Your favourite kink?

Having a woman sit on my face to orgasm, then pissing in my mouth and riding my face to at least one more orgasm.

Mine is probably size difference where the woman is significantly taller and more muscular or age play/difference, possibly

cumkiss, breathplay, just to start with most "unsual"

Taking her backdoor in a full swap with another couple or just a three some.

Being a kinky older guy and having experienced a lot in my life, I would say at this point if I had the right woman it would be...

worshipping her orally and often, multiple orgasms

eating her ass properly

begging or paying her to sit on my face

drinking her urine, in the shower

I guess my favorite kink is spanking, I love to spank a woman's bare bottom.

Spanking, belting and caning (receiving mainly).

Crossdressing.

Clothing fetish (wearing school uniform, ties, skirts and seeing other people in them).
