My Mother-In-Law, Part 3 -- Conclusion

Written by silent killer

It's been a while since I've written about my exploits with my mother-in-law, mostly because there hasn't been much to write about that you haven't heard before. Once in a while, sometimes as often as once or twice a week, I'll go over to Joanne's house on some pretext and we'll fuck as much as we can before I run out of energy. Then I'll go back home and try to recharge my batteries so that my wife Cathy won't notice something's wrong.
Despite all my struggle to maintain a normal sex drive, I still had occasions when I couldn't get it up with Cathy. Fortunately she didn't suspect me of cheating on her, but she did propose that we try to add some spice to our sex life.
I bought some toys for her and that helped. I also cut down on my irregular visits to her mom's house, which helped a lot. But Cathy wanted to try something else which I never thought she would be interested in. She wanted to rent some porn videos and watch them.
I let her pick out the videos, and all the ones she selected had lesbian scenes or man-with-two-women scenes. It didn't take long for me to ask her if there was some fantasy she wanted to fulfill, and after only a few hours of teasing sex, Cathy finally confessed that she wanted to sleep with a woman.
You can guess what my first thought was. If only I could get her into bed with Joanne! But I realized that was impossible. A lot of other options were ruled out too, such as going to swinger bars or advertising on the Internet. In the end, Cathy and I decided to pick someone we knew and bring them in. And Cathy told me that I had to do the picking.
A couple of weeks after this big decision, I was in Joanne's bedroom wrapped in a 69 with her. After Joanne came, we changed positions so that she could easily suck my cock to orgasm. I held her head and thrust deeply as I filled her mouth with cum.
We shared a beer afterwards and I told her about Cathy's fantasy. A nutty gleam came into Joanne's eye immediately but I told her to forget about it, there was no way that Cathy would want to have sex with her own mother.
"Well, Pete, there's a couple of things you don't know about," Joanne said, grinning madly. Then she told me this story:

After I had first divorced Cathy's father, I had to move into a small one-bedroom apartment in a crappy neighborhood. This was when Cathy was about eleven. We had to share the bedroom and the bed, and we shared the bath or shower too sometimes. I'd seen her naked a lot -- I'm her mother -- and she'd seen me too, but under the circumstances in this tiny apartment we saw a lot more of each other, especially when summer started. There was no air conditioning in this place. We had a lot of fans and a lot of ice in the freezer and that was about it. So we'd sit around wearing basically nothing for most of the summer.
At night we'd just sleep naked, and that was, you know, pretty innocent. Even when the questions started about the differences between our bodies, that was innocent, too. But one night she suddenly discovered diddling on her own and she kept me awake for a couple of hours while she experimented with herself. So finally I rolled over and turned on the light and talked to her about it, and I showed her how to do it right.
First I showed her on myself, then I showed her how to do herself. And then we just laid there masturbating together. I came a couple of times and she finally finished. Then we turned the lights off and she went to sleep. But I stayed up thinking about it.
The next night we both just started doing it after the lights were off. And I couldn't help myself, I just reached over and did it for her, then I showed her how to do it to me. And afterwards we just went to sleep together, like in each other's arms. Like lovers.
After that I saw her in a new light, like a lover. I became jealous when she went out. If one of her little friends came over while we were barely dressed, I'd think she was showing off. I never brought dates home because I was afraid Cathy would seduce them.
At some point we had progressed to where I was, uh, going down on her, and she was sucking my tits and diddling me. I shoplifted a vibrator and we used that on each other.
This went on every night for a long time, long after she started developing. I was so happy to see her breasts growing. And she started getting pubic hair, and we would get up in the morning and shave each other's pubic hair. And we just kept at it, having sex every night, for like four or five years.
When I finally had enough money to get a house, Cathy had her own bedroom. The first week, we slept together every night. Then I brought my boyfriend at the time home and Cathy stayed in her room, and then after that, there was nothing else between us. It was like I broke up with her or something. There wasn't any tension, though I missed doing all of that with her. And I still miss it, Pete. So there's gotta be some way we can work this out, OK?

I sat stunned by Joanne's story. Stunned and fully erect. She had started jacking me off about halfway through the story, and now she said, "Think about it, OK?" before she took me in her mouth again. A few minutes later she was on her hands and knees draped over the bed and I was fucking her again, turned on beyond belief at the prospect of seeing Joanne and Cathy fuck.
A couple of days later I finally came up with a solution. I told Cathy that I had a woman who wanted to make love to her, but she wanted to dominate Cathy. I suggested that Cathy should cover her face because this was a woman I knew who didn't know I was married, and I wouldn't want Cathy to meet the woman outside of this single encounter and know who it was, and vice versa.
"It's going to be completely anonymous?" Cathy asked.
"At first. If the two of you are compatible we can let it go further if that's OK with you."
Cathy nodded. "Sounds good. Thank you, baby, for doing this."
"No, thank YOU," I said, opening my pants to reveal my hard cock. "I love the idea, as you can see."
We fucked right there in the living room and my cum left a small stain on the couch cushions.

A few weeks later it was all ready to come together. Cathy and I were in a motel room waiting for Joanne to show up. I had tied Cathy to the bed and wrapped a bandanna around the upper half of her head, concealing her hair, eyes and nose. She looked pretty anonymous.
Earlier in the day I had told Joanne when and where to meet us, but I had also instructed her to go out and take a shower using brand new soap and shampoo of a brand she had never used before. I also told her to buy some cheap perfume that she would otherwise never wear. I knew that Cathy would recognize her mother's scent and so we had to work to mask that scent. On top of all that I told Joanne to stop off in a bar somewhere on the way to the motel and have one drink while sitting next to a smoker. Because Joanne didn't smoke, this would further mask her olfactory identity.
I put on some music and gently stroked Cathy's body while we nervously waited for our guest. To Cathy she was a perfectly anonymous woman who was simply interested in having a dominant lesbian affair while some guy looked on and beat off. To me, it was Joanne, my mother-in-law, my wife's parent, who would in front of my eager eyes engage in passionate lesbian incest.
I couldn't wait. I was giddy with excitement and nervousness. Cathy was a little scared and pretty aroused. And when Joanne showed up, locked the door behind her and opened her trenchcoat to reveal a strap-on jutting out from her completely nude torso, I nearly came on the spot.
Cathy murmured, "Is she here? Hello?" and as an answer, Joanne leaned over and kissed Cathy's mouth briefly. At this point Cathy stopped speaking English and her vocabulary now consisted entirely of guttural grunts, sensuous moans, and sharp intakes and explusions of breath.
Joanne untied her daughter's legs and climbed on top of her. Cathy wrapped her thighs around Joanne's waist as Joanne fumbled with inserting the strap-on for a moment. Then she was in, and she slowly sank the tool deep into her daughter's cleanly shaven cunt as Cathy sighed and burbled. Joanne leaned over and took one of Cathy's tits into her mouth as she started to fuck her.
I got behind them and pressed my cock against Joanne's ass, whispering "May I?" Joanna looked back at me and nodded vigorously, opening her legs a bit and halting her slow penetration of her daughter. After a few minutes and a liberal application of KY, I was able to get firmly planted in Joanne's ass. The three of us started crudely fucking.
I cannot begin to describe the hot excitement that I felt as I fucked my mother-in-law who was fucking her daughter at the same time. It only took me a few minutes to build up to a tremendous orgasm which I promptly unloaded into Joanne's buttery smooth rectal passage. I slowly dismounted and sat next to the big bed so I could closely observe the remaining proceedings.
After Cathy had cum twice (I think, maybe thrice?) from being dildo-fucked by her mother, Joanne disengaged herself and removed the strap-on. Cathy was breathing loudly and groaning as if she was being massaged by a team of weightlifters. She was twitching a bit, caught in the throes of postcoital pleasure.
Having discarded the strap-on, Joanne squatted over her daughter's face and pressed her bare cunt lightly against Cathy's eager lips. The sight of my wife's tongue gingerly exploring her mother's pussy was more than enough to renew my erection. I decided to plant my pole into the hole that my mother-in-law had recently abandoned, so I squatted between Cathy's spread legs and dipped the swollen glans of my cock into her sloshing wet cunt.
As I fucked my wife, I watched as Joanne reached down to force Cathy's mouth open, then emitted a few strong spurts of clear, sweet urine into her daughter's mouth. To my surprise, Cathy squealed with pleasure and quickly swallowed the offering. Joanne glanced back at me and smiled that infamously evil smile, then unleashed the remainder of her bladder's content. The majority of the urine splashed across Cathy's neck and chest or leaked out of her mouth to run down her cheeks and stain the pillows, but my wife was still struggling to swallow as much as she could.
Joanne noticed that my fucking speed increased, so she laid down next to Cathy and began kissing her passionately while motioning for me to ejaculate onto their faces. I pulled out of my wife's cunt and scrambled to the top of the bed where I could place my cock between the two women's lips. Their tongues swarmed over my shaft as I stroked myself until I was ready to cum. This being my second orgasm in less than an hour, I was only able to issue several large streams of watery cum instead of the usual energetic chunky spurts.
When I finished, Cathy was still holding her mouth open and waggling her tongue and squealing as if she was a hungry infant. I intrepreted this as a demand for more hot piss, so I emptied my bladder across the two women's faces. They both cooed and sighed and tried to swallow as much as they could while I simply struggled to commit this sight to permanent memory.
After that the three of us were pretty much drained. We laid there for several minutes in silence except for Cathy's soft moans as Joanne and I quietly stroked her sticky, stained body.
Cathy finally decided to speak English again: "That was wonderful."
Joanne and I froze and stared at her without saying anything.
"Can I be untied now? I need a shower."
Joanne and I jumped off the bed. I threw the strap-on at her and she missed it completely so it clattered on cabinet across the room. She threw on her heels and trenchcoat, wiped her face with a corner of the bedsheets, then seized the strap-on and tucked it into her pocket. She kissed me quickly and lingered over Cathy's face, nearly choking her daughter with her passionate probing tongue. Then she left, slamming the door behind her.
I unmasked Cathy and then untied her. "She didn't want you to see her face or her body," I said, thinking quickly. "She's very insecure about her appearance."
"Why did she let you see her body, then?"
My mind shifted into high gear. "Oh, she knows that men find her attractive, but she thinks women judge her because of her, uh, voluptuousness."
Cathy sat up, wiping her face and rubbing the rope marks on her wrists. "She did seem like she was very well endowed."
"Well, she has kind of a pot belly too, and wide hips. Men don't mind that stuff, but ..."
"Let's take a shower and then talk about this," Cathy said, heading for the hotel's bathroom.
I waited until she had gone around the corner and started the shower, then I did a little victory dance and silently shouted "Yes!" to myself in the mirror. I had done it.

That was the only time that Cathy was interested in doing that. She said that it had been great, but doing it seemed to purge the fantasy from her system, so she wasn't interested any more, no matter how much I begged (and how much Joanne begged me to beg).
I did manage to pry her incestuous history out of her. After a long night of drinking I told her about a distant uncle teaching me to masturbate, a true story that was nonetheless full of exaggerations and additions in order to make it more like her own episodes with her mother. After I finished, Cathy cuddled up to me and made me promise never to tell another soul what she was about to tell me, and of course I agreed because I knew what was coming. And then she told me, and afterwards I was so fucking horny that we immediately, drunkenly fucked right there on the couch, adding a few fresh fuck stains to our poor abused couch cushions. Cathy added a few details that Joanne had left out, such as loving it when Joanne ate out or fingered her ass in addition to her cunt, or playing with her mom's pussy while they drove on long trips in the car, or being allowed to watch while Joanne fucked a few of her boyfriends. I suspected there was even more (did Cathy actually participate with the boyfriends instead of just watching?) but I didn't press the issue.
I tried to diplomatically suggest that she put a move on her dear old Mom just to see what would happen, but Cathy enthusiastically rejected that idea. She thought that Joanne was ashamed and embarrassed by their past, and I couldn't tell her that she was wrong.
So the next time I was at Joanne's house I told her all about it. Joanne resolved to put the moves on Cathy and invited her daughter on a week-long cruise through the Bahamas. And when Cathy got back, she had a new secret to tell me.
Now I'm waiting for a good time to suggest an openly incestuous three-way. And I haven't even thought about what might happen once Cathy and I decide to have a child or two.

THE END.
