I'm a married dad. A couple of days ago I was at home alone and feeling incredibly horny, so I was playing with myself naked on my bed. I had some coconut oil and was touching my ass while stroking my cock. I was feeling extra kinky so I pushed my finger into my ass and found my prostate, which I began rubbing gently.

Suddenly, someone rang the doorbell and I panicked. Was it my wife home early? A friend or neighbour? I jumped up, still completely naked, wondering how I would quickly be able to hide everything, get dressed and wash my hands of the coconut oil. I knew the door was locked though, so even if it was my wife, she wouldn't be able to come in until I let her. So I run with this raging boner still bouncing around, to peek around the top of the stairs to see who it might be through the frosted glass of the front door.

Turns out it's this Amazon delivery woman who always delivers our parcels. She's older than me, but is strangely attractive and really nice when I speak to her. I decide not to bother opening the door, and I check my phone quickly to see the doorbell camera. It's definitely her.

Suddenly, I feel incredibly turned on that she interrupted me fully naked and playing with my cock that was still out and practically throbbing in front of me. I immediately feel desperate to finger myself again. Kneeling on the bed, I didn't even bother touching my cock again, I just pushed my middle finger fully up into myself from underneath and sat down onto it. Something about almost getting caught doing something quite kinky and secretive that nobody knows made it feel incredible. It was like I wished she was watching me. I wondered how wet she'd have gotten if she had seen me and had to go back to her van to continue her deliveries.

I'm vigorously rubbing my prostate, my hard cock gently bobbing around with the movement, and all of a sudden I find myself quietly moaning to myself. I feel a massive hands-free orgasm approaching. I keep going for another 10-20 seconds and I feel it growing to a point that I can no longer control it. I let out a loud moan and literally say out loud to myself, breathlessly, "Oh my god, yes... yes..."

My cock grew so incredibly hard, swelling up to maximum size, which always happens when I'm about to have a prostate orgasm. And then a huge volume of cum started leaking out of the tip, pouring out and running all down my shaft. The crest of the orgasm takes forever; it's so intense, like I'm still going up the hill of a rollercoaster, waiting for it to careen down the other side. It's just going up and up, building and building, even though it already feels like I'm orgasming hard. It feels like it can't get any more pleasurable. It's almost painfully pleasurable, being swept up and up to the crest of the hill. And I'm just there moaning and drowning in the excitement of almost being caught.

Then it hits, and powerful contractions begins, and I'm cumming massive spurts across the bed, all over the towel I had laid down, all over my thighs. It went on forever, and I came so much I felt like my balls were completely empty afterwards. It was such an unexpected and amazing boost, almost getting caught.
