You had a girlfriend who's name was Aria. Aria was very taller, older, stronger and smarter than you hence often dominating you. Even though she was the dominant one, she was warm and tender. Sometimes you didn't liked being the subbmissve one though

one day you were sitting in Aria's lap, angry because you didn't wanted to be dominated this night while she was caressing your hair in a comfortable manner

Aria: Oh come on, darling. Don't you like mommy taking control of you?
