I bought aphrodisiacs at a sex shop thinking I'd unwind. Just as I was about to take one, my sister dropped by! She found the pills and took them herself! Watching her, her body started twitching, she started touching and rubbing her own tits and pussy, then began masturbating! She spotted me, snatched my lips, and started sucking my cock relentlessly, then proceeded to insert herself into my pussy without a word! Even after multiple creampies, her lust doesn't subside!
