Four busty tutors with G-cups or larger take their first mixed bath with a virgin student who passed the exam! They get lovey-dovey on the bus, and get an erection when they see their beloved teacher naked in the open-air bath... Their dicks get jerked off while they wash each other, causing them to ejaculate! The teacher is also excited by the illicit relationship with the student, and plays with the virgin's dick with a blowjob and a titty fuck! They challenge the teacher with a super difficult question, and if they get it right, they get a naughty reward... They lose their virginity and have their first creampie experience, and all of them graduate from being virgins!
