Yuri and her husband are affectionate newlyweds. She goes to a women-only work party one evening but takes much longer than expected to return, so he assumes the drinking simply ran late. Then loud, incredibly sexy moans begin leaking through the wall from the neighbor’s filthy apartment—and the voice sounds strangely like Yuri’s. Unaware that his drunken wife entered the wrong room, mistook the middle-aged neighbor for him, and is having creampie sex next door, he struggles to keep the promise that they will have sex when she comes home before finally deciding to jerk off.
