My ten year marriage to Angie has been perfect in every way apart from my inability to make her orgasm. She loves our sex life and gets very wet and excited and always looks lovingly into my eyes when I finally spurt my cum into my beautiful Jamaican queen but in all our lovemaking there's been no climax for her. She has always told me its not an issue for her although I know, because I've asked her, that her previous lovers (all black) had made her cum. "It's the bull in them" she explained. Over the years I've questioned her about them. Was the sex better? She answered that it was better but it was sex not love making like ours. I asked if she missed coming. She answered yes. I asked were they all bigger than me. Yes. I asked did they last longer. Yes. Then 6 months ago I finally asked the question that had been in my head for many years and confused the hell out of me. Did she want to be fucked by a "bull" again? 90% of me wanted her to say an emphatic no but without hesitating Angie looked me straight in the eye and said "Yes". It was for me to find him and make all arrangements. Through swinging heaven I found and met Calvin, like us, in his forties, a fit tall muscular black man, very stern and domineering. I had clear limits, it would be a hotel, condoms, respect her etc. Calvin shook his head. It would happen in my marital bed, bareback, and he'd treat my slut wife as he wanted. Like a complete wimp I accepted and a date was set. I couldn't have felt more in love watching Angie's mounting excitement as we got nearer to the date although I felt sick with nerves. On the day she filled out room with candles, fresh bedding, she showered and as the time got near got into a sexy red negligee. When the doorbell rang she posed sexily on the bed while I let Calvin in. He dismissed my offer of a handshake and brushed past me and straight into the bedroom. She smiled her brightest welcoming smile saying "hi". Calvin took in the view and gave only the hint of a smile on return and gruffly said "perfect". And perfect she looked. Five foot eleven, 38f. Perfect long legs and round ass. Dark skinned Caribbean beauty. He undressed and got onto the bed next to her. His cock was huge, probably 11 inches but Angie showed no fear at its sight, her eyes opened wide in appreciation. It was thick and veiny with massive balls underneath. I'm not at all bi but even I thought it was beautiful. They kissed, he was rough and aggressive but Angie didn't seem to mind. He mauled her huge black tits, bit them. She moaned in delight never once taking her eyes off his. He roughly rubbed her clit and again she moaned. "Lick my ass" he ordered her straddling her face, she held his hips and I saw her pink tongue dart into his asshole. "Undress" he ordered me and I meekly complied. He looked disparagingly at my hard 6 inches and sucked his teeth. "Lick her wet for me" he ordered. This I did happily. I'm good and Angie responded well although still no orgasm but her juices flowed. He dismissed me with a wave of his hand and I sat in the corner chair. He turned so his cock was near Angie's face and he slapped her sweet face with it several times. "He ain't satisfying you with maggot dick is he?" She shook her head. "You always been faithful to him" she nodded. "Stupid bitch. You ready to be fucked right? " she nodded. He slipped down her body and struggled to find her entrance with the bulb of his mighty cock. I felt sick but my cock was fully erect. With one thrust he pushed all the way into her. She screamed. I jumped up but Calvin just pointed to my chair and I complied by sitting down. "Oooohhhh" moaned Angie as he remained still deep in her. Her legs wide open, toes curling, eyes screwed shut in a painful grimace. He maintained his position. "You ready baby?" She nodded, her red nails digging into his back. "Wonna be fucked good" he started to move slowly in and out, she nodded. "Wonna cum on real cock?" She opened her eyes and looked into his. "Yes" she said kissing him. "Show him what real fucking is?" Her legs wrapped around and between kisses she cried "yes yes YES YES FUCK ME". " good slut" he smiled. He began to piston in and out of her, I moved to see better how his glistening black dick almost turned my wife's love hole inside out. She was totally engulfed as for ten minutes he pumped away and she squealed in absolute delight in a way I'd never managed to make her do. The fucking became more urgent, he looked at me and said "she's close". Angie finally seemed to remember I was there and looked at me with beautiful lusty eyes. She beckoned me with her finger saying "please". I went to her and kissed her gently on the lips, she looked in my eyes and told me she loved me. At this Calvin increased the pace so his cock was just a blur fucking wildly into my wife. She faced him crying out loudly. I supported her head and touched her smooth flat tummy excited that another man was inside it. She opened her legs wider and screamed "I'm coming!!!" Squeezing and biting my hand as her orgasm lasted an age with Calvin pushed deep into her. As it subsided he called her a fine slut. I knelt by the bed and she cuddled into me kissing and thanking me. Calvin withdrew leaving her cunt gaping and began to pump his cock by hand. I wasn't worried, I was holding my lovely satisfied wife. But then Calvin said "open your mouth bitch" Angie complied as his balls exploded hot cum all over her face and some on mine. He gave a low groan as the stream slowed. Then he slapped Angie around her face sending drops of spunk into my eye saying "you're mine slut" before I could get angry she smiled happily up at him "I know" she said. He climbed off the bed. " clean her boy". I was going to get tissue but Angie grabbed my arm " clean me properly Steve" she said kissing me. Understanding I licked the cum from her face and she returned the favour. We took turns eating it out of each other's mouths. Calvin watched. " he's a good boy" he said. Angie smiled at me lovingly looking so wonderful in her post cum happiness covered in her Bulls spunk. "He is a good boy" she smiled.
