Walking into her room it hit me immediately that she was in heat.

That actually held me in pause before I saw the state of dress, or undress, I corrected mentally.

She gave me a coy smile before telling me about how we had been dating for the last 4 months and that today she started her heat.

Im smelling this and my pants are starting to tent already while im thinking, Duh!, as shes talking about it.

When she mentions shes thinking about going to "home base" with me to sooth the itch, all i can focus on is the scent, her swollen pussy,.. oh, and her words as well, i think, im following with the correct head and mental reasoning and stability.

Its fucking hard though...

Im leaking pre in my pants, shit.

After i finally come to a bit of reality and mind returns from orbit, she looks at me with those beautiful eyes and I sense danger.

She has always had a competitive spirit but the look she was giving me, i swear, made my balls draw up in self defense mode.

She laid out the wager.

We were going out front, and we would race from her house to our favorite pier on the beach, and the first to touch the lightpost at the end would win.

I asked what are the prizes, knowing, hoping, and the twitching thing in my pants about to burst out was thinking too - and the looser?

She smiled and said it was simple, If I won, I could use her pussy however, wherever, and whenever i wanted within reason for the whole month of February.

The ancient part of my brain still of reptilian nature almost just made me blurt out your on!

But then the sensible part of my brain pulled the reins on that.

And if i loose? I said.

Simple she said. You have to spend February in a chastity belt, no fap, no pussy, no touching.

How are you going to deal with your heat I postulated, hoping it would make her rethink the belt thing.

Oh, i have a favorite strapon, and one of my girlfriends would not be in the slightest bothered to help a sister out.

And she adds, shes going to use it on both of us.

At this point, as my mind crunches what is laid before me I figure out an angle on this.

Thats not fair - I get denied and learn how to take a dick up my ass, but I can only get your pussy?

I smiled now.

To be even, I win, i get access to any hole and the use of your paw as well.

She nodded and said Fair.

I thought about the odds now.

It was about two miles from here to the Pier.

She was a prolific jogger and had great stamina for distance, but at a slow/moderate pace.

I was a distance sprinter and won state this year, so I could run fast at a high intensity but not long distances.

I think it was a fair matchup in the challenge.

I agreed, she agreed, and we lined up out front and were off.

That first week, I learned something new - you can come from being fucked up the ass...
