I was still feeling bad about having to cut my chat with Sam short last night, so when my last meeting of the day got canceled, I figured I'd surprise her with an impromptu visit on my way home. Heather was already expecting me to be home late, so I didn't even have to worry about making up an excuse.
I checked my phone and saw that I had a few messages from Sam.
Sam: I can't wait to talk later
Sam: I have a fun story to tell you
Sam: At least I hope you'll think it's a fun story :P
I smiled to myself, feeling a tingle of excitement as I wondered what kind of story she had to tell me. It made me that much more eager to go see her, so I wouldn't have to wait much longer to find out.
Mark: Can't wait to hear your fun story :)
I kept my response simple for the time being, not wanting to give away my surprise just yet. After another 15-20 minutes of responding to emails and checking in on a couple of projects, I was ready to head out for the day.

I got lucky with a parking spot right outside Sam's building and checked my phone. She hadn't read my message from earlier, so I wondered whether she might still be at work. I tried texting again, hoping I'd get a response soon if she had her phone on and could hear the chime.
Mark: I have a surprise, too
Mark: My last meeting got canceled, and I just parked right outside your building ;)
Then I wasted some time scrolling through social media and news articles on my phone while I waited to hear from her.
I gave it a few minutes, but still no response, and no sign that Sam had read my messages. Maybe she ended up having to work late, or she stayed after her lifeguarding shift to work out at the gym. That was the risk of planning a surprise visit, I guess.
I tried one more message.
Mark: Still on your way home from work?
It was a nice day at least, so I got out and walked towards the park while I debated about how long I could reasonably wait around before I'd need to head home.
Then, as soon as I stepped out of the car, I heard what sounded like distant moaning sounds, probably coming from an open window nearby. I smiled to myself as I looked up, trying to find the source. The first thing I noticed was that Sam's bedroom window was open. Could the sound be coming from there? I kept listening, but the traffic and other city noises bouncing off of the buildings made it difficult to tell.
Just then, the front door to Sam's building opened as one of her neighbors was on their way out. Instinctively, I jogged over to catch the door before it closed.
I made my way up the four flights of stairs, noting that the moaning was definitely getting progressively louder. My cock stiffened instantly, and I had to adjust as I kept climbing.
I think I knew the truth in my gut already, but my mind kept coming up with other plausible explanations. Maybe it was Sam's roommate Molly hooking up with someone. Or maybe Sam was alone and masturbating.
But as I reached the door to the apartment and continued to listen, I heard the unmistakable, familiar sound of Sam's moans and another male voice inside.
"Fuck, I'm going to cum again! Your pussy feels so good gripping my cock like that," the guy said.
"Yes! Do it. Fuck me and fill my pussy with more of your cum! I'm going to cum again on your giant cock! You feel so good filling me so deep like that!"
That was definitely Sam.
There was a tightening feeling, both in my chest and in my pants, as I felt overcome with jealousy, rage, hurt, and arousal all at once. I leaned in and listened closely to see if I could hear a name, wondering who the guy was. I had to assume it was her neighbor, Chris. Unless she was keeping even more secrets from me.
There were some loud grunts, growls, and moans, and then I heard him cumming. Likely in her pussy, as promised.
"I'm cumming, too!" I heard Sam yell next.
"Yeah, cum on my cock, Sam! Make me feel it," he replied.
Then her moans got steadily louder until I heard her letting go and cumming loudly, not concerned with holding back.
Just then, another door opened on a floor below, and I heard footsteps on the stairs. I knew I couldn't stay there much longer without risking getting caught listening at Sam's door with an obvious erection like some kind of pervert. After briefly entertaining the thought of knocking and breaking things up in there, I forced myself to leave instead. I wasn't even sure what I would say or do if I confronted her at that moment, and thought that a semi-public fight with my college-aged mistress would not be a good look.
Once outside, I got back into my car quickly, and just sat there feeling stunned, my imagination reeling with what I'd just heard. I'd left the car windows open a crack and realized I could still hear Sam's moans faintly from there. It sounded loud enough that she might be cumming again already.
Without another conscious thought, I reached for my cock and started rubbing and squeezing it through my pants. I'd barely started touching myself when I suddenly felt myself exploding in my underwear with a muffled groan.
Fuck. What the hell was that? I looked all around in a panic, making sure no one had seen me touching myself in my car. Then I took a deep breath and leaned back in my seat, feeling the cum oozing in my underwear.
My reaction confused me, first and foremost. I just found out Sam was fucking her neighbor behind my back. I was angry and jealous, but it also made me cum really hard in my pants, like a horny teenager. There were a lot of conflicting thoughts and emotions overwhelming me suddenly, but I turned it all off for the time being, knowing I had to get home.
I picked up my phone to send one more text to Sam before heading out.
Mark: Sounds like you're busy, guess I'll head home
No way she'd misread that.

When I got home, I cleaned myself up quickly in the bathroom without Heather noticing anything. I didn't want to take a shower right away, knowing that might appear suspicious, so I just did the best I could with tissues at the sink.
Trying to act casual was difficult; I couldn't stop checking my phone, waiting for the read receipt to show that Sam had finally seen my messages. I felt eager to see how she'd respond, but my anger kept building as more time passed with no changes.
Every time I thought about the sound of her moans and the way she was practically begging Chris to cum inside her, I started getting hard again. I had to keep forcing myself to focus on other things.
Just as I was sitting down to dinner with Heather and the kids, I finally heard my phone chime with a text. Then another. I hesitated for just a moment, but then decided to ignore it for now. If it was Sam, she deserved to be kept waiting and stressed for a little while.
"Aren't you going to check that? Think it might be work?" Heather asked, clearly used to my excuses for checking my phone throughout the evening.
"Nah, it can wait," I replied, forcing a smile.
She smiled warmly back at me, and we went on eating and talking.
Afterwards, I helped to get the kids to bed. I could still feel my frustration bubbling up just below the surface, and knew I needed more of a distraction. So, as soon as the kids' lights were off and doors were shut, I grabbed Heather by her wrist in the hallway, keeping her from heading back out to the kitchen.
When she turned back to look at me, I waggled my eyebrows suggestively.
Heather laughed and then sighed as I pulled her into my arms, ready with an excuse. "The kitchen's a mess..."
I held her to me by her hips, pressing my erection into her as I leaned in to kiss my way up her neck. "I'll clean up after. And you can go to sleep."
Apparently that was a good enough offer, because she let me pull her down the hall the other way, into our bedroom.
I struggled not to let out too much of my frustration or anger towards Sam as I tugged Heather's clothes off and pushed her back onto the bed. Normally, I took my time turning her on, making her cum a couple times before I even entered her. But tonight I needed something different.
I climbed on top of my wife right away, pushing her legs apart with my knees and grinding against her as I kissed her roughly, taking her bottom lip between my teeth.
She pushed back on my chest and made a slightly irritated sound. "Mark, slow down..."
I groaned and forced myself to rein it in a bit more, reaching down to run my palm over her mound, my fingers rubbing and pressing in along her slit. "I need to feel you," I said, hoping that would help turn her on.
Sure enough, Heather moaned as I kept working my fingers and kissing her neck. I pressed a finger into her opening and felt her getting wet, so I kept going, easing a second finger inside. I tried to make her cum fast, curling my fingers to rub against her g spot while my thumb rolled circles over her clit, listening to her panting and moaning and adjusting accordingly.
As soon as I felt and heard her cumming on my fingers, I pulled back and gripped my throbbing cock, pushing into her hard and fast with a groan. Then I finally let myself think about Sam again, imagining her getting fucked by her neighbor with his big cock. Hearing her moans and begging, imagining the look on her face as he was filling her so deep.
With each thought about Sam, I heard myself moaning, felt myself thrusting harder and faster into my wife. It seemed like I was grunting and cumming inside of her within seconds, for the second time that evening.
I held myself up over Heather for a few moments afterwards, breathing hard. I was almost afraid to look her in the eyes, worried about what her expression might be. Whether I'd given myself away at all, with this frantic fucking.
"Guess you had a stressful day," she said.
"Yeah, you could say that," I scoffed, rolling off of her.
"Feeling better now?" she asked with a coy smile.
I finally broke, knowing I needed to do better for her. I smiled back, leaning in to kiss her again, more softly this time. "I am. Thank you."
She just smiled sweetly up at me, and held onto my arm as I pulled back, leaning up to kiss me again.
