Arrived home late that Friday evening about seven months ago. Alex, the hired young black bull who we had used for the wife's first interracial experience a month before, was due in less than 10 minutes. She greeted me at the door looking doubtful and anxious, and immediately asked me, "Are you sure you want him to have me again?" I replied, "You enjoyed it that first time, didn't you?" "Yes," she reluctantly answered, "but I was feeling the same way as now before he arrived and then felt guilty after. I'm not sure having other men is for me. I've always liked our sex together and it's always been enough for me. I don't need other men." I countered, "But once you two got started, you were totally into it and you fucked him back with passion." Her last comment on it just as the doorbell rang was, "Remember, I'm doing this only because you insist." As I turned to go upstairs to change, I said, "That's probably Alex. Give him a hug and a kiss, and then bring him up. We'll start in our bedroom this time." I ran up the stairs and got out of my work clothes in record time. I was stood there in my underwear just finished putting my clothes away when they walked in, the wife leading Alex by the hand with a smile on her face. Her blouse was already unbuttoned and her front opening bra was unclipped and hanging open exposing her breasts, the nipples already hard. Alex had an even bigger smile on his face and his cock looked like it was already almost fully hard under his loose running shorts. They were down in the foyer for only about two minutes and the wife was already into it. So much for her guilty reluctance. Oh, she really was sincere about that, but just two minutes with her BBC and she was panting for it. I grinned at both of them, shook Alex's hand, and said, "I see my wife has greeted you with her usual welcoming warmth, so you two don't need to wait on me. Go for it!" She led him to the edge of the bed where he undressed her whilst they kissed. He slid her blouse and bra off, and then rubbed her cunt through her shorts while she humped his hand in response. He quickly pushed her shorts down her legs and she kicked them off. She wasn't wearing panties - another sign she really wanted to be fucked by another man in spite of her professed reluctance. As he ran his hand down over her cunt and touched up her pussy furrow, he said, "You're already sopping wet. I bet you've been thinking all afternoon about how my big cock felt in you the last time." She moaned in response and he ran his fingers in her pussy groove for a few seconds. Her moans increased, and when he fingered her clit with a circular movement using the pad of his middle finger, she started humping her groin against his hand. It was obvious to me she was ready to be fucked, and Alex knew it too. He plunged two fingers up into her pussy and began finger fucking her. Within just a few seconds, he said to her, "You're already sopping wet for me. Do you want it? Tell me how much you want it!" She moaned loudly and replied, "Yes, I want it. God, I can't wait for it." He fingered her for a few more seconds and her moans lengthened and deepened. Keeping his fingers inside her pussy, he said, "You're close to coming from my hand. Do you want me to finish you off with my fingers, or do you want me to fuck you with my cock?" Her eyes were glazed over and she was hanging on by a thread when she said in a low voice using great effort, "Your cock. I want your cock. Fuck me with your cock. Oh, God, I need it now!" He ordered her to get on the bed on her back and spread her legs for her black 'bull'. He whipped off his tee-shirt and pushed his shorts down, practically flinging them across the room in his haste to fuck her. As he quickly knelt between her lags and lowered his hips to her cunt, she stared glazed eyed at his rigid cock. It was about eight inches of thick, hard meat, a bit less girth at the knob end to make it easier for him to slide it in, and bigger toward the base so the woman would really feel it stretching her when he went deep. Just looking at it approach my wife's pussy opening a she impatiently waited to be fucked by it had made my own cock painfully erect, and I couldn't help slowly wanking it to relieve some of the lust I was feeling. The wife reached for it and pulled it toward her opening. He let her put his knob end in as he held himself up on his arms, and then, when she rolled her hips upward to capture more of it, he plunged in all the way. She loudly gasped at his penetration, snapping her head back with eyes shut and mouth open in a grimace of surprise mixed with lust - just the way a man loves it when he's first penetrating his woman. And there was doubt in my mind as I watched them; she certainly was his woman at that moment. He had claimed her, taken her, and was beginning to fuck her; and the look of lust on her face confirmed that she was now his. As he started thrusting his cock up her, she wrapped her legs around his waist and locked her ankles, intimately joining her body to his. Her hands were reached up and grasping his upper arms. He looked down on her with lust and proceeded to steadily increase the depth, speed, and power of his cock thrusts. It was less than a minute since he had first penetrated her and she was already visibly speeding toward an orgasm. She was loudly moaning and pulling him tighter into her with her arms and legs. Her eyes were tightly shut and her lips and teeth were rigidly set in a grimace of lust and approaching climax. Another few seconds where he suddenly speeded up into the violent short strokes and her body convulsed as she began a long orgasm. Everything happened at once; her hips jerked uncontrollably, she gasped out unintelligible bits trying to describe what was happening to her, her fingernails raked his upper back as he was now lying on her body with his hands under he bum pulling her hips tighter into him as he bellowed out his own intense climax, shooting his cum deep into her. I was so taken up by what I was witnessing, my own wife, the woman who promised to be only mine for life and forsake all others, being fucked out of her mind by a black bull stud, I didn't even realize I was furiously wanking my own hard cock. When I felt the very first stirrings of rising cum, my senses returned and I slowed my hand so I wouldn't come just yet. I wanted to wait to come in her after Alex was finished with her and returned her to me as he left. They fucked each other for close to a full minute. The sounds they made as they both worked through their orgasms were incredibly erotic and I had great difficulty keeping myself from coming. They finally quieted, with Alex just very slowly stroking his hard cock in her pussy. She was looking adoringly up at him and pulled his head down for a kiss. The kiss turned into a full on snog and she slowly began using her legs, still wrapped around his waist to fuck him back. Their next fuck had already started. Over the next ten minutes or so, he made her come twice more in missionary, but held himself back, letting her cry out her orgasms whilst not coming himself. I could tell he was building up a big finish to their first session of the evening. After her third orgasm, he withdrew and rolled her over onto her tummy. He mounted her with his legs outside hers and slipped his cock between her bum cheeks and pushed it up her flooded pussy from the rear. He fucked her as she lay there prone on the bed. The angle must have been different or maybe his cock penetrated her deeper in that position for she was going wild under him. She was crying out that his cock felt more than wonderful, that she had never been so filled, and she going to come. He said to her at that moment, "You go, girl, give it up for me. Go on, you can do it. Come for me." His urgings soon had the desired result. She came with uncoordinated writhing of her bum and hips. She gasped and cried out gibberish as the intensity of her orgasm made her crazy. He slowed his thrusting for maybe a half minute to allow her to come down a bit, and then he speeded up and soon had her coming again. He slowed down so she would start to come down, and then he again speeded up and gave her another climax. I soon lost count how many times he did this, until she cried out one last come and groaned that she couldn't take another orgasm. He started speeding up one more time and said to her, "One more, girl. One more so I can come. You'll like it. I promise." He fucked her with the violent short strokes and within seconds bellowed out his climax as he shot another load up her. She was so fucked out, she didn't come with him, but just lay there letting him use her, although at the very end, as he gave her several really deep thrusts whilst coming in her, she did cry out with passion. He lay in her slowly stroking his cock in and out for a short while, and then he withdrew and got off the bed. She just laid there on her tummy. Giving off low moans as her breathing slowly returned to normal. By the time Alex had dressed and left our bedroom saying he would see himself out, she was sound asleep from exhaustion. I laid myself next to her on my back and wanked my rigid cock, spraying cum all over my belly. It took a minute to calm down. I wiped myself with the towel on the floor next to bed and soon fell asleep, even though it was still early. I awoke several hours later at about midnight and she was still asleep. So much for fucking her afterward. I went naked downstairs and closed up the house for the night, then returned to our bedroom. She had turned over onto her back and when I rejoined her in bed to put out the light, she apologized for falling asleep instead of fucking me. I told her 'no worries', and we went to sleep. When I awoke in the morning with a raging hard on, she was in the ensuite. She soon returned and slipped in next to me, wide awake and with a wicked smile on her face as she said, "I'm still a bit sore so I put some lubricant inside and around the opening. I'm sure you're horny to have me so. If you're gentle with me, you can have all you want as thanks for a wonderful evening." I rolled between her legs and eased up her as gently as I could. She told me it was OK and I could have her. I fucked her, but came rather quickly as the images of her with her bull stud dominated my brain. I lay in her afterward, slowly stroking with my still hard cock. In less than a minute I wanted her again, and asked if she was up to it. She just hugged me tightly and humped her hips up into me as her answer. I fucked her again, and very surprisingly, I managed to come again like a teenager. Our sex life for the next two weeks or so was once or twice each day as we remembered and relived that evening. As you can guess, Alex visited us again not long after. We now have him every four to five weeks to rejuvenate our sex life.
