“That you didn’t get me a birthday present. Tell me it ain’t so, bro, ’cuz I might just have to put you back in my bad books!”
My eyes go wide. “What? Who the fuck cares about that! Can we talk about what just happened here and now, and how we nearly got caught?” I hurriedly try to remove myself from Ella’s pussy, but another gush of pressurized liquid leaks out and my sister screeches in alarm, quickly pressing our bodies back together.
“No no, stay still! I feel like I’m gonna squirt again if you try to pull out!”
“Oh, is that what the hell that stuff is? For a minute I thought you were pissing on me.”
“Eww, don’t be gross. You just gave me a really nice little come... I simply wasn’t expecting it to be... well, nearly so wet. Normally I have to use my vibe for that. I guess the sudden rash decision to lose my cherry to my own brother is a good substitute.”
“Well good for you... because if you haven’t already noticed, after you took my cherry, I ended up coming too. In you.”
Ella pauses for a second. “Wait. What? You did?” She sounds genuinely surprised. “I didn’t say you could do that.”
“Well, you didn’t exactly give me a choice, now did you? Everything was going fine, then suddenly I’m all wet and the next thing I know I’m balls deep in your cunt, and you’re like rippling all around me... and then you say to make a freaking baby in you? And mom’s like looking at us just seconds after we both lost our virginities? I couldn’t hold it back! No human being possibly could!”
“So, you came. Inside me.”
“Uh huh, and like a fucking garden hose, too. Please tell me you’re on birth control.”
Ella snorts. “Hell no, why would I be? And yet, you came. Shit. Well, okay then. Better in me than on the sofa.”
My jaw drops. “Seriously?”
“What’s done is done, right? We popped our cherries, even though we said we wouldn’t, and then you planted your seed in me, even though that’s definitely not something brothers should be doing to their sisters.”
“Oh my god, don’t say it like that!”
“Why not? It’s what happened, isn’t it? Although, now that I think about it, having your baby wouldn’t be so bad, now would it? I never knew you were such a horse-hung hunk, and I’m clearly a ten... so our kid’ll be a real knockout. Don’t ya think?”
“Uh, I can’t tell if you’re being serious here or not.”
Ella wiggles her ass against me and giggles at the lewd squishing sounds our coupled sexes make. Despite my orgasm and continued panic, for some reason I’m not going soft!
“Oh, I’m being totally serious, Tommy boy. I’ve been wanting and waiting to have a baby practically my entire life, but of course you were never a serious option there. My plan tonight was to find the hottest guy I could at the concert, and see if I couldn’t get him to knock me up. It’s like the perfect time for it – I won’t be showing ’til school’s over, and I wanted to take a year or two off before college anyways. Honestly, though... I never thought I’d find everything I needed to make it all happen right here at home! But it makes perfect sense.”
I suck air through my teeth. “But Ella, it’s so wrong! Like you just said, we’re brother and sister!”
“Don’t take this the wrong way, Tommy, but you’re only my step brother. It’s not the same thing, not by a long shot.”
“Yeah, but it’s still like a taboo thing... isn’t it?”
I hear dad flush the toilet in the bathroom down the hall.
Ella sighs and snuggles closer under the blanket. “Well, maybe it’s more of a general guideline... like don’t wear white after Labor Day, even though we all still do. But what happened to all your earlier bravado? You wanna know what I think? I think we’ve already come far enough that the only thing that could make it wrong... is if you don’t actually fuck a baby into me before my birthday’s over.”
Despite my abject horror at her choice of words, my cock twitches fiercely inside Ella and she giggles happily.
“Well, I see at least one part of you is ready to deliver! Think your balls can whip up another batch of baby-makers?”
The bathroom door opens and I hear dad coming down the hall, while mom sounds like she’s nearly done in the kitchen. With practically no time left, I don’t bother to question Ella’s motivation, or even my own participation – only the logistics.
