A couple of days pass.

The next couple of days are full of glorious fucked up sex. That afternoon Carrie rode your cock while you shopped for fertility stuff, you buy online tablets to increase hormone release, an injection to increase the likelihood of her releasing multiple eggs and a product called WRIC.

It was an injection which works with humans but was designed for fertility with breeding horses. It was never approved for human sale as the side effects were supposed to be a little ****. Additional breast tissue growth, swollen ovaries and an increase in some hormones which would cause an increased sex drive.

Seeing as two of the **** were injections Carrie was adamant she wanted to have one shot into each of her tits. Not being one to argue with playing with, or abusing her tits you were happy to comply. Just when you thought you were done online Carrie switched to some porn and rode you till you couldn’t cum any more, everything she looked at was taboo breeding, cheating sluts, interracial, ****. She must have come ten times.

The next morning while you were fucking her doggy style she apologised for not being a good breeding whore, that she wasn’t fertile and begged you to punish her. You happily complied slapping her arse until it was red and purple.

That afternoon you went out with her to a tattoo studio, unable to decide what kind of tattoo to get you got both her nipples pierced instead.

Carrie was complaining about how sore her nipples where when you were getting home but she stopped mid sentence as she saw a box at your front door. “They’re here.” She was looking flushed and squeezing her legs together, she then turned to you “Can you please fuck me while injecting my tits with **** to make me pregnant.”

You laugh as you pick up the surprisingly heavy box, “I thought your tits were sore?” You tease.

She nods, “They are, but they will be more sore when I am eight months pregnant with twins while being gangbanged by your family so I should get used to it.”

As you put the box down on the table you turn to her, “My family huh? You don’t think your brother is going to try and bang you?”

She tears the tape from the top of the box and laughs, “Silly, who do you think gave me the twins?” she jokes.

Both the injections came in an esky so you drew some medicine into two syringes before putting it in the fridge, when you turned back you found Carrie kneeling naked in front of you with three tablets on her tongue.

“I thought it was one tablet a day?” You say as you undo your pants and pull out your already hardening cock.

She gives you a few slurps and then swallows the tablets as she deepthroats you, using your cock to push them down. When she pulls back she looks up at you and smiles, “Yep, one a day, but I want them to work faster so I can no longer be a useless breeding slut and start being a very fertile breeding slut.

It’s hard to argue with that logic, especially when you can see she is ready to pounce you and is dripping with arousal.
