Harlow West and Summer Renee are sick of their dorky stepbrothers, Mike and Giovanni, cramping their party style. These two bombshells start sending some seriously steamy videos to wake the boys up—think teasing, flaunting, and a whole lot of skin. But the guys? Still hopelessly awkward. With the wildest party of the year closing in, Harlow and Summer have no choice but to take matters into their own hands. Forget subtle hints—these girls dive headfirst into a wild, no-holds-barred crash course in confidence, seduction, and, well, group practice. By the end, shy geek turns into bold stud, and the foursome heat things up in ways no one expected. If you’re into taboo, wild party training, and uninhibited stepsibling action, this one’s got it all.
