When I was in my early fifties I found my self single but moderately successful with my own business as such I was playing the field a fair bit. Encouraged by my sister and adult children I met a lovely Lithuanian girl through the internet whom I’ll call K. Over thirty years younger than me with very striking looks Tall and slim she was a real boost to my ego. After chatting on line for a few months I took a short break to her country. The attraction was instant and the sex brilliant. To cut a long story short within a year we were married and she moved to the UK. A year later we had a little boy whom I love dearly. Over the next few years we had a very active sex life. K. is a very confident and likes to dress to impress , as such she gets a lot of attention when we go out and she flirts a lot. With the old adage “ You pump up the tyres and I’ll ride the bike” it did not bother me, indeed it was a bit of a turn on. Unfortunately I’m now in my late sixties as such my libido has waned a bit . The mind is willing but I do need our friends Viagra and Vibrator to satisfy her. Conversely K. is now 37 and in her prime. She still has her stunning looks and great body which she likes to show off and dress very sexy. Just before Covid we took a break to Puerto Banus where I have friends and we holiday most years. My sister offered to look after our son and the plan was to try and revive our sex life. To a degree this worked. We would go out in the evening Kat looking both sexy and glamourous. Some time she would get hit on by guys more her age . We would go to clubs and I was happy for her to dance with other men . My ego stroked when they clearly wanted to get into her knickers. This turned us both on and we would go back to our villa to make love. Our neighbour was an expat Russian Guy also name beginning K. but I’ll call him X for clarity. He was single mid 40’s .Tall with a good physique. We often met for drinks on previous visits and knew K. had a soft spot for him . She is multi lingual and speaks good Russian so naturally got on well. On this visit we me ta couple of times for drinks and K. would flirt with him outrageously. For our final night X. invited us out for a meal which was kind of him. K. took extra care in getting ready and chose a simple slip dress teamed with killer heels. She also laid out her favourite matching underwear but I dared her to leave them off. Hence my young wife came out with nothing under her clingy short dress. It was obvious she was not wearing a bra. A fact much appreciated by X. We had a great night and got absolutely shit faced, K. invited us back to his for a night cap. It was a relatively warm evening so we sat outside on one of those King size loungers. K. sandwiched between X and my self. As I said K. is flirty and tactile , having lost any inhibitions she cuddled up to X. and before long I noticed his hand move down from her shoulders to her breast. She did not object. The next thing they were kissing ! We have often fantasized about a three some and K. making out with other men and some how it seemed the most natural thing for me to join in and massage her vacant boob. Pushing things a little further I pulled her straps down to reveal her naked breasts. This signalled it OK for him to start sucking her nipple. I then went in for a fufingers joining minell French kiss. K. was really turned on I could tell. K. reached out to undo his shorts and released a dick that I could see was far bigger than mine. Soon he was fully erect and K. was wanking him. Meanwhile I moved down to give her fully shaved fanny some attention . She was soaking !! As I slid two then three fingers in her hot hole X had started kissing her again and was teasing her boobs. I was determined to give her an orgasm. It didn’t take long ! Before she could go off the boil I was aware of his fingers joining mine. In tandem we frigged her to a further shattering orgasm . As she subsided I moved back up to give her a loving kiss, I was grateful for fulfilling a fantasy. X however was not finished and continued his admistrations. K. then unbuckled my shorts and proceeded to give me head. She is fabulous at this. It was only then I realised that X had moved down was inching his huge cock into my darling wife.. She stopped sucking to catch her breathe only to say “ Oh Fuck”. Followed my several “Fucks” I was too far gone to object as X continued to fuck her with long slow strokes. “ Fuck Me harder” she said between gobbling me. It was too much for me as I spurted down her lovely throat. Mean while X continued his thrusting as K. literally squirmed on his fat cock that probably touched parts only reached by her biggest dildo’s. One would thought it would be embarrassing after but no , it seemed so natural. We all lay sweating for a while before I offered to go and recharge our glasses. I took my time and before long they were at it again. Through the kitchen window I could see K. sucking his impressive cock back to full strength. Out of love I stayed put and watched her sit cowgirl style on his huge rod. They fucked for probably another 15 minutes before I returned As if to claim her I could see he had given her love bites on her neck and on her breasts. K. looked thoroughly knackered or rather shagged out. It seemed only natural again to take up his offer to go to bed. I slept till dawn when I was woken by the movement of further fucking. K, was facing me as he made love to her spoons style. She put her fingers to my lips and whispered “ Thank you “. Back home I was conscious that I may have unleashed the beast and have tried my best to keep her satisfied. Trouble is she is pestering me to go away again and I know we will end up in X’s bed. I have too much to lose , do I relax and enjoy the ride or do I risk her wanting more ?
