Under the Bridge

Alan's first marriage had ended in divorce as a result of his wife's adultery. A couple of years later, he met Laura. Everything about her was perfect. She was beautiful, intelligent and funny. She was also recently divorced, and he couldn't believe his luck when they hit it off. After a couple of blissful years together, they married. And then one night while visiting some of Laura's oldest friends, a throw-away comment threatened to unhinge his new marital bliss.
The subtle hint to his wife's hot past was something Alan couldn't ignore. It played havoc on his overactive imagination, and he tried to follow the breadcrumbs. Eventually, he came out and asked his new wife what her friend had been alluding to, and Laura admitted that she and her first husband used to be swingers. Alan was stunned but not devastated. Laura explained that the only reason she hadn't told him was because she knew how hurt he'd been by his first wife's infidelity.
He pointed out that the two situations were completely different. His first wife had cheated. Laura hadn't. Her first husband had not been deceived or lied to. He'd been complicit. Alan soon realised that Laura's hot past didn't just intrigue him; it aroused him. He had countless questions and the more Laura revealed, the more he wanted to know. It was probably inevitable that they would get to the point where some of the answers he craved could only be found by them both revisiting her hot past.
