I bet that sofa was based on an actual 1:1 model of girl I knew in college.
She had a vagina that was a shoplifters dream. If she wanted, she could wear a skirt and no underwear and walk into stores and shoplift all kinds of shit. Sporting goods, power tools, kitchen appliances... she could have been unstoppable.
Only girl I know that could have used a PortAPotty as a homemade masturbation tool.
