"Another tardy notice?" Mrs. Loud looked at the note she was given, "One more and you'll get detention, Lincoln! What happened?"

"Sorry mom, it's my fault, I was walking past the school auditorium and ...kinda lost track of time watching the cheerleaders practice." Lincoln sheepishly admitted, feeling it was better to tell the truth than try and hide it.

"I appreciate your honesty but this won't do. I thought Lori was helping you out with these...urges?" Mrs. Loud asked.

"She is! I mean, she did last night. It's not Lori's fault, but I get these urges multiple times a day." Lincoln said, blushing. Never in a million years would he think he'd be having this conversation with his own mother.

"It's alright Lincoln, I understand. Leave it to me." Mrs. Loud said as she busily continued to get dinner ready for her family.

"I suppose I forgot how easily excited teenage boys can get." she thought to herself, "And how frequently they get ...worked up..."

She had an idea of what to do, but was hesitant, "Is it really okay to do that, during school?" she wondered to herself, "It doesn't matter, we don't have a choice. If I want to keep him focused on schoolwork I'll need to get more help."

The bell rang and another day of school began for Lincoln. Although he was in school his thoughts were back in his room as he replayed last night's events. He was still getting used to the nightly routine of Lori just walking into his room and within minutes getting him moaning in pure bliss.

In fact he must have been thinking about it too much since he caught himself fantasizing again during class. It was a struggle to focus and it didn't help that he was surrounded by so many girls, both here at school and at home.

On his way to the next class the janitors closet suddenly swung open and he was pulled inside the dark, small room.

"What the- who's here?" Lincoln asked, shocked by this turn of events.

"Well, well, well, if it isn't my lil bro, checking out girls again? tsk tsk." the husky voice said confidently as Lincoln felt himself get pushed against the wall.

"L-Lynn? what are you doing?"

"Sorry to cut to the chase but we don't have all day here." Lynn explained as she locked the door. Before he was even able to question his sister, she started pulling down his pants.

"Trust me bro, this wasn't my idea, but I didn't feel like getting grounded over this." the tomboy said as she slipped her fingers in the elastic of his underwear and pulled them down in one quick motion, letting his already semi-hard member to spring out.

"Damn, Lincoln you're packing! How'd you manage to hide this from us?" Lynn joked as she took a hold of it in her hands and felt his length before sliding a condom over his length. Lincoln could only let out a sigh as even more blood rushed to his shaft making his knees weak.

"This is a lot bigger than the last time I saw you naked, what happened?" she joked, "And I almost forgot about these" she said as she moved her hand down his base until she held his balls in her hand. Lincoln couldn't help tensing as she suddenly began to grope his delicate parts.

"Wow, so sensitive! I guess this is why all the guys on the team have to wear cups." she said as she began massaging them in her hand, "I don't even know how you boys walk around with these things hanging between your legs." she continued, getting more and more enamored by the shear weight of his junk in her hand.

She soon returned to tugging his shaft, causing Lincoln to elicit another moan.

"So what's got you all worked up and bothered today? The cheerleaders? Or are you just excited your own sister was gunna be jackin' you off in school today?" Lynn teased as she upped the tempo even further. For Lincoln, even though he was terrified of having his sister doing this in the middle of the school day, he couldn't deny how badly he needed this or how amazing it felt.

"So is this gunna take much longer? Or am I gunna get a note for tardiness too?" She was now stroking him all the way from the tip to the base. It was clear she was treating this like another one of her competitions, but this didn't bother Lincoln in the slightest.

"I could get used to this." he thought to himself as he felt his climax already approaching.

"Maybe this will help speed things up." Lynn said as she took his hand and placed it on her behind, encouraging him to grab a handful of her sporty buns. He instinctively began caressing and massaging her toned butt.

It worked and soon enough she could hear him moan louder until he began shooting so much and with such force it would have gone halfway across the room if it weren't for the condom.

"Wew, look at that time, must be a new record right?" she said proudly, clearly pleased with her achievement.

"Well it was fun, but I have to get ready for the big game tonight." Lynn said as she tucked his semi-hard member back in his underwear and patted his bulge.

"Same time tomorrow?" she whispered in his ear before slipping out of the closet leaving Lincoln still in a daze.

***

Lincoln got back home late that day. Having to spend extra time in detention meant he'd missed Lynn's big match that the rest of the house was attending.

As he walked through the front door, he was surprised to find Lori laying on the sofa, already dressed in her classic nightwear of white tank top and shorts.

"Oh hey Lori, why didn't you go with the others?"

"I was literally falling asleep. Until you woke me, twerp." She explained, clearly annoyed.

It was true Lori was tired but she didn't want to admit that the reason she couldn't sleep was from the pent up energy she had accumulated from all the lewd activities she had to do for Lincoln. Jacking a guy off, even if it's you're little brother, was a sexually frustrating experience, especially when Lori wasn't getting satisfied. She had planned to visit Bobby tomorrow night but it felt like a long time to wait.

"Sorry Lori, is there anything I can do for you?" Lincoln asked as he sat next to her on the sofa, clearly feeling bad about interrupting her nap.

"Foot massage. Now." she bluntly stated as she placed her legs on his lap.

Lincoln was a bit nervous; he had never done this before and he didn't know how to give a proper massage. He started by gently rubbing her feet until Lori suddenly started giggling.

"L-Lincoln no, not li-hahaha. Not like that, it's too ticklish! You have to rub harder." she explained as she regained her composure.

Lincoln followed her instructions and applied more pressure and ran his hands further along her feet, from her toes up to her ankles. As he got more and more used to it, he continued to move further and further up her legs. Taking care not to miss any area of her calfs before moving further up to her knees until reaching her thighs. The more he massage her soft, supple legs, the more aroused he was getting and didn't want it to end just there.

"Oh wow, you're getting good at this." Lori said as she started to get up. But to Lincoln's surprise she lazily rolled over onto her stomach.

"I didn't tell you to stop..."

Lincoln got the hint and repositioned himself to reach her shoulders. He began to senusally massage her neck and worked his way down. Careful to apply the perfect amount of pressure as he massaged over her thin tank top. As he moved to her lower back he realised he was getting more and more excited and could feel himself getting hard. He hadn't realised it until now, but since he was straddling her waist he was fully pressing up against her plump, soft butt. Lori either didn't notice or didn't mind and continued to enjoy the deep tissue massage Lincoln was giving her.

"Ahh, why'd you stop? Keep going that litterally feels amazing." Lori encouraged him and so he continued moving down to her lower back, making sure to give special attention to every square inch. But the more he massaged, the more excited he got until Lori couldn't ignore the fact he was lewdly poking her butt.

"Not again! Lincoln! Can't you control that thing!?"

"It's not my fault, I can't help it!"

"Well, don't look at me! I'm not in the mood to jack you off."

"That's not fair Lori, it's only like this from massaging you."

"I don't care, if you're so desperate then figure it out."

Lincoln stared at his sister trying to figure it a way to deal with his dilemma. He was so horny now that simply pressing up against Lori felt amazing. He gently rocked back and forth, pushing his waist against her thin shorts which barely covered her protruding butt.

It felt good. Really good. So much so that he gradually increased the tempo until his shaft was begging to be released from it's confined prison. His horniness melted away any embarrassment or shame he had as he unzipped his pants to allow him to experience a more visceral sensation of rubbing up against Lori.

As Lincoln increased his rocking more and more his member slipped underneath Lori's shorts and was now pressing directly against her panty covered hot mound. Lori's annoyance soon turned to excitement as she felt Lincoln rubbing against her sensitive area with only a thin pair of underwear between them.

Lincoln continued to pick up speed and could swear it felt like it was getting hotter. Lori couldn't pretend to ignore it any longer and let out soft moans each time Lincoln's log slid between her legs and pressed against her damp panties. Lincoln soon got lost in the sensation and found himself bucking almost instinctively as he craved to be between this girls legs.

Meanwhile Lori subconsciously widened her legs to allow easier access to her most sensitive spot. She didn't realize simply humping could feel this good and started getting really into it. The sexual frustration over the last few days had built and now she felt the tension melting. She buried her face in the sofa cushion to muffle her moans as she finally felt her orgasm wash over her entire body.

Lincoln didn't even notice Lori's release as his frenzied humping soon brought him to his own climax and he felt his entire body get enveloped in bliss. As he caught his own breath he realized what he'd done.

"Great, these shorts are ruined."

***

Lincoln was sitting in his room, wearing his classic red underwear and reading various comics. He looked over at his bedside clock and realised it was getting late. He'd hope Lori would visit him soon, otherwise he'd have to go and find her. Just as he was about to get up he heard footsteps outside room, followed by a knock at his door before it opened to reveal a blonde girl; but not the blonde sister he was expecting.

"Hey Lincy, are you ready?" he heard his older sister ask she walked in wearing a skimpy outfit.

"Leni! What are you doing here?" the white haired teen asked as he watched her take a seat next to him on his bed.

"Since Lori is at the movies with Bobby she asked me to help you tonight." she explained in her cheery, friendly manner, "I hope that's okay?"

Lincoln was in disbelief, last week he could only dream of having any girl offer to jack him off, now he was about to have a third girl. Leni moved closer along the bed before poking at his swelling bulge through his underwear.

"You know, I could totes make you a new pair if you wanted." she said as she began to pull on his underwear, "It looks like you've outgrown them."

As soon as his log was freed, Leni wrapped her fingers around his base and inquisitively began examining it with great interest. It wasn't long before she began to slowly move her hand along his length. Lincoln just stared in shock at Leni, not sure if he should tell her she had forgotten to put a condom on. But as soon as she touched his member he couldn't bring himself to tell her.

"Wow Lincy, it's so big!" the blonde said as she clumsily held it in her hand, the sensation of a hot teen blonde holding it made Lincoln groin as his member involuntarily twitched.

"And it's getting bigger!" Leni continued, completely fascinated by this new discovery.

Either by intuition or on purpose, Leni seemed to hone in on what to do and seemingly knew exactly where Lincoln's weakest points were. She stroked his entire length all the way from his base to the tip several times before focusing his bulbous head in her hand. This elicited a moan from Lincoln which encouraged Leni further.

"Do you like this, Lincy?" she looked up at him smiling innocently. Lincoln could only nod as he sucked in a breath of air. But when he glanced down at Leni something else caught his eye; her amble cleavage was on show for anyone to see, as if to tempt him further.

Normally, Lincoln wouldn't dare stare at his sisters cleavage, even when they would be clearly on show, like when leaving the bathroom or during the many backyard pool days in the summer. But this was even more revealing. As her stroking increased temp, Lincoln noticed her string top slipping down her slender shoulder revealing more and more of her perky breast. Leni either didn't notice or didn't care as she became more and more focused on stroking his now fully hardened cock. Lincoln could feel himself getting close as the familiar sensation built deep within him. Leni seemed to notice something was happening as she commented on the bead of precum oozing from his tip.

"Ohhh what's this, Linc?" Leni asked as she brought her head closer to his raging cock. She was so close he could feel her hot breath on his dick and that was enough to send him over the edge.

"Leni, wait, I'm goin t-" was all he could get out but Leni's final stroke pushed him over the edge. A thick rope shot out and hit Leni directly on her cheek causing her to yelp in shock. What surprised Lincoln even more was what Leni decided to do next. In an attempt to prevent a mess on her bed and clothing she decided the best thing was to catch this mess using the only thing available to her; her mouth. Her lips wrapped around his cock which made Lincoln short circuit. His cock spasmed even harder as he realised this hot, warm, pleasant feeling was in fact Leni's mouth - his first experience of a blowjob. His cock continued to erupt inside her mouth until he could swear he could feel her sucking on him.

After what felt like an eternity, Leni finally pulled off his member and he could hear an audible gulp as Leni swallowed his sizeable load.

"Woah, Lori wasn't kidding when she said it was a lot!" Leni enthusiastically said as she finished wiping away any remain evidence from her face, "But you got some on my dress!" Leni said, inspecting her top.

"Oh, sorry Leni, but that was incredible. Especially the part when you used your mouth." Lincoln gasped as he saw her taking off her top, revealing her large yet perky tits for anyone to see.

"I just didn't want to not make a mess." Leni casually explained.

"Uhh, yeah, of course, makes sense." Lincoln happily agreed, unable to take his eyes off his older sister's exposed tits. Leni was blessed by having the largest breasts in the house, even more than Lori which caused a bit of jealousy. Lincoln first noticed how big Leni had gotten on a summer pool day a few summers ago and they had only gotten bigger since. He's never seen one naked in person before and despite only just getting milked dry he couldn't help but still feeling hot and bothered, and it showed as his member began to reinflate.

"Oh no! I must not have done a good job, sorry Lincy." Leni said as she noticed his hardening member right in front of her face.

"It was good Leni, actually too good. Could you give me ...another blowjob?" Lincoln asked coyly, seeing how far he could push his good luck.

"Blowjob? Don't be silly. I told you, Lori said I was only allowed to use my hands to make you feel good. But if it's just for cleanup then I think it should be okay." Clearly confident in her rationale.

Without warning, Leni took the hardened member and wrapped her mouth over just the tip and began to rhythmically stroke on his shaft with her hand. He practically melted as he felt her warm and wet mouth around his most sensitive region. He looked down and saw her big innocent eyes looking up at him as she tried to speak with her mouth full.

"Doesh tdhis fheel ghood?" she mumbled as she kept her head still and increased her stroking, making sure her hands were doing all the work. Just speaking made her tongue dance on the underside of his cock head, stimulating him even further.

Lincoln couldn't stop his hips from rocking forward and began to push more of his shaft past her lips and into her warm, wet mouth. Leni continued to stroke his length with her hand but her mouth felt so inviting that he neeed more. It wasn't long before he was full on face fucking her mouth and she was no longer needing to stroke him at all and letting the teenager do all the work.

Lincoln kept increasing the pace until he couldn't take anymore and could feel his balls twitching again. He had no choice but to hold onto Leni's head for support as he shot an even bigger load straight down her awaiting throat. Leni didn't seem to mind in the slightest as Lincoln collapsed right there and then, completely spent.

Happy with how effectively she was able to help satisfy her younger brother, Leni took the opportunity to take her dirty clothing to the laundry room downstairs. As she passed the kitchen she saw her mother getting ready for her second shift and told her mom about what just happened.

"You let him finished in your mouth, Leni?" Mrs. Loud was somewhat surprised and taken aback upon hearing this from her own daughter.

"Yep, twice! He was totes happy and satisfied afterwards too!" Leni happily replied, confident she had done a good job as asked.

"Well, I suppose it's pretty much the same thing as jerking him off. Just make sure you're not letting any of his stuff get anywhere near you ...down there." she said, pointing to her waist.

"As long as Lincoln's satisfied then he'll be able to focus on his studies." Mrs. Loud continued rationalizing the situation out out loud.

"Yeah exactly, and also look on the bright side, we're totes saving money on condoms!" Leni reminded her.
