A special system within the school called "Service Duty" forces selected female students into an intense role: fulfilling the emotional, physical, and sexual needs of male students. These appointed girls must use every mucous membrane on their bodies—mouth, hands, nipples, and vagina—to bring the boys to ejaculation repeatedly until their cocks are drained dry. Thick, pulsing penises are thrust deep into the girls' tight schoolgirl pussies, unloading massive creampie loads. The sight of these beautiful young girls soaked in cloudy white cum embodies the ultimate pleasure.
