You decide to submit for now

The small bedroom is filled with the repetitive sound of flesh slapping against flesh. You're getting properly fucked for the first time in your life. And of all the people in the world who could've claimed that privilege, it's your own father who gets to explore the deepest corners of your new pussy.

It didn't take long for you to notice how your father has far more endurance than your brother did. His rock-hard cock was still plowing into you at the same familiar pace, and the smell of warm latex filled your nostrils. It's almost enough to overpower the distinct scent of your ovulating cunt that kept wafting up embarrassingly. Fortunately for you, the medicine finally had run its full course inside your blood and finished its duty completely. Any remaining thoughts you had of getting pregnant, or pregnancy in general, had been erased.

It was now entirely up to Jimmy to ensure your future safety, and right now he was missing entirely.

Every eager thrust manages to coax a defeated groan out of you since those lady parts of yours were getting really sore from the constant friction. Alas the misery is short-lived from here on out, and without even a trace of a warning you can hear your father's throaty moan somewhere behind you. He was still pushing in and out of your wet sheathe when his appendage began pulsing and throbbing and the heat of his warm semen began to occupy your loins. There was a decent amount of it too, you could feel it filling up your insides, expanding the latex-prison it's sealed in and straining against the tightness of your flesh. If not for the condom, you'd have a serious mess splattered into your little cunt...

Since you are well aware of how little he cares for talking, you don't even attempt to speak up or say anything. You simply remained put right there -- bent over the old computer chair. Even now after having had sex like this, the entire situation was simply awkward. He's more than twice your age, he's your own father, and you don't have anything in common with him. The sex couldn't be more weird... but that's just you overthinking things again. To him this was probably just a nice opportunity to try and dump a load inside a teenager. Inside you!

While he's in the process of calming down and recovering from his orgasm, you can briefly hear the bedframe in the master bedroom squeaking before it's already coming to a stop again. An even more sickening realization hits you. Did... your brother just have sex with mom? That's literally ****! That's seriou--

"There all done," your father announces while withdrawing from your tender lady parts. You glance down between your legs to see his soft, grotesque dick dangling between his legs with the condom still embracing it, a thick mixture of semen gathering in the reservoir tip. These unpleasant silent moments were making you increasingly uncomfortable. It doesn't help much that you don't really have anything else to do right now since it's not like you could just visit some old friends. Maybe Jimmy was onto something?

Maybe you should get used to the idea of getting fucked, or fucking someone, solely for the sake of killing time?

"Nice pussy, you should use it more often. Shame to let only a single guy have a go at it." Your father's interrupting remark was off-putting at first before you realize that he sure as hell is more likely to make sex pleasurable than your brother is. Before you allow your brain to think more logically you simply blurt out the first thing that comes to mind. "I guess I uh... wouldn't mind doing it again. An orgasm would be nice though, or something? We could... practice? I don't know." Like a moth drawn to the flame, the medicine your mother had given you was making you entirely ignore that you were talking to a man who already helped conceiving not one but three children. The flimsy condom had been the only thing preventing him from washing your twat with a cunt-full of sperm.

"I suppose. Even more so if your boyfriend intends to keep occupying my partner." came his grumpy words. The noises from the master bedroom had calmed down completely, they definitely finished having sex. It's an incredible weird thought. Your brother... really hooked up with your mom? "If she's busy... well then you will have to do." Your father removed the condom in the meantime and tied a knot into the thing to prevent his semen from spilling out.

"I'm sure you will do just fine. My little replacement wife." With an unsure gaze you look back at him, he's half-joking and half-serious with those words. As long as Jimmy is keeping his true wife busy, you are meant to serve as replacement? Really? "I'll go ahead and watch some TV downstairs, feel free to join me." With that said, he simply turned and left while you were still bent over the chair with your sore vag on full display. The semen-filled condom lingers on the desk in front of you, and you once again feel like you've forgotten something important...

Ah well, maybe you'll remember later?
