Eat some berries

You greedily snatch a handful of berries and stuff them in your mouth. Mmm, you don't know if you're starving or if these are the best berries you've ever eaten. They're perfectly sweet with just a little hint of tartness and bursting with juice. You go for more, liquid dribbling down your chin.

It's on your third helping of berries that you start to feel strange. A tingling in your stomach that travels down to your crotch, and soon your cock is straining against its cloth prison. Your thoughts swim and all you can think about is how horny you are. You reach down and tear off your loincloth without a second thought. It barely registers in your foggy brain that your cock is leaking precum like a faucet, far far more than should be humanly possible. You scoop some into your mouth. Mmm, it tastes just like the berries. You need more.

You try scooping the fluid gushing from your cock to your mouth using just your hands, but it's too slow, and you can't bear how much spills on the ground, so much sweet nectar wasted. You bend over as far as you can and just barely manage to get the tip of your cock in your mouth. And so you drink, sucking ever more greedily for the sweetness you crave, no, are hopelessly addicted to.

As you suck, you feel a tightening at the base of your dick, and dimly realize that your overzealous drinking is bringing you to orgasm. Some part of you knows you should stop, but the rest of you refuses to listen as your cock twitches and soon you're moaning as your mouth fills with your own sweet cum.

You collapse into the muddy ground, excess cum dripping from your lips. You only have a few more moments to enjoy it before you slip into unconsciousness...
