La Portiera nuda (1976)
Irene wisely doffs the granny-esque support bra and XL briefs in favor of pure, complete and utter nudity as she sudses up in the tub.
Irene seems a little shy, so another lady steps in and offers a hand, unbuttoning her top and letting her tots free.
She shows off nice little chunks of her right, then ass, then left, then both bangers, when getting dressed. Watch it in reverse and it looks like she's stripping down!
