He has been living with his son and his wife for several years, and it's just the three of them - his busy son and his wife, who has such big breasts that it's hard to know where to look. He couldn't bring himself to look lustfully at his wife's huge tits, so he lived his life suppressing his lustful feelings. One day, his son went on a business trip, and he ended up spending a few days alone with his wife. While cleaning, he was excited by the sight of his wife's defenseless armpits peeking out from under her sleeveless top, and he couldn't help but bury his face in them. His wife was confused, but the smell of her sweaty armpit pussy made him get an erection, and he licked it all up. He got carried away and immediately fucked her, but she scolded him with armpit scissors and made him ejaculate... From that day on, he couldn't forget the pleasure of ejaculating while being sandwiched between her armpits, and he became completely addicted to armpit pussy.
