Hubby and I are in our early 40s. Our only child finished school and moved away for work last year. Right after that the house next door became vacant and Tom, a widowed retired military man in his early 60s, moved in. Hubby and Tom quickly became rather good friends. Last month I overheard Tom telling hubby how lucky he was to have such a sexy wife. I had never considered myself to be a particularly good looker being plain faced and a bit overweight, so I was flattered, and started seeing Tom in a different light. Even though retired, Tom keeps himself in great shape. One night last week the three of us went out to dinner at a local hotel. After dinner we went into the hotel bar where they were playing dance music. Hubby and I danced a few times until he had to use the loo. While he was gone, they played a slow one and Tom asked me to dance. As we danced, his hands soon were seductively rubbing my back, and it felt so good I was feeling butterflies in my tummy and heat between my legs. When they followed with a second slow one, hubby was still not back, so we continued to dance and Tom led me to a dimly lighted portion of the dance floor and lightly kissed me as we slowly swayed to the romantic music. It felt so good to be kissed by another man for the first time in over 20 years, I impulsively kissed him back. He ran his tongue over my lips and when I reciprocated, he took that as a sign to proceed and slipped his hands down to my bum. As we continued kissing, he kneaded my bum cheeks through my skirt as he pulled my hips tightly into him. I could feel his hard cock pressing against me and I was a goner. When I pushed my hips into his, he whispered in my ear, "I want to take you to bed." I was so gobsmacked that an attractive man wanted me that way I didn't say anything. I'm sure I looked flustered at his suggestion, not knowing how I felt about being unfaithful to hubby after all these years, as well as wondering if I would satisfy a lover's expectations. The music soon stopped and we went back to our table just as hubby was returning. The rest of the evening was uneventful and I gradually settled down, but the thought of his proposition still excited me and was definitely in the back of my mind. In bed that night hubby wanted a leg over and the thought of having a cock in me really turned me on imagining it could be Tom's cock inside me if I wanted. So, as hubby was kissing me and rubbing my pussy under my nightie, I was much more than usually horny remembering what happened with Tom earlier in the evening, and I became more frisky than usual. When he put his head between my legs and ate my pussy, I came more quickly and much more passionately than normal. And when he got between my legs and fucked me, I had a much deeper and more intense orgasm than usual imagining it was Tom in me. Afterward, hubby commented on how hot I was, and I just smiled. The next morning right after hubby left for work, I was still horny from the encounter with Tom on the dance floor and the sex with hubby afterward the night before, so I stayed in my short nightie covered by my dressing gown and sat on an easy chair in the lounge thinking about what it would be like to go to bed with Tom. I got so hot, I started to play with myself, caressing my breasts with one hand and rubbing my clit with the other. About two-thirds of the way to a climax, the door bell rang. It startled me since it was unusual for someone to ring that early in the morning. I jumped up from nervousness at being interrupted on my way to a come, and went to the door. When I opened it, Tom was standing there. He looked at me dressed the way I was together with the aura I must have been giving off, and he said with a knowing smile, "I'm glad I caught you dressed the way you are." I stupidly asked him why, and he said, "Isn't it obvious after last night? Have you thought about it?" When I started to stammer a reply, he continued, "Are you going to invite me in? If you keep me waiting here much longer, the neighbours might start to wonder." I stepped aside and he came in. I was still a bit startled, so he closed the door, took me by the hand and led me into the lounge where he had sat us on the sofa. He was sitting right next to me, our thighs touching and him still holding my hand. My mind was trying to catch up with my emotions when he asked if I had thought about what he had said to me on the dance floor. When I started to stammer again, he gently pulled me into him and kissed me. Without thinking, I kissed him back. He deepened the kiss. I followed and we soon were into a full on snog with tongue and sucking. I hadn't felt this horny in quite a while and knew I was lost - I was going to let him have me. My breasts tightened and I began to feel heat between my legs; and he hadn't touched me yet in either place. We continued kissing and he placed a hand on one of my breasts and the nipple instantly hardened when he rubbed it with his thumb. He felt my reaction and said, "I want you and I think you want me also." I nodded and he began kissing me again, but this time his hand moved inside my dressing gown to between my thighs. I found myself opening my legs for him. Feeling my legs open, he slipped his hand up under the hem of my nightie and I felt his fingers on the bare skin of my thigh as he slid them upward toward my heat. I squirmed on the seat cushion as he neared his objective and gasped when his fingertips gently stroked my naked slit. He suddenly said quite surprised, "You're already wet." When he ran his fingers up and down my slit, I moaned with quickly rising passion. A man other than my husband was seducing me, and I was letting him. I wanted him to fuck me as much as he did. I gasped with surprise when he slipped two fingers inside and started to finger fuck my pussy. I was hot, and getting hotter. I pulled him with me when I leaned my upper body back and opened my legs wide. I began pushing my hips upward in a humping motion, asking for more. I groaned with rapidly rising passion as his fingers sped up. His fingers were soon fucking me at breakneck speed and my moaning increased and became deeper. I finally came, moaning and gasping out my orgasm. My whole body trembled as I felt several waves roll over me. My orgasm was so intense, I fell into a sexual haze and my body quieted. I just lay there with my eyes closed, breathing rapidly. When I recovered my composure and opened my eyes, he was knelt on the floor between my legs after having pushed his trousers and pants down below his knees. He was slowly wanking his fully erect cock as he was waiting for me to come out of my haze. I reflexively recoiled from the sight of his manhood, but then stared at it as he stroked it. Seeing me wide awake, he moved his hips forward as he guided the knob end toward my pussy entrance. When it made contact and nestled at my opening, he murmured, "You look beautiful, and I want you now." Then I watched him insert the knob end into me. It instantly felt wonderful although it momentarily stretched me a bit. I was to commit adultery, and I didn't care. I just wanted, no, I needed to experience a man other than my hubby fucking me. I placed my hands on either side of his hips and pulled his cock into me. I was so wet from the climax he had just given me with his fingers he had no trouble sliding all the way up me. I then moved my hands up around the back of his neck and pulled him in for a kiss as I moaned with longing. His cock felt wonderful up inside me, and even better when he started moving it in and out. I was being fucked by another man and loving it. I kissed him with passion as he increased the speed of his thrusting until I was breathing deeply. I soon said to him without embarrassment, "God, your cock feels so good in me. Fuck me. Make me come." And he did. We fucked for several minutes as my passion increased. I was rolling my hips, urging him onward, trying to help him bring to a climax. When it hit me, I gasped and cried out that I was coming. He fucked me harder and faster, and soon came himself. I felt his hot cum explode inside me, and it prolonged my own orgasm. I was gripping his back with my hands, digging my nails into his flesh, as I came. Our bodies trembled and jerked against each other as we worked through our orgasms, and then we slowly came down, ending up hugging each other tightly. When we were finally finished, he pulled out and I felt a bit of his cum flow out of me and saw his cock covered with it. It was so erotic, I wanted more. He sat back on his haunches and just stared at my wide open pussy as I stared at his still half hard cock. He looked at me and asked, "I have you again - right now." I smiled and nodded 'yes', and started to stand. He stood with me and quickly slipped off his trousers and pants, leaving them on the floor, as I wordlessly led him down the hall to the spare room. Once inside, we kissed and I then watched him undress the rest of the way. I marvelled at his firm and muscular body, unusual for a man of his age. I had him get on the bed on his back as I slipped off my dressing gown, but retained my short nightie. I straddled his hips and lowered my pussy onto his cock, fully hard again. I spent several minutes rolling my hips and fucking him as he caressed my breasts and squeezed my nipples until I came again. He held off coming and we spent the next hour or so fucking in several different positions, ending up with him fucking me hard and deep from the rear, giving me a series of quick comes, one right after the other, which finally exhausted me. We slept for about half an hour, and when we awoke he fucked me again missionary and gave me his final bit of hot cum. We then lay there enjoying the afterglow, until prudence made it imperative he leave before anyone came to my front door. That night hubby was the beneficiary of my sexual awakening and afterward wondered aloud what had gotten into me (his exact words). I almost inadvertently gave it up, but managed to give hubby some neutral reply. Tom and I have fucked in his house every work day morning since. I can't get enough of him. Some days I return in the afternoon for a second session. I don't know where this is going, but I don't care. I just need to be fucked by him. This is probably some sort of mid-life crisis, but I'm enjoying it without thinking too much about the consequences. Luckily, I can go out my kitchen door and get to his back door without being seen by the neighbours. I'm sure our intense passion for each will eventually cool but, until it does, I'm taking advantage of having my lover right next door and as horny for it as me.
