Against The Rules(1980)

Academy cadet Mac Turner gets ravaged in the school's gymnasium showers by his coach, the incredible, towering blonde power-house, Josh Kincaid. Sex-initiate Turner recruits his buddy, fellow cadet, blonde Eric Nolte, to the manly joys of good, stiff dicks, hungry throats and willing assholes. And Nolte's an anxious pupil!
