Mother and daughter help brother relieve sexual tension through incest

A nerdy guy with glasses spies on his sister masturbating in the bathroom, but she notices him and complains to her mother. To smooth things over, the wise woman bends her daughter over and tells her son to stick his erect penis into her pussy. The lovers interrupt themselves for cunnilingus and then continue their incest, enjoying the process. The beauties don't forget to please the male with a double blowjob and moan voluptuously as the hard shaft penetrates their tight pussies.
