In the quiet of his home, a bi-curious husband indulges his fantasies, his wife's friend's dirty panties a focal point. He teases his stiff cock with the lacy fabric, his strokes becoming more urgent. His breath hitches as he explodes, his cum dripping onto the panties, marking them as his. He brings them to his nose, inhaling her scent mixed with his, a secret pleasure he'll hide from his wife.
