GF's Moral Struggle

In a heated argument, my step sister and I clash over her conservative views. She insists our intimacy is wrong, yet her eyes wander to my growing bulge. I tease her, pushing her boundaries, as she struggles between her morality and desires. She bites her lip, her breath hitching as I stroke myself, her resistance weakening.
