I finally decided to creep down the side yard, eventually arriving at his living room window. There was a fortuitous gap in the curtain - or so I thought.

What I saw shook me to my core, but it also nearly made me faint from arousal. Bob and Anna were sitting on his couch. The first thing I noticed was that my wife's nightie was pulled down to her waist - her beautiful big tits exposed. Bobs massive mitts were pawing them, massaging them, pinching her nipples. I could make out my wife's faint moans through the glass as she titled her head back in pleasure. In a horror I realized that Bobs shorts were around his ankles, and his massive cock was exposed and towering upwards, impossibly big. I nearly collapsed when I saw Anna's delicate hand was wrapped around it. She was pumping him, her fingers slowly massaging up and down his impressive shaft. His hefty scrotum jostling up and down with her strokes. Her small fingers had no way of encircling all the way around his thick girth, but she stroked him passionately nonetheless.

My mouth had gone dry, my eyes wide, my knees weak - but before I could even react, Bob exploded. I witnessed his incredibly heavy balls pull upwards, pulsing, as a torrent of his cum unloaded from his engorged head. Rope after rope of thick seed showered down into both of their laps, coating Anna's hand as she pumped him to a satisfying completion.

I sprinted back into our house, nearly diving onto the couch in our living room, trying desperately to appear composed.

I soon heard the sliding door open slowly, and I saw my disheveled wife walk into the room. Her hair was a mess, and her breathing heavy. The nightie was ruffled, and her face and eyes displayed a terrified expression.

I had never been so attracted to her. I stood, saying nothing. I grabbed her by the arm and threw her down on the couch, "T-Tim. W-wait..."

"Shut up." I said, lifting her nightie and exposing a sopping wet pussy, I flipped her over and buried myself in her sex with an unbelievable urgency. I had never felt her so soaked, she was beyond wet.

"God damn it Anna. I fucking love it when you act like a slut." I slapped her ass harder than I ever had before.

She sat up, gathering herself. She was nervous, and awkward, still breathing heavily. "I... I went inside and we were in his kitchen, mostly." She was stuttering as she spoke, "H-He, was brushing against me a lot in the kitchen, and I could feel him. He was excited." she covered her face in embarrassment.

"Its okay baby, I want to hear. Tell me."

"He came up behind me, and started playing with my boobs... It...It kinda got me kinda hot, and i was too embarrassed to tell him to stop."

I couldn't believe it. "Did he say anything?"

"He uh... um, he just said that he loves my tits, and that he can't get enough of them..." she paused, clearly excited by the memory.

"Once I finished with the food I covered the lid and set it to stew for a few minutes. I turned but before I could try to leave he pulled me into the living room sat me down on the couch."

She was blushing deeply, fidgeting in her seat as she explained it, "H-He kept playing with my boobs, and I just sat there, frozen. He stopped for a second and quickly pulled his shorts down, and his honker flopped out."

A few seconds passed, and I received a reply, "Being naughty", she closed the message with a smiley face wink.

My blood pressure immediately shot up, I tried to look over into Bobs house but I couldn't make out much.

"What are you doing?" I replied.

I paced around the room, a minute went by, and then I received a message.

It was a small phone video, more arousing than any porn. My wife was kissing Bob's massive shaft up and down, wrapping her lips around his member and stuffing as much of his meat into her mouth as she could. Her small hand was massaging his heavy balls as she blew him. The noises of her suckling sent me over the edge, and I instinctively dropped down onto the couch, exposing myself. My wife was using her mouth on our neighbors manhood.

I heard Bob through the recording, "Mmm. Fuck yeah baby. Suck that big cock."

It looked as if Bob was holding her phone out in front of them, but the only view I had was of his large cock, and my wife's face, lips, and tongue providing it with pleasure.

She smiled, giggling again, "I need to go brush my teeth baby, he came a lot." I looked on as her beautiful ass strode up the stairs.

I had a feeling it was going happen, and on the next Sunday, it inevitably did. My wife was frolicking naked around our pool, as was our neighbor. They were in and out of the water, kissing, petting. Bobs massive cock was on full display as he bounced around the patio. My wife showered it with playful compliments all afternoon. On occasion she would come over and sit with me as I laid out on one of the pool chairs, flirting with me in a buzzed state of erotic relaxation. We had all been drinking, Bob's famous Moscow Mules were flowing heavily. It was an incredibly bizarre afternoon, but I was erect for nearly the entire duration of it, especially when I noticed the two of them quietly playing with each other under the waters surface. It was a surreal afternoon to say the least. We had gotten a late start on this particular Sunday, and before I knew it, dusk approached.

Suddenly, I awoke, it was night. I shook my head, looking around the patio and seeing no one. I stood up, groggily, the alcohol still lingering in my system. At first I heard silence, but that was quickly interrupted by a distant moan. It was muffled, but I was fearfully sure it was my wife. I panicked, not knowing where it was coming from. I ran into the house, looking around for her. She wasn't in the living room. I bolted up the stairs into our bedroom. She wasn't in there either, why would she be? I stood for a moment, wondering, and just as I was turning to leave, I saw them.

I suddenly realized that my jaw was wide open. I looked on in horror as Bob reached around, clutching her breasts, pulling her up into him as he fucked her.

"You like that baby?" Bob said. I could barely hear them, but their lips provided the context where the sound failed.

"I love it." my wife replied.

He slowed, pulling out of her and spinning her around on his bed, he laid her down on her back. Her pussy looked swollen, inflamed, and soaking wet. His massive organ was coated in an unreal amount of her cream, there was almost a full lather along his shaft. I had never seen Anna yield so much of her womanly essence before.

He leaned down and kissed her breasts, and then her mouth, as he aligned his behemoth at her sex once again, slowly shoving himself inside of her. I watched in aroused fascination as his thick shaft spread her open, her soaking labia stretching and hugging his meat, never letting go. Her juices and her need caused her pussy to cling to his organ. Her womanhood craved his large cock.

Anna's moans became fever pitch, and her squealing was giving way to something powerful looming in her loins, an orgasm brewing of the most intense magnitude.

"Oh! Oh! Oh fuck! Bob! You're gonna make... I'm, I'm gonna... I'm cumminggg!!" Her moan was primal. I looked on as her legs wrapped around his lower back, toes curling and locking downward. Her body erupted in convulsions as the most powerful orgasm of her life swept over her.

Bob roared, joining her in sexual climax, "Fuckkk Anna, I'm gonna cum in this married pussy baby!" His large balls unloaded, unleashing what had to be a massive load of seed, deep into my wife's willing womb.

They embraced and kissed passionately, eventually rolling off and laying at each others side. Bobs massive organ now lying limp and large across his thigh. My wife was breathing heavily, and I thought I could make out her pussy still quivering from the bombardment it had just received. He rested his hand on her tummy, chuckling, smiling wide.

"I think I stretched that married pussy out a bit. Did you like it?"
