My husbands parents were both dead before we met and he lived with his older sister Jean and her husband Alf in Aberdeen. As we were getting married there and, as my husband to be was in the forces, it was arranged that I would stay with his sister for the three weeks required to establish residence. My husband would then come up for the wedding. Almost from the first day Alf came on strong to me and I must say I was flattered. At the time I had just turned nineteen and I confess three months pregnant and here was this tall handsome dark haired man in his thirties making a fuss of me. To my surprise Jean didn't seem bothered that he was flirting with me, in fact she seemed to encourage him. For a few days nothing much happened except that Alf took every opportunity to rub against me when we passed or to pat my bottom. For my part i didn't make any overt moves but when we were sitting around and I could see him looking at my legs I did open them slightly to give him a view of my stocking tops and suspenders. Then one evening Jean said that she was going to a Womans' Institute meeting and wouldn't be back until about ten o'clock. I later discovered that she was really going to meet a boy friend who was regularly fucking her. As soon as she had gone Alf immediately sat beside me on the sofa and kissed me pushing his tongue between my lips. I returned his kisses opening my mouth so that our tongues inter-twined. As he kissed me he moved a hand on to my breasts and squeezed and caressed them through my dress. I could feel my nipples hardening under his touch and he unbuttoned the dress and pulled it open exposing my white bra which he quickly pushed up freeing my tits. Even after three months pregnancy my tits were quite full with my hard red nipples standing out He bent and began to suck my nipples which got even harder and I could feel my cunt begin to moisten. Still sucking my tits he moved a hand down on to my knee and slid it slowly up my nylon stocking pulling my dress up as he went. I shivered as his hand ran over my stocking top on to my bare thigh and then right up between my legs feeling my cunt through my knickers. He laughed and said, "Your knickers are really wet." I said, "You have made them like that." He then made me stand up and took my dress and bra off so that I was standing in front of him in just my stockings, suspenders and white nylon knickers. He pulled down my knickers and bent forward to examine and then kiss my cunt. We then went into my bedroom and he got completely undressed. He had the biggest cock that I had ever seen standing out hard and throbbing. We got on the bed and he went down between my wide spread legs and started to suck and lick my cunt and clit which was now sticking out hard and red. I was panting and moaning and close to cumming and I gasped, "Oh Alf fuck me now. Fuck me now." He moved up the bed and pushed his big knob against my cunt lips. It was by far the biggest that I had ever felt and the lips were stretched wide open as his cock slowly forced its way into me. Once inside I felt completely filled and he began to thrust in and out gradually speeding up. I could feel his knob pressing against my cervix and in no time I was panting and moaning with my legs wrapped round his waist. After one particularly hard thrust I was screaming, "Oh.Oh. I'm cumming. I'm cumming." and my voice tailed off as I just seemed to be having one continuous cum. He went on ramming hard into me until with a shout his cum spurted into me. We lay for a while kissing and caressing and I sucked his cock and balls until to my delight his cock got hard and he fucked me again making me cum twice more. That was the first time Alf fucked me but by no means the last and over the years he must have fucked me dozens of times.
