Chapter 5 - Lisa's Story
As the youngest child, Lisa often got left out when Dylan and Emily got to have fun. As such, she had gotten good at detecting when either of them was keeping a secret from her, and for the last week, her 'secretgraph' had been going off the charts.
So when Lisa came home from shopping with her parents and headed straight up to show her older sister the g-string that her mom had finally let her wear (though that was all Emily ever wore, and had for years), she was really surprised that upon entering Emily's room, it stank of pussy, sweat, and something else.
"Emily, what's that smell?" She asked her older sister when Emily came back from the shower. Lisa was surprised when her sister turned beet red and muttered something about "working out," but let it go so that she could show her sister her new undies.
Emily smiled at her sister's excitement at moving from 'granny panties' to 'ass floss.' But in looking at her sister's body, she knew it was only a matter of time before she broke men's hearts.
Emily wasn't that skinny, and her C-cups weren't tiny, but compared to her sister, she had a boy's body. Lisa was an inch shorter than Emily at 5'4", but it wasn't that so much as her curves that made people forget they were sisters. While Emily (and Dylan) favored their father's dark hair and skin, Lisa got their mother's strawberry blonde hair, as well as her giant tits. Emily had often wondered why the 'D-cup' gene had skipped her, especially since her little sister had had bigger breasts than her for as long as she could remember. But Emily knew her ass and legs were her best features anyway, as Dylan had commented earlier while she was riding him like a prize bull.
Lisa had stripped down and was putting on one of her new g-strings, and her "Ta-da" finally broke her sister from her trance. Emily's response was a little slow, but then her mouth opened as she stared at her sister's crotch.
"Lisa, did you shave yourself?"
"Yeah, I've been doing it for a few months. I wanted to get in shape for bikini season. I took it all off, see?"
With that, she pulled down the g-string to show her sister her virgin pussy. Emily smiled, realizing that her sister was probably dying to show it to someone. Despite her best attempts, Lisa was a virgin. Dylan had made sure of that. While he seemed to let Emily do her own thing, he watched over Lisa like a hawk. She'd had boyfriends, but due to Dylan's protectiveness and the fact that her parents had caught him and Emily in several compromising positions, Lisa hadn't really had the chance to lose her virginity. But now that she had just turned 18, she was determined to make sure that would change.
"Very nice. I love how mine feels."
"I know. Especially when you go commando."
"Lisa?!" Emily blurted, surprised her innocent sister would do such a thing.
"Well, I have those black pants, and since I didn't want to show any panty lines, I had to do it. And wow, did I enjoy it."
Emily laughed now, and kicked her sister out while she got dressed.
As Lisa, fully clothed now, headed back to her room, she thought back to the smell.
"I bet she was masturbating in there," she thought, and giggled to her self. She waved to her brother as she entered her room to drop off her clothes.
Lisa's relationship with her brother had been pure hero-worship when they were younger. It wasn't until Dylan had discovered girls and was never around anymore that Lisa began to favor her sister more, since she had cool things like bras and make-up. Lisa still had a crush on Dylan somewhere down deep, but the fact that he had been changing girls as often as socks lately bothered her more as a sister than anything.
When Lisa got back to her room, she stripped back down to her g-string, and tried on the black pants that she had mentioned to Emily. She looked in her full-length mirror, and saw that she now showed no panty line. Lisa ran her hands over her ass now, feeling how smooth it was. While she didn't have the tight ass that Emily did, Lisa stayed in good enough shape that her ass still turned heads, although it was the 'boys up front' that stole the show.
Lisa loved her breasts, and pinched one nipple now as she looked at herself. Her thoughts turned back to Emily's ass though, and the night she had spied on her sister and Jim fooling around downstairs. She had almost been caught, but the sight of Emily's head bobbing up and down on Jim's cock still filled her fantasies, as did Emily's striptease.
Lisa caught her hand rubbing her crotch now, and she changed out of her 'come hither' pants into something more comfortable, and headed downstairs. It was Saturday, and she wanted to find out if she could sneak out and join her siblings at whatever kegger they were headed to tonight. It was not long since they had their own party, and although she had spent most of her time keeping people out of the house, she had still had too much to drink, and ended up making out with some college boy before the night was over. She never caught his name though, and she was pretty sure it was a one night thing and she might never see him again.
Lisa's attention drifted back to the dinner table just as her mother asked Dylan and Emily if they had a date tonight. Both of them blushed at this, and vehemently denied it. This got Lisa wondering again. "What were the two of them hiding? They'd been acting weird since the party, but that wasn't it. Had something happened while she was off with that psychology major?"
Dylan realized he was getting paranoid about his 'relationship' with his sister. So far, only Bridget knew anything, and her memory was too fuzzy to really know what had happened. But his mother's comment tonight, combined with the looks Lisa had been giving him, had really freaked him out. Although he and Emily had agreed that this wouldn't be a two-time thing, that was only a few hours ago, and he realized how hard it would be to keep it secret. And where did Jim fit in on all this? Too many questions, not enough answers.
Emily's head was swimming with the same problems too, although she had already come to the conclusion that she would break things off with Jim. Their relationship had always been fairly casual, and she knew it wouldn't break his heart, as he would be heading off to college within a month, and although they were both going to college in Boston, her logical side knew it wouldn't last.
After dinner, Dylan and Emily decided that they were going to tell their parents they were going to a party, when instead they were going to go off for a little more 'alone time,' and try and figure things out. What complicated their plans though was that their parents signed off on Lisa going with them. That was a first, and it complicated matters.
As the three of them rode in the Jeep out to the camp on the lake where the party was being held, Lisa finally spoke up:
"Ok, what's going on between you guys? You've both been acting weird since the party. Did something happen?"
"Nothing." Dylan replied. "You're just paranoid because you're culpable as well."
"Oh c'mon," Lisa replied. "Mom and Dad figured it out already. They just don't care because we got everything cleaned up. I mean it. You guys are acting like you have a secret or something."
At the word secret, Emily's head whipped around and looked at her brother's, and Lisa knew she was on to something.
"You do! What is it?"
"There is no secret, Lisa, drop it."
"Does this have to do with Emily and Bridget doing 'Girls gone Wild' in the rec. room?"
Dylan flinched at Bridget's name, and Lisa knew she hit the bulls-eye again.
"Oohh, it does. Wait a second, where did you guys go after that? I don't remember seeing you outside, and I made sure the rec. room was empty."
Emily's blush told Lisa more than words could.
"Oh my god Emily, you were with Bridget, weren't you? Ewww, that's your brother's girlfriend."
"SHE'S NOT MY GIRLFRIEND!" Dylan roared from the driver's seat, which caused Lisa, who'd been sitting in the back seat and leaning far forward to lean back in her seat, surprised at her brother's overreaction.
"Bridget and I weren't dating. We just, um, you know."
"You just fucked her." Emily spoke now for the first time, and there was acid in her speech. Lisa opened her mouth to speak, but Dylan beat her to it.
"Yeah, so, we were both single, so what's the problem?"
"Oh come on. She only fucked you to get back at me and Jim and after that only because you've got a big cock and she had nothing better to sleep with."
