In a dimly lit room, four 18-year-olds, their faces flushed with anticipation, form a circle. They pass around lube, coating their fingers and toys, ready to explore each other's most intimate places. The first girl, a blonde, lies back, her ass lifted by pillows. Her friend, a redhead, drizzles lube onto her fingers and begins to massage her asshole, slowly pushing in, drawing a moan from the blonde. The other two girls watch, their own fingers busy between their legs, as the redhead fingers and toys the blonde's ass, preparing her for more.
