Picked up by and had sex with a “random” guy while out walking

I told my partner I was going for a walk.

I honestly did through a local park, just wanting to have some fresh air.

But while out this random guy said something to me and we engaged in brief conversation.

He said the right things at the right time, convincing me to walk past his place.

I ended up on top of him, on top of his bed.

Just under an hour later, I arrived home from my walk.

My partner none the wiser.
