Sisters Jericha Jem and Piper Perri just can't seem to get along. After getting all dolled up, they argue in the bathroom over whose St. Patrick's Day dress is the cutest. Unbeknownst to them, their stepbrother Logan Long is hiding in the closet perving on them and jerking off. When Piper notices Logan, the girls demand that he come out. Instead of getting angry, they ask him to decide which costume is better. When Logan chooses Jericha, the girls argue about his decision. In the ensuing fight, Piper pushes Jericha backwards onto Logan's hard dick. They kick him out, but since he's their stepbrother the girls can't avoid him. An hour later, they all go downstairs to their family's St. Patrick's Day party. Neither Piper nor Jericha can get Logan's dick out of their minds, so while their parents' backs are turned they take turns lifting their miniskirts and fucking their stepbrother.Soon the girls move from competing to helping each other get the most out of their time with Logan's hard cock. Piper and Jericha take turns massaging each other's tits and clits as Logan pounds Piper's bald twat and Jericha's hairy one. Then the sisters get down on their knees and take turns deep throating Logan's big dick until he showers them with a fountain of cum. Properly sexed, the trio arranges their clothes and resume playing happy family for their parents.
