I had a bit of lust for cousins, but most of my stories otherwise I've told before and not going to rehash. Nothing directly juicy... or even really consenting.

But one classic is I used to webcam with gf and she'd steal and use her mom's toys all the time. It was hot in general, but making her suck on that pink dildo and know her mom's juices were on it turned me on so fucking much. Not to mention them both cumming on the same toy. Mom getting her daughter's arousal inside her, never knowing.
