Keiko, a calm and beautiful wife, will try her hand at drinking cum for the first time. Although she was confused when she saw another man's dick, he put it in her mouth and succeeded in having her first orgasm, and even though she was choking, she had her first cum. Her erotic instincts begin to come out when she successfully swallows semen through continuous blowjobs outdoors. While being tortured by many men, she gulps down the semen 10 times in a row, making a vulgar sound, and the whites of her eyes are peeled off from the pleasure.
