Mates girlfriends boots.

A few years ago. Me, my mate & his girlfriend went out for a good few beers. She was a sexy little blonde. She knew I fancied her. We returned back to her house. She took her ankle boots off & put them at side of the sofa where I was sleeping.
Another few beers & we all decided to call it a night. They both went upstairs. I stripped off in the living room & made my bed on sofa.
I heard them laughing & fucking. I was wanking away to every moan of hers. Then it was all over.
I gave it 10 minutes. I got a boot & started wanking away. I put my cock inside the boot, hoping not to cum. I put my cock right down to the bottom of the boot. It was tight & I could fuck her boot without holding my cock. It felt so good fucking her boot & then I shouted all my cum right at the toe end.
I thought shit. She's going to be wearing these in a few hours. I managed to clean most of my cum, but not right at the end. I fell asleep & woke to them fucking again. So another wank.
I got dressed before they came down. Everybody hungover, but agreed to go to local again. She put her boots on. I was shaking with fear, but she wasn't bothered. She kinda gave me a smile as I was watching her put them on.
Did she feel my cum on her toes ? She's never said.
