The twisted lust of her father-in-law: A thirty-something housewife, tricked into believing it was a massage that would help her conceive, has her most sensitive spots developed by a handsome masseur. While her husband is away, she is bound with restraints and subjected to a depraved threesome training session where she and her father-in-law take turns relentlessly devouring her. - Mika Sumikawa #KSBJ-446
