DVAJ-707 | A father-in-law who suffers from impotence gets a full erection for the first time in six years when he sees his wife's body. "This might be the last time I get an erection, so let me put it in just this once..."

The reason her mother-in-law, who lived with them, left home was, surprisingly, her father-in-law's impotence... The two comforted her grieving father-in-law by working on exercises to improve his erection, but it didn't work and he became desperate. Unable to bear the sight, Serina gave him a groin massage, and her father-in-law's penis, which hadn't gotten hard no matter what she did, suddenly grew bigger and he had his first full erection in six years!
