Raven and her stepbrother Mike come from a conservative family. They don’t really know much about the world out there, and they just became friends with Kate and Enzo, two mischievous and free-spirited step-siblings who are not exactly the best influence on them. After much convincing, Mike and Raven persuade their dad to let them host a slumber party and invite their new friends. The night of the slumber party, the contrast between the two pairs of stepsiblings quickly shows up. The guests immediately grow bored with the childish games and innocent activities their hosts enjoy. Eager to shake things up, they suggest playing spin the bottle, a not-so-innocent excuse for Enzo to get kinky with Raven. Enzo becomes green with envy, but Kate has different plans for him as well in the bedroom. With the promise of giving him a chance to get back at his stepsister, Kate seduces Mike and shows him what real girls do in bed. Soon, Enzo and Kate join the sneaky lovers, turning the naive slumber party into a horny fuck fest.
