After Konatsu finds a cuckold porn video left by his friend, she mistakenly thinks her boyfriend has an NTR fetish. Wanting to please him, she shows him footage of herself meeting a man from an app, trading deep kisses, sucking his cock and eventually begging sincerely to be pounded. Her horrified boyfriend can only watch as the woman he loves happily takes creampie after creampie "for his sake."
