Panties
I had been dating mynow wife for about 6 months. I went with her to a wedding. She was living with her parents as was her older sister. When we got back it was late and her parents said I could stay the night. Her older sister wasn't home they said I could sleep in her room. Being horny I went through her furry laundry and found a dirty pair of panties. I smelled them and was so turned on by the smell of dirty smelly pussy. I kept sniffing and licking them finally wrapping them around my cock as I jacked off. I made sure every drop of my load ended up in her panties. I put them back in the dirty clothes and went to sleep. Took me 18 years to finally have sex with her.
The smell of dirty pussy in the underwear of someone you’re not fucking is so amazing. Someone you fancy or want and you breathe in their intimate scent. Stained creamy pussy trail and hot ass scent as you jerk off imagining fucking and eating each hole mmmm
18 years later you fucked yourvSIL?
Seems to me like you need to be sharing that sex with SIL story.
