You were just one of her causal intimate routines she does every day whenever she sees a man that's attractive, whatever not.

She seemed to like you very much, not just the act but you in general. Panty never considered a serious relationship whenever she had nights with men, but maybe you changed it for her to love one guy.

One day, you brought her to her "house" and into her bedroom as she laid on the bed, wearing her lingerie and her hand slightly holding yours when you laid by her. Panty was avoiding everyone and even her sister, Stocking. Just focusing on you for the past few weeks.
