It had been a great birthday. Drew's family had surprised him by throwing him a party, and his wife, Celia, had made sure it was truly a surprise. There were lots of presents, but the best one was a card from his wife. Inside had been a certificate claiming that for one evening, Celia would do anything he wanted. He knew she had meant she would go to a ball game with him and pretend to enjoy it, or let him host poker night at their house and not complain about the smell of cigars, or something like that.
They'd had a decent sex life for the 10 years of their marriage, and Celia even gave him head more frequently than most guys he knew got it. But there was one thing she had never let him do.
"I know what I want," Drew told her later when they got home.
"What?" Celia asked. She was willing to grant him anything, she thought. She prepared herself to say she would happily welcome all his buddies for a poker game.
"I want to cum in your ass." he said boldly. "You said whatever I want. And what I want is your sweet, tight little ass wrapped around my cock."
"Oh!" Celia gasped. She tipped her head to the side and looked at him. She had always been a spitter. "Don't you want me to suck your cock and make me swallow you?"
"No," he said. "I want to fuck your ass. You promised I could have whatever I wanted, and that is it. Now either you'll let me have it or I'll take it, it's your choice."
Celia looked up at Drew. By his slightly narrowed eyes and the determined look on his face, she knew he wasn't kidding. She decided to go along with him for the moment. There was always a chance she could talk him out of it. "Okay," she said resignedly.
"Good," Drew answered her. "You're going to let me do it tonight. Now take off your clothes and get on your knees facing the mirror. I want to watch your face when I slide myself into your tight hole." He watched her undress and then took off his own clothes after she was kneeling on the bed. His cock was already hard at the thought of sinking it into her ass.
