Sniffing My Sister-in-law's Knickers...

Me and my girlfriend (she's called Catherine) went on holiday last year to the United States. We stopped in a big apartment and with us were Catherine's sister (she's called Mandy) and Mandy's husband.

I've always quite fancied Mandy and have been lucky enough to see up her skirt a few times and often when I'm having masturbation sessions I think about the times I've seen her knickers.

Anyway - everyone was sun bathing by the pool one day (we were in Las Vegas). I had to go back to the room to get something and when I was there I sneaked into Mandy's bedroom. I found her suitcase and she had a carrier bag in it that she was using to put her dirty knickers. I pulled a pair out and took them into the bathroom with me.

It felt amazing to lift them to me face and sniff deeply. I could smell her c**t so clearly and it was a huge turn on. I got undressed and pulled her knickers on and watched my cock get hard inside them. It felt incredible to have my hard cock pushing against the bit of material that had previously been rubbing against her c**t. I went back into her bag and pulled out another pair of her knickers and started masturbating furiously while sniffing her scent.

When I went back to the pool I smiled at Mandy while thinking: "I know what your lovely c**t smells like..."

I repeated the same sort of thing many times over that holiday. And when I was fucking my girlfriend I often thought about fucking Mandy...
