Window Treatment — Ellison James

When Wendy Parker mistakenly sees a sexy man naked in the apartment across from hers, she is strangely drawn to continue watching, against her sense and better judgment. She hides in the darkness of her apartment as the couple across from her make love, and is so turned on by what she sees that she must pleasure herself to release. When she is finished, she discovers that the couple across the street have turned the tables and are now watching her!

What starts out as simple vengeance for being discovered in such an intimate moment, becomes an extended game of one-upmanship as Wendy becomes enthralled in the world of voyeurism, exhibitionism, and mutual masturbation, until she's included her boyfriend, and numerous props and toys.
