Despite Leo’s outrage at Ana’s cheating, he was still beside himself with indecision. After all that he had been through in the past few weeks, he still did not know how to proceed without a catastrophic negative reaction from his wife for his own untrustworthy behavior.
Despite everything, he still wanted her. In fact, he wanted her more than ever. He just had to put a stop to this madness of Ana’s. However, there was still the stalemate issue of his finding out about her cheating by reading her diary. Everytime in the past few days, when he was ready to confront her, he backed down at the last minute.
Compounding his anxiety, whenever he tried to initiate sex with her in the past few days, she’d shut him down. She had not been in the mood for some time actually. That was not a good sign.
The biggest problem was that he still very much loved his beautiful wife. In fact, during the past few weeks, the idea of them moving forward together as a couple with some kind of an open marriage arrangement was beginning to appeal to him. However, the cheating behind his back had to stop.
On Friday, she went out and came home with a choker around her neck. Or at least it could have been a choker. It was made of braided gold, with a ring hanging from the middle and a buckle in the back rather than a clasp. Some might call it a collar.
It looked expensive, but when he asked about it, she said it was nothing and just a new fashion trend she was trying. He was not convinced the explanation was that simple.
When they went to bed that night, he noticed that she did not remove the collar. She did not take it off even to shower the next morning. It appeared to be a new permanent fixture in their lives.
One final thing had him extremely worried. Ana had stopped writing in her diary. After writing at least one entry a day for years and years, she hadn’t written anything for days now. It was not like her.
What that could mean left Leo wondering if she knew he was reading her diary. Or worse, that she was just too excited about her illicit behavior and had no time to write. She was certainly being even more guarded and secretive than ever.
While his mind was spinning through these thoughts, he came to learn something that brought everything to a full stop. Ana had quit her job. When he asked if she was going into the office the Monday morning following the four-day holiday weekend, she told him the news.
“What did you say?” he asked incredulously.
She seemed a bit surprised at his question, but said, “I won’t be going back.”
“What do you mean? You quit?”
“Yes. I’m going to ... look for something ... more fulfilling.”
“Christ, Ana. That’s going to impact our budget. How will we pay our bills? My God, we won’t even be able to afford the rent on our lease.”
“The lease?” she said with raised eyebrows as if she hadn’t considered that dilemma before. “I don’t think that will be a problem.”
“Not a problem? Don’t you think we should have discussed this?”
She stopped and gave him a long stare. He had trouble reading her eyes in the deafening silence. They seemed to turn from disinterested to confused to angry within seconds.
“Does it surprise you that I have decided to do as I please ... my husband ... the man I once trusted?” The venom in her words and the way she punctuated his marriage role, struck him full force and set him back on his heels. The fact that she said she had trusted him -- in the past tense -- alluded him for the moment.
“What?”
“What, indeed.”
“What are you talking about?” If this was what he thought it might be, playing innocent was the only option. If it was something else, he was quite sure he was innocent.
“Did you think I wouldn’t find out what you’ve done, Leo?”
“What I’ve done?”
“Don’t play stupid with me. You went to Anton. You told him that you read my diaries.”
It was if a black hole had collapsed in front of him. Realization hit the young husband with a nuclear force he had never experienced before. Confusion followed closely on the tail of its shockwave.
Anton. Sir was Anton, and that damn old man told Ana about their conversation. Leo had walked into a trap that day in their landlord’s office.
“Whaaa...”
“Yes. You read my diaries, and I’ve caught you. You snuck into my closet like a thief in the night and read them one after the other ... over months, possibly years. How could you? I trusted you!”
“Wait a minute!” he shot back in anger and confusion. “I’m not the only one who violated a trust here.” That seemed to be a poke at an angry cobra, because now she clenched her fists and looked like she was ready to strike.
“And no wonder? Why shouldn’t I find satisfaction with a real man when you can’t do the fucking job. You’re too busy sneaking around trying to find out my most intimate thoughts, you asshole.”
She pointed at his chest and shouted, “You’re not the man I thought you were.”
Another shockwave rolled past him. Hurt followed in its wake. The only noise he heard for some time was his wife’s angry breathing.
“OK, listen. Ana, honey. I made a mistake, and I ... I’m sorry, but I think of the two transgressions, cheating is worse. Don’t you?” It was all he could think of to save this. He was trying to be reasonable, but she wasn’t having it.
“Sure! Try to make me out to be the bad guy!” she stated, slipping her wedding ring off and placing it on the nightstand. “I’m done.”
She walked out the door, not just the bedroom door, but the apartment door, as well, slamming it as she went. That did not go well. He would not see his wife again for weeks.
Ana’s (New Digital) Diary Entry -- July 6
Leaving the apartment I ran into Mrs. B in the elevator. Just what I fucking needed. She gave me an angry side glance, but I wasn’t in the mood.
“We’re exactly the same, you know,” I said matter-of-factly, turning to her. “You can hate me if you want, but we could also be friends. It’s not like your husband means all that much to you. He certainly meant nothing to me. We’re just two women who were used by a man. What else is new?”
She said nothing for several minutes, but I could feel her distaste for me dissolving. Soon I went on. “We have a lot in common, I think. I would like to be your friend. And, I am sorry for what I did.”
She turned and looked at me. “You want to be my friend?” All anger was gone from her voice. She seemed ... what? ... intrigued? God, she has such a cool accent. It’s kind of funny to see a refined British voice come out of a brown lady.
“I definitely do.”
“You intimidate me. You’re all breathtaking blonde beauty ... a so fucking sexy.” Wow! Was she coming on to me? Best to ignore it for now.
“You’re very pretty, too. Remember that Sergei threw me over for you.”
“And then, he threw me over for someone else. I think he’s working his way down to the bottom.” We both laughed.
“I have to go now,” I said, “but we should get together and talk.” The doors opened, and I turned to leave.
“My name is Kanta, by the way.”
“I’m Ana,” I said as the doors closed.
Minutes later, I sat in the coffee shop absentmindedly touching my beautiful gift from Sir. It felt so good around my neck and made me smile.
It calmed me and made me feel desired and loved by a man worthy of my love and admiration. I kept remembering the utter joy of that monumental moment when he put it around my neck with great ceremony.
He said it was a special time for us, one that we would both remember all of our lives. It was the day he made a commitment to me, and I gave him my heart and soul.
I looked at my finger where my wedding ring once rested. It felt empty, and the indent in my skin the ring had left behind looked funny. I would have to get something appropriate to replace it. Maybe Sir would.
When he told me of Leo’s treachery, I could not believe it. It was easy to agree with my new owner that my husband did not respect me or deserve me.
After learning that news, I had a great feeling of ambivalence toward my husband. I didn’t love or hate him. I just stopped caring. Maybe I actually stopped caring a long time ago, and I had just chosen to ignore the fact. I’m not sure. I do know that whatever I once felt for Leo paled in comparison to what I was feeling now.
I also knew that I was going to put all my trust in Sir. I would put my future totally in his hands. I quit my job, because Sir said he would find something better for me. I was ready to leave everything up to him. As a good pet should.
Two young men at another table were staring at me and whispering to each other. I looked down and understood why. My nipples stood out from my sports bra as hard as bullets, and goosebumps covered my bare legs as I sat and thought about Sir.
Just the idea of Sir at any random moment would cause sexual lightning to strike me. All I could think about was his delicious mouth doing wicked things to me, or that magnificent cock reshaping my tight little pussy.
I sat there thinking that every aspect of him fascinated me. How big a difference a week had made in my mind? I had only recently looked at him with suspicion and anger, but now had been completely tamed.
We talked so much in the past few days about everything under the sun. I liked him. He was someone I could admire, someone who had come to this country and made something important of himself.
He was so smart, and he cared about the things I cared about. We matched in so many ways. We even talked about what it would be like to have children.
As I sat there, I realized that I missed his smell. What experts call pheromones, I now thought of as a distinctly Russian male smell -- sweat and virility. My grandfather had it, too. Leo, by contrast, just smelled like plain old deodorant soap.
I thought about Sir’s body. He wasn’t pretty, not even handsome in a conventional way. He wasn’t young or thin or ripped. He was just male. So very male.
When I stormed out of the apartment, I was dressed for a run, but I had no desire to run anywhere but to my new man. That’s when I sent him a little text.
Me: I walked out on Leo, and I need your guiding hand right now, holding me down, making me do nasty things.
Sir: Tell me more.
Me: My pussy tingles at the memory of how you stretched it. It weeps for you.
Sir: Yeah?
Me; I get all creamy at the thought of your towering cock looming over me.
Sir: What would you do if I was there right now?
Me: I would beg to worship my master’s glorious cock.
Sir: And if I granted you permission?
Me: I would take you into my mouth like a dirty little slut. I would gag on your perfect cock to show you how much I needed it.
Sir: Then what?
Me: I would bend over a table in this coffee shop and beg to be fucked. My body is screaming for you!
He asked me where I was, and I sent him my direction. He told me not to move as he was on his way. I liked that I actually got him to come to me. Power shifted just a bit.
He was there in 20 minutes looking fine in a dark suit and scarlet tie. The look he gave my two young admirers made them wilt like unwatered tulips on a hot day. I may not have given jealousy its due in the past, but it certainly looked good on him.
I looked up at him and smiled brightly. He looked back at me with torrid desire as if he could take me right on that spot. A warm, creamy sensation shot from my belly to my pussy.
“Come with me,” he whispered sharply. I followed him past the counter, around the corner and into the bathroom. Thankfully, it was a one seater.
He locked the door and turned to me with a half-crazed look in his eyes. I couldn’t take my eyes off of his. My heart raced and my stomach flipped as I stared into that smoldering look. I could get used to this kind of intense desire. It was intoxicating.
“What do you have in mind?” I asked quietly. “I hope it’s something naughty and fun.”
He said nothing as he closed the distance between us, forcing me up against the sink counter. His big body pressed into my curvy one without breaking that intense eye contact. The smell of his cologne invaded my senses.
“Sir, you’re so naughty, bringing me back here like this. What if someone comes and sees us?” I purred tracing a finger down his chest.
Placing his hands on the counter to trap me unnecessarily in one place, he brought his mouth down to my ear and whispered, “Don’t you worry, little girl. Someone is definitely gonna cum in here.”
He kissed the side of my face and his lips traveled down my jaw until they covered mine, and I couldn’t control a moan from bubbling up from deep in my chest. “Mmmmmmmm, baaaaabbbby.”
I yelped in surprise as Sir spun me around and bent me over the sink with a hand on my back. I looked back at him over my shoulder, eyes filled with lust and anticipation.
“Oh, baby, you’re so forceful! I love it,” I purred, wiggling my ass enticingly.
“Good, then you’re gonna love this,” he said, as he yanked my tight little shorts and panties down to my knees.
I let out another soft moan as he exposed my smooth, round ass. I gazed at him with half-lidded eyes, biting my lower lip.
“Mmm, yes, I want you to give it to me hard,” I whispered, arching my back to push my ass out further. His hand come down hard -- SLAP, SLAP -- and the pain registered on the nerve endings in my ass cheeks.
I yelped in surprise and pleasure as Sir’s rough hand came down hard again -- SLAP, SLAP -- leaving bright red handprints. I snapped my head forward to look at him now through the mirror, my eyes sparkling with desire.
“Oh, Sir, you’re not playing around today, are you?” I moaned, wiggling my ass again. “I like it rough, so you don’t have to hold back with me.”
SLAP. SLAP. SLAP. SLAP. He gave both of my young firm ass cheeks more good sharp smacks with his hard old hand.
“Who owns this ass, Ana?” He asked, now rubbing his hand over the warm, reddened flesh.
“You do, Sir. You own my ass. You own all of me,” I moaned, pushing my hips back against his hand. “I’m your little slut, to use any way you choose.”
He lifted his foot and used it to push my shorts and panties down to the floor, so I could step out of them. Next, he pushed his knee between my legs to force them wider apart.
I whimpered as Sir easily positioned my body for his use, feeling exposed and vulnerable in the best way possible. I looked at him through the mirror, my blue eyes filled with need and desire for him.
“Please, baby, I need you inside me,” I begged, wiggling my hips enticingly. “I want to feel your big cock stretching me out and filling me up.”
He slapped my ass again, and said, “When I’m damn good and ready, bitch!”
I let out a yelp as Sir slapped my ass one more time, feeling the sting spread across my sensitive skin. We made eye contact again through the mirror, and he saw my pouty expression, my lower lip trembling slightly.
“Yes, Sir,” I whimpered, trying to be patient and obedient despite the overwhelming need coursing through me. “I’ll do as I’m told.”
I felt one hand cup my pussy from behind. “Is this cunt all hot and ready for me?”
I moaned softly as Sir’s rough palm pressed against my sensitive pink folds. I gave him a sultry look in response, my eyes heavy with lust. “Yes, Sir, it’s all for you.” I said, arching my back to push my body against his hand. “I’m so wet and ready for you.”
“Have you been thinking about me or those little boys ogling you out there?”
Jealousy? Was this sudden lust all fueled by jealousy? I bit my lip and tried to look innocent.
“What boys? I didn’t see anyone but you.” I did not argue that they were really young men, because what would that have proved?
He just wanted my loyalty, my fidelity, my subservience. Since he was stealing me from my husband, maybe that was natural. He needed to know I wasn’t just a whore who jumped from Leo to Papo to him to whoever.
“I think of you all the time, Sir. I can’t help it,” I admitted, my voice barely above a whisper. “I think about you fucking me hard, making me scream your name. I touch myself at night, imagining it’s your hands on my body, your cock inside me.”
“Have you done what we talked about? You haven’t let that husband touch you, right?”
I shook my head quickly and violently, my long blonde ponytail swishing around my shoulders. “No, baby, he’ll never touch me again,” I promised, my eyes wide and sincere. “I’m committed to you. You collared me. I belong to you now. I only want you.”
I heard the sound of a zipper go down and my heart leapt. I knew that he could see my eyes change from groveling to anticipation, hunger and desire.
I felt his warm firm cock head rub along the reddened flesh of my ass. “Do you think you deserve this cock, little girl?”
I nodded eagerly, looking back at Sir through the mirror with a pleading expression. “Yes, Sir, I’ve been a very good pet,” I whined, arching my back again and rolling my hips to push my ass out invitingly against his cock. “I’ve been such a good girl, waiting for you and only thinking about you. I need you to reward me by filling me up with your big, hard, perfect cock.”
His cock slapped my ass and then rubbed some more getting closer and closer to its intended target. “Oh God, yes, baby,” I moaned, wiggling my hips enticingly. “Please, give me your cock. I need it so badly.”
I could see his face looking straight down with determination and felt his thick shaft push slowly into me. I gasped out sharply as my wet, aching pussy was stretched to its limit. I would never tire of that feeling.
My head rolled back and my eyes with it.
“Oh fuck, baby, you’re so big,” I moaned. My inner walls clenched around him as he sank deeper inside me.
“Is that what you wanted, little girl?”
I let out a low, needy moan as Sir filled me completely, his cock throbbing deep inside my pussy. “Yes, baby, I wanted it so much,” I whimpered, looking back at him through the mirror with a pleading expression. “Please, fuck me hard.”
“Who’s my little pet, then?” He asked, slamming his cock into me and holding it there.
I shivered as Sir teased me, feeling utterly owned and possessed by him. My eyes glazed over with lust and adoration. “I’m your little pet,” I moaned, my voice breathy and needy. “You are my lord and master.”
He grabbed my ponytail and yanked my head back, turning it towards him. My lips parted in a silent plea for a kiss. I longed for the validation his kiss would provide.
“Please, Sir,”
“Please what, pet?”
I whimpered, my voice trembling with need. “Please kiss me, baby. I want to feel your lips on mine, to taste you as you fuck your beloved pet.” I looked up at him through wet lashes, my expression vulnerable and pleading. “I need you to claim my mouth as you claim my body, to show me that I’m truly yours.”
“Ohhhh, you’re fucking mine, bitch.”
I shuddered at Sir’s possessive words, a thrill of excitement running through me. I felt his grip tighten on my ponytail, and let out a soft moan, eyes fluttered closed in anticipation.
“Yes, baby, I’m yours,” I whispered, my voice filled with submission and desire. “All yours to use and claim whenever you want.”
He leaned forward, pinning me hard to the counter, and our lips met. I moaned softly at my master’s powerful treatment. Sir’s forceful dominance made me weak in the knees.
I ground my ass back against him, surrendering completely to his powerful masculinity. My continued moaning was muffled against his lips as he plundered my mouth with his tongue, claiming me utterly.
“I fucking want you, Ana. All of you. Do you understand?”
I moaned deeper into his kiss, and my body felt like it was melting into Sir’s as he pinned me down. I submitted to his dominant kiss, our tongues waltzing together. When he finally pulled his face away, I was left breathless and trembling, eyes glazed over with desire for him alone.
“Yes, Sir, I understand,” I sighed with pure happiness. I could hear the need in my own voice. I needed this man like no other. I didn’t even know how that happened, but I knew that it was true.
“I’m gonna fuck you anytime I want. And I want to be with you all the damn time.”
His possessive words made me tremble with desire. He wanted to own me. To have me. To hold me. “Yes, baby, fuck me anytime you want. I’ll always be ready for you, always wet and aching for your cock.”
I looked back at him through the mirror, my eyes burning with hunger. I needed him to see the sincerity in my face as I made that promise to him.
He slammed his hips into my ass in an aggressively animalistic way. I gasped sharply and spread my legs wider as his flesh slapped into my mine, the force of his thrusts causing the sink cabinet to bang against the wall.
His eyes widened in the mirror, highlighting the dominant expression on his face as he fucked me hard and fast, using my body for his pleasure. I grabbed the sides of the sink with both hands and hung on for the ride.
Sir slid one hand up under my sports bra and pushed it up slowly over my breasts. His greedy hands grabbed my tit flesh and used them as handles for greater leverage.
“I’ve had many women in my life, Ana, but not one of them compares with you. My God, you’re fucking perfect!”
My nipples, already hard, became rocks under his touch, aching so hard. His compliment was music to my ears. I wanted to be perfect for him. I was desperate to please him.
“Oh, baby,” I moaned, forcing my ass forcefully back at him, meeting his every thrust. “That feels so good. Use me, please.”
“You like that, pet? You like me to fuck you hard?”
I nodded eagerly, my breath coming in short gasps as Sir’s hand cupped my breast, his fingers tweaking my sensitive nipples. “Yes, baby, I love it,” I moaned. “I love feeling your hands on me.” I bit my lip as my eyes fluttering closed in pleasure.
“I love these big perfect titties,” he said, slamming his cock faster into me. “And I love this tight fucking cunt.”
I was moaning nonstop as Sir fucked me harder, his words making me feel like the dirtiest, most desired slut alive. “Thank you, Sir. I’m so glad I can give you pleasure.”
“You’ll get all of me you can handle, little girl.”
I watched him in the mirror, his eyes dark with lust as he fucked me. I could feel every thick inch of him inside me, and it drove me wild.
“Yes, Sir, give it to me.”
Despite my frenzied need, I tried to take it all in. The sights, the sounds, the smells of that carnal bathroom hookup. I wanted to remember this always as the day I fully submitted to my master.
I wanted to remember the feel of Sir’s big belly slapping against my ass, his cock stretching my pussy deliciously. I wanted to remember how he looked, his face a mask of intense pleasure as he violently took me. I wanted to remember the rancid smell of a public bathroom overwhelmed by the scent of our beautiful sex.
“Does that big cock feel good in your pussy, Ana?” He asked breaking my reverie.
“Yes, baby, it feels so good,” I moaned, my hips bucking back to meet his thrusts. “You’re so big and thick, stretching me open. I love feeling you deep inside me. My pussy was made for you!”
“I wanted this pussy all day. I practically ran here to get it.”
I smiled at Sir’s admission, my heart fluttering with joy. “Really, baby? You wanted me that badly? I wanted you, too.”
“Fuck this pussy feels so good!”
The things he was saying were just what I wanted to hear. My pussy clenching happily around Sir’s cock. “Your cock feels so good,” I moaned, my hips moving in time with his thrusts. “Your cock is so perfect. I can feel you soooo deep inside me.”
He pulled one of my arms back and crossed it over my back. Then he took the other and laid it over the first, holding them fast. My face was pushed into the Formica countertop as he continued ramming my pussy.
“Oh, fuck yeah, baby! I’m gonna cum all over you soon, if you keep that up!”
“You wanna cum for me, pet?”
“Yeah, baby! I’m gonna cum all over your big fucking dick, right now!”
“Cum, my little slut.”
I couldn’t do much, all held down like that, but I wiggled my ass the best I could. I heard a loud moan of pleasure burst from my mouth as the climax hit me like a volcanic eruption.
“Ooohh, yesss! Fuuuuuuck yeeessss, baby! I’m cumming for you!”
Sir leaned in and kissed my neck, grinding his big cock deeper into me. I whimpered softly as my body bucked up off the countertop. His cock just kept pushing in and out, driving ridiculously deep into my overstretched pussy.
“Mmm ... Yeeeesss ... I need more ... Harder ... Faster ... Take me, Sir ... I’m yours, Darling ... I love you!!!”
My admission of love seemed to energize my lover like a lightning bolt. He was slamming into my tight young body with a frenzy. My mouth was open in a silent scream as he fucked me mercilessly, each thrust sending waves of pleasure coursing through my body.
“OH GOD, OH GOD, OH GOD!!!”
Sir’s powerful strokes were sending us both over the edge. I squealed with delight as his big cock hit all the right spots and my hips bucking wildly to meet each thrust.
“I’m cumming baby,” he said “Can’t hold off.” And why would he want to. Fill me, I thought. Fill your pet with cum.
“Oh God, yes! Give it to me,” I squealed, as I felt his warm seed splash into me. The intensity of that hot liquid hitting the red-hot back of my pussy, sent me off again.
I remember thinking it was the Fourth of July twice in one week. I saw sparklers in front of my eyes, and felt like I was on the verge of passing out again. I fought it, concentrating on Sir who was panting heavily on top of my back.
“I didn’t like those boys looking at you,” he said softly into my ear.
What? I blushed at Sir’s jealous words, but a shiver of pleasure ran through my body. “It doesn’t matter, baby. They don’t matter. I belong to you. No one else can ever have me,” I said with great conviction. “I’m devoted to you, Sir.”
“I love you, Ana, my sweet little pet,” he said
My heart skipped a beat at Sir’s declaration of love, a soft gasp escaping my lips. I turned my head back to look at him, eyes shining with unshed tears of joy. “I love you too, baby,” I whispered, my voice filled with emotion. “I’ve never felt like this before.”
Sir smiled down on his possession, and I blushed deeply at his smile, feeling a warmth spread through my chest. “Do I make you happy, baby,” I asked, hearing the needy plea for validation in my words. “I love being your little pet, your plaything. I want nothing more than to please you.”
“You please me, Ana.”
I smiled softly, heart fluttering with happiness. He leaned in and kissed me.
Leo paced back and forth through the apartment, twirling his wife’s wedding ring nervously like a fidget spinner between his fingers. He wondered where Ana had gone. Was she with Anton? Probably, as Sergei didn’t seem to know where she was, or wouldn’t say if he did.
Leo could not believe that she didn’t see right through that duplicitous old fucker. He only wants to get into your pants, Ana, her husband thought. You’re just a trophy to him.
The younger man had come home that evening to find that his wife had cleaned out her clothes and personal effects. The note she left was not very helpful.
Leo,
I feel the trust between us is gone, and I’m sure you feel the same way. While I am disappointed in you, I have no anger or hate in my heart. I truly believe moving on is the right thing to do, and I wish you all the best. I removed my belongings today and contacted a divorce lawyer.
Ana
It was the postcard of breakup notes, being light on details or emotions. This is what it had come to. He wished he could go back and do it all differently. He just still didn’t know what that would have been.
Maybe he could have found a way to confront her earlier without sharing with anyone that he’d read her diaries. It was all water under the bridge now.
He could not believe that this was the end for him and Ana. Dammit, but he couldn’t lose her. There had to be something he could do to win her back. There just had to be.
He still loved her, quite desperately. She had to know that. Despite what she said in the note, he knew she was just mad and disappointed in him. This was something he knew he could overcome if she just let him.
The problem was the presence of that fucking old man. Leo saw now that Sergei was never a threat, but he was a stepping stone to the guy who was. Still, Anton may be rich and have a big dick, but he was old and not that attractive.
