My ex-wife Lisa called me two weeks before her wedding. She didn't waste time with small talk. "I'm marrying Marcus," she said, her voice low and excited. "He's black, hung like a horse, and he fucks me so hard I can't walk straight some days. You should come to the reception. Watch what you lost."
I showed up anyway. The ceremony was over, but the hotel suite after-party was packed with their friends. Lisa looked stunning in a tight white dress that barely covered her ass, her tits pushed up and on display. Marcus stood beside her, tall, muscular, dark skin gleaming under the lights. When he caught me staring, he smirked and pulled Lisa close, grabbing her ass right there in front of everyone.
Later, when most people had left, Lisa dragged me into the bedroom. "You always wanted to see this," she whispered, already unzipping Marcus's pants. His cock sprang out, thick, veiny, and easily ten inches long. She dropped to her knees and started sucking him without another word, slurping loudly, spit running down her chin as she tried to take him deeper.
Marcus looked straight at me. "Strip and sit the fuck down," he ordered. I did. My own dick was already hard and leaking as I watched my ex-wife gag on that black cock. She pulled off for air, strings of saliva connecting her lips to his shaft. "God, I love this dick," she moaned. "So much bigger than yours ever was."
She stood up, hiked her dress over her hips, and bent over the bed. Marcus lined up behind her and slammed in with one thrust. Lisa screamed, her body jerking as he stretched her pussy wide. He fucked her hard and fast, the wet slapping sounds filling the room. Every time he bottomed out, Lisa pushed back, begging for more.

"Fill me up," she gasped. "Show him how a real man fucks his ex-wife."
I stroked myself, unable to look away. Marcus flipped her onto her back, spread her legs wide, and drove back in. Her tits bounced with every thrust. She came twice, soaking his cock and the sheets, before he grunted and unloaded deep inside her. Cum leaked out around his shaft as he kept pumping.
Lisa looked over at me, eyes glassy with lust. "Get over here and clean it up," she said. I hesitated only a second before crawling between her thighs. Marcus pulled out and I buried my face in her used pussy, licking his thick load while she held my head down. She came again on my tongue.
Marcus wasn't finished. He pulled me up, bent me over the bed next to Lisa, and pressed that slick cock against my ass. "You want to know what she feels?" he growled. He pushed in slow and steady until I was stretched and full, then started fucking me the same way he had fucked her. Lisa watched, fingering herself, telling me how pathetic I looked taking her husband's cock.
We didn't stop until morning. Lisa rode Marcus while I licked them both. She made me suck him clean after he came in her again. By the time the sun came up, my ex-wife was officially married, and I was hooked on watching every filthy second of it. She kissed me at the door before I left. "Same time next week," she said. "Marcus wants to breed me while you watch."
