It worked but...

Cassandra and Alan were in crisis. They were married for 15 years and loved each other... but these days, Cassandra didn't feel desire from her husband.
A friend of them suggested her to rent a bodysuit to spice their bed games. She choosed a young and beautiful blond. And it worked : this night, Alan became loving again and sex was the greatest she ever had for years. At the end, he even said "I love you" before saying they should rent bodies again.

During a moment, Cassandra was happy but suddenly, she realized she took back Alan's love by changing her appeareance. He didn't love for herself anymore.
