After my time with Kim, I went back to work still smelling her cum on my clothes. Fortunately, it was a slow afternoon, and I didn't have to deal with too many customers in person. Walking in the door at home, Susan seemed very eager to hear about our 'lunch.' As I gave her the details, she moved me and the machine toward our bedroom.

Once she had me there, Susan closed and locked the door. Then, removing her clothes like a spastic stripper, Susan placed herself in the same position on the bed that I'd described in talking about Kim.

"Are you trying to tell me that you want the same treatment?"

"Yes! I want you to strap me down and let the machine fuck me for a while. Then I want you to flip me over and fuck my ass while the machine continues to take my cunt."

"Do my tales of fucking your daughter get you all riled up, Baby?"

"So fucking much, and I didn't get a chance to fuck Tom, like you did her, so you owe me."

Opening the case, I removed the straps to tie her down face-up. With that done, I set up the machine and grabbed a dildo while heading for the bathroom.

"Where are you going with that?" Susan inquired.

"I'm going to clean it off," I replied.

"No, you're not. I want that cum-coated cock used on me just as it is. I want that slut's juices inside me."

I strolled back to the machine as my mind whirled at this new side of my sexy wife. She seemed part jealous and part slutty whore at the same time. I was intrigued as I attached the used phallus and moved the machine in place. Looking at her pussy closely, I realized that there'd be no need for artificial lube since she was already leaking profusely. But, being so close, I couldn't resist a little taste. Flicking her nub with my stiffened tongue had her moaning and cursing.

"Oh, fuck yes! Lick my juicy pussy and make me cum all over your face as Kim did."

"Kim didn't get this treatment. This is a little bonus just for you, Baby." I continued to flick her clit until she shoved it hard into my face and came into my mouth.

"That's it. Lick my pussy and taste my juices like you did hers."

As Susan twitched from her climax, I moved my face away and moved to the machine. I turned it on with the fake cock at her entrance and let it take her. Then, between vocal moans, Susan ordered, "Fuck my mouth with that dirty cock of yours, you cheating bastard!"

Susan was really getting into this, so I decided to explore this roleplaying fantasy as far as she would allow. Releasing my cock while still fully dressed, I moved to her mouth and began slapping her face with my growing pecker. Every time she tried to take it in her mouth, I'd pull it away and slap her some more.

"Fuck! Give me that dirty cock, you fucker! Are you denying me because I let my son-in-law fuck me in every hole? Is my mouth not good enough...uuuggghhh?"

Before she could finish her statement, I stuffed my cock in her gullet and started fucking it fast. Susan was no stranger to deep-throating and took it like a pro. I'd set the remote for the machine within reach and grabbed it while stuffing her throat with my zealous prick. Turning up, the speed was pushing her over the edge faster. Still, I really wanted to change dildos to something much more significant.

Pulling my unsatisfied cock from her mouth, I moved back to change the dildo. She'd had the stand six-inch one, but I think it was time for the ten-inch monster. Susan had taken it before and loved every glorious inch, but it had been a while. With her new slut-like attitude, I thought it was time to see just how much of one she was. Susan couldn't see which one I'd changed it to, but she could feel it as it began stretching her restless puss.

I started it off slowly and only reached about a six-inch depth. That first plunge in brought out the animal in her immediately.

"Oh, you fucking fuck! Are you trying to tear me in two? But it feels so fucking good. So give me more, you cunt destroyer!"

I changed the depth first, gradually increasing it until she was taking all ten inches. Susan uttered no more intelligible words going forward. It was all a series of grunts and moans as her legs strained at the straps. Finally, moving back around the bed to her head, Susan opened her mouth. She waggled her tongue as more guttural sounds escaped her. Pushing my prick back into her throat, I pumped her to the rhythm of the machine.

Susan's climax hit her hard, and her ass came off the bed a few inches while every vein in her sublime figure became exposed. She blared around my intruding hard-on as I continued fucking her jowls. Suddenly Susan went completely limp, and I pulled out to make sure she could breathe. She sucked air hard as her chest expanded through her panting. I stopped the machine and unstrapped her hands before moving to her feet. As I began to move the machine backward, Susan closed her legs and begged, "Leave it there, please."

After another minute of catching her breath, Susan haltingly rolled onto her stomach. Once there, she pulled her legs up under her, leaving most of the beast still inside her pulsing and drooling puss.

"Fuck my ass... just like you... fucked hers, you fuck!"

Susan was still playing the game, so I grabbed the lube and prepped her for a good butt-fucking. Backing the machine up a little, I pulled Susan back to the edge of the bed where I could really give her a hard drilling. Then, turning the machine back on at a creeping pace, I pushed into her rectum without ceremony. She growled raucously before biting a mouthful of the comforter.

I was already so close between the two oral excavations and all her dirty talk that I just ramped up to a good pounding. I lasted about a minute before exploding in her ass and then collapsing onto her back. Susan's orgasm came close behind mine as the oversized phallus continued to plow into the depths of her vagina. Finally relenting, Susan pleaded, "Turn it off. I can't... just off."

I shut it off but didn't move off of her. Instead, as she lay there quivering, I kissed and nibbled her neck and back. "Are you done playing the jealous slut, my dear?"

"Yes, for now, but I may have to bring that back again later. Those were some incredible orgasms that you gave me. Especially with that tree trunk of a dildo that you managed to stuff inside my harlot pussy. So, what are the plans for the lake? I know that you have something rattling around in that perverted mind of yours."

"Well, it seems that your daughter has a fantasy involving being tied up and used by multiple men. So I thought that we'd give that to her in a way."

"In what way were you thinking?"

"I thought about a tree in the woods and blindfolding her. Then the three of us could take turns fucking her on and off throughout the afternoon. But that's so cliche. Then it hit me. I could tie her face-down in our rowboat blindfolded and set her up to be used at both ends. Kim would have no idea where we were in the lake. I'd stay in the shallows near our dock and pretend to hitch up to other boats. The other 'guys' would come on board and use her as well. She'd have no idea who it was, other than me. You could use an assortment of strap-on dildos in various sizes while Tom and I take turns in her two holes randomly. We could even get recordings from some of my friends talking about how sweet she looks all strapped down and ask if they could take her too."

"Do you think that will break her?"

"I don't know. Would it break you if you thought it was real?"

"Well, since we've done a couple of threesomes, I think it should. But, what if she wants more?"

"Then we'll jump off that bridge when we get there. Now speaking of wanting more, let's get that tree trunk out of you so that I can get my face in there again."

"Strip, you sexy bastard, I want to touch and suck you all over."

"Yes, Ma'am!" I replied after standing and removing my clothes.

After easing the dildo from her, we moved into a sixty-nine and brought each other to another slow-building climax. In the aftermath, we held each other tight and reviewed other thoughts about how to handle Kim.

"Do you think that we should tell Tom upfront and get some input from him?" I inquired.

"If we do and he doesn't want to do it at all, do you have a backup plan?"

"Well, I guess we could go back to the tree in the woods idea."

"Alright, let's do it. I'll call Tom, and we'll discuss it over 'lunch' tomorrow," Susan suggested before kissing me passionately.

"So, am I going to get what Tom does tomorrow night, you sexy slut?"

"You know it!"
