Beautiful, shapely Rui lives happily with her well-paid construction-supervisor husband until delays on his project leave him facing a huge compensation claim. To protect him, she offers her body to the client. After discovering how good her pussy feels, the man demands more, waving money in front of the watching husband as he takes Rui again. Her enormous breasts bounce while she moans on a stranger's cock, and the wife is ultimately reduced to convenient sex property used to repay the debt.
