My ex would only rub me if I wore her panties

We were never were in relationship just fwb, we came together had fun and back to the lives, one time while we were kissing and caressing each other’s body, she started rubbing my dick hard turning me on very much, and then she said stopped and pointed towards her panties and told me to wear it if i wanted to get a head, i was pretty turned on so i did what she said, and i think it was the horniest she has been, she gave me head and told me to fuck her but don’t remove her pink lacey panties.

Slowly she started escalating and once made me wear her skirt and last time we fucked, i was wearing her bra and panties in public for whole day (i put jacket on) after that our college got over and we left the cities
