As she further investigates this guys home she stumbles upon a collection of girls bound and caged.
The continental version also has other topless scenes which have clothed alternative takes in the British version - although all of those feature uncredited extras - June Powell is the only credited actress in the film that has any nudity.
I was right, she was cute and did have a great rack!! If you get enough hot party girls and guys in a dorm room, things begin to heat up real fast.
The lady in question is Sarah Porter who appeared topless in both Blott on the Landscape and The Glittering Prizes the long scene both clips have been posted on this thread, just do a search.
A 60s nudist camp film.
I'm also fondly remembering two Milfs, british actresses, getting into bed with each other, one seducing the other, with plenty of boobs on show, being watched by someone, I think, about 2002ish.
The full theatrical version was around 30-minutes long and in colour with sound and may therefore have additional scenes with nudity.
