Innocent teens, untouched and pure, find themselves in a twisted initiation ritual. With no clue of what's to come, they're ordered to strip and service their older siblings.

Their tight, virgin pussies drip with excitement as they straddle their new partners, feeling every inch stretch and fill them for the first time.
