Everyone goes through puberty. Black or white, boy or girl, you're going to deal with it sooner or later. For Lincoln Loud, sooner or later wound up being his eleventh summer. One day, he was a sweet and shy little boy who loved his sisters and would do anything for his family, the next, he was a gangly gorilla with hair on his upper lip and a mean scowl perpetually tattooed on his face. He turned mean, rude, and impatient. He ate more red meat and sought out Lynn to play football with him, usually tackling her into the ground just for the hell of it. Worst of all was his, ahem, sexual behavior. When he knocked Lynn down, he would "accidentally" cop a feel of her breast through her shirt; he would constantly go into the basement, dig through the laundry basket, and sniff Lola's panties; and the masturbation...God, the mastubation. It was chronic. He did it in the shower, leaving his, uh, essence in the drain; he did it in his room with the door open; he even did it at dinner once while fixedly across the table at Leni's breasts. Rita only caught him when his fist started to rhymically smack the understand of the table.
Being Lynn and Rita's son, he inherited their prodigious sex drives. Lori had too. Just like Lincoln, she would touch herself at least ten times a day; one time Lori walked in on her furiously humping a pillow, naked from the waist down. Rita saw the writing on the wall and put Lori on birth control. Sex was going to happen, it might as well be safe.
She had the same concern for Lincoln and then some. This was getting out of hand. So she did the most logical thing she could think of: Calling a meeting of her daughters and enlisting their help. Of course, all of them were completely on board with it. Why wouldn't they be? Rita figured it would be best if they all spent time with Lincoln, going from second youngest (Lily being exempted...for now) to oldest. "Are you ready for this, Lisa?" she asked.
"Quite," Lisa said. "I have knowledge on many topics but I am ignorant when it comes to sexual congress and dearly wish to remedy that. I do not like, as you know, being in the dark, as it were."
On their own initiative, Leni and Lola designed sexy lingerie for each of the sisters. Lisa's was green and sheer with stockings and stitching across the chest.
Saturday morning, Lincoln came down stairs in just his underwear and was greeted by Leni and Lori, the former in aquamarine negligee and the latter in blue panties and a see teddy. He jumped back, shoulders squared, and looked around like caveman Spongebob, his dick instantly getting hard. "Hi, Lincy~" Leni said. She turned around and bent at the waist, her legs long and silken and her butt tight, pert, just begging to fucked.
"Morning, Lincoln," Lori said and half-lidded her eyes.
Just then, Lisa came up and slipped her arms around Lincoln's waist from behind. She grabbed his bulge with both hands and squeezed. "You're developing quite nicely, male sibling," she said. "May I perform something of an exam on you?"
Without waiting for a response, she took Lincoln's hand and led him up to her room. Inside, she shut the door and locked it. She stepped into her brother's arms and trailed her finger down his bare chest. She had watched a number of pornographic feature presentations in order to prepare for this. She started to speak, but stopped and took a moment to think of a less clinical way to articulate herself. "I know you're extremely horny," she said, "and I'm here to help. Use my body any way you see fit." She pushed up on her tippy toes and grazed her lips over his. "To put it simply, male sibling, I'm your whore. Do whatever you want to me."
Lincoln heavily knitted his brow in semian distrust...then he flung Lisa onto the bed, and before she knew it, he was pulling her panties down her legs and flinging them over his shoulder, The cool air felt strange and oddly exhilarating on her naked flesh. Lincoln threw himself on top of her and attacked the side of her throat with savage kisses, his hot breath making her skin tighten. He slipped his hand up the front of her dress and rubbed her nipple, sending ripples of sensation through her body. His bulge brushed against her exposed pussy lips and her breath caught with a hiss. Lincoln reached down and tugged his briefs down, allowing his dick to pop out. His hips started to mindlessly thrust and by pure chance, he found her opening and plunged deep inside of her. Pressure swelled in her skull and her tiny body felt like it was going to split in half. Lincoln jerked his hips and slammed into her cervix, bringing tears to her eyes. He pounded her hard and fast, the glans of his penis raking her walls. The pain subsided shortly and pure, utter bliss took its place.
Pulling out, Lincoln rolled her onto her stomach and she got to her knees, dutifully presenting her butt for his purposes. Grabbing her hips, he sank himself into her, making her jump. She grabbed handfuls of the sheet and threw her head back, a squiggly look of rapture settling over her features. She pushed back into his thrusts and her tongue lolled from her mouth. She looked like an idiot but she didn't care. Her entire body was on fire, her heart was pounding, and every time Lincoln's penis prodded her limit, she felt like she was going to blow apart in the most beautiful way possible. Lincoln was enjoying it too because he went faster and harder.
Without warning, he flipped her over, grabbed her ankles, and forced her feet behind her ears. Squatting over her, he buried himself in her in a textbook mating press. Lisa's face turned bright red and her eyes crossed. It felt so good that all she could do was lay there and take it, her body quivering and her mind scrambling. Lincoln rocked his hips, panting and sweating, and didn't stop until he was spurting into her womb. The feeling of his thick, burning hot load put Lisa over the top and she came so hard she almost passed out.
Afterward, Lincoln lay next to her, his hands laced across his chest, and stared up at the ceiling. Lisa lay on her back, panting for air and enjoying the sensation of her brother's load slowly oozing out of her. Finally, she turned to look at him. "How do you feel?"
For a moment, he was silent. "Like a human being again."
"That'll go away," Lisa said, and Lincoln sighed dejectedly. "And when it does, Lola will be there to help you the way I did."
A smile traced Lincoln's lips.
He was really looking forward to fucking her.
"Thanks, Lise," he said. "I mean it."
Lisa patted his chest. "No, thank you. Now I know what sex is like and I very much enjoy it." She leered at her brother. "Would you like fillatio? I've never tasted semen before..."
