Сводная сестра жаждет членов

Insulting a stepsister with names like "slut" and so on and alluding to friends that she is a no-good can only trigger her reaction.... maybe unexpected....but "the stepsister" in front of the three male friends of his stepbrother, having ascertained their virility, he certainly doesn't miss an opportunity to get him in his eager hole...so much for his stepbrother!!!!
