Many years ago when we were in our late 20s I urged the wife to try some black cock as her first extramarital experience. When she finally agreed, I arranged for a married black work mate to take her whilst I watched. She didn't want him in ours so we picked him up one Saturday when his wife was out shopping with her friends. He sat in the rear seat with my wife as we drove the 20 minutes to a secluded rural spot I had previously scouted. They made out, but very tentatively at first because she was skittish about doing it and about me watching. I observed in the mirror as I drove and witnessed the progression of her arousal. He was very patient and gentle with her as he took her through the stages of seduction. He first got her comfortable kissing a black man, then touched up her breasts, unbuttoned her blouse and then unclipped her bra to cup and suck her breasts, and then suck and tweak her nipples to hardness. When he got her nipples hard like little pebbles she was sufficiently aroused and used to him handling her privare parts so it went faster. She willingly opened her legs when his hand slid from her knees up between her thighs to her panties. By the time he got there she was into it and spread her thighs wide as possible and moved her bum to the front edge of the seat. He proceeded to rub and finger her cunt through her panties as they deep kissed, and I heard her first moans. She very willingly raised her bum when he used two hands to pull her panties down her legs and off. He dropped them in my lap as I drove and then went back to kissing her as he explored her cunt without the panties in the way. I sniffedher panties and smelled her pussy juice in the gusset. As I did she was moaning as he rummaged her slit with his fingers, and then I heard her gasp once, and then again a few seconds later (she later told me that was when he pushed first one and then a second thick finger up her pussy). Soon she was moaning fairly steadily and I could see in the mirror his hand thrusting up between her thighs and I knew he was finger fucking her. That's when I made the final turn and stopped between some trees of the country lane. I saw no one was about so I knelt in my seat facing the rear set and leant over so I could watch him doing her. I opened my trousers, pulled my half hard cock out and then brought my handkerchief out of my pocket. I was ready for when my passion would overtake me from watching my wife with another man and I would need to wipe up. He was still finger fucking her as I finished my preparations. Her moans were coming closer and closer together, marking her progress toward an orgasm. The scene before me was erotic in the extreme. My wife with her blouse and front opening bra wide open slouched facing front with her thighs spread wide open, and he half sat nest to her and leant over kissing her mouth as his hand furiously fucked her pussy with the two middle ones buried inside. I was stroking my cock and getting hotter by the second as I heard her moans mounting and her hip straining upward. And then she came, her mouth breaking contact with his as she wailed out her come. Her hips were thrusting upward against his hand that was still furiously fingering her pussy. Her head was rolled back, mouth open uttering cries of passion, and her eyes shut tight. Her orgasm and its intense aftermath lasted well over a full minute. Then her body visibly sagged and all movement of her part ceased except for some residual tummy tremors. When she finished he withdrew his hand and smelled his fingers, obviously enjoying the odour of her pussy.. Then he half turned toward me and thrust that hand under my nose and said, "You want to smell your wife's pussy?' I sniffed it deeply. He noticed my handkerchief in my hand and said to me, "Don't do that. You'll want to fuck her bad after I'm finished, so save it for her. You'll thank me later." He turned back to her and kisses her as he asked if she had enjoyed that. She gave him a long drawn out 'yesss', and he asked if she was ready for his cock. She glanced my way looking embarrassed and hesitated. He looked at her and told her not to be embarrassed as I was obviously enjoying watching her with him and expected to see her take his cock into her pussy. The crude words made her wince but gave her the picture of what we were there for. He then added, "And you're so hot I can't wait to fuck you." That must have been the right thing to say for she reached up and pulled him into a long and deep kiss, at the end of which she whispered something to him I couldn't hear, so he said, "Say that again so he can hear you. Yeah, he'll want to hear you say it. Look at your husband and tell him what you want me to do." When she hesitated, he continued, "Don't be afraid, tell me what you want me to do to you but loud so he can hear. What do you want me to do?" She whispered it and he told her to say it out loud. She then said to him whilst watching me, "I want you to fuck me." My cock was rock hard and it actually twitched hard when she said it, and I resumed wanking it. He pushed down his trousers and pants, and then knelt between her thighs. I leant over the seat further towards my door so I could see her cunt as he pushed his hips toward it. He quickly wanked his cock to a full erection. She reached out to enclose it in her hand. He removed his hand and she caressed it, moving her hand up and down it, then wanked it for a few seconds. As she did that, he looked around at me and said, "You sure you still want me to fuck your wife. Say out loud so she can hear you tell me to fuck her." I did what he asked and told him to fuck my wife as she and I stared into each other's eyes. He then took his cock back from my wife's hand and placed the knob end nestled right up against her pussy hole, but held it there as he said to her, "You need to tell me to push it in and fuck you." No hesitation on her part as she said in a determined voice, "Yes, put it in and fuck me." He pushed the knob end just inside and she moaned, "Oh, God, yesss, fuck me!" He gripped her shoulders and thrust in about half way, quickly withdrew about half of that as she gave out a loud gasp, and then pushed it in the rest of the way. My wife gave out a second gasp, even louder than the first; but I had the feeling it was more from surprise at such a determined penetration than from any real discomfort. I was proven right when she almost immediately strained her hips upward in a bucking movement. He had paused fully up her at her second gasp, but noticed her attempt to fuck him, so he began thrusting his cock into her. He gave her 10 or 15 steady thrusts, but then began playing with her pussy. He withdrew his cock all the way and with his hand guiding his cock he would push in a couple of inches and then immediately withdraw if fully; and then in a few inches again and then out all the way. He did this severl times and she moaned with frustration for she obviously wanted him to fuck her steadily. He was giving her fulfilling sensations with the forward thrust of his cock and then a feeling of emptiness when he jerked it back out. It was driving her crazy. She had her hands on either side of his waist trying to get him fully into her and then trying to prevent his withdrawal. This ent on for a minute or so, at the end of which he was asking her when he pulled it if she wanted him to put it back in. She was moaning, "Yes, yess! Fuck me with it. God, just fuck me!" She was desperate for it. My normally calm and somewhat reserved wife was going out of her mind and begging another man to fuck her. It was so hot I wanted to wank to a come, but held off with great difficulty. Finally, after maybe another minute of this teasing, he pushed in all the way up her and held it there letting her feel his whole length fill her. She brought her knees up on either side of his waist and squeezed them. At the same time she put her hands on his upper back and dug her fingernails into his skin there, indicating she wanted him to fuck her to completion. He asked her rhetorically 'do you want me to fuck you now'. She didn't respond, just moaned as she fucked him with her hips. That's when he began steadily thrusting his cock into her like she wanted. On his withdrawals I noticed her pussy discharge begin coating his cock. As he continued fucking her that coating increased. Her pussy was enjoying the feel of fullness from his cock and was secreting more and more lubrication as a sign her body was getting ready to climax. By now she was moaning steadily and he increased speed. She followed his lead and was straining her hips upward harder and harder as her moans turned into gasps. Her breathing was becoming more and more strained. His fucking was becoming quite intense and I noticed his bum cheeks begin to clench with the effort. Both of them were on the edge and then both began loud climaxes. There was mutual body jerking, and moans and gasps and cries of completion. Their bodies were a jumble of strong reactions to their overpowering orgasms and they writhed against each other as they came. My cock was rock hard as I watched and I needed relief badly. As she began her come down, my wife was moaning with heavy breathing, things like, "Oh, God. Oh, God. I can't believe how good - how good. Don't get out! Stay in me." He kept his cock inside, slowly stroking her pussy; but I could see it slowly deflating. He kept in as long as he could, but then pulled his body back and when he sat on his heels I could see her whole cunt framed by her wide open thighs. His cock had left her pussy entrance wide open, and it and the surrounding hair was covered with his thick cum, with some slowly dribbling out and down her arse crack. She just laid slouched back against the seat looking fucked out. He turned to me and said it would be a while before he could fuck her again, and I should have her now. We switched places and I laid her down lengthwise along the rear seat. She was half out of it and said to me she wanted him again. I told her he would later. I placed one of her feet up on the top of the seat back and her other foot on the floor. That opened her up as wide as the seat would allow. I got naked from the waist down and knelt between her legs with one knee on the seat and my other foot on the floor. This allowed me some leverage and II mounted her with my rock hard cock. The sensation of pushing my cock in her pussy and thrusting it in his cum was unbelievable. It made me instantly even more randy and I almost couldn't control my thrusting. I fucked her quickly to a come, remained hard afterward 'soaking' my cock in her swamp of a pussy, and then I fucked her a second time, again to a come. She had finally finished recovering from her orgasm with him during my second fuck and fucked me back, but I was too far gone and came before she could do likewise. After I finished, she asked me if she could have him again. We switched places and he mounted her again. He fucked her twice more in quick succession and she came once. After they cuddled and kissed a while, it was all over. I drove us back with them still in the rear seat kissing and fondling each other, and just before we dropped him off he gave her a final come with his fingers up her pussy. He became her regular 'fuck buddy' and would visit on the nights his wife was at her club meetings which was once or twice a month. To say my wife getting anpther man's cock on the side enhanced our sex life between times would be an understatement. She was randy for a few days afterward and again for some days before the next visit. I was the beneficiary during those days with one and frequently two sex sessions per day. And on the other days we had sex at least every other day. So if you husbands reading this want an almost constantly randy wife, get her one or two 'friends with benefits', but make sure you're part of it.
