The guys were all gathered in Leonard and Sheldon's apartment playing Warlords of Ka'a when there was a knock on the door and Penny and Zack walked in.
Penny was holding a rolled up magazine in her hand. "Hey, your copy of Science magazine was in my mailbox." She passed it to Zack, who was now sitting on the couch next to Leonard, expecting Zack to pass it along.
Zack scanned the magazine. "Check it out, all about planets this month."
Leonard corrected him. "That's an atom."
Zack knew he was right "Agree to disagree. That's what I love about science, there's no one right answer." Zack was well known as the village idiot.
Penny tried to avert the oncoming a train wreck. "Okay, we should, we should go," waving at Zack.
Zack shook his head. "Ah, not yet. I wanna talk science with the science dudes." Penny buried her face in her hands. Zack continued undaunted. "You know, I saw this great thing on the Discovery Channel. Turns out that if you kill a starfish, it'll just come back to life."
Sheldon stared at Zack. "Was the starfish wearing boxer shorts? Because you might have been watching Nickelodeon."
Zack shook his head. "No, I'm almost sure it was the Discovery Channel. It was a great show. They also said dolphins might be smarter than people."
Leonard nodded towards a clueless Zack. "They might be smarter than some people." The science dudes giggled.
Zack, completely oblivious to the fact that they were making fun of him, said, "Well, maybe we can do an experiment to find out."
Sheldon chimed in. "Oh, that's easy enough. We'd need a large tank of water, a hoop to jump through, and a bucket of whatever bite-sized treats you find tasty."
Zack was completely confused. "I don't get it."
Leonard could barely contain himself. "A dolphin might." The science guys busted out laughing.
Zack finally got it. "Oh, I see. You guys are inferring that I'm stupid." He stood up and headed towards the door. "Let's go."
Penny looked at them with disgust. "You know, for a group of guys who claim they spent most of their lives being bullied, you can be real jerks. Shame on all of you," and she walked out the door.
The guys looked at each other. Leonard spoke up. "You think Penny's right? Were we bullying Zack? I don't know, I think we might owe the guy an apology."
Howard shrugged his shoulders. "So go apologize."
"What would I even say?" Leonard asked.
Sheldon offered his suggestion. "Zack, I'm sorry you're stupid. Have a Milk Dud."
Across the hall in Penny's apartment, Zack was sulking like a little child. "They were making fun of me."
"I know, Sweetie," she said sympathetically. "I know what'll make you feel better though." She lifted her top over her head, revealing a lacy blue bra trying to restrain her 34Cs.
Zack's eyes lit up. "Oooo!" She quickly had her bra unclasped and thrown across the room. She pinched her erect nipples. "Yay! Boobies!" Before he had a chance to maul her magnificent tits she was on her knees undoing his pants.
Zack might be dumber than a bag of hammers but there was one thing Penny couldn't get enough of from him. He was hung like a horse! And he was always ready for action. She yanked his pants and boxers down, releasing his beast. 10 inches long with a girth so thick she could barely get her mouth around it. But she always found a way.
"Oh. OH! You're right, I do feel better!" Zack exclaimed as she took him into her mouth.
Her head bobbed furiously, his tool slamming against the back of her mouth. Try as she might, she had yet to be able to deep throat him. His meat was just too much. What she couldn't shove down her throat her hands wrapped around and stroked hard and fast. Zack grabbed her by the back of her head and thrust his hips as hard and as fast as he could.
Just as she felt his rod begin to pulse in her mouth there was a knock on the door.
Knock-knock-knock. "Penny." Knock-knock-knock. "Penny." Knock-knock-knock. "Penny."
Penny took Zack out of her mouth. She yelled over her shoulder, "Go away Sh-OH!" She didn't get to finish the sentence. Zack shot stream after stream of thick spunk all over the side of her face and across her tits. Before she could take him back into her mouth she was covered in white jizz from her hairline on her right side down to her entire chest.
"We came to talk to Zack," Leonard said through the door.
Zack had already tucked his beast back into its cage. He strolled to the door, not giving it a second thought that Penny was on her knees covered in cum.
"Zack!" she yelled. He opened the door. Penny grabbed her shirt and dove behind the couch. "ZACK!"
Zack opened the door to find Leonard, Sheldon, Howard, and Raj standing before him.
"Are we interrupting anything?" Leonard asked.
"No. Penny was just showing me her boobies and sucking my dick," Zack said matter-of-factly.
"ZACK!" could be heard from inside the apartment from a mortified Penny. Leonard, Raj, and Howard got instant chubbies. Sheldon thought the notion was disgustingly unsanitary.
"What do you want?" Zack asked, still clearly upset with how they treated him.
"Listen, uh, the stuff we were saying before, we were just kidding around," Leonard said apologetically.
"No, you weren't. You were making fun of me."
Sheldon held out his box of candy. "Milk Dud?"
Zack smiled like a little child and accepted Sheldon's offering. "Oh, I love Milk Duds. Okay, we're cool. You guys want to come in and have a beer?"
Leonard shrugged his shoulders. "Uh, we're on our way to the comic book store."
Zack's spirit raised. "Really? I haven't been to a comic book store in literally a million years."
