My sister sneaked into my room and secretly ate some snacks, but they were actually laced with an aphrodisiac that turned her horny! After eating them, she immediately started breathing heavily, sweating profusely, and began masturbating with a strapon right out in the open without caring who saw! The once shy and quiet sister suddenly pounced on me, took my cock in her own hands, and inserted it herself—performing shockingly bold acts I never knew she was capable of! Once a person falls this far, there's no turning back!
