Star is super curious about her sister's new boob job. Paris has been away at school for awhile and the girls are catching up in Star's room. Paris has been hiding her larger breasts from their parents by wearing baggy sweaters. Both sisters are topless, comparing breasts, when they notice their little brother (Tony) staring at them from the doorway! They quickly cover up and start scolding their little brother for being such a perv. Paris begins to reminisce on what a little perv he was when she still lived at home. Star tells her it's gone further than that now & details all the dirty ways she's been teasing her little brother, even letting him stroke it to her! Paris has got to see this, so they encourage their brother to pull out his hard cock and stroke it to his sister's breasts. Afterwards, they make him clean up by licking his cum off his hands & order him out of the room. Includes taboo, big breasts, size comparison, masturbation encouragement, CEI
