Refuse the offer and continue using condoms

Were the risks really worth the reward? Sure, using a rubber was anything but pleasant and the constant friction made you sore like heck, but it was also the only guaranteed way of avoiding a pregnancy. It was an easy, clean way to control where the sperm ends up - in a useless latex sleeve. Of course, you could just tell your mother the truth about the curse, but she's had multiple kids in her lifetime - by all means, she might be into the idea of knocking up a cute teenage girl such as yourself.

"I'll pass, let's just continue using condoms," you explain, and she merely shrugs in response.

"Fine by me, I enjoy it either way, all that matters to me is having access to your twat. I don't particularly care how it's going to happen." Charming as always, but at least she accepted your choice.

While your mother walked off to prepare the sleeping bag, you make a quick trip to the car and stuff the remaining fish into an airtight bag for safekeeping. It will have to last another day after all. You give the campsite another look-over before joining your mom in the tent and getting some proper, good sleep. It appears that the idea of using condoms was enough to reduce your mother's desires, which suited you just fine...

... ...

...

Refreshed and full of energy, you start a new day! With a bit of teamwork, your mom begins preparing breakfast while you take a short trip through the woods to gather a few more herbs, supplies and firewood. It was oddly exciting to be completely self-sufficient, and without any clothes. Kind of like some **** survival adventure, heck yea!

As always, the food also turned out to be amazing. Freshly collected lemons to add flavor to the fish, some basil, and fresh chilies for a bit of kick! And again, every tiny thing was something you personally had to work for! It's what made the meal all the more rewarding to enjoy.

Afterwards, you retrieve the cherry-scented lube from the car, squirt a good amount into your cooch, and obediently bend over by the campfire without your mother even needing to ask for it. "Now that's a surprise..."

"Eh, it's... better than the alternatives, I guess." Since she didn't care about anything as long as she gets to have an orgasm, this was an easy way of keeping her tame. As usual, she slipped on a condom, knelt down behind you, and used her fingers to spread your tight lips open and insert her veiny appendage. You couldn't help but gasp at the strange sensation, it's still not something you got used to. You've seriously got something inside of you. Strange to think that girls would do this willingly, it just makes you feel **** and stuff...

As she begins pushing forward, you get the familiar feeling of how your snug, pink walls were wrapping around your mother's dick. The lube sure helped a whole lot, too. She sets into a steady back-and-forth rhythm, casually pounding into you and allowing her crotch to slap against your perky rear end with every thrust. It was... interesting to see how quickly she learned how to have sex with her new genitals. Or was it just that easy to use a cock?

Regardless, she soon moans sweetly into your ear and fills the rubber with another potent load of baby gravy. When she's done and gone, you tentatively reach down to slip a finger into your twat and smell the result - an awful mixture of cheap cherry lube and old latex. No doubt your sister would frown in disappointment at you with how badly you are treating your temporary vag. But that's just it, it's only temporary.

The following few hours are spent by the lake again, this time you weren't fishing for food but for entertainment. Every catch was swiftly released again. Eventually, the clear lake water managed to tempt you into going for a swim, and you had the time of your life! Diving, swimming on your back, jumping off cliffs to water-bomb some nearby squirrels, it was awesome!

Time flies by, and you don't even notice that the sun was already setting yet again before it was nearly dark. Back at the campsite, your mother already had dinner prepared, with a very special request. You sat down on the comfy camping chair while eating slices of fresh fish while she used the chance to speak.

"It's hard to believe it's been two days already," she begun.

"Yeah, time went by pretty quickly. It's kind of a shame, everything turned out to be slightly more enjoyable than I thought! I may even have had more fun than I did in the past," you admit with a shrug before taking another bite.

"I agree! Since it's our last day, I want to really fuck the shit out of you tonight." You cough and barely manage to swallow your current bite before you give her an embarrassed look of surprise. "Having a dick was... or is a rare opportunity, ya know? I want to make the best of it. And you should probably look forward to getting laid properly as well, it's a rare chance for you to learn what it's like for any future girlfriends you may find." Eh, true enough. "And since you're such a baby, we can continue using condoms. Even I never made such a big deal out of having to squeeze some cum out of my pussy..." she rolled her eyes at you, blissfully unaware that your cunt was dangerously fertile. And you're going to keep it a secret for a while longer.

"Sure."
