Bored and alone, you find yourself drawn to your sister-in-law's intimate wear, her scent lingering on her lace panties. You bring them to your nose, inhaling her musk, your cock hardening at the thought of her. Your mind races with images of her tits, her ass, her wet pussy. You can't resist any longer, your hand finds your cock, stroking it as you imagine her sucking you off, her big ass in the air, taking you doggystyle. Your fantasy is interrupted by the sound of her returning, forcing you to quickly hide your evidence and compose yourself.
