There's no other choice...

You successfully manage to convince yourself that you're doing this because there's no other choice, and not at all because you want to. Any enjoyment... and orgasm... that this brings you, is purely a side effect, and not your reason for doing it.

Still, you don't like the way that your balls are aching with desire. A desire to breed the fertile pussy in front of them.

Thankfully, thanks to the condom, that's not on the table.

...Yet.

You've delayed long enough. In fact, you can hear the tell-tale signs that the guy beside you is reaching his peak. You're wasting time.

That's the final push you need to push inside.

Don't think about the fact this is your daughter!

Don't think about the fact this is your daughter!

Don't think about the fact this is your daughter!

It's impossible. All you can think about is the fact that this is your daughter you're fucking. That, and how incredible her pussy feels.

The condom must be super-thin, because it pretty much feels like you're not wearing one. It feels like your dick is touching the inside of your daughter's vagina.

And what a vagina it is! Sparks of electric joy run all throughout your dick, and up into the rest of your body. It's the perfect amount of tightness, warmth, wetness, everything!

You almost don't hear the roars of enjoyment and laughter from above you. The rest of the world fades away a little bit, and all that exists, for a while, is you, and the delightful pussy you're inside. Your daughter's pussy. You feel a weird, twisted sense of pride for having created such a wonderful sex organ with your own genes. Combined with the sizes of your two sons, whose cocks are almost as big as your own, your children seem to have all won the genetic lottery.

The thought of genes and reproduction sends your brain down some very depraved paths. Thoughts of knocking up your own daughter with her own daughter, and sampling her pussy once she matured to adulthood herself, invade your mind. In normal times you would **** them away, deep down, with disgust. But right now, your main goal is to try and cum inside your daughter's cunt as fast as possible. So as you pick up the pace of your thrusts, you also allow yourself to get lost in the sorts of sordid and twisted fantasies that only the most degenerate of perverts could enjoy without shame.

But right now, it feels too good for shame to even enter your mind. You're fucking your daughter, and it feels incredible. You're fucking your daughter, and it almost feels right! You have to assume that it feels great for her, too. The synergy of your two sex organs is abundantly clear.

In fact... God damn, you're about to cum already!
