Id secretly sniff the pants of my girlfriends sister who's older than her

When i was 17 years old, a common friend introduced me to her cousin who is 9 years older then me and divorced, after chatting for a short while and having some chat about her sex life and joking about the one she is fucking. She asked if i would sleep with her as a joke and i said yes also joking. Long story short the second day directly we had sex and had a friend with benefits relation.
