There was a standing rule in our house: when I heard the shower start, I was to get a towel ready and wait for my wife to finish so I could dry her off. So when I heard the shower start, without thinking about it, I got a towel ready and walked into the bathroom.
But the site of them made me freeze. I guess I didn't think he'd still be here and certainly didn't think I'd find him in the shower in an intimate embrace with my wife.
I didn't know if I should leave or wait, didn't know what I should do. I finally decided to leave when she looked over at me and smiled. "You're going to need a second towel," she said.
Swallowing, I left the room and came back with a second towel. I stood there trying not to watch, but even when I looked away I could see them in one of the mirrors. I could see their kissing, their touching. I watched as he slipped into her, watched as they made love.
When they were done, she soaped him, cleaned him, rinsed him. When she finished taking care of him, she began washing herself while he stepped out of the shower. "Just stand there, he'll dry you off," she told him.
I felt foolish standing there in a maid's uniform, towel in hand, gawking at my wife's lover. "I...I never..."
He chuckled. "You'll learn," he said.
I approached him, dried him off from the top down. I tried to avoid his mid-section but he stepped forward. "You're doing fine," he said.
As I toweled off his thick cock, which even soft was larger than I ever was hard, I glanced at my wife, saw her as my hands worked the towel over him.
When I finished, I just knelt there in front of him, openly staring at his cock, humiliated, ashamed. "Impressive, isn't he," I heard my wife ask, realizing she'd stepped out of the shower.
"Don't be shy about it," she said, "it's understandable you'd stare."
"You did," she said, kneeling down in front of him, taking his cock into her hands. "You need to learn about these things, learn how to serve him like you serve me."
She smiled, moved towards him, took his cock into her mouth. “You need to learn about these things," she said. "Learn."
