Think about how your first reaction to his cock invading your asshole is to tense up, tighten your hole even more, cry and beg him to stop, "no please it hurts." Your crying about your pain just makes his cock harder, grow bigger inside the hole he already barely fits inside, makes him want to fuck you harder and deeper in spite of your pain. This is a natural example of why his pleasure comes before yours.

Because you can't help but cry and beg for mercy, and he can't help spreading your ass open as much as he can and pushing his cock deeper inside. Both of you are just doing what you're naturally programmed to do. He fucks, you get fucked.

In spite of the pain coming from your now stretched and pounded asshole, your empty pussy is literally dripping with need. To you, it's begging for him to fuck it instead of your ass but to him, it's confirmation that you love how he's changing your new fuckhole forever. He can choose to give you some of his pleasure, play with your swollen clit to help you relax and find the joy in being an anal slut. But this is his choice, and this is a natural example of why his pleasure comes before yours.

A pause. The object inside looks nothing like what she expected. Checking the packing slip, she sees the brand she ordered - a complete mismatch to what she received. Lifting the weighty sex toy from the box, the girl is baffled at how they could have mistaken the two items. The dildo she had ordered was small and sleek. This was…

…thick, ridged, bumpy, veiny, completely inhuman. Everything her research had told her to avoid for her first. Disappointment and curiosity rumble through her as she sits on her bed, staring at the monstrous toy. Her eyes drift down the shaft. Near the base of the cock is a huge knot. She remembers feeling frustrated when she was advised against starting off with a toy like that. Of all the bells and whistles she wanted, that knot was the most difficult to let go. Now she was alone with it.

I should return it. It’s a shipping error. I should start smaller. Her hands stroke the silicone cock. I could just play with it a bit. Maybe wash it and return it. I’ve waited so long. She slips out of her panties.

Rubbing the cock against her hips and thigh, she touches her wet pussy. Seeing the dildo lying against her small frame sends shivers through her body. No wonder they said to start small. The thick, veiny cock would be a big stretch for her, even without the knot. But just rubbing would be fine…

Squeezing it between her thighs, she begins to slide her pussy up and down the shaft. Every bump and crevasse on the wicked cock makes her body tingle. Her heart pounds when she rubs her clit against the knot. Comparing the size of the toy against her petite body, she can see that if it was any larger it would reach her belly button.

Just the tip. A fib as old as sex itself. Bringing her hips over the head of the cock, she straddles the monster and touches it to her hole. The girl’s wet pussy nestles against it. The tip is already slippery from her cum. As she works it inside of her, she strokes the knot. Her favourite fantasy plays out in her head.

Something like this… would just… take me… Her hips drop as she pulls the monstrous dildo up into her tiny cunt. A sweet, squeaky moan and she rolls onto her back. The cock is thrust into her again and again, stopping at the knot each time. The harsh features make her pussy wet. It wouldn’t care, even if it broke me… Gripping the base she thrusts faster.

The girl’s toes curl as she watches the toy pound her. Through half closed eyes she imagines the horrifying creature that would have a cock like that. It wouldn’t stop at the knot… It wouldn’t understand if I begged it not to… Her nails dig into her breast, leaving long scratch marks against her chest.

Ragged breathing as she claws at her body. “It won’t fit. Stop. It won’t fit.” The girl makes it fit. She howls as the knot stretches her needy pussy to it’s limit – then cums as it pops inside. Lost in her fantasy, she bucks her hips and tries to fit the inch of cock below the knot inside her. Her finger touches a hidden button under the silicone in the base.

A faint click. Not yet at the end of her orgasm, the dildo comes to life. Mechanisms inside the toy cause the knot to grow. Vibrations run from the base up deep inside of her. The curved shaft lurches, bouncing against her g-spot. The monstrous toy fucks the overstimulated virgin. She lets out a shriek and tries to pull the toy out.

It’s no use. The swollen knot has hooked itself inside of her tight hole. Fumbling with the base, she fails to turn it off. Rolling around in her bed, she fails to remove it. The girl watches helplessly as a faint bump pushes out between her bellybutton and pussy – the head of the cock pounding her from inside.

Unable to separate fantasy from reality, she loses herself in her favourite dream. It just wants to breed you… stop fighting… make it cum… that’s the only way to make it stop… Delirious, the girl starts to rub her clit. The buzzing toy throbs inside of her. Let it breed you… let it take you… you can’t stop it… She squeezes herself as tight together as she can. It won't hurt you if you're a good hole... She makes herself a breeding slave for the monster.
