When you open the window, you can see the Kanda River. In this 4.5 tatami room apartment, this married woman learns about pleasure... and about love. A middle-aged teacher finds out that the mother of one of his students is posting erotic videos of married women. He calls the mother, Ai... She is a soft, plump wife... a beautiful woman with lustrous skin. He can't help but press for a relationship. He leans over her and kisses her, squeezing and licking her shapely breasts... When he thrusts his hard cock into her beautiful pink pussy, she moans sadly. But with each thrust, it becomes a cry of pleasure... He holds her down on the floor and thrusts in and out violently from behind. As she tries to come to her senses, he thrusts his cock into her mouth... She cries when he forces her to lick his cock... He makes her take it even deeper. He thrusts it into her pussy again and ejaculates a large amount inside without asking for her consent...
