Wet and Wanting

First thing in the morning she texts me, telling me her parents aren't home and she's bored
Now, I don't claim to be the smartest person in the world or anything, but I never miss a hint like that
So I drop what I'm doing and hurry over, hoping for a little action
It's a 5-minute walk on the worst day, so it's very convenient for someone in my line of work
She's engaged to some guy, amd ontop of that, her parents absolutely fucking despise me, go figure
So I have to get creative, and get in and out without being seen
So I sneak through the woods nearby, coming around to her back door
When I get there, we immediately start getting busy
I take my time with the foreplay, even though there is little need
Before long, she's practically begging me for it
All is good in the universe and everything, until I undress her and suddenly my dick falls limp
It doesn't take her long to.notice, for obvious reasons, and all of the sudden she goes from wet and wanting to.pissed
Suddenly I'm overcome with the most profound sense of shame I have ever felt
I felt like I failed her as a man, and myself
But I'm not sure how to get out of the situation, so after apologizing profusely I force small talk until I come up with an excuse to remove myself from the situation
As I leave, she acts as if nothing is wrong, but I know what she's thinking, the same thing I'm thinking
"I'm a fucking failure", I walk home in the freezing rain and reflect on how I fucked up what was probably my only chance
Now, every time I try to talk to her she feels it necessary to keep bringing up the events of that day
I fear she'll never let me live it down
