My first time having incest fun was with a cousin. I was 12 and she was 10. We use to argue a lot and annoy each other. One day we were watching tv and started fighting over the remote. I would climb on her and vice versa. Her butt grazed my dick and I liked it. We continued wrestling for the remote and eventually my dick was pressed against her pussy through our clothes. Then something just clicked between us. We started dry humping wildly. We both knew what we were doing was bad but couldn't stop. We then pulled are pants down and humped each other. This continued for a few years when fam would get together. Never got caught and i still think of her nice pussy.  When was your first first incest relationship?
