Later, unable to sleep again, the man hears passionate moans from behind the wall and finds himself peeking into his neighbor's window. To his surprise, he sees Mrs. Anno engaging in overtly sexual acts, a far cry from her demure daytime demeanor. The description notes that the content may vary depending on the distribution method.
