But quickly, it had become obvious to you that your pleasure came from your submission. Not just to me, but to her as well. You couldn't help compare her to yourself. She was younger, fitter, with perkier tits and a toned ass. You couldn't help but notice how much more turned on I got when she was with us, than when it was just you and me alone. You couldn't help but reduce your own role - preferring to sit back and touch yourself as you watched us fuck. Getting her wet then guiding my cock into her, your eyes looking up at me, pleading me to fuck her pussy. Licking her clit as I moved in and out of her, ignoring your own throbbing pussy in favour of pleasing her. Marvelling the way her body responded to me - watching my cock thrust in and out of her as she let out guttural moans of ecstasy. Getting wet as you fingered yourself to the sight of my arm gripping her hair and pulling her head back as I rammed into her from behind, beads of sweat rolling down our bodies as they slapped together. My balls swinging and hitting her clit with every thrust, her arched back emphasizing her ass as she pushed back on me, egging me on, telling me to slap it, telling me to cum inside her.
The first time I emptied my load into her, you'd cum instantly. It seemed so dirty somehow - your man was marking another woman with his seed. That should have belonged to you, yet she took it. She took it while right in front of you, looking at you with a smile on her face as I groaned, my cock buried in her, pulsing and shooting inside her. Jealousy, anger, shame - all these emotions went through your head as you moved your fingers faster and faster, in and out of your pussy, pinching your nipples as your orgasm overtook you. Shuddering, tears streaming from your eyes as you humped your own hand in front of the woman who had taken me away from you.
That was the point of no return. She knew you would do anything after that. No matter how degrading or humiliating. And she was right. You did not object when she had laid back and gestured at you to crawl to her. You had silently knelt between her legs and kissed her pussy, tasting her wetness. Tasting her superiority. You had let out a moan as you felt her hand at the back of your head, pushing your face deeper into her smooth, freshly fucked pussy. Knowing that I was watching, you'd licked her clean. Lapping at her clit, making her squeeze out my thick, hot cum so you could taste me in her. Feeling her pleasure mount again as her moans became more insistent, flicking your tongue faster and faster.
You didn't know why you were trying so hard to please her. She had just fucked your man while you had watched, she had just made me cum in her while you had humped your own fingers, desperate and deprived. You should have been furious. You should have asked her to leave. You didn't know why you didn't. All you knew was that your pussy was dripping wet with lust. You wanted to prove yourself - to whom though? To me? Or to her? It didn't matter. Perhaps if you could make her cum, I would see that you are good for something again. Perhaps she would let you participate more if she saw you could make her happy. Perhaps I would fuck you next if I saw how desperate you were from my cum, willingly licking it from another woman's pussy. It didn't matter. Your tongue moved faster and faster, circling her clit, tasting the cum oozing out of her tight pussy as she came again, rubbing it up and down over your face, smearing you with the combination of our juices.
That was the first time. It was not the last.
Every little step after that drove your humiliation further. You knew you could stop it at any time. You knew I would put an end to it the moment you told me you were uncomfortable with it. But you didn't. You had thought about it. You had thought about it when I told you to thank her for fucking me better than you ever could. You had thought about it the time I had pulled out of her ass and made you lick my cock clean. You had thought about it when she had squatted over your face and pushed the cum out of her gaping asshole into your eager, slutty mouth. You had thought about it when she had told you to lie down on your stomach so we could fuck on top of you, ignorining you completely. You had thought about it when I told you to get a spare key made for our apartment and present it to her on your knees so she could come and go when she wanted. You had thought about it when you had watched us get ready to go out on our first date without you, knowing that she wasn't wearing anything under the beautiful dress you had picked out for her. Knowing that my hands would be inside her on the dance floor as she grinded her ass over my cock. But you hadn't done it. Because with each action, your pussy had gotten wetter. Each step had taken you deeper into your humiliation, until all you could do was crave more. It had stopped becoming about your pleasure - now all you wanted to do was prove your worth to us, hoping that if you made us happy, you could somehow satisfy the needy urges in yourself.
You'd spent the whole day being the perfect domestic pet. Cleaning the apartment, cooking for both of us, changing the sheets on the bed. Simple tasks, but your thoughts while doing them made them almost impossible to do. Try as you might, you could not deny that it wasn't just me that you were doing them for. You had cooked food that you had hoped she would like too. The wine you had gotten was her favourite. The sheets were changed because you didn't want us to be distracted by your scent as we fucked on the bed that you should have shared just with me.
She'd arrived an hour before I reached home. You'd greeted her how she liked - eyes downcast, your pussy getting wet as she handed you her bag without looking at you. Her bath was ready - the temperature just how she liked. You'd helped picked out the lingerie she would be wearing, laying them out ready for her on the freshly made bed. You'd waited patiently until she was done getting ready and walked out to the living room, where you were sitting on the floor, next to the couch.
