I didn't have any proof, just the occasional suspicious glances between them. I couldn't shake the feeling that something was going on between Charlene and my boyfriend Mike. I suppose that's the chance you take when you live with a guy who's ten years younger. I'm not saying I trust Mike completely, but he'd probably be hard to seduce. Besides, I overheard him once refusing to help set up an alibi so his buddy could sneak out with a woman. He doesn't know that I heard them. Charlene, on the other hand, has bragged about seducing her friends' boyfriends.
I was stewing about my suspicions one day at the gym, and a quiz show on the TV mentioned a quote from Abraham Lincoln: "The best way to destroy an enemy is to make him a friend," and I had an inspiration. When Mike came to bed that night, I put his hand on my bare pussy and asked, "You wanna do something wild?"
"You wanna make love in the pool again?"
"Better."
"On the lawn and 'forget' to close the gate?"
"I like that!" I exclaimed. "But put it on the back burner. This is even wilder."
"I've had a threesome before, if that's what you're getting at."
We were both on our sides so he could finger me. I put my hand around his waist and slid it between his butt cheeks. "So have I, but not like this one," I hinted.
He pushed himself away and said, "I'm not doing it with a guy."
"Well, that limits our options for other occasions, but it's still not what I had in mind."
"So it's another woman, but now you're just making me guess who it is." He found my pussy again and got two fingers in. "Sherry?" Our neighbor across the street is in the middle of a divorce, and she keeps telling us how much she misses the sex.
I laughed. "This is like that episode of
Batman
where the Penguin plants a bug so Batman will come up with an idea for him. You might have a better idea than I do."
"Inga," he guessed.
"Who's that?"
"One of the personal trainers at the gym. I heard she got fired from her previous job 'cause she got caught with a customer. We'd just have to be discreet."
"That could work," I said. I moved him onto his back. I tried to do a Swedish accent. "Ya, Mike, lift dose veights!" He acted like he was on the machine and pushed his arms up and down. "Oh, look vat yust slipped out!" His cock was comfortably inside his pajamas, but I fished it out and started licking it. I made loud slurping sounds while I went at it. Then I changed to my normal voice. "Inga, what are you doing with Mike?"
Mike acted like he was trying to put one over me. "Elise, it's not what it looks like!"
"Tonight's my turn, Inga!" I said. I got up on my knees and rubbed my pussy.
"Oh, ya, I'm sorry, Elise. I'll get right on dat!" I got on my back and fingered myself. "Oh, yes, Inga, just like that! Oh, you're so much better than Mike!"
Mike acted like he was pushing her out of the way. "I'll show you who's better!" He proceeded to finger me to one amazing orgasm and eat me to another. We both fell asleep with no more guessing on his part.
I found out when Charlene was available and told Mike to be ready. It was Monday night. Mike and I were waiting naked on the bed. We were fooling around but trying not to really get into it yet. We heard the front door open and close.
"Mom? Mike?"
Mike looked for his underwear and whispered, "What's she doing here?" He found them just as he finished the question.
I took them out of his hand and threw them through the doorway. Charlene walked through with them on her shoulder. "I guess he wasn't as eager as you said he was," she said with a laugh.
"He didn't know it was you," I explained.
Mike was under the covers, but he came out. "You're right," he told me. "I never would have guessed."
"And if you did, you wouldn't have dared to admit it," I added.
"That either," he agreed. "I never thought I'd do it with a family member. Well, extended family."
Charlene is 23. She finished college last year, but she hasn't found a job that pays enough for her to be able to move out. I won't say how old Mike and I are, but I wasn't old enough or young enough when I had Charlene for my age to be a medical concern.
Charlene pointed to Mike's lap. "Looks like your member's getting extended too," she said, and she lay between us.
Mike asked her, "Do you wanna hold off on the awkward part or get it out of the way?"
"What part is that?" Charlene asked. "I've seen Mom naked when we went to the Y together. Seeing you isn't awkward either."
"I'll bet," I thought sarcastically.
"Watching us together," Mike explained.
"Well, since you're already naked anyway, you may as well get started," she answered.
