load ever."
"I counted ten shots," Lindsey said, her eyes wide.
"Eleven," Becky corrected her. "And they were all thick too."
"But not too thick," Cassie said, already scooping cum into her mouth. "They were just right."
"I feel like I have five guy's loads on me," Kelly laughed, looking at all the cum that had gotten on her, "and most of it didn't even get on me."
"What did that feel like," Becky asked Justin.
"Amazing," he sighed, finally letting go of his sister's tit. "I've never felt anything like that."
"We should see how big your second load is," Becky suggested, and instantly went back to sucking Justin's cock. Lindsey joined her, as did Cassie. Kelly went over to Liz, and they started making out. Justin watched, and then saw Liz's hands on Kelly's tits, rubbing his cum into them. When they broke the kiss, Liz bent down, and took Kelly's tit in her mouth. Justin watched as Liz licked his cum off of Kelly's tits. He stared longingly as his sister licked and sucked his cum off of Kelly's nice big tits.
He felt the mouths leave his cock, and looked down to see the girls moving about. Becky was climbing on top of Cassie, while Lindsey was getting on top of Justin. He took her hips in his hands as she lowered herself down onto him. Her pussy felt especially tight as his cock slid into it.
"Oh fuck, you really do feel bigger," Lindsey said, a strained look on her face. "I don't think you need to take anymore big dick pills."
"You already had the biggest cock any of us had ever seen," Kelly pointed out, with Liz still playing with and sucking on her tits. "Why did you make it bigger again?"
"I don't know," Justin lied. The truth was that he had also noticed his sister exclusively trying out the big dick pills. It was clear enough to Justin, even if it wasn't to her, that she had a thing for big dicks. Even if she hadn't before, she did now. He had seen the way she looked at his dick, and that was hotter than anything else. He would never admit that he was wildly attracted to his big sister, but deep down he knew it. And he wanted her to like him too. More than anything he wanted to impress her with his sexual prowess, the way he had always been impressed by her. And with Liz clearly being on the hunt for big dicks, Justin didn't want anyone to beat him. He intended to be the biggest dick his sister saw, no matter what.
The news that a big black star athlete had come close to his size was rather distressing. But that had been before they saw that he had grown again. Lindsey might be struggling with it, but Justin could see the look in Liz's eyes as she stared at it. It was exactly what he wanted. He didn't even care how big he got, just as long as he was the biggest hottest dick his sister saw. And if he made sure to keep it that way, then maybe she might do more than just watch.
"Well if you get any bigger, its going to be pretty hard to fuck you," Lindsey said, as she slowly rode his cock. Her face was all scrunched up, and she was clearly struggling with his size. "It already feels too big for me."
"Let me try," Kelly said. "I'll tell you if its too big or not."
"No, its still my turn," Lindsey said, still grinding slowly on Justin's cock.
"Well then it must not be too big," Kelly laughed.
"Its not too big yet," Lindsey said, beginning to pant slightly. "But it will be if it gets any bigger. I'd already prefer if it was a little smaller. I liked it better before. Now it feels like its stretching me open."
"Sorry," Justin said, with his hands on Lindsey's hips as she gently rode him. She did feel incredibly tight, but he wished she would pick up the pace a little. He had already cum, and she was moving so slow that it felt like he was just stuck inside her.
"Don't be sorry yet," Cassie said. "Lindsey is the smallest girl here. She might be the only one who thinks its too big. We'll all have to get our turn before we make any judgements."
"Ok," Justin nodded, "anyone else want a turn?"
"Hey, I'm not done yet," Lindsey said, still lifting her butt slowly up and down.
"I think you're going a little too slow for Justin," Cassie said. "Its not your fault," she added. "But maybe he is too big for you now. Why don't you let me take a go, and Becky can finish you off."
"Fine," Lindsey sighed, and climbed off of Justin with a sad defeated look. She lay down, and Becky quickly climbed on top of her, and began playing with her big tits. Cassie took Lindsey's spot on top of Justin. He took her hips in his hands, and then she was lowering herself down onto him. She felt very tight, but not as tight as Lindsey.
"Fuck, you do feel bigger," Cassie said, and for a moment Justin started to get worried. He hadn't made any way of reversing the long-term pills, and if he over shot it then he might have fucked the whole thing up. "But not too big," Cassie added, and Justin let out a sigh of relief. "You probably shouldn't take anymore though," Cassie said. "Or if you do, make it the one-time pill. Lindsey's right that if you get any bigger than this it might be too much."
"Or maybe you two are just being pussies," Kelly said. "I think his cock looks perfect. And Liz is the real big cock expert here. What do you think Liz? Does Justin's cock look too big?" Justin and Liz both looked at each other, their eyes met, and they both turned away blushing.
"It definitely looks really big," Liz said, staring at Justin's cock as Cassie rode it. "But its hard to judge without trying it out myself."
"Are you saying you're finally ready to take a go at Justin's cock?" Kelly asked excitedly.
"No," Liz said quickly. "I cant do that. I'm just saying that its hard to judge if its too big or not by just looking."
"Then maybe you should do more than just look," Kelly goaded her. "We all know you want to, and we all know Justin wants you to. Why don't you two just stop pretending and get it on already."
"Because he's my brother," Liz said. "We can't do that."
"Babe, you're sucking his cum off my tits as we speak," Kelly pointed out. "And he just came a river while he grabbed your tit. You've already crossed the line, why not just do what we all know you both want to?" No one said anything for a moment. Liz was thinking about it. Part of her knew that Kelly was right. She did want to try Justin's huge cock. And they had already crossed the line. But she just wasn't ready to take that last step yet.
Justin didn't need to think about it at all. He wanted nothing more than to have his sister do anything or everything to his cock. He would be happy with her just touching it. He wouldn't say it out loud, because he knew she wasn't there yet, but he wanted it. And he thought that Kelly was right, Liz wanted it too, she just needed more time. Justin knew that if he waited, the payoff would be worth it. And in the meantime, he got to fuck the others.
"I'm not going to fuck my brother," Liz said, trying to sound offended and coming up just short.
"What about sucking it," Becky suggested. "We all want to see how deep you can take it."
"I'm not going to suck my brother's cock either," Liz said angrily. "Now if you don't drop it I'm leaving."
"Ok, leave her be, we still need her to take the notes," Justin said. In reality he just didn't want her to leave. He would rather her be there to watch and occasionally join in a little bit then not be there at all. She wasn't even taking notes anymore; she was fully participating, just not with Justin directly. But he wanted her in the bed.
"It really is big Justin," Cassie moaned softly as she rode his cock. He could feel her tight wet pussy hugging his cock tightly. He felt her pace quicken a bit, as well as her breathing, and then she was vibrating slightly, having a nice orgasm as she rode him. She fell down off of him as her orgasm subsided.
