Anyone know this late 70s film?

[Bart]

I'm trying to find out the name of a film (and find) a film I saw in about 1982.

The storyline was so bad it was laughable. However, what I remember is:

It was HC
It was British
It featured models who appeared a lot in playbirds / Whitehouse etc
There was a scene where I think burglars have a scene with a mother and daughter/ next to each other.
There was a scene in a jacuzzi between a brother and sister (!)
There was a tacky strip scene in a a nightclub.

Thats not much to go on, but if anyone can help I'd be grateful.

the bitch or the stud?

Sounds like The Sex Thief, 1973

Infamous for having Diane Keen in it (and Christopher Biggins!)

Hardcore version known as Handful of Diamonds had inserts (literally) added for US release. Quite well done as it looks like Diane does h/c.

sorry missed the 'HC'

chris biggins in a sex film?

Thanks, but thats not the one. I would say it was made between 79 and 81, and definitely had no inserts (if you know what I mean).
