Chapter 2: ‘I’ll Show You Mine’

 

During dinner, Allison and Lisa continued their conversation, often putting their heads together and glancing over in Bart’s direction. Each time they did so, they would both giggle a little, which naturally perplexed the boy as he was sure they were talking about him. Although Bart didn’t know it yet, it was going to be a very memorable night for the three of them.

 

After they had all finished eating, Allison offered to help Marge with the dishes giving Lisa a chance to take her brother aside and let him know what they had planned. From the kitchen she could see Bart’s eyes go wide as Lisa whispered in his ear, with him then whispering back to his sister before receiving a nod from her. It was quite clear from the smile crossing his face that he was more than happy for Allison to participate in their little game, which Lisa confirmed as she re-entered the kitchen.

 

“Bart can’t wait,” she whispered. “He’ll come to our room once mom and dad have gone to bed.” To which the younger girl merely smiled and nodded.

 

They spent the rest of the evening in front of the TV, playing games, and generally having a good time. It was the weekend, so they had all been allowed to stay up later then usual. Soon, however, it was time for bed, with Bart catching Lisa winking at Allison letting her know that the fun was about to begin. Saying goodnight to Marge, plus Homer who had only just returned from Moe’s, the kids all got washed up and then went to their respective rooms, all of them waiting impatiently for the grown-ups to do the same and the lights to go out in their bedroom.

 

Eventually, all fell silent in the Simpson home, although Bart himself waited another ten minutes or so just to be safe. Then, he quietly opened his door and tip-toed down the hall to the girls’ room. Arriving at the door, Bart knocked softly, hearing muffled giggles from the other side. Understandably, he was a bit nervous, not because of his sister but because Allison was there too, an unfair advantage to be sure.

 

A few seconds later Lisa gently opened the door for her brother and ushered him inside with a friendly smile. “This is gonna be so much fun,” she whispered, keeping her voice down until the door was closed and all three of them were in the room together.

 

Allison was sitting on Lisa’s bed dressed in a pretty, light green nightie. She visibly blushed when the older boy’s eyes’s fell on her. “Oh, hi Bart!” she said, trying not to look too embarrassed by his presence.

 

Bart wore his usual, bright green pajamas, which were already beginning to feel a little tight around his crotch. Lisa, dressed in her blue nightie, looked at Allison and then at her brother, a mischievous smile crossing her face as she did so.

 

“Hey, Bart! Why don’t we start with you showing Allison your thing? She really wants to see it!” Lisa chirped.

 

“Come on, Lisa! You know I didn’t say that, not exactly,” the younger girl cried, a bit too loudly for comfort perhaps.

 

“Ssshh! You’ll wake our mom up,” Lisa warned, putting a finger to her lips. Bart nodded, knowing full well Homer wouldn’t disturb them if a bomb went off next to him, but that mom was a different story entirely.

 

“Ah, heh! Sorry guys,” Allison said sheepishly.

 

“That’s okay,” Lisa said, “but we’d better try and keep it down from now on.” All of them nodded in agreement.

 

Bart then looked across at Allison with a smile. “So, Allison… Do you really wanna see it?” he asked.

 

The pretty, little brunette pondered for a moment, flushed a bright shade of red, then squeaked, “Yes!”

 

“We can’t hear you,” Bart and Lisa both said together, tickled pink by her sweet innocence.

 

“Oh come on, you know I do!” Allison said, a little louder than before.

 

“Okay, if that’s what you want, but you’ve got to show me yours as well,” Bart grinned.

 

Allison’s face remained red as she thought about his offer. Then, looking down, she said in almost a whisper, “Alright…”

 

“Alright what?” Bart and Lisa asked together, both grinning broadly.

 

“Alright! I’ll show you mine if you show me yours,” Allison said with a giggle, scarcely able to believe what she had just said.

 

“Promise?” Bart asked.

 

“Yes, I promise!” she replied.

 

“Okay, here it is,” he said, unabashedly pulling his pajama bottoms down a bit and taking it in his hand to show to the girl.

 

Allison blushed a little again, but she didn’t look away this time. Then, totally out of the blue she said, “It looked bigger before, didn’t it!?”

 

Now it was Bart’s turn to be a bit embarrassed as the young girl’s rather frank outburst elicited a giggle from Lisa. “Um, actually it will get bigger,” she said, grinning at the bashful expression now on her brother’s face. “It’s just that it hasn’t got hard yet. You’ll see what I mean in a minute.”

 

“Oh, okay Bart. Can you make it big for me?” Allison asked innocently.

 

Unlike with his sister earlier in the day though, Bart was clearly feeling a bit self-conscious. Lisa wasn’t sure why it wasn’t happening like before either, but she wasn’t about to give up now.

 

“Maybe it needs a bit of help this time. Go on, try touching it, Allison,” she suggested, knowing full well this is what the enthusiastic girl wanted to do anyway.

 

However, Bart had other ideas. “Hey, wait a minute! You said you’d show me yours too, remember?” he said, just a little annoyed.

 

“Well, I did say that, so alright,” Allison said, her openess surprising Lisa who hadn’t even got round to suggesting yet that she show him hers as a way to get her brother more in the mood.

 

“I guess I may as well take my nightie off as well,” Lisa said as her eager pal reached down and began pulling hers up over her head, then allowing it to fall to the floor, the older girl hurriedly doing the same so as not to be left behind. Although both of them were still undeveloped, having virtually non-existent breasts and hips, this didn’t stop Bart from watching them intently.

 

Next, Allison put her thumbs under the waistband of her pretty white panties and pulled them down to her knees, the crumpled material slipping the rest of the way down of their own accord. Then, stepping out of them, she turned and faced Bart, displaying her private parts almost proudly to the boy. By this time, Lisa had also done the same, her older brother now finding himself confronted by two of the loveliest flowers he had ever seen. In fact, both girls had such perfect vertical lines, he couldn’t decide which one he liked best.

 

“I think he’s in love,” Lisa said, smiling at Allison. Both of them couldn’t fail to notice the way Bart was oogling them, particularly between their legs, his mouth opening and closing like a fish out of water. However, despite the mouth-watering sight before him, not to mention the pleasant churning in his stomach he often felt with his sister during these intimate moments, he still remained flacid down below.

 

“Hmm, still nothing,” Lisa noted, looking at Bart’s limp penis. “Well, I guess we’ll have to take matters into our own hands… or rather, we’ll have to take you into our own hands,” she smirked, winking at her brother.

 

“No, let me do it!” Allison interjected, hurriedly taking a step towards Bart.

 

Lisa could see her friend was genuinely interested now, so she let her have her way. “Okay, be my guest,” she gestured, smiling broadly.

 

“It’s alright, isn’t it, Bart?” Allison asked, the young girl’s hand just inches away from his boyhood.

 

“Yeah, go ahead,” the older boy replied, still a little nervous himself, though he had no idea why since he never had a problem with his sister before now.

 

Upon hearing this and no doubt sensing Bart’s uneasiness, Allison looked down again, gingerly reaching out and briefly touching the shaft of his rather small penis. Then, after a moment or two, she reached in again, gently taking hold of it in her hand.

 

“Ah!” Bart murmured, twitching a little at Allison’s soft touch, making her wonder if she was being a bit too rough.

 

“Are you alright? I’m not hurting you am I!?” she asked, a look of concern appearing across her face.

 

“No, keep going! That feels nice,” Bart answered with a reassuring smile. His body seemed to indicate the same since Allison felt his boyhood begin to grow in her hand.

 

“Oh look, Lisa! It’s getting bigger,” she said gleefully, moving aside so her friend could see better.

 

“Well, try stroking it then. He likes that,” Lisa grinned, knowing full well how much Bart had seemed to enjoy it the few times they had fooled around together.

 

“Okay, I will,” Allison said, turning back to face the aroused boy. Smiling down at his rapidly hardening member, she began slowly sliding her hand up and down the shaft, feeling all around it with her fingertips. With each motion, it grew noticeably in length and thickness.

 

“Wow! Look how big it’s getting,” Allison said excitedly, “and it’s getting really hard too!” the young girl continued. Then, rather boldly, she took it within her hand and gave the now stiff rod a gentle squeeze.

 

“Oh, that feels good!” Bart moaned, reacting much more noticeably to her attentions.

 

“Does it?” Allison inquired, bringing her gaze back up to meet his. Bart nodded his approval, indicating clearly that he liked what she had just done. So, even though she still wasn’t entirely sure what she was doing, Allison began to move her hand up and down the firm and apparently very sensitive member, momentarily squeezing before noticing that it was the motioning Bart seemed to enjoy best of all.

 

Meanwhile, Lisa was a little surprised that her brother was having such a strong reaction to Allison’s touch, maybe even a little jealous too. He seemed to be enjoying it even more than when they had messed around. It wasn’t just the light moans either, Bart looked at her friend differently, not just at the space between her legs but all of her as she enthusiastically went on playing with his now seriously hardened tool.

 

“Oh my! It just twitched in my hand,” Allison cried suddenly, elated that she was getting so poignant a response from her older and more experienced partner.

 

“What! That never happened to me before,” Lisa cried equally as loudly, completely forgetting what she had said earlier about keeping the noise down. Moving in for a closer look, she could indeed see Bart was reacting totally unlike the way he had when they had done it on previous occasions. The expression on his face too was altogether different, almost as if he were in pain or something.

 

“Mmm! Aah!” the highly excited boy moaned, almost pitifully, while Allison’s hand continued massaging his throbbing erection. His breathing was beginning to labour too as it rapidly increased in pace with the level of excitement he was experiencing.

 

“Bart, are you ok?” Lisa asked, concerned for the welfare of her brother. “I think you should stop, Allison. The end is going all purple… and there are veins sticking out of it,” she said worriedly to her friend.

 

“No, don’t stop! It feels so good!” Bart puffed as he took hold of the young girl’s hand and kept it wrapped around his boyhood. “Do you think… you could do it even faster?” he asked, motioning her little hand with his own.

 

“Um yeah, sure!” Allison replied with a smile before starting to jack his bulging penis with even more ferocity. However, also noting the concerned look on Lisa’s face, she knelt down in front of him to get a more direct look at things.

 

With Bart making more and more noise, Allison continued to pump his organ, hurriedly pushing skin over foreskin. Although she couldn’t be sure, Allison didn’t see how it could be doing him any harm, not when the boy seemed to like what she was doing so much. To her, it seemed almost like when you scratched a dog’s belly, with its leg moving on its own the more you did it.

 

“Oh! Ooh!! Allison!!!” Bart groaned loudly with both girls looking up at him to see what was happening. The expression on his face was strained and he was sweating profusely now. Clearly something was about to happen, though neither girl could possibly have imagined what it was at this point.

 

Dropping her gaze once more, Allison opened her eyes wide and looked directly at Bart’s tool as she felt it begin to first swell up and then pulsate in her hand. Then, to her complete and utter surprise, moments later, a large, thick gob of white liquid suddenly shot out of the end, hitting her straight in the eye.

 

“Eeeww!!” Allison squealed, hurriedly letting go of his bulging meat, just in time for a second shot to squirt right across Lisa’s face next to her causing both girls to fall back in shock.

 

“Nnngggghhh!!! Oh man!!” Bart grunted, grabbing his still twitching member and furiously jerking it off in their direction. With the most amazing feeling he had ever experienced surging through his body, each new squirt landed somewhere on either Allison or Lisa’s naked bodies. Over and over came the warm splashes, even as they both frantically tried to wipe whatever is was from their faces.

 

Eventually though, whatever had just happened to Bart appeared to lose its vigour. With just a few dribbles oozing out of the end of his pole now, he released his hand from it and sank to the floor, breathing hard. Seeing this, both Allison and Lisa temporarily forgot their own shock and quickly moved over to him to see what was wrong. At any rate, the poor boy appeared to be quite out of it, barely even aware they were there.
