Decline, you can't take the risk

The temptation was immense, but so was the knowledge in the back of your mind that you were worried for a very good reason. Being stuck with tits, or even worse, stuck with your brother's baby growing in your belly wasn't exactly a charming thought. "T-thanks, but I'm good," you smile back at your mother, who nods kindly and accepts your decision - after all you just proved your loyalty by taking her son's seed as deep as it could possibly go. Which was another mistake that you somehow had to deal with. It was nice to see her so interested in your well being at least, you figure that you look a lot like her younger self and she took notice. You two had a similar body type even now, must be a part of the curse. For now however you need to get some things done and man up, at least as much as a girl can 'man up'... especially one who was still nude and had a cunt full of sperm.

Considering Jimmy was completely drained, in many ways, and your mom was passing the time with the TV, you used the opportunity to get up and sneak off into the kitchen to make yourself a sandwich and contemplate the situation. Pharmacy, plan B, hotel. The sooner you get it done, the better. Since most of your family was still busy in the living room, you use the chance to move upstairs and search your room for your wallet. Considering how hectic everything had been, it took some searching. Feels strange to be in there too, surrounded by boyish clothes and posters of women, from the perspective of a girl it was... weird. Fortunately you find your wallet, including enough money for a morning after pill. Good thing you got a credit card already, should cover the charges for a hotel, as long as they don't notice that the card holder has a male name.

You briefly consider getting dressed here and now and then making a run for it, but you're well aware of the pregnancy risk that your mother so kindly **** on you. Could... should... no, you must take care of that first. The bathroom was close enough, and you turn on some hot water and direct the shower head between your legs and up into your tender vagina. It was unpleasant, very much so... but you kept your legs parted for a solid minute while letting a strong stream of water rinsing out every last drop of your stupid brother's semen. Once done with that, you used a good amount of soap to clean every inch of your feminine body to try and feel normal again and pretend everything was just a bad dream. It worked well enough. Everything felt a little better.

After using a towel to dry yourself off, you begin walking back to your room... but make a turn and enter your parents' bedroom instead. May as well wear some normal woman's clothes to be more undercover out there. You gradually start getting dressed by your mother's wardrobe. Socks... panties... yoga pants... shirt... a hoodie, and you slip the hood over your head. Just as you're about to turn around however, someone grabs you by the hips and gives you a firm push towards the bed, and you clumsily fall forward and end up with your upper body on the bed and your knees on the ground. "There you are! You promised it was the first thing we would do when we come back home," you hear your father's voice from behind. "What kept you busy down there for so long?" he asks while casually grabbing the waistband of your pants and shoving them right down to your knees along with your undies. Crap! Was he mistaking you for your mother?

"Ohh, now I see. Freshly shaved just for daddy, huh? I like it." You feel his rough fingers reaching down and harshly spreading the petite lips of your pussy open to get a better look at your pink insides. The stupid medicine was still keeping your genitals aroused and wet, so he probably got the wrong idea about your willingness too. Darn it. "Bit silent today, huh? Looks like you couldn't wait for it either," he points out as he shoves a digit into your drenched lady bits and then pulls right out again. "Don't worry babe, not going to blow this load early. I haven't forgotten how you told me to save up for a week. Milk my cock the right way and you will look pregnant with the amount of cum I'll dump inside you," he laughs, but your eyes widen in shock. If you draw attention to the fact that you're not his wife, it's gonna be pretty darn difficult to explain why you decided to wear her clothes, or why you've got a wallet that doesn't belong to you. It also didn't seem like he was in the mood to take his time with this.

Already now he crouched down behind you, and before you had another chance to think about objecting, there was something blunt nudging between the folds of your pussy and seeking the tiny entrance into your body. "Ahnnn!" BIG! The massive crown suddenly plunges into you, much bigger than your brother's appendage, and you feel yourself stretching direly to accommodate it. "That's it, babe. You're extra tight today... this will be good." He's gradually burying more of his man meat inside your cunt, and it's almost painful how rapidly he's opening you up. "Mmm, I can tell you haven't used any toys for the past few days. Feels like breaking your virginity all over again." If only he knew how close to the truth that was...

He's slowly starting to rock back and forth, stretching every inch of your womanhood while you can feel each and every vein on his cock, the texture of his dick, and soon the steady slapping that his ball sack produced each time it impacted with your vulva. "That's it babe, remember what I always told you. Your little pussy is the only thing you're good for. But as long as you spread your legs on demand, I'll spoil you whenever you deserve it." Gee, your parents had a strange relationship, no wonder your mom was pervy. And nnh, your father was well endowed...

To make matters worse, he was beginning to properly fuck you, hard and deep. Every other thrust lured another gasp out of you, your soft voice filling the room while he was taking you. Again and again he pushed in, forcing you to take his bloated organ into your body.

It was a whole lot different from having sex as a guy, at least as a guy you were the one doing the penetrating. Right now, you were the one getting penetrated, and at this rate, he was also going to do an excellent job of breeding your helpless little vag. Because of what your mother had done, there was a tiny gap in your cervix, enough for a squirt of sperm to pass right through with ease. Your partner began speeding up, violating your genitals with his oversized appendage. Crap, last chance, you have to act now before it's too late! You quickly place your hands on the bed and begin pushing yourself back up, only to feel a strong hand on the back of your head suddenly shoving you right back down against the soft fabric.

"Here it comes babe, I want your pussy to swallow every drop!" He suddenly swings his hips forward, your fragile pussy lips kissing the base of his crotch while his massive organ began convulsing inside your cunt. The initial wave was just a weak splatter of precum, lubing his pipes, but then it happened. You could feel the first hot spurt of semen right up against your cervix, and another splash, and it kept on going with every throb. There's a sudden tickle deep inside, and you realize his seed was leaking right down into your womb while all you could do was burying your face in the bed covers and waiting for it to come to an end. You were truly fucked. He kept on using small pushes to milk out every drop of his vile, lifegiving seed, the sheer tightness of your vag helping to draw out everything his testicles had to offer.

It was only now that you noticed how sweaty you had become during the act, even the passive part of getting laid was... exhausting. Also, it sure seemed like you went through the trouble of showering and cleaning your vagina only for your own father to get the job done and knock you up for good. There's another trickle of hot goo leaking into you, and your dad finally exhales and collapses onto your back. "Damn... haven't climaxed that hard since our honeymoon, you naughty little slut. Your cunt was hungry today. Hope you enjoyed your creampie, babe." With sex like that, you can truly understand how your mom managed to get pregnant three times in a row before finally getting on some extra potent birth control. Your battered genitals were hurting, and you could only imagine the amount of incestous sperm swimming inside your womb with those tiny, wagging tails. You couldn't even move because of how drained you were, and he had fucked what little innocence you had left right out of you. His years of experience made a massive difference compared to what you experienced with your brother. He leaned forward and gave you a quick kiss on the cheek, luckily without noticing that you weren't his wife. "I'm gonna hit the shower." Just like that, he noisily pulled out of your pleasure slot and casually left the room as if nothing unusual happened.

Meanwhile, you're still bent over on your knees in front of the bed, face against the bed covers while your naked ass was elevated high above the rest of your body, perfectly presenting your freshly used, swollen cunt. Just an hour ago you had insisted on using condoms and behaved overprotective of your **** female genitalia. Now, the pungent scent of bareback intercourse was heavy in the air during the aftermath of getting your fun box pounded into a raw mess. And considering your daddy had creamed your little baby maker while you were in nature's best position to conceive, this may also be your first, successful insemination. Mommy would approve of the cum guzzling slit between your legs.
