Leni was more than an airhead. She'd demonstrated the fact more than once.

If there was one thing she could pick up on, it was her sisters in distress. Lynn was practicing batting and pitching so quickly, she was practically playing a game of baseball herself. Lucy was dealing with serious writer's block, going so far as to rip pages out of her beloved journal in frustration. Luna was shredding away at her guitar, cursing up a storm when she inevitably broke a string. Luan was doing a one-man stand-up show for Mr. Coconuts – and booing herself offstage.

Leni might not have been the sharpest tool in the shed, but even she could see the situation was leaving her siblings in pain. Smiling all the while, she called her fellow harem collaborators to the guest room where she was staying.

"I think we should move up our plans." She announced once the door was shut.

"What plans?" Lynn asked, fidgeting without a baseball in her hand, "You mean yours and Lincoln's date?"

"I mean the, um…" Leni scrunched her brow, "What's the word, again? It starts with a zero…"

"Zero isn't a letter, Leni." Lucy sighed.

"Sound it out." Luan offered.

"Org-ee?" Leni said, painfully slow. It didn't take a genius to figure out what word she'd been reaching for, and every other face turned crimson.

"B-but what about your date?" Luna asked, "It's not fair that we skip yours."

"It's not fair to make all of you wait." Leni pointed out, "Besides, this is just like a date! Only with all of you instead of just Lincoln."

"We have lost four days, already." Lynn mentioned, "This is our last day with the house to ourselves in, well, a long time."

"We've already said if Lincoln can't do it with all of us, he's not going to do it with any of us." Lucy noted, "We have to strike today, before mom and dad get home."

"Lisa will have to keep Lana and Lola busy." Luna said, excitement creeping into her voice.

"Oh man, are we really doing this?" Lynn grinned, "Somebody pinch me! OW!"

"What?" Leni shrugged, "You asked me to."

"Alright girls," Luan said, "Let's get ready to rock Lincoln's world."

Anxious, the five girls split up into two teams. One was supposed to convince Lisa to distract the twins for them; the other was to seize Lincoln and bring him to the guest room. Lisa didn't need much convincing – her only request was that Luan record the whole thing for studying later, which only added to the excitement. The hard part was Lincoln.

"What's going on?!" he demanded.

He was being dragged from his bed by what could only be his sisters. As usual, he was wearing nothing but his underwear – the better to enjoy reading his comic books in. This was a new and frightful experience for him, being dragged through the house in only his skivvies. Then again, he probably should have come to expect this, given the antics his family usually engaged in.

He grunted as he was thrown onto something soft. Looking around, he saw he was in the guest room. Both beds had been pushed together to form a single platform, and he was dead center. What surrounded him, though, left him speechless. He thought his nose might be bleeding.

Leni was wearing lingerie, probably something her douche of an ex-boyfriend bought her by the look of how… revealing it was. Luna wore fishnet tights with her usual plaid skirt, a leather jacket and a bra being her only other clothing, with her face done up in Glam Rock paint. Luan wore her usual attire, oddly, and was holding… a camera? Lynn wore her sports jersey – and Lincoln was convinced that was all she was wearing. Finally, there was Lucy, wearing a greatly reduced Lolita cosplay.

"What are you guys doing?!" Lincoln asked, aghast.

"Getting you laid." Luan explained, turning the camera on, "I believe Lucy had first dibs."

"I'm not doing that to Lucy!" Lincoln protested. As he started to get up, Lynn and Luna held his arms down while Leni held his legs. "Are you guys crazy? Lucy's only ten!"

"We're not giving you a choice this time." Lucy informed her brother, stealing a kiss as she straddled him, "You promised to see this through; none of us can wait any longer."

"I-I don't want to!" Lincoln struggled against his sisters, but they were already tying his limbs to the bedposts.

"You will." Lucy smiled. She brushed the skirt of her costume back, revealing her lack of underpants. Pale and perfect were the only words that came to Lincoln's mind, and he knew his nose was bleeding this time.

"L-Lucy!" Lincoln huffed, his breathing becoming ragged as his arousal increased, "Think about this!"

"It's all I've thought about for the last two years." She confessed.

Before Lincoln could say anything else, Lucy positioned his penis beneath her and sat down. Both Lincoln and Lucy shivered in pleasure and pain at the experience. Lincoln's breath caught in his throat. He paled at the sight of blood trickling down his member.

"Lucy, are you alright?" he asked, nothing but concern etched on his flustered face.

"Y-yeah." Lucy said, "Give me a second."

Lucy slowly ground her hips against Lincoln. Lincoln resisted the urge to thrust back and forth; clearly Lucy was in pain and needed a moment to work up to it. Part of Lincoln was screaming out about the wrongness of the whole situation. Incest aside, Lincoln was literally inside a ten-year-old – and enjoying it, no less. If this were ever discovered, he could face serious criminal charges.

And Luan was filming it all!

"Ok, here I go." Lucy said, short of breath.

She lifted herself and fell back down. All thoughts of repercussions fled Lincoln's mind as his body flooded with pleasure. How could something so wrong feel so good? Up and down she went, driving Lincoln crazier and crazier. He gripped the belts binding him to the bed, practically making his hands bleed from the tightness. Finally, with one last drop, Lincoln couldn't hold on any longer.

Both of them screamed in ecstasy as Lincoln erupted into her. He hadn't realized he'd been saving so much up until it was all released. His fingers twitched uncontrollably, his toes curled. Lucy felt herself overflowing. It was everything she had dreamed it would be, and more. Her own toes were curling and she placed her hands on Lincoln's firm chest for balance as her head whited out. After a few minutes, she rolled off and next to him.

"Now that's what I call a money shot!" Luan laughed, replaying their orgasm on her camera.

"You, like, did great for your first time, Linc!" Leni said, "You lasted longer than my ex-boyfriend!"

"I've really gone and done it, haven't I?" he asked himself between pants, "I just came in my ten-year-old sister…"

"It was consensual." Lucy said, "Besides, technically we raped you."

"Oh yeah, that's comforting." Lincoln muttered, "Look, can you untie me? I'm not going anywhere now."

His sisters complied and Lincoln massaged his wrists. The bindings had gotten really tight when he climaxed.

"Did you enjoy it?" he asked. Nothing for it, now.

"It was the single greatest moment of my life." Lucy said, "My only regret is I'm too young to have your children."

Oh God, he'd forgotten about that little fact!

"So, who's next?" Luna asked as she helped Lucy onto a towel. Lincoln was both aroused and disturbed at how much cum was spilling out of her.

"Up to Lincoln." Luan shrugged, "I mean, it is his body we're using."

Lincoln never liked to choose between his sisters, but immediately he turned his head towards one in particular. She had tormented him with her body for years… Now was his time for sweet relief.

"Lynn." He challenged, "If she thinks she's up for it."

"Oh, heck yeah!" Lynn tackled her brother onto the bed. She rubbed her pussy against his member, getting it erect again within moments, but didn't insert it.

"Um… if you don't want to, I won't make fun of you." Lincoln said, "B-but please do something. I'm going crazy here!"

"I don't like to repeat acts, so I'm trying to think of something original." Lynn explained, "Got it!"

With all the finesse of a master gymnast, Lynn flipped herself around and thrust her rear into Lincoln's face. The scent of her womanhood made Lincoln's head dizzy. He could barely hear the catcalls from his fellow sister-lovers. Lynn kept stroking his dick.

"Well, bro?" she said, "Dig in!"

Before Lincoln could question what he was supposed to do, he felt Lynn's soft and supple lips wrap around his penis. Unsure of what to do, he let instinct drive him. He used his fingers to spread her lips apart and set about nibbling at the soft, pink flesh that he exposed, kissing and licking where he felt he had been too rough. He was rewarded with Lynn bobbing her head faster and faster, taking more and more of his member into her mouth as she went.

It became too much for Luna to bear and she reached under her skirt. Masturbating was so much easier without panties, and she set about massaging her clit. The ecstasy caused her to fall to her knees. She saw Luan film her for a moment, the comedian's face a flushed grin. Leni came over and knelt beside Luna.

"Let me help." Leni said, placing her hand over Luna's. Before the rocker could get over her surprise, their lips met and the rocker melted into a passionate kiss.

Lynn moaned into her blowjob as she came. Lincoln was remarkably skilled for a virgin! She briefly wondered how much porn he must watch, but her mouth filled up with Lincoln's seed. Surprised, but not unpleased with the evidence of her success, Lynn forced herself to swallow. She collapsed in a panting mess, rolling off of her brother.

"Holy mackerel, Linc!" the jock said, head blanking for a moment, "You're still hard?"

"Isn't that normal?" Lincoln asked.

"It's downright miraculous!" Luan giggled.

She looked almost pained, scraping her knees together in frustration. Lincoln noticed Leni and Luna were preoccupied in a make-out session, jilling each other off. He felt his dick harden, almost painfully, at the sight. Lynn was already enjoying her afterglow with Lucy, the two pecking each other with kisses.

"I guess you're next, Luan." Lincoln shrugged.

"Finally!" the comedian hopped onto the bed, tossing the camera to a stunned Lynn and Lucy. She set about removing her clothes.

Lincoln wondered what Luan had planned.

"I know Lynn would be a tough act to follow, but I couldn't hold out for the finale!" Luan giggled as she inserted Lincoln's penis into her pussy, "Mind if I insert a joke here?"

"Ha… ha." Lincoln panted.

"Stiff audience." Luan continued as she rode her brother's cock. Lincoln struggled to laugh as his breath hitched. Luan was so… tight.

They continued the process of Luan telling jokes while riding her brother. Some were zingers and Lincoln erupted into rather painful fits of laughter. Some were… not so good. The pleasure escalated and Lincoln couldn't help but laugh more and more, sitting up to laugh better. Luan giggled the whole time. Finally, though, Lincoln reached his limit.

"Getting close, aren't you Linc?" Luan asked, almost at her own limit, "I've got one last joke for you."

"Y-yeah?" he asked.

"Wanna know what my favorite slapstick routine is?" she asked.

"W-what?" Lincoln struggled to hold it in.

"The creampie!" Luan said as she slammed herself down.

Lincoln couldn't hold it in and came while laughing. He wasn't the only one – Luan was beside herself in pleasure and giggles. The two of them nearly rolled off the bed from laughing so hard. Lincoln pulled out, and found himself suddenly tired. Perhaps he couldn't keep this up like he thought he could.

"Hey, girls…" he exhaled, "I think I'm about at my limit."

"Are you sure you don't have enough energy left for just one more go?" Leni asked, stretching Luna's pussy open for Lincoln to see.

Lincoln didn't need to reply – his erect dick was answer enough.

"But Leni, that'll leave you out." Lincoln noted.

"Not if Luna, like, does me while you do her." Leni pointed out, "What do you say, Luna? Feel like paying me back?"

"It'll mess up my face paint, but that's never worried me before." The rocker grinned.

Luna laid down on her back. Leni kneeled over her face, facing Lincoln as he prepared to insert his dick into Luna. He was rewarded by a moaning from under Leni, who was biting her own lip in pleasure. Lincoln began pumping more and more vigorously – only now did he realize he hadn't had to thrust before.

"Lincoln," Leni leaned forward, "kiss me."

Lincoln, being the good brother he was, obliged. While his mouth and hips were occupied, he set his hands to attacking Leni's large breasts, massaging them gently. Their tongues danced in a gliding fashion – and Luna's tongue drilled into her older sister. He continued to thrust into Luna, scarcely noticing Lucy, Lynn and Luan making out on the bed. The camera was somewhere on the pillow, long forgotten by the hormonal young adults.

"I'm getting close." Lincoln warned.

"Get off me, Leni." Luna instructed.

Her face paint was a mess and she knelt beside Leni, their faces close together.

"Wank it, bro." Luna said, "Give us a nice finish."

Lincoln couldn't resist such a tempting offer and set about jerking his dick harder and harder. Finally, with all that was left in him, he came. It was still substantial, though smaller than his previous three orgasms. It was still enough to spray across both of his older sisters' faces. He watched as they kissed and licked the cum off of one another, but any attempt at another erection was hindered by pain.

"I can't go anymore." He said, finally.

"It's alright, bro." Luna said, "You did amazing!"

"I'm just glad Lisa made us those super-effective birth control pills!" Luan said.

"Uh… did we take those?" Lynn furrowed her brow.

"I have them right here!" Leni giggled, producing an unopened box.

"Oh…" the other sisters frowned.

Lincoln wanted to cry, but the sound of the front door opening seized his heart in terror.

"Holy mother of-!" he heard his father yell, "Why does the house smell like sex?!"

Lincoln sighed in resignation. It would not be a fun day at the Loud house, after all
