Fucked while sucking on dirty panties

Hi all
Ive a massive dirty knicker fetish.
My cock just goes so hard looking at them, sniffing them and then tasting them. I also like wearing them.
I have a guy who lived nearby who invites me over to do the above with his wifes dirty panties while he bends me over and fucks me. The smell and taste of the panties makes my hole open up easier than normal. I cant get enough.
I also love looking at photos of them on xhamster especially where there are photos of what the wearer looks like.
Having said all that i dont get off at all on k**s panties that just yuck.
Let me know what you think :)
