We'd been married for almost two years when I caught her. I had been out of town on business and was scheduled to get home late. A canceled flight is normally a disaster, but in this case the airline was able to book me on a direct flight that actually got me home hours earlier than my initial itinerary. I figured I'd keep quiet and surprise Sharron when I got home.
I knew what was happening the moment I entered the door. The sound of skin slapping together. Sharron's guttural cries, somehow even deeper and more animalistic than normal. She had always been vocal in bed but this...this was a whole new level. Hearing those sounds coming from my bedroom, my stomach dropped, sweat beaded on my forehead and, I'm embarrassed to admit, my cock stiffened in my pants. I felt nauseous, but aroused. My hands shook as I grabbed the banister and began to climb the stairs.
Our bedroom was at the end of the hall, the open door facing the staircase. Sharron, my wife, was on all fours in the center of our bed. Her golden brown skin glistened with sweat. Her deep brown and incredibly stiff nipples jutted out from the tips of her breasts as they swung underneath her. I could smell her arousal from the top of the stairs.
Behind her was a large black man. The muscles on his broad back stood out from stain. His ass clenched and unclenched as he thrust into her. His impossibly large testicles swung back and forth, slapping her clit as he plowed into her.
"Oh, God. Oh, God. Oh, God," she began to babble. "Ohhhhh. That's it. That's it, baby. Keep fucking me. Fucking me so good. Yes. Yes. Yes! Aaawwwwhhhhhaahh!"
She was cumming. She was cumming on his cock. Cumming like she never did for me, and as she did he thrust into her and held it. I raised my hand and stumbled forward as if I could somehow stop it. He held himself there. His cock buried to the hilt in my wife as I watched his testicles pull up towards his body and his perineum begin to pulse. He was coming inside her. He let out a low groan as she whispered, "Yes, baby. Do it. Fill me up. Fill me up with your cum."
His orgasm seemed to stretch on forever, but finally his balls began to relax and the pulsing slowed and then stopped. He held her still underneath him for another moment and then began to withdraw. That's when I saw it. His cock slid out of her, and slid out of her, and just kept sliding. When the large plumb like head finally reached her opening, the largest, heaviest looking cock I have ever seen flopped out of my wife and dangled below him. Even as it deflated, it must have been ten inches. Maybe a foot. The shaft was a deep, deep brown and was easily as thick as my wrist. The head was a purplish color and flared out dramatically below the blunt rounded tip.
I felt light headed. My vision began to blur. As my knees hit the floor I was aware of only two things. Sharron's far away voice calling out my name and the painfully intense erection inside my pants.

I awake in my bed, my wife at my side. My face is pressed up against her breasts. Still in a daze I open my mouth, letting her nipple slide in. She coos soft encouragements to me as I suck on it, feeling it getting harder and harder. Her hand begins to slide down my stomach, reaching for me. My pants are undone. I feel her hand wrap around me, squeezing me gently at first, then more firmly. I begin to rock back and forth, humping my cock into her delicate brown hand. That's when it all comes flooding back to me. My wife cheating on me. The intensity of her orgasm. That cock. That massive black cock.
I start to push away from her. "Sharron. Sharron, how could you," I plea as I move.
She grabs me, holding me close. "Oh, baby. I'm sorry, baby."
"You're sorry? Why did you... How could you..."
Sharron grows quiet for a minute. "Listen, Glen. I'm going to lay it all out for you. I want you to listen to me carefully, then we can talk." She gathers her thoughts. "You know I love you, Glen, and that I love our sex."
"Not just ours, it seems."
"Glen, I...no. You're right, not just ours. You give me so much, and I love you for it, but I need...I've always needed something more. Throughout my life I've been with a fair number of guys. You know this. Some white, like you. Some black, like me. I fell in love with you. I love our life. I love our sex. I love what we share. But, on occasion I just need more."
"How long has this been going on."
"It's always been going on," she says quietly. I turn away from her. "It's not often, mind you, but it's always been a thing."
"You've been fucking him for our entire relationship," I demanded.
