I shut my computer off, but my mind was abuzz with images and ideas, and thoughts. Very naughty thoughts a mother shouldn't have about her children. I looked down and realized the computer desk, and everything on it, and under it and even the wall was dripping wet with the cum I had sprayed everywhere. After having one of the most violent orgasms in a long time.

I quickly cleaned up my mess before Jack came in for lunch. He had been out working in the garden all morning and would be in soon for a break. It might be the best time to tell him about what I had seen taking place on the zoom call with our daughter.

I struggled with my vivid thoughts for at least thirty minutes before I decided to put off telling Jack until the lockdown was over, and we could see our kids again see how I felt then. I love Jack with all my heart, and we don't keep secrets from each other. We also live a somewhat open relationship and have both taken lovers while on business trips. We also have a regular couple of close friends that we swing with from time to time.

But to tell Jack I was having lustrous thoughts of sex with our kids. I'm not sure how he would react to that.
I had just finished making Jack some sandwiches and a jug of lemonade when he came in, all hot and dirty covered in sweat.

"Wow, the sun sure does have some bite in it today, but I got all those lawns mowed and the hedges trimmed. I think it's going to be a hot summer if we ever get out of lockdown. By the way, did you call out to me earlier? I thought I heard you but wasn't sure over the noise of the lawnmower. I should update it with one of those self-propelled four-stroke ones. They are much quieter."

"No, I didn't call you. I agree it would be nice to get away. I could do with a week at the beach working on my tan. My body is lily-white at the moment I look terribly pastie."

I poured Jack a glass of lemonade, and he gulped it down before sitting down at the breakfast bar.

"Did you talk to the kids? How are they coping? I know you were worried about their mental well-being locked up together. Their apartment isn't really big enough to get away from each other."

I could feel my face beginning to blush as I searched my mind trying to come up with an answer to Jack. Still, all I kept picturing was Tom holding Sarah's head against the kitchen bench and fucking her so hard and violently. Using his sister like a common whore just how I like being fucked by him.

"Oooh fuck, ooooh God."

My legs buckled, and I had to hold the bench to stop from falling. Holy fuck, I just had another mini orgasm picturing the scene in my head again.

"Honey, are you ok? What's wrong," Jack said, alarmed, jumping up and holding me.

"I'm sorry, I'm fine, darling, just a bad stomach cramp that's all it has passed. I'll be fine," I said to Jack, but my clean panties were now soaking wet again. 

"As long as you are ok? You made the same face you make when you cum," he said, having a little chuckle.

"Haha, very funny."

Jesus, I couldn't stop thinking about what I had seen. I ran it over and over in my head. How did Sarah know Tom's cock was bigger than Jack's? Another question I kept wondering about.

Sitting down next to Jack, I said, "The kids are fine. In fact, I think they are more than fine. I would say they are very happy. Jack, to your knowledge, has Sarah ever seen you naked? I mean in the last few years."

"What sort of question is that? And how would I even know if she had? Why did Sarah say something to you today?"

"No, not at all. I was just curious. Sarah has seen me naked plenty of times. I was just wondering if she had seen you naked?"

"I don't really know. I don't think so, not that I recall anyway. That's a pretty specific question to ask me. I'm guessing you are going somewhere with this."

Damn it. I thought I couldn't keep what I saw from Jack. I needed to tell him. No, I needed to show him. He needed to see what's going on with his own eyes to understand.

"Are you finished outside in the garden, darling?"

"Yeah, pretty much it's getting too warm to do any more today. I think after lunch, I will take a shower and relax with a drink. Maybe we could watch a movie or something."

"Hmmm, I think I have the perfect movie to watch," I said.

We finished lunch, and Jack took a shower; while he was in the shower, I transferred the recorded file I took of the zoom meeting and put it on a memory stick. Then I put it in the USB drive of our TV and waited for Jack.

Jack grabbed a couple of cold beers out of the fridge and flopped down on the couch next to me.

"I hope this isn't one of those romance girly movies. What is it?" He asked.

"No, it's not a romance, but it does include nudity and quite a vivid sex scene or two."

"Great, I'm starting to like the sound of it already," Jack said as he placed his large hand high on my bare thigh under my summer dress. It sent a shiver down my spine. I love the way my husband makes me feel when he touches me.

I scanned through the TV channels and found USB 1 input, and clicked play. The screen burst to life as Sarah was kissing her brother Tom and jerking off his fat cock.

I looked a Jack, and he had the same expression I'm sure I had when I saw it as well.

"Sue! What the fuck is this? Is this what I think it is?"

I hit stop and looked at Jack. I knew he was going through all the emotions I had gone through. When the realization set in that our kids were sexually involved with each other.

"Sue, where did you get this from?"

"I recorded it this morning during my zoom meeting with Sarah."

"What? Our kids fucked in front of you during your call with them?"

"No, Sarah forgot to turn off her camera and log out of the meeting after she said goodbye to me. I only started screen recording when I remembered that I had an app that allowed me to record what's on the screen. There is a lot more to watch, should I continue? It's not even at the best part yet. Do you want to watch it?"

"No! I don't want to watch my kids fucking. Jesus Christ, and what do you mean the best part. Wait, did you masturbate while watching our kids fucking?"

Tom stood up and paced around the living room, shaking his head.

"This is our fault. Somehow the kids got the idea that it's ok to explore their sexuality with each other from us. I knew I should never have told Tom about our open marriage arrangement; he has taken it literally to explore all things sexual," he said, sitting back down.

"Jack, don't be ridiculous. It has nothing to do with us, and you know it. Have you ever thought they might just love each other?"

"Sue, it sounds like you are ok with this. Are you ok with our kids fucking each other? You know it's wrong on so many levels."

I knew exactly how I felt about it. The fact my panties were wringing wet just thinking about them together. And Tom fucking me stupid and then having Sarah eating his thick cum out of my pussy was all I needed to know.

"Yes, Jack. I'm starting to be ok with it. I don't know why but if you watch the rest of the recording, you might feel the same way I do."

Jack looked at me. He drained the bottle of beer he was holding, grabbing mine; he did the same to it and said, "Ok, push play, let me see what it is that makes you think this is ok."

The image of Jack's baby girl Sarah jerking off Tom came back on and progressed forward. Jack put his hand back on my thigh as we watched, and I could feel his palm getting sweater every second. His body was twitching, and he shifted uncomfortably in his seat.

Around five minutes in, when Tom was running his cock up and down through Sarah's pink pussy lips, I looked at Jack's crotch, and I knew he was enjoying what he was watching as his son was about to destroy his baby girl's tight little hole.

I put my hand on Jack's rock-hard cock through his shorts. Leaning over, I said, "See, I told you so. How amazing does Tom's thick cock look spreading our baby's very pretty pussy open?" I said, giving Jack's cock a firm squeeze.

"I had no idea I was going to feel this way. I'm ashamed and mortified that I'm even watching it. But there is no denying how incredibly turned on I am right now." Jack said as he undid his shorts and pulled them off.

I didn't need any more encouragement and quickly discarded my soaked panties and swung my leg over Jack's lap, and lowered myself onto his glorious cock reverse cowgirl so I could watch the screen as well. I think I had only pumped up and down several times when Sarah screamed out on the screen, "Oh daddy, I want you to fuck me, I want you to make me your filthy bitch. Fuck me; daddy fuck my slutty cunt."

Jack grabbed my hips and forced me down hard on his cock; his body tensed up, and he coated the insides of my cunt with copious amounts of his thick creamy spunk. The feeling of Jack's cum, blasting against my uterus sent me over the edge, and a torrent of my sweet girly juices coated Jack's big balls and the sofa.

After catching our breath, Jack looked at me and said, "I think we have just crossed some socially acceptable line. Parents aren't meant to feel like this about their children."

I looked back at the screen, and it was at the part where Tom Asked Sarah, "You want to fuck dad, don't you? You dirty little slut."

Tom picked her up in his arms and sitting her on the kitchen bench. "Yes, I do. But no more than you want to plough mum's cunt with your huge cock."

I paused the movie. I got up, turned around, and sat back down on Jack's lap. "You might be right, Jack. We may have crossed some moral line. But I guess most God-fearing folks think we do that every time we fuck someone outside our marriage, so I'm comfortable being on the wrong side of that sort of moral high ground, aren't you?"

"You have never once indicated to me that you wanted to fuck our daughter, and here is your little girl saying she wants to fuck her daddy. And Tom wants to fuck me. Despite how we feel. It's clear as mud our children think differently and want to share their bodies with us."

I was sliding my dripping wet pussy back and forth on Jack's still hard cock. I knew he was ultra turned on as his cock hadn't deflated since he came in me.

"I'm going to be completely honest with you, darling. You know I love you more than anything else. But love me or hate me for what I'm about to say. But I want Tom's thick long cock buried to his balls inside me. I want him to fuck me till I can't walk properly. And then I'm going to squat over our baby girls mouth and let her suck all of Tom's thick creamy cum out of me while you fuck her."

I felt Jack's cock twitch when I confessed that to him, and I'm sure he wanted to fuck our kids now as much as the kids wanted to fuck us. I lifted back up, grabbed his rigid cock, sank back down on it, and began riding his thick throbbing cock. I rode him like I was possessed, and maybe I was. Because all I could think about was, it was Tom's cock stretching me open right now.

Then out of the blue, Jack said something that changed my world. Taking hold of my nipples, he squeezed and twisted them painfully hard, but then he knows that's what I like. It's the pain that comes from rough nipple play that always heightens my orgasms. 

"Do you like my big cock, mommy? My big cock feels so good in your tight little cunt, doesn't it, mommy? I have wanted to fuck you for so long, and now I get to turn you into my mommy slut. Tell me how much you love fucking my big cock? Does it feel bigger and better than dad's cock? I bet I fuck you much better than he does, don't I?" Jack said, ad-libbing some role play.

"Ooooh fuck, yes, Tom. Fuck your mommy; ooooh God, your cock is sooo big I fucking love it. Fuck your mommy's tight cunt, baby; oooh fucking yes."

Leaning back, my cunt exploded flooding Jack and the sofa again. The pressure of my cum squirting off of Jack's chest and spraying back all over me. I twitched and flopped around on Jack's cock until everything went black. There have been a handful of times I have blacked out from overwhelmingly powerful orgasms. Jack's role-playing of being Tom just sent me completely over the edge. I fucking loved it.

Jack laid me on the sofa before climbing between my legs and licking the abundant amount of juices flowing out of my pussy.
Slowly I opened my eyes with the beautiful sensation of being eaten out. Without even looking down between my legs, I closed my eyes and ran the image of Sarah looking into the camera. Telling me Tom is going to fuck me and she would eat my pussy clean. God, I instantly felt another orgasm surging through me. Her tongue fucking my cunt felt so good.

"I'm such a nasty mommy having my little girl eat her mommy's pussy. Oh fuck, yeah, Sarah, your tongue feels so good in my hot wet cunt. Suck my clit, bite it, baby girl, oh fuck yeah, I'm going to cum, oooohhh fuuuuuuuck yeeeeessss.

Jack crawled out from between my legs after I unclamped them from around his head. His face a slimy mess with my sweet cunt juices. His cock still hard, he knelt on the sofa and fed his thick tool into my mouth. I willingly sucked on it, taking it down my throat as he pushed it in further and deeper.

Wrapping my hand around the base, I jerked him and sucked him until his balls shrunk up into their sack, and he unloaded a massive load of spunk down my throat. I hungrily drank it down before licking my lips and smiling up at him. I propped myself up, and Jack sat down, and I laid my head back in his lap. Jack was the first to speak.

"I guess there is no going back now the genie is out of the bottle, so to speak."

"No, I guess not. I can't very well deny my feelings now. There is only one way forward. We have to fuck our kids when they lift the COVID restriction. My pussy just hopes it's sooner than later because I want Tom's cock buried inside me while I eat out Sarah's gorgeous pussy."

Jack stroked my hair, and for the first time since I had shown him the movie clip, he admitted he was on board even though we had just role-played. Jack hadn't outrightly admitted he wanted it as much as I did, but then he said, "Do you think Sarah's pussy tastes as good as it looks? She has such good-looking pussy. I'm getting a little excited at the prospect of fucking my little girl now that we have decided that we are doing this."

"If she tastes as good as me, her pussy will taste beautiful," I said, teasing Jack.

"No one tastes as good as you, darling. I've never eaten a pussy I didn't like, but I've never eaten a pussy that's come close to yours."

I looked up into his eyes and said, "I fucking love you, Jack. Don't you ever forget that. You truly are the man of my dreams."

That was three weeks ago. It was now June 9th, the day after the COVID stay-at-home order was lifted. We were now allowed to go out, and better still, we were allowed to have the kids visit us.

In the following two weeks, until the COVID restrictions were lifted, there was not a single indication of anything having transpired between Tom and Sarah and, of course, Sarah's omission to me into the camera that she wants to eat my pussy.
Maybe she was just fantasizing that I had been watching. But that didn't change the fact we now knew our kids were fucking each other.

It was Tuesday. I zoom called Sarah and asked if they were coming to see Jack and me on the weekend. Sarah said they were planning to come home on Thursday and go back to the city on Monday morning. I was giddy with excitement at the idea of seeing them both. It had been a couple of months.

"You seem very excited about us coming home, Mum. Do you have something special planned? Or are you just excited to see us both?"

"Baby, me and dad are so happy you are both ok. We are simply thrilled to be seeing you both again. That's all."

"So are we, mum. I know Tom is extremely looking forward to seeing you, and I'm terribly excited to see daddy....
