I know exactly when I became a hotwife. It was almost 20 years ago when I turned 40 and it happened at the massive birthday party my husband gave me at our very large multi-story house. Between people we know in our two businesses, our extended families, and other friends, there were almost 200 people there that night. It was held in our extensive garden, with music for dancing in our huge lounge, and a bar set up on the center counter in our large size kitchen. My husband constantly told me I had the body of a fit 30-year old, and rightly so with all the running and weight training I did. I was proud of my slim, trim, tight body with still firm 36D breasts topped by long, stiff nipples when aroused. For several years he had been suggesting I have other men with him watching and participating, but I always put him off. But this evening, after too many drinks and the persistent attentions of my neighbor and good friend Bea's much younger guest, I suddenly was ready to take the plunge. Bea's younger man lead me to an upstairs guest bedroom where we locked the door and embraced in a passionate hug. I let him roam my mouth with his talented tongue. I love deep, wet kisses and, as is usual when kissing hubby, the feelings of arousal they engendered went straight to my groin. I felt his hands move over the thin material of my dress to my breasts where they roughly caressed and kneaded. He then concentrated on my nipples, rolling them between his fingers until they became hard and elongated. By now, I was gringing my hips into his groin with some urgency and could feel a bulge there. He could tell I was horny for sex as he unzipped my dress and pushed it over my hips, down my legs, and off. I kicked it away, then stood there completely naked, having taken off my bra, tights, and knickers in a downstairs loo before letting him lead me upstairs. He quickly shed his clothing and, as he stood up, I admired his cock which was as long and thick as my hubby's somewhat large endowment and smiled at the thought it would soon be sliding up me. My pussy was already swollen and wet with arousal, and he hadn't even touched me there yet. He deeply kissed me as he inserted a hand into my groin and slid his fingers along my slit, discovering for himself how wet and ready I was. I moaned as his fingers caressed my slit for a short while, then concentrated on my swollen clit, gently flicking it for a few moments, then rubbing it with greater force. I came with a shout, then humped his hand as I enjoyed an extended climax.. When he felt my passion start to subside, he shoved several fingers into my entrance and plundered my pussy, caressing its walls looking for my 'G-spot". When his fingers glided over it, my hips gave a lurch and I cried out, "That's it!" He concentrated his fingers there, rubbing and sliding. It took just a little while for another climax to hit me and I cried out, "Oh, my God, fuck me! I need you to fuck me now!" He pushed me onto the bed. I rolled onto my back, opened my legs, and began fingering my pussy as I was so hot at the thought of fucking a man other than my husband. He immediately climbed between my wide open legs, inserted his cock as he lowered himself over me, and pushed all the way up in a single thrust. I grunted as he seated his cock fully in me, then wrapped my arms and legs about his body and urged him to fuck me hard and deep. He immediately complied as he said, "You really don't waste time. Doesn't your husband fuck you enough?" Between moans of pleasure, I replied, "He fucks me just great, but this is your lucky night. Fuck me hard!" His thrusting got a lot faster and rougher, and we rapidly climbed the peak amidst my moans and groans of pleasure. Within a minute or so, I moaned, "I'm close! Fuck me harder!" He immediately pounded his cock into me without mercy and I soon went over the edge, my pussy convulsing in climax as I violently shoved my hips into him and I shouted, "I'm coming. I'm coming! Don't stop. Fuck me!" I held him in a death grip with my arms and legs as he pummeled me through a long and intense orgasm. When my body finally stopped convulsing, he was gentleman enough to continue stroking his cock in me as I then slowly recovered from my heights of passion. When finally finished, I lowered my legs from around his waist, pulled his head to my lips and deeply kissed him with gratitude for a fabulous fuck. We hugged and kissed for awhile, then he said with a grin, "My turn", and rolled me onto my stomach. He pulled my hips up as he knelt behind me and I pushed my legs apart as I steadied myself on my hands and knees. He inserted the head of his cock and pushed in with a single stroke until he was firmly ensconced within my swollen and wet pussy. With his hands gripping my hips, he rapidly pounded into me. It felt good - very good - so good I rammed my hips back into him in time with his forward thrusts to make sure he was penetrating me to the maximum. I was still so horny with my desire to experience another man, I wanted him to literally violate me with his cock. He sensed my need and established a rising rhythm of hard pounding that was pushing me rapidly toward another climax. I gasped as I said to him, "I gonna come soon, very soon. I'm already close. Fuck me hard and come in me. I want to feel your cum in me!" As I dropped my upper body down onto the bed, he pounded his cock into me so hard it felt like he was going to come out the other side! It felt so wonderful, I was groaning incoherently with passion. Each stroke of his cock stretched my pussy a bit and sent strong tingles throughout my body. He had my body wavering at the edge of a chasm of sensuality, then his pounding cock finally pushed me plunging over into an unbelievably intense climax. As the fabulous waves of orgasm rolled over me, I cried out, "Oh, my God! I'm coming! Don't stop! Fuck me forever! Don't you dare stop!" He pounded even harder into me as his own climax rapidly approached, sending me into even greater heights of passionate release, then he loudly grunted, "Oh, fuck!", as he came deep in me. I could feel his hot, sticky cum hitting my cervix. He gave me several spurts, grunting each time as our bodies worked through mutual orgasms. When finally finished, I collapsed onto the bed on my back and he did the same. We lay side by side regaining our composure. I had never felt so wrung out after a fuck and could hardly move. After kissing me deeply as he caressed all my good parts, he reluctantly got up from the bed saying, "We need to get dressed and go downstairs before we're missed." He rapidly got dressed, but I remained on the bed on my side leaning on my elbow facing the door as I watched him finish dressing. He looked at me quizzically and asked, "Aren't you coming?" I smiled as I replied, "I've already come twice." He retorted, "You know what I mean!" "Yeah", I grinned, "but I'm going to stay here awhile. Do me a favor. I know you came with my neighbor Bea, so please ask her to point out my hubby to you, then you tell him privately where I am and that I need to see him." He nodded his agreement, then said, "That was fabulous and I'd like us to do it again soon." I smiled as I replied, "Maybe that can be arranged." I remained there naked on the bed - no clean up or any other preparation. A few minutes later, there was a soft knock on the door as it opened part way and hubby's head appeared around the edge. He looked a bit startled when he saw me, then came in and locked the door. He approached the bed and stopped at the foot of it, staring at me with lust on his face as I rolled onto my back and raised my knees as I spread my legs for him. He saw my birthday lover's cum smeared all over my groin and a clump of it oozing out of my pussy. He grinned as I then slowly and seductively rolled my hips up at him, sliding two fingers in and out of my pussy, and said, "Do you need more of an invitation? If so, I don't what else I can do to get you to fuck me!" He shed his clothing in record time, got between my legs and shoved his rock hard cock up me with enough force to bang my head against the headboard. He fucked me hard and deep, just the way he knows I like it, finishing with a violent pounding that brought both of us to intense mutual climaxes with me shouting out mine and him bellowing out his. He deposited a tremendous amount of cum in me, so much that it immediately started leaking out onto the sheets below my bum. His cock hadn't lost its hardness when he came and he continued fucking me, knowing both of us love to feel his cock stroking into my cum filled pussy. He soon speeded up and pushed us toward another climax. We came with mutual shouts of intense pleasure, then deeply kissed each other as we came back to reality. As extremely satisfying as it was to fuck another man, having my husband fuck me was just as good - I just love the way he moves in me! When we were both finished, he said to me, "You were fucked earlier by Bea's friend, weren't you?" I nodded, then added, "You've been trying to get me to be with another man for years, so when a young, handsome guy pursued me for over an hour and caught my fancy, I let him as a birthday present to myself. Are you angry?" He looked at me with a combination of lust and love as he replied, "No, I'm not, but I wish I could have watched him fucking you and then had you myself afterward." I hugged and kissed him, and said, "We'll work all that out tomorrow, but for now, I want you to fuck my brains out the rest of the night!" "What about our guests?', he asked, and I replied, "They'll figure it out when we don't see us back downstairs." He smiled as he got between my legs again and didn't leave my body alone until morning. We fucked in all our favorite positions and I lost count of the number of times he was in me before we got up mid-morning. The sex was fabulous and when I told him that, he said the image he had of another man being in me and making me come kept him hard all night long. Laying in bed the next morning, it didn't take long for us to agree on us having threesomes and foursomes, and under certain conditions, me having one off affairs when on business travel. And we've been doing that for almost 20 years now, but more about that later. I found out from Bea the next morning that she and my birthday lover stayed until everyone else left, then locked up the house for us. She told those who asked where we were that we were celebrating privately upstairs, then winked knowingly. Bea suspected her guest and I had fucked and, when she asked him, he just took her to the door of the guest bedroom he and I had used and Bea listened to the sounds of hubby and I fucking. While she listened, her guest fingered her to a come, but we were too involved with each other to hear her cries of completion. They then went to a bedroom further down the hallway and fucked for an hour or so before going back to hers for the rest of the night. When Bea and I talked the next morning, I suggested hubby and I have a foursome with her and my birthday lover, but that's a story for next time.
