Allegedly starring Ava Cadell, notes partly from memory, partly from a magazine review.
A girl is in detention at school and being made to write out "I must wear school knickers" a hundred times. Soon the schoolmaster comes over to the desk to check on her progress. He finds it more interesting to check on her breasts instead. He takes one out of her school shirt and sucks on the nipple. Then he checks to see if she is wearing her regulation knickers. Her skirt is hitched up to reveal very non-regulation wispy see-through white panties. The schoolmaster pulls them down and sits on her chair. The girl straddles him in the reverse cowgirl position, legs wide apart and, as she rides his erect penis, he squeezes her breasts. The film closes with the now totally nude girl being vigorously fucked on a school desk in the missionary position, legs resting on the man's shoulders, breasts wobbling and bouncing from the vigour of the fucking.
