A lovey-dovey couple approached on the street is invited to a special hole-in-the-wall studio! To reaffirm their bond as husband and wife, with only her face sticking out of a hole in the wall, and watching her, the husband challenges them to a "telephone game" with a large prize! The wife shyly sticks her face out of the hole and starts the game, while the actor, who has been waiting on her body that her husband can't see, plays a naughty prank on her! The naughty wife is surprised and confused by the sudden act, but gradually becomes aroused by the actor's technique! When she sticks her face out so her husband doesn't find out, she pretends to be calm, but when she hides her face, she is climaxing with a big dick behind the wall, and the cheating wife is given plenty of NTR continuous creampies!
