This is a true story about my ex-wife.Her name is June,she is 45, has short natural auburn hair,medium build with small breasts and puffy nipples, good legs and a tight shaven pussy.We used to have a good sexual relationship, she liked different positions, especially on top either facing me or turned away from me moving gently up and down on the palms of her hands whilst I supported her waist. She also enjoyed a good 69, but preferred the tip of my tongue against her clitoris rather than me licking around her lips and deep into her cunt. However, after several years of marriage we drifted apart and the good sex became more irregular and almost automatic. We had lost our deep feelings for each other. One night we were at a friends party at his house in the country. It was midsummer and a beautiful evening. Unfortunately June was in a foul mood as usual and we left each other to have a good drink and chat with the other guests. Several scotches later I realised I hadn't seen her for some time and had a quick look round but couldnt find her. Bugger this I thought, let's have a look round the garden. It was a large garden and quite dark in places, I heard a rustling sound by a large tree and paused , taking cover behind a dense shrub.I didn't want to disturb anyone having a bit of fun. I could make out two figures as my eyes adjusted to the light.They were kissing,their tongues flicking together before their mouths sucked greedily with a great desire. The woman moaned , it was my wife. I felt despair, but I also felt strangely excited. I had been expecting this . Itwas a bitter sweet moment as I felt my cock press angrily against my trousers. June unzipped her tight fitting dress from the back and slipped it from her shoulders. The man, who I did not know but recognised from the party, bent his head and nuzzled gently at her see through bra; the night was so clear I could see her beautiful nipples stiffening. June groaned and ran a hand through his hair. He cupped a breast in one hand and slid off the other bra strap and took a breast from the cup with his other.He was getting excited now and bit eagerly at her breast and then ran his tongue around the base of June's nipple. "I want to fuck you" he said firmly but quietly. June nodded. I undid my zip and roughly grabbed at my cock. This was it. I felt sick, i felt exhilarated. June took off her dress and half slip. She stood there in her stockings, suspender belt and briefs.I remember they were matching black when she dressed this evening. That seemed so long ago now. She leant against the tree, she seemed to be shivering with lust and intent. The man had taken his trousers off , she put her hand against the bulge in his pants. He groaned and told June how beautiful she looked. June took her thumb and finger and rubbed them gently up and down against his still covered erection. They kissed and held each other. I began masturbating slowly. June took off his pants and his cock sprang free. She gasped at it's thickness and told the man that she'd waited for this for a long time. She bent down and ran her tongue around his taut helmet it looked fit to burst. She stood up and slowly slid her briefs off. THey both seemed in a dream. She turned her back to him and he moved gently against her , kissing her hair and stroking her breasts. She thrust against him and gasped as his thick cock slid slowly into her pussy. June grunted and her arse and cunt moved backwards and forwards in response to his measured thrusts. It couldn't last long , their feelings were too strong and I came just as his back arched and he ejaculated into her waiting pussy. They seemed shaken as they kissed and dressed; they made their arrangements for a furher session the following week. This time we'll have time to do it properly they said. I felt hollow, bit I wanted to see more. The rest of the story will follow later.
