Gwen decides to "help" again

By the time you reach the bottom of the stairs, you can already feel your thighs getting... distinctly slick and sticky with your dad's cum. Your defeated vagina kept drooling remnants of the multiple loads he dumped inside your sore twat. It's hard to tell if you're lucky or unlucky with the way your underwear kept your cunt squeezed shut just enough to prevent all that goo from sploshing out all at once.

"Hey!" The cheerful, warm voice of your sister greets you out of nowhere and you tense up for a brief moment! When did Gwen arrive!? "So you're the new John, huh? Mom drove me home and explained the story on the way. So weird. So what's it like to have boobies? I bet you played with them, pervert. You probably even enjoyed it. Also heard some of the other stuff you did, pervy! I bet you feel silly because you pretended to be dad's girlfriend, huh?"

"Y-yeah. Just how much exactly did she tell you?" It's a relief that your sibling already knew of your awkward transformation, but it didn't make you feel any better that your mother apparently went into detail with the humiliating side of events as well. Gwen took a deep thoughtful breath before replying. "Well, she also mentioned that... yesterday I think it was? That you and dad apparently spent almost the entire day fucking like horny teenagers. It blows my mind that you're not walking bow-legged," she joked impishly which drew a blush to your face. "At least you used condoms, huh? I heard he got pretty close to popping your creampie virginity this morning, sooo... lucky you? That's the kinda taboo that's hard to come back from, ya know. Just saying. Guys hate using condoms after you gave 'em a taste of riding you bareback. I would never let my boyfriend get close to me unless he's got a condom rea--" she suddenly interrupts herself, eyes wide open!

"I mean, if I HAD a boyfriend. I don't currently. Really. Fuck, don't tell mom, okay?" Her panic was clear, though you're not sure just what's so special about her secret? She's old enough to have a boyfriend, but whatever. "Sure, yeah." She gives you a quick pat on the shoulder and retreats to the kitchen. Seems like the unpleasant chat at least lets you avoid kitchen duty if Gwen's going to take care of the cooking. Still, you can't help but wonder if she's got a point? Maybe you should've **** him to keep using condoms? It's easy to remember the times when you were still a guy yourself and had to use condoms, they remove most of the good sensations... so if your dad had been addicted to your pussy already when he used rubbers, then what's he going to think now that he had the pleasure of doing you without that latex barrier? Plus there's still the issue of you not getting any pleasure out of it. Maybe you should put a stop to it after all? Decisions, decisions...

Reaching down, you hold your hand against your bare tummy. Since you weren't wearing more than a bra above the waist, you could easily rub your flat hand against the taut, smooth surface of your naked stomach. Weird to think that the area just underneath your bellybutton was completely stuffed full of your father's semen. Right now the only hint at the forbidden adventure of yours was the subtle bulge that highlighted where most of his spunk was trapped inside your womanhood. Daddy's precious gift in exchange for the 3 orgasms you coaxed out of his weary testicles! The term cumdumpster comes to mind. Ugh...

A few more droplets of his spunk manage to leak out of you and you quickly decide to leave the hallway and sit down in the living room. Of course you lift your legs high up and onto the table while leaning your back against the couch -- with your thighs so close together and your feet so high up, it once again prevented the mess from becoming worse. It still hadn't occurred to you that allowing his cum to rest inside your belly was one of the worst things to do right now! It's basic biology that after a successful insemination, the only remaining factor was time. Time that currently wasn't on your side! Almost a billion tiny sperm cells -- each one full of your father's incestuous DNA -- were occupying your loins to try and make a baby...

"Let's see if there's anything interesting on TV," you mumble to yourself while switching through the channels. Now that you finished fucking your dad, you were once again tied to a sensation of boredom. Meh. Eventually you manage to get through another hour before dinner is done and you join the rest of the family at the dinner table. By now, your panties felt completely soaked through and damp! As far as you can guess, the only reason for why your mom didn't pick up on the distinct scent of unprotected sex that surrounded you, was because she must've had another quickie with Jimmy. She probably assumed that it was her fault that the room carried the obscene smell of intercourse! She thought she's the only one who still has the privilege of getting laid. She had no idea that you, entirely out of spite at her, allowed your father to take you bareback -- repeatedly. It's HER fault for allowing your stupid brother even a trace of pleasure after the bullshit he tried to pull off. Solely to get back at her you were now sitting at the dinner table with your cunt full of her husband's sperm. At least your vagina was being used for something positive, right? She's stuck with your stupid brother.

Needless to say the family dinner was rather quiet and awkward. It was tempting to make a joke about moving to live in Alabama because of the sheer amount of **** recently... roll tide.

As you attempt walking back to your room, you're approached by Gwen in the hallway! Comes a little out of nowhere considering how much she tried to avoid you just an hour ago. She had that familiar expression of curiosity and a need for answers, strangely enough. "So?" Her eyes are fixated on you. "You didn't answer me earlier! I still had a whole lot of questions!" You tilt your head in surprise, what does she want now?

She pulls you into her room and shuts the door. "Well? I mean you had a whole lot of sex, so I assume you enjoy being a girl then? More so than being a guy?" Her gaze is burning into -- is she trying to figure out which gender has the better deal? You're trying to think of a good answer. "It's certainly easier, I guess. I can just lie back and let fathe-- I mean let the guy do the work, you know? But as far as pleasure is concerned, it's waaay easier to get off when you've got a dick. You just gotta stimulate the shaft and that's it, good to go." It's the honest answer. Male equipment is way more simple than the female stuff. It's just that the female stuff has way more potential... assuming you bother to push the right buttons.

Gwen nods along with your explanation. "So you rarely climax, is that it? Is he hitting your G-spot at least? How many positions have you tried?" Her questions are quickly overwhelming! "Hold on, what? I thought the G-spot was a myth?" you inquire with a raised eyebrow.

"Hmm... into how much detail should I go?" She takes a seat and gestures for you to sit down on her bed. "Just hit me with it, I'm sure it can't be that complicated." You're certain she's got nothing new to tell you anyway. After all you believe yourself to be pretty confident in terms of anatomy. Especially now that you're a proud owner of a vagina yourself. At least until you change back into a man.

"Okay, sure, full detail then. It's still a tiny bit of a mystery but not completely, so here we go. You've probably heard that some girls can only climax when playing with their clit, right?" You nod in response. "Doesn't that apply to all girls? I thought that it's a joke or a prank when some girls say they can orgasm from sex alone. You know, without touching themselves during it."

"No no, well... yes? Thing is, every woman is different. For one, a woman is going to have a hard time enjoying herself if she doesn't even know what she enjoys, or if she can't relax, right? So that's the first key, just let go and allow yourself to have some fun. The second part is the important one however, every clitoris is different as well! And more intriguing is that the clit isn't just the little fun button on top of the slit, it's all part of a slightly larger organ, kind of like a triangle? So you don't have just the sensitive bit on top, but there's also sensitive stuff to the left and to the right as well! Kind of like a hidden labia, but on the inside, and obviously more sensitive. That's why many women care more about penis girth than length, since girth makes it more likely to stimulate the interior part of the fun bits."

"... what?" This is entirely new to you, or perhaps it's a prank? She did look serious so it's hard to tell. "Okay a more simple explanation then... pretend that the clit is a snake. The part you see outside the vagina is just the head of the snake, but there's an entire snake-body around the inner part of the vagina that'll eventually wrap around a cock."

"So then why doesn't every girl climax from sex if... if the insides of a pussy are somehow connected to a part of the clit?" This is oddly confusing, and sure as hell wasn't in any biology book you've read.

"Because like I said, every woman is different you dummy! For some women, the invisible part of the clitoris just isn't developed enough, or not sensitive enough, who knows. A majority of women can't get a climax just by getting stuffed with some guy's sausage. So the women who can get an orgasm from penetration, who talk about having their G-spot getting hit, are lucky enough to have just the right layout on the inside. The other half of women will have to stick to button-smashing to get anywhere."

It's all a little hard to believe, but all right. "So it's all just a matter of how things are on the inside... the layout? And some girls are simply lucky enough to have a clit that SOMEHOW gets stimulated just by getting penetrated and stretched?"

"Yeah that's the bottom-line. Of course it still feels nice for almost every girl to take a dick, but the difference in sensation is... hmm... since you are a guy, you can probably compare the sensation to either having just the shaft of your cock touched, or the super sensitive crown of the cock! Both feel nice but one is probably far more enjoyable, right?" She's beginning to make more sense but you still don't quite get where this is going?

"So what's your point?" you finally ask her, bluntly. While you're still seated on the bed, she retrieves a little vial from one of her drawers and places it on the palm of your hand. There's some purple fluid inside and it's cold to the touch? "Since you don't plan to be a woman permanently anyway, you could try that potion! It's got some strong hormones and should improve whatever situation you've got going on downstairs. Should make things more receptive, easier to stimulate! It's not going to change how your body looks, just how it feels. If you're lucky, you'll join the club of girls who really enjoy penetration!"

She hadn't noticed the dark, damp spot on the front of your sweat pants. Your father's sperm was still working its way deeper inside. Whatever enhancement the potion offers could very well become a permanent addition if you don't manage to return to your original body. Do you really want to be stuck in the body of a girl who can easily climax? At least she gave you a decent scientific explanation for what the potion would do to your body. It would simply fix a tiny flaw, really. Considering you are way too lazy to play with your clit during sex it sure would be nice to have fun without even having to touch yourself.

According to your mother's explanation, it should soon be really easy to switch back into your original body regardless of what you do... you playfully juggle the small vial back and forth between your hands. Are you in the mood for a drink?
