As for Steve, I think I have a plan for him. Please pass me the plug you had been wearing today.
Gwyn took the plug and placed it in front of Steve. "Clean this", she commanded, and she put the plug in front of Steve's waiting mouth. "Hold this in your mouth until I return." Steve opened his mouth wide to fit the ball plug, and wrapped his lips around the base to hold it in place. "Amy, I assume you have a collection of toys in your bedside table that you have collected and used to satisfy yourself when Steve just wasn't enough. Is there a vibrating buttplug in there that is big enough to stretch Steve nicely, preferably one with a remote control?"
Amy nodded her confirmation, and Gwyn left Steve with the plug in his mouth and went off to find Amy's toy collection.
Amy turned to me as I continued to sit on the stairs, streaming all of the action and conversation to Diana.
Amy walked to me and kissed me briefly on my bright red lips before speaking to me finally. "I know that you fucked my ass two weeks ago. You'll probably didn't realize at the time how much I loved being used that way by you. I needed to have my ass fucked and I really needed to give myself over to submission wholeheartedly. I would have done anything for Diana in that moment, and to be simply taken and used by you was enormously liberating. It let me know that I needed to submit, and that I was capable of going deep into the process. The fact that I kept licking Diana's lovely pussy while you were fucking me, and that I didn't feel degraded, but actually felt a sense of relief and release, was astounding to me. It was so good that I almost forgot that Steve was having his asshole reamed out the whole time we were involved.
The thing is, since that moment I've actually fantasized about finding out who you were and repaying the favour to you. I wanted to strap on a rubber cock and fill you up, maybe even making you cum just from having your ass fucked. If I'd known who you were, I might not have been able to develop that fantasy, but seeing you here, dressed like a woman and at my disposal, and having explicit permission to use you how I like, makes me the whole fantasy I've developed come alive. I am going to fuck you, in front of my sister, and once I'm done and you are both used and pleased, I'm going to sit on your face and ride to you a series of orgasms like Steve has never been able to bring me to. I've heard how good you are with your mouth, and I'm going to give you a chance to prove it.
Gwyn brought me a gift in that box, and I assume that it is mine to keep. I presume she thought that Steve would be the first to ride that fake cock, but I'm going to change that game and give you first crack at it. Now -- put the phone down in a place where Diana can see everything that is happening, and go get me my new cock. You can help me put it on, and then I'll help you out of your clothes. I'm looking forward to seeing your lipstick covered lips wrapped around my new toy."
I stood up and placed the phone in the best place I could think, sitting against a stair with a wide view of the room, and I picked up the box with the new strapon and harness and took them out. I knelt on the floor in front of Amy and worked the harness up her legs and into position. I was so close to her wet pussy that I leaned forward and gave her a lick, which resulted in a quick slap across the face -- nothing too hard, but enough to get my attention.
"You will get a chance to show me your skills later, but for now I want you to just do what you are told. Now -- put that strap on into place in the harness, and show me how you suck a dick." Amy ordered me.
I put the hot pink strapon into the harness, and finished sliding the harness up into place. I took a brief moment to push the harness plugs into Amy's waiting pussy and ass, tightened all the straps so she could have complete control of her new toy, and then I proceeded to take the rubber cock in my mouth. As I took the dildo deeper into my throat, I intentionally pressed my lipstick covered lips against it so I could see how far I was able to take it. I guessed as I pulled her in and out of my mouth, that I was at least 6 inches down on the dildo and I was getting closer and closer to gagging.
Amy stopped the show, and took me by the chin to lift me up. She looked me in the eye and moved me into the living room and pushed me over the back of the couch. As I bent over, she smacked my ass and made me jump, before reaching around me to grab my nipple chain and pull it up and out of my dress. She tugged on the chain, making me gasp in both pleasure and a little pain, and the she continued to rub me all over in the front and back as I was bent over and exposed to her.
When she was ready, she lifted the back of my dress and exposed my panty covered ass. She pulled down my lace panties, and roughly and excitedly pulled the plug from my ass and threw it onto the couch. She leaned over me, forcing the rubber cock between my legs, and slowly worked herself into position so that the head of the cock was waiting to impale me. I was still completely lubed up and prepped by having the plug inside me, so it didn't take much effort for her to slide the head of the large toy in. From that point, Amy took her time working her newfound penis deeper and deeper into me. I moaned with each thrust of her cock, and sighed as she pulled back a little. I could tell from how she was progressing that she was incredibly excited and only holding back a little in order to make things last just that extra moment longer.
"Go ahead and moan", she said. "Make all the noise you want and let me know what you are feeling. Let me know how much you want to be fucked by me. I love that you are my bitch today, and that I can use you any way I like. I have Gwyn's permission to make you do anything, and to fuck you and use you however I please. Right now, I just want to feel you weak in the knees under my power, and know that the deeper and harder I put my cock inside you, the more you feel the need to be used by me for my own pleasure."
Amy stopped talking and started riding me harder and harder. I knew that I could take the pounding, as Gwyn and I had experimented beyond this point, but there was no doubt that Amy was stretching me, and pushing me, and feeling the little bit of dominance that was hiding under her usual submissive shell. As she worked herself into a rhythm, and evenly ran her fake cock in and out of me, I could hear moaning from the hallway and I wondered what was happening there. I tried to listen and understand what was happening, but I stopped listening all of a sudden as Amy pushed her entire toy into me and fell over on top of me. She collapsed from the effort and the excitement, and came to a complete stop while she was lodged deep inside me. I couldn't move for fear of her falling, so I just waited quietly and made myself completely still until Amy caught her breath and stood up, pulling herself out of me completely. I sighed with delight as the sudden removal of Amy's strapon left me gaping and gasping for air.
In the sudden silence, I could hear my wife's commanding voice ordering and instructing Steve in various tasks.
"Lick my asshole!" "Put your tongue in deeper." "Stick that tongue out and fuck me with it!" There were a long series of commands coming from that hallway, and at some point Steve must have started to figure things out as I heard Gwyn moaning. "That's right Steve, that's the way to tongue fuck my asshole." I could tell that Amy was listening in on the action in the hallway as well, and eventually Amy stood up and took my hand to lead me back towards Gwyn and Steve.
We found Steve lying on his back on the hall carpet, with Gwyn sitting on his face and moving herself around to control the focus of Steve's actions. Amy knelt next to her sister, kissed her lightly on the cheek, and whispered something in her ear. Gwyn looked at Amy and nodded, at which point Gwyn opened the box with the new strapon and replaced the used toy at her waist with the new clean one. Once Amy was ready, Gwyn lifted Steve's legs up exposing his ass and the base of what was obviously a large butt plug was sticking out of him. Amy gently pulled the plug, which was vibrating the whole time, out of Steve's ass, and quickly knelt between his legs and entered him with the new red dildo. As she took control, Gwyn removed her asshole from Steve's willing tongue and moved away from both of them and took my hand leading me to the stairs.
We sat together and watched the scene as Amy took charge of her marriage. I hoped that this was a real turning point, and not just a one time event. Amy fucked and fucked Steve, stretching him wider and wider. Steve squeaked occasionally, but mostly just moaned erotically under the dominant spell of his lovely wife.
Gwyn and I kissed occasionally, but mostly just watched in amazement as Amy became the commanding one before our very eyes. Gwyn whispered in my ears, "Now that they seem to have figured out a few things, I'd still like for you to make me cum. I was most of the way there before Amy took over with Steve, but your tongue on my clit will finish me off in seconds I'm sure."
