[M4F] How I stumbled upon my very own pet girl

Twenty past seven. I've not finished the report, but I've finished enough of it to finish it off in the morning. Before anyone notices I've missed deadline. I stare at the words and figures for a beat before leaning in to turn off the monitor. Sigh. Standing to get a view over the cube walls, it dawns on me I'm the only person left in the office. Probably not unusual. Not because I care more than the other people about this dead end job, but because I have no where else to go or nobody to come home to. What difference would an extra hour bouncing off the walls at home make?

I grab my coat and bag and head to the bus stop. It's raining. Not hard, but the kind of rain that makes you a little damp. Coupled with the fact it's dark makes for a wonderfully depressing scene. It was dark when I came into the office too. I've not seen daylight today, which reflects my mood perfectly. The drudgery of day to day in a mildly depressing meandering life. As I waited I pondered if I was just going through the motions of life. And I conclude I am. My old life was better. I should have tried harder. I've come to terms with being in purgatory. This is my punishment.

Arriving home, I hang my coat and drop my bag. I figure I'm not damp enough to warrant changing, so I head to the kitchen for whatever leftover takeaway I had yesterday. Oddly, the kitchen seems cleaner than when I left it. I can't put my finger on exactly why though - Everything is where I left it. But everything seems less.. grubby? I shrug it off and find something low effort in the fridge.

After an hour or two wasting yet more life in front of the TV I head to bed via a shower. Standing nude in front of the bathroom mirror, I come to the conclusion that I'm going to need to do something about my weight. I'm not fat, but I'm certainly not as slim as I was in my 30s. The good ol' days. I dry off and head to the bedroom.

I fumble around for the light switch and flick it on, illuminating the bedroom and revealing a girl lying on my bed. A stranger. Adrenaline is suddenly squirting through my system. Am I about to be robbed? I freeze. Unable to move. My eyes taking her all in. The pair of thigh high black socks. The big T-shirt covering everything else. The little peep of bare thigh between the two garments.

She's pretty too. Happily looking up at me with doe eyes and a welcoming smile. Her head is propped up on her hand and she's blinking as she got used to the light. She readjusts slightly. A move that hinted at the fact there was nothing underneath that large oversized T-shirt she was wearing. Wait, was that my T-shirt?

Who is she? What is she doing here? I begin to speak, but the words aren't coming out. The girl reaches out towards me and reaches toward my cock...
