Sinfully Yours (Hollywood Video)

I'm trying to find the name of a porn from the 80s. Essentially it's about a couple that sold their house and are reminiscing of memories they had there. The memories are the sex scenes

The main actress is blonde and essentially the plot is that a couple have sold their house and moving somewhere else, but they are reminiscing of the memories they had in this place.

The scenes as I remember them are:

Main blonde actress has sex with husband's sister in the shower, who I think was another blonde.

Main blonde actress has sex with a neighbour by the pool. This was the funny scenario where this moustachioed lad is "repairing a wooden fence" and comes over and says hello. He then is invited to sunbath whenever he wants by the pool so he says "no time like the present" or something like that and hops the fence. He then asks if he can do it in the nude and suggests she does the same for "no tan lines". She then says something like, seeing you naked has made me horny and they fuck. It's funny because I also remember him being hesitant of where he sets his hammer down on the set.

The couple has another couple stay with them for awhile. It then moves to a scene where they are having a dinner party and the husband gets drunk and passes out. The main blonde actress then has sex with the guest couple, who was another moustachioed lad and a busty brunette with big hair. They do it on the sofa.

The next scene is the main blonde actress with the male guest, but it is not a full sex scene and part of the plot is he finished before she was able to cum. She was annoyed by this, I think she called him a bastard or something.

Next scene is the husband is trying to sleep and finds that the female brunette guest is in his bed, while the other two are away on business or some nonsense. They eventually have sex because she's lonely.

The final scene I think is the blonde actress and her husband having sex, not as a memory but as a last hurrah in the house.

Any guidance be appreciated!
