Young girls with still-immature bodies discovering adult pleasure. Their underdeveloped anuses are led into a 240-minute marathon of perverted ecstasy. Tight anal openings slowly pried open with fingers, stretched with vibrators, then pounded relentlessly by thick cocks thrust deep into their rectums. Their expressions shift from pain to drooling, glassy-eyed ecstasy as they gasp and lose themselves in pleasure. Thirteen anal girls drown in this depraved sensation.
