The guilt of what happened in my office was hanging over my head for weeks. Little did I know, Cari had been recording our encounter on her phone the entire time and she sent me the audio file on my business email. I was in agony listening to the things that I said about her and about Haley, and the sounds she made while I pleasured her right there on my desk. I knew I couldn’t let something like this happen again, but what could I do when she had this proof? On top of everything else I found a strange file on my computer full of nude and suggestive pictures of Cari that she found a way to leave there for me to find. She was tricky, sneaky, and she knew exactly what she was doing.
My situation was only made worse when Cari’s apartment flooded and Haley offered to give her our spare bedroom for a few weeks while she figured things out. All of this was sprung on me when I came home from work one day and found Cari sittin on the couch in nothing but a long white t-shirt. Her hair was wrapped in a towel and she was sprawled out on my couch with a magazine.
“Hmm, welcome home, hubby.” She tittered, giving me a little wave.
“Woah. What the fuck, Cari, Haley is going to be-“ I was cut off by my wife walking into the room in her robe and slippers.
“Oh, sweety, you’re home! So I know this is last minute but Cari’s apartment flooded today, some stupid issue with the pipes next door. So I told her she can have the guest bedroom until they get all that figured out and replace her carpets and everything. You don’t mind, do you?” She asked, pouring her and her sister and myself each a glass of red wine. My eyes darted back and forth between Haley and Cari and I gave my wife a nervous smile.
“Sure. Why would I care? No big deal.” I shuffled off to the bedroom and spent the rest of the night rocking back and forth in the shower with my head in my hands.
Cari was surprisingly hands-off for the first week that she was in the house. Nothing but sly smiles and subtle glances while Haley was around. We were even left alone one night while Haley was at book club and all she did was lay on the couch in her satin robe and tease me with her bare legs. I thought that what happened in the office may have finally been the last of it, that she just wanted something to hold over me and now it was done.
This is, however, until one night when I was in the kitchen making sandwiches for the kids lunches the next day. Haley was expected home from work at any moment and I thought it would be nice to get some things done before she arrived so that we could spend some time together. I had just packed up a bag for each of my kids when Cari walked into the room.
She was dressed fairly conservatively in a pair of black yoga pants and a mustard yellow button-up blouse. She held her phone to her ear and walked casually over to me.
“Yeah, yeah ok. Well he’s right here so I’ll just pass you over to him. K, talk to you later doll face.” She spoke to the caller. “Here, it’s Haley. She wants to talk to you.” She passed me the phone and leaned against the counter as I spoke to my wife.
“Hey honey. So, I’m running late here, I don’t know if I’m going to be home for dinner so just order pizza or something for the two of you and make sure the kids have salad with theirs.”
I gave her short answers in agreement, but soon my attention was diverted. Cari was creeping forward closer to me, her fingertips crawling up my chest and her lips gently pressing against my neck as she sunk into me. I tried to swat her away while still replying casually to Haley as if everything was fine.
“Yes, yes. Ok I’ll do that. See you when you get home.” I attempted to end the conversation quickly.
“Hang on, there are a couple of things I need you to do tonight…” Haley went on. I listened closely, making sure to catch key words as Cari distracted me.
She ran her hand down my body and I knew I couldn’t let Haley hear anything. I kept as quiet as possible as Cari unzipped my pants and eased my cock out of my boxers. I took a deep breath in and clenched my teeth, nodding and giving Haley periodic “yup, uh huh” responses. I gripped the edge of the counter while Cari stroked me slowly, working my penis into a throbbing erection as I listened to my wife’s list of chores.
“The kids have soccer practice and I won’t be able to pick them up so you have to go get them in about half an hour. You can get there in time, right?”
“Mhmm. No problem.” I hummed. I never realized how difficult it was to sound normal while someone was jerking me off in secret. I was stifling moans and grunts, leaning back into the counter and shaking my head as if Cari would suddenly care that I was uncomfortable. She smiled and even giggled in my ear as she played with my engorged tip. I turned my head to look at her, begging her with my eyes to stop.
She did something in that moment that I never thought would happen. Her lips enveloped mine, kissing me soft and teasingly as my wife’s voice echoed in my ear. I did everything I could to be silent as her tongue slipped into my mouth. She tasted sweet and our tongues intertwined in a shameful and passionate kiss.
“Do the kids have their lunches all ready for tomorrow? Because they don’t like the apples I bought so make sure they both have a banana instead, ok?”
“Mhmm.” I agreed, Cari nibbling on my lower lip. My mind raced with the guilt of what I was doing, but my main focus was on keeping everything quiet so Haley wouldn’t suspect what was happening on my side of the phone. Cari’s hand grasped my rock hard manhood and I felt myself leaking over her fingers.
Her lips parted from mine and I let out a sigh as her stroking became quicker and tighter. I bit my lip and squeezed my eyes shut, listening to Haley prattle on about bananas and lunches. It all sunk in what Cari had been saying all this time, that all I got from my wife was work and chores and nagging while her own sister gave me pleasure and sensuality. I knew, still, how wrong this was, but listening to Haley go on about cleaning and errands while this beautiful young woman worked my gushing cock made me give in.
“Did those packages come today?”
Cari’s grip was perfect and I held back my heavy breathing as best I could.
“Yes, yes.”
Her hand sped up and she licked all the way up my neck, her braless chest pressing against my arm. I couldn’t help but remember what her perfect, round tits looks like as they bounced while I fingered her on my desk.
“And what about the cheque I was expecting, did you check the mail?”
My leaking was out of control and I was glazing Cari’s knuckles as she brought me right to the edge.
“Wh-what…” I could barely hold myself together and soon I was holding back animalistic grunts.
“The mail, come on…tell me you checked the mail.”
“I, uh…I…” Everything built up like a bottle of soda being shaken to the point of exploding. Cari whispered ever so quietly in my ear and soon I couldn’t contain myself.
“Let go.”
“Well, did you?!”
“Yes. Yes, yes!” The wave of pleasure crashed over me and I blew my load all over Cari’s hand. I spurted string after string of cream that splattered onto the kitchen floor and I breathed heavily and uncontrollably into the phone.
“Ok ok, then just leave the cheque on the kitchen table for me. You’re breathing really heavy, are you ok over there?”
I inhaled deeply and reassured her that I was fine and just tired. Cari looked down at the mess I had made and then leaned in close to the phone.
“Don’t forget to mop the kitchen floor too, it could use a good cleaning.” She teased with a devilish grin.
“Oh, sure that would be great sweety. Well I’ll be home in a couple of hours. Have a good night!”
Haley hung up the phone and I leaned against the counter, breathing heavily and staring at the shameful mess I had made on the floor. Cari stood in front of me and I passed her back her phone. I stared at her with an expression of regret in my eyes as she licked up the cream I had left on her fingertips. She walked towards the hallway and I was left alone and ashamed with my cock hanging out of my pants and a reminder of my infidelity coating my kitchen floor. Cari walked out of the room and said only one thing before she disappeared for the night.
“Better grab that mop.”
