On the day of an affair, her husband spots her wearing lingerie and applying cream to her butt, and mistakenly thinks she's invited, and then cums and impregnates her and cums inside her.

[New project for an affair wife] On the day when his wife was having sex with the man she was having sex with, she was pouring cream on her butt in a slurping mood when her husband had forgotten something, and then she returned home after something she had forgotten. My wife is panicked. Her husband mistakenly thinks he's dressing sexy for herself and gets an instant erection! He thrusts into his wife's heart, "It's not for you, you know..." and cums inside her! Every time his wife becomes sexy for her lover, the husband mistakenly convinces her and hugs her. This contradiction is very erotic!
