Yui, a normally serious young wife, is addicted to the erotic massage where her body is touched and a big dick is rubbed against her during an oil massage, and her body starts to feel good, and there are plenty of fetish shots to show her getting it on. She starts to kiss, gets penetrated with a vibrator, and even her panties are covered in saliva, so she gives a blowjob. When this is discovered, she is penetrated by her father-in-law's extra-thick dick, and even though she screams, she cums over and over again.
