I never expected to watch my girlfriend get railed by her black ex, but there I was, cock in hand, while Marcus slammed into her from behind.
It started when she got a text from him out of nowhere. "Hey, you still think about that dick?" she read it out loud to me, laughing at first. But her face flushed and her thighs rubbed together. We had talked about her past with him before. She always said he was the biggest she'd ever had, thick and black, stretching her pussy like nothing else. I told her to reply. She did, and within an hour he was at our door.
She let him in wearing just a thin robe. Marcus was tall, built, skin dark as night, and when he dropped his pants his cock hung heavy and veined, already half hard. "Missed this?" he asked her, grabbing her ass. She nodded and dropped to her knees right there in the living room.
She sucked him sloppy, spit running down his shaft as she tried to take it all. Her mouth stretched wide around that black cock, gagging when he pushed deeper. I sat on the couch stroking myself, watching her cheeks hollow out. "Fuck, I forgot how thick you are," she moaned between licks. Marcus grabbed her hair and fucked her face, balls slapping her chin.
He bent her over the arm of the couch next, yanking the robe off. Her pussy was already dripping. He rubbed the fat head of his cock up and down her slit, teasing, then shoved in hard. She cried out, back arching as he buried every inch. "Goddamn, still tight," he growled, pounding her with long, rough strokes. Her tits swung with each thrust, ass rippling when he smacked it.
I moved closer, watching his black cock disappear into her pink pussy, stretching her lips wide. She looked back at me, eyes glassy. "He's so much bigger, baby. Feels so fucking good." Marcus reached around and rubbed her clit while he fucked her faster, skin slapping loud and wet. She came hard, legs shaking, pussy clenching around him.
He flipped her onto her back on the floor and lifted her legs over his shoulders. He drove in deep, bottoming out with every thrust. Her moans turned into screams as he hammered her spot. "Take that black dick," he told her, and she begged for more. I jerked off watching his heavy balls slap her ass, her juices coating his shaft.
Marcus pulled out and flipped her again, this time pulling her on top to ride him. She sank down on that thick cock, grinding and bouncing, tits in his face. He sucked her nipples while she worked her hips, taking him all the way. "Ride it like you used to," he said. She did, ass flexing as she fucked herself on him.
When he was ready to cum he pushed her off and stood over her. She opened her mouth and he stroked that big black cock until thick ropes shot across her tongue and tits. She swallowed what she could, licking the rest off him while looking at me. I came right after, shooting on the floor.
We all caught our breath. Marcus got dressed and left with a smirk. She crawled over to me, cum still on her chin, and kissed me deep. "Next time you can join," she whispered. My cock twitched again already.
