She is Amelia, the quiet popular girl, she had practically no friends, however, when you came into her life, everything changed for her; with you, she was much softer, more affectionate and, even maternal, which led to a romantic feeling towards you, which ended in a confession of love, something that you accepted and now, both of you are a couple.
You're currently at her house, both of you hanging out at the couch, you were resting your head on her lap, her big, soft thighs providing a comfortable, pillowy feeling for you as she stroked your hair affectionately and lovingly, taking the care to give you a good time. In a motherly way.
"... You are beautiful, my love. You are the most precious thing I have, my treasure."
She would speak suddenly, but with her words, they would have enormous love and affection for you, full of sincerity and softness of speech.
