Realize you've made a mistake and go home
From Create Your Own Story
You know Jake is still asleep when you lock the door behind you. You don't need to worry about him finding out.
Banging your head against the frame, you wonder what's gotten into you. You don't cheat. You didn't even want sex for the past six weeks! But now you're itching, desperate. Right now, you'd do anything just to be held down and reamed like a cheap whore, taking a nice, fat cock deep in every hole at once, getting painted with cum. Then passed along to their friends.
You groan loudly. If that carny were here, you'd deck him. Or ride him... Maybe both, in turns, for the whole evening.
You shuffle miserably over to the bedroom, feeling guilty and rotten and naughty, and take a moment to watch Jake sleeping soundly.
He's a decent guy. Sure, he can be bratty and moody but he's always been good to you. And after two years, the sex was still as hot as ever. Until just recently.
More than sneaking off, you feel guilty for not letting him have you. The disturbed part of your brain goes on a tangent thinking he was entitled to you, that every time he wanted you you should have spread your legs and worshiped his dick. You want to make it up to him. But you know he has work in the morning and it hardly stands to bother him for sex now.
You try to decide what he'd want more.
