Being shown off by an older woman

When I (f27) was 19, I was seeing an older woman who was in her late 40s/early 50s. She was sophisticated, beautiful, and well connected. She called me Chaton (Kitten) and told me to only call her Mama.

She liked me to wear short skirts and dresses when we went out and she insisted on no underwear, so that she could have easy access. She would spend the nights with her hand between my legs, edging me under the table whilst she sipped her wine and discussed art or philosophy with me.

If anyone else joined our table, she would slip her finger inside me and hold it there for the entire time.

She liked "showing me off" to cab drivers on the way home. She would ask them if they liked my dress, and watch them in the rearview mirror while she fondled me. Ask if they liked my little tits as she cupped my breasts and pinched my nipples. Sometimes, she would ask them what kind of panties they thought I was wearing, then make me spread my legs and reveal.

After an evening of playing with me, she'd be completely on edge herself. Almost immediately as we were through the door, she would be naked and on all fours ready for me to fill her with my fist.
