Please help me find a porn movie. I only have a description, and I haven't been able to find it for over five years.

I'm trying to find an old porn movie (or scene compilation) I watched sometime before 2010, probably 2005–2009. It consists of 4 separate scenes (anthology style, each scene is its own short story).

Scene 1: A brunette (looks 30+, has tattoos) wearing a bikini / two-piece swimsuit is working out on exercise equipment in the backyard of a house. Two guys wearing pantyhose masks (stockings pulled over their heads) are watching her and filming her with a camera. She goes inside, lies on the bed and starts masturbating (there is background music playing). Right after she starts, the two masked guys burst in and it immediately turns into sex — double penetration (one anal, one vaginal at the same time).
Scene 2: A girl (possibly different) is in a store/supermarket, someone is watching/following her, then sex.

Scene 3: A blonde with tattoos is taking a bath, a man is watching her, then sex.

Scene 4: A man has sex with two girls, one (or both) are tied up/bondaged (either simultaneously or one after another).Style: probably European (I suspect Private studio), lots of voyeurism, ************* / filming, pantyhose masks, transition from masturbation to hard sex, DP, light bondage. Does anyone recognize this? Title, series, actresses or studio? Thanks!
