It all started when we were watching one of those morning chat shows, the kind with some very light news and a whole lot of celebrity gossip. There was a scandal about some celeb who had slept with his mother in law. The chat show host said, "I think a lot of men want to sleep with their mother in law."
My wife, Annie, asked, "Do you ever think about my mom?"
"No." I lied. I knew that a former boyfriend had told my wife he wanted to get her in bed with her mom and she was totally disgusted. The truth is that my wife's mom, Jane, was an 18 year old hottie when she got pregnant, and she's stayed hot ever since. Now sixty, and a little softer and rounder, she has long, dark hair (dyed, but who cares), full breasts (my wife is a b-cup at best), a narrow waist and flaring hips. Her lips were full and soft. I'd spent way too much time imagining kissing them or having them wrapped around my steel hard cock. She wears a uniform of tight jeans and colored t-shirts (sadly, high-necked), and she just has a way of looking at me with her big, dark brown eyes that says, "I know what you're thinking and I am, too."
Throughout our marriage, my wife has shared the details of our sex life with her mother. She's showed her nude photos of me and told her how much I enjoy eating pussy. Jane's husband never went down on her, ever, and hadn't had sex with her in over 10 years. Even when he did, it was birthdays and anniversaries, only. I knew Jane had a vibrator because my wife had helped her pick it out. Jane was a very sexy, sexual woman with no way to fulfill her needs and desires. She was prim enough to never cheat, even though she was propositioned nearly every time she went out of the house.
My wife is also a highly sexual woman, and we had many adventures over the years. She is a great lay, an excellent fellatrix, and my best friend. However, a chronic disease had made her take medication that interfered with her ability to enjoy sex. If she stopped the meds for a week, she'd have multiple screaming, squirting orgasms, but that week would be full of constant pain, sleeplessness, vomiting and misery. The last 12-pack of condoms I bought lasted two years.
"I think you should fuck my mom," Annie said.
I laughed. "Why would I want to do that when I have you?"
"You don't have me," she said, sounding sad and serious. "I mean, you do, but you know how I can't always be 'there' for you. I know you miss it. I miss it to, and I love it when we have sex, but I also know that once every couple of months is not fair to you. I worry that you'll want to be with someone else, someone who can...you know..."
"Stop," I said, though my cock was straining in my pants, "You know you're my only girl. I married you, not your mother."
"No, seriously," Annie continued, "This way, I won't worry that you're with a stranger, mom will finally get some quality lovin' – you know how good we are together. I want her to have that, and I want you to have that, and we'll still get together when we can. Everybody wins."
"You're crazy," I said, and kissed her. I excused myself to go to the bathroom and jerked off furiously thinking of Annie's mom.
A week went by, with me jerking off every time I showered, thinking about Jane's soft, full body. I never raised the issue with Annie, and she didn't say anything to me. Finally, on Saturday, she said to me, "It's all set. I'm taking Christy (our daughter) on a shopping trip. We'll be gone at least four hours. Mom will be here at noon."
"What are you talking about?" I said.
"Today's the day you're fucking my mom."
"I'm what?"
"You're fucking my mom. I'll be out shopping. I figure you owe me, since I'm giving you my mother."
"Uhhhh..." was all I could say, though my mind was racing.
"Relax, honey," Annie said. "It's not like you haven't thought about it. It was nice of you to lie, but she and I have both seen how you look at her when you think we can't see you."
"Uhhhh..."
