Why would my sister put a hamster in my condom?
To help you fill it out?
To tickle your fancy?
Because she had to park it somewhere when she cleaned its cage?
Because the hamster was horny?
You and your sister have a most unnatural relationship. That you have dragged an innocent underage hamster into it, for a sick ménage à trois, is unforgivable. PETA has been notified--by the hamster, who has also retained an attorney for purposes of filing a civil sexual assault lawsuit against both of you. Additional damages will be sought for the utter humiliation to the hamster caused by your urination.
The ASPCA will also now monitor and supervise all contacts between you and your household pets.
People like you are turning A2K into a haven for pervs.
