Driving home, at night, with both of us naked, after getting caught having sex.
Back in 1973, after my first girlfriend lost her virginity she wanted sex anywhere and as often as possible, so on the way home from shopping one night we stopped at Myuna Bay, Lake Macquarie. We got out and after I removed her dress, bra and panties, and she took off my pants, undies, and shirt, we got in the back seat. She was straddling me with my cock in her pussy, and going for it. We were looking out the side window at the moon on the lake when a couple of faces appeared. Looking around there were more faces at the other windows. Some young teenage boys and girls from a nearby recreation camp got to see some action. She slid off and lay on the seat and I climbed over the front seat and drove towards home naked and shaking. We stopped closer to her home where we got out and dressed and then continued home. We never got to get the happy ending that night. We had a lot of laughs, and well and truly made up for it over the rest of the weekend.
This night is still clear in my mind, and brings back great memories of her.
