Two petite 18-year-olds, sisters with a secret, plot a taboo birthday surprise for their stepbrother Harper. They tease him innocently, their tiny frames barely covering their skimpy outfits. As he unwraps his present, they reveal their true intent - a shared, perverted blowjob to mark his special day. Their tiny hands wrap around his shaft, their small mouths stretching wide to take him in. They giggle and moan, pushing each other to take him deeper, their young bodies writhing with excitement.
