Not Funny: Playful BDSM Erotica

Bonnie's always suspected she could use a good dose of pain. Her sex life with Darren is satisfying, but very routine. She's tried to sell her husband on spanking, but he thinks the idea of adults smacking one another is a little weird. One morning, after a sexy shower, Darren surprises Bonnie by flicking her beautiful behind with his towel. She can't believe the burn. By mid-day her butt is streaked with whip wounds and she can't sit still. She places a call. Darren's only marked one cheek so far... would he mind rushing home to take care of the other?
