You decide to walk.

You're not sure how many miles you still needed to go if you followed the road, but you're pretty sure it'll be shorter if you walk through the woods. Besides, you always hear stories about creepy murderers or whatever picking up hitch-hikers, so you'll take your chances with the woods.

You walk for a few hours, starting to regret that you didn't bring any food. You find a stream for water, which is good. The forest is pretty dense, but you can see the sun and you're headed in the right direction. Or at least, in what you think is the right direction the city.

Inside of you, you can still feel your body changing, the ache and itch in your ass increasing. Every now and then, you stop to rub your ass through your jeans, and when the ache is particularly bad, through your boxers. You whimper as you run your fingers across your hole. You can feel the wetness of the slick even through your boxers. It also feels pretty good. The websites on male Omegas you've found did mention that your ass would become way more sensitive to stimulation, and that having your asshole played with would feel as good as having your cock strokes or sucked. You wonder if that'll be true for you, or if that was just an exaggeration.

You **** yourself to keep walking. The sooner you get to the city and its medical research center, the sooner you can make sure you don't go into heat. You look up at the sky, figuring it's about noon. Since your fever started yesterday morning, you will have until tomorrow morning at the most.

You take a break near a small forest lake, and since you figure there's no one else around, you strip off and take a brief dip in the lake. You make sure to wash your ass and thighs, since the slick from your hole dripped down there. It feels good to be clean, and it feels even better to be touching your asshole without any fabric in the way. Your cock is getting harder the more you run your fingers over your hole. You tell yourself it's to make sure you're clean, and you slide two fingers inside to make sure that's clean too.

Before you know it, you're fingering yourself in the lake, the water lapping around your thighs. Your other hand is around your cock, pumping furiously. Maybe if you jerk off and come, the itch will go and you'll be able to walk for a while without feeling the need to touch yourself.

You try to keep quiet, but touching yourself feels so good! You grunt as you easily slide three fingers inside yourself. It doesn't feel like it's enough, you need some longer and thicker inside your hole. You need a big cock to fill you up.

You fantasise about that, about a big man with a big dick sliding inside of you, making you take it all, and you come with a loud moan.

As your come erupts from your cock, you look around. That was a pretty loud moan, did anyone hear you or can you continue walking without having been spotted?
