You bought a piggy potion that makes women transform into pigs and accidentally used it on your sister .Guess it worked a little too well because while she's complaining about you hogging the tv she starts to snort and act funny. Her hands wander, touching and pinching things. She doesn't realize she's even doing it. She starts looking me up and down, licking her lips and snorting and oinking like a pig. Her english becomes broken and she seems to becoming mentally an animal! Before you can do anything she has taken off her clothing and lingerie and is riding your cock all while squealing and oinking!
