When both of them had recovered from the intensity of what had happened, Dawn unthinkingly collected the first (and largest) blob of Jeremy's semen on her fingers, and stuck them in her mouth. Only when she heard his soft gasp did she realize what she'd just done, and blushing, opened her eyes to look at him. He was plainly surprised at what she'd done, but she couldn't detect anything else in his expression: he didn't seem to be grossed out, or disgusted, or anything else – just surprised. Several seconds went by before he hesitantly asked "You… you've done that before? Tasted me, I mean?"
Dawn felt her ears burning as she reluctantly admitted "Well, um, yeah. The first time was when we both, you know… I mean, it was on me, and when I was wiping it off I just couldn't help but wonder, you know, what it, uh, tasted like. I knew how it felt, and it didn't have any smell, so I just kind of got a little bit on my finger. It didn't really taste like anything, so I got some more and tried it again. All it was was a little salty and thick; it didn't taste bad, or anything, and I finally decided that I, uh, kinda liked it, even. Since then, any time we were together, I'd just clean most of it off like you just saw."
Then, as Dawn watched, Jeremy calmly stuck one of his fingers in his mouth; it took her a couple of seconds to realize that it was the finger that he'd been using on her – and that it must still have some of her juice on it. She felt several different things – amazement, horror, trepidation, curiosity, and finally arousal – before she saw him smile as he pulled his finger back out. She lay there, stunned, until she realized that he was reaching between her legs again; apparently intending to get more of her on his finger so he could do it again!
"Jeremy! What are you doing?!" she demanded, as she closed her legs.
"You said you decided you liked how I taste. I've smelled you when you've been excited, and I really liked it, so I figured it was okay to see if you taste as good as you smell – and you do. So I was going to taste you again: I mean, if you tasted my stuff all those times, I don't see why I can't taste you some more!"
Dawn found herself feeling the pull of two different reactions: pleasure that Jeremy liked how she tasted, and mortification at letting him taste her again. For several long seconds, she couldn't make up her mind WHAT she wanted to say or do before she finally settled on telling him "It's okay if you want to taste me – but only while we're doing stuff. I don't want you sticking your finger in me like you're trying to find out what kind of pie I am!"
Jeremy was visibly disappointed, but didn't argue the matter with her.
A minute or so later, he said "Well, I guess we'd better clean up now, before the others get home."
Dawn was about to agree with him when Jeremy suddenly brightened and exclaimed "Hey, Sis! I just had an idea!"
"What's that?"
"Since we're okay being naked, and touching each other and everything, why don't we take a shower together? Maybe we could even, you know, have some more fun while we're in there…"
Dawn's first thought was to refuse, but when she paused to really think about what Jeremy had said, she realized that there really wasn't any reason that they shouldn't go ahead and clean off together. Even if they did start fooling around, it wasn't like they'd be doing anything more than what they already had, would it? Then when she imagined having Jeremy's hands moving around on her wet and soap-slick body (and her hands on his!)…
Dawn couldn't help grinning as she answered "Yeah, I think I'd like that!"
When Jeremy heard that, he couldn't help but look his sister over again, and his imagination quickly mirrored Dawns fantasies.
When she saw Jeremy's cock start growing again, Dawn knew that he was thinking the same things she was, and felt her breasts tighten. She quickly moved to stand up, and took Jeremy's hand before saying "C'mon, Jer, let's go!" before leading him to the bathroom…
Over the course of the next half hour, both kids discovered that it WAS possible to actually live a fantasy as they got much more familiar with each others bodies in the process of getting each other off again – and finally getting cleaned up.
Other than the initial nervousness, the next several of their 'meetings' went much as the first had, with a few notable differences. First, Jeremy wasn't the slightest bit reluctant to collect a goodly amount of Dawns oils onto his finger for deposit on his tongue. Second, Dawn quickly discovered that having Jeremy watching as she collected his cum for oral disposal turned both of them on – something that soon had their 'clean up' sessions becoming as passionate as their pre-shower time. The other thing that happened was that each of them began to feel as much affection for the other as they did lust. It wasn't long before both had completely forgotten any thoughts or ideas of getting any kind of advantage or leverage over the other; instead, each became more considerate of, and affectionate toward, the other.
It was a little over a month before Dawn had the idea that rather than the two of them simply masturbating each other, they could find their pleasure by each of them getting their oral pleasures directly from the other – going from using their hands to using their mouths. Jeremy readily agreed, and it didn't take them long before they were frequently (and enthusiastically) positioned with their heads at each others crotches. Jeremy quickly learned how to bring Dawn multiple orgasms; in return, she was quite willing to orally pleasure Jeremy while letting him use just his hand in return when she was starting her period.
Several weeks went by, and Jeremy and Dawn had finished a pleasant session of '69'. After they'd both gotten their breath back – and engaged in a little mutual fondling of each other – they were ready to get cleaned up. Both were still naked when Dawn opened the door to her room, and the two of them stepped out into the hallway – where they were horrified to discover their twin sisters Brittany and Bethany.
Jeremy's heart was in his throat as he managed to stammer the question "W… wh… what are you doing here?" as he tried to casually cover his cock and balls. Next to him, Dawn wasn't bothering with trying to cover herself – whether because she was female, or because they'd already been 'busted', Jeremy wasn't sure.
It was Bethany that spoke first, saying "We were going to go to Sylvia's house, but when we got there, we found out that her Mom wasn't feeling good."
Brittany followed that with "When we got home, we were going to go to our room, but when we got upstairs, we heard noises coming from Dawns room. We wouldn't have paid any attention, except that it sounded like there were two people – and that one of them was maybe a boy." Though all-but-identical twins, and close, the two girls had never done anything like finishing each others sentences or demonstrating any kind of special bond. However, it was common for the two of them to converse with others as though they were a single person.
So it wasn't unusual for Bethany to pick up where her twin had left off by telling Jeremy and Dawn "We wanted to see if we were right, and if we were, who it was."
"We never thought it'd be you, Jeremy!", Brittany finished.
Several seconds went by before Dawn hesitantly asked "Okay, so you know it was Jeremy. Now what?"
Both girls pointedly looked Dawn and Jeremy over before Brittany answered "We don't know yet. When we thought you might just be with some guy, and maybe kissing and touching, we were going to see if you'd let us learn how to kiss and stuff from him."
When Brittany stopped, Bethany continued with "But now that it's you and Jeremy, and we know you were… doing stuff… Well, we're going to have to think about it a little bit."
