When I met Caroline, I fell in lust with her before I fell in love with her. She was dressed in high heels, nylons, a tight skirt which finished above the knee and a tight, low-cut knitted top. Caroline has large beasts, her tummy pleasantly rounded, but her best feature of all is her beautiful, big bum and thighs.
When I met her mother, I saw instantly where she got it all from. Dorothy was built exactly the same way, but slightly taller and with a larger tummy. Like her daughter, Dorothy's bum and thighs were magnificent, She dressed less formally, usually in loose fitting summer dresses but nearly always with tan-coloured nylons and high heeled shoes.
Caroline was still living with her parents when I met her, but they were relaxed about me spending time there including staying overnight in Caroline's room. What became apparent was that they were relaxed about plenty of other things too.
My relationship with Caroline developed quickly and passionately as we explored each others' preferences. Her large build and elegant dress sense were a huge turn-on for me, and I delighted in taking off her outer clothes and exploring her large body through ample bras, deep suspender belts which covered her round tummy, and best of all, nylon stockings which came very high up her big white thighs.
What I learned quickly about Caroline was that she was unable to achieve orgasm with a man's penis inside her, instead preferring stimulation to her nipples and clitoris. I would do this as a prelude to intercourse, either with my fingers or with my tongue. Also, she liked to finger herself to a cumshot while I watched, sometimes urging her on with the use of language and sexual swear words which she loved. Often while masturbating, she liked me to tell her sexual stories about previous lovers, taking particular delight when I related tales of my sexual relationship with a former landlady and her husband, both 44 years my senior.
Our sex was lust-filled, erotic and often frantic. The best part for me was that foreplay was like acting out a fantasy while making her cum her spunk. Each of her orgasms lasted for ages, during which she was loud and vocal, either crying out loudly or shouting dirty words like "fuck me, I'm coming, fuck me, fuck me, you dirty cunt, I'm doing it now, right now in your mouth..."
After this, she was so well lubricated that I always slipped easily inside her and fucked my cock up her dirty hole until I unloaded my own filth inside her big belly. During my cumshot, she would sometimes use the same sort of foul language to me to heighten the intensity of my cum. On some occasions, when she chose to masturbate herself in front of me, I would take my cock in my hand and wank it up and down while watching her. Very often I couldn't hold on and the sight of her big tits wobbling, her nipples being rubbed and tweaked, her big bum and fat thighs, and her middle finger wanking away side-to-side on her clit was all I could bear, and as she brought herself to climax I would shoot my filthy blobs over her vagina, her wanking hand, her stocking tops and her fat thighs.
Despite having all the erotic sex I could manage, I remember being transfixed by her mother's bum, tits and legs. She was more than 50 years old, and as she was a big lady, when she sat in her armchair in the drawing room, she would have her legs wide apart, forced open by her ample thighs as larger ladies sometimes do. This gave the casual observer a magnificent view of her stocking tops, a glimpse of thigh and sometimes even the gusset of her knickers. She was perfectly aware of this, and jokingly told me I was a pervert and that I shouldn't be looking up there. This was said jovially, often while Caroline and other family members were in the room, much to everyone's hilarity. What they didn't know is that in stealing a glimpse of Dorothy's forbidden up-skirt, I was fuelling a fantasy which I thought about during masturbation.
In this relaxed atmosphere, I mockingly called Dorothy 'mum' as Caroline did, and over time it stuck to the extent that I hardly ever used her Christian name, choosing instead to call her mum as if she were my own mother.
Over the coming months, a few things happened which only added to the heady sexual atmosphere when Dorothy was around. Firstly, I went to the family bathroom one afternoon for a pee, but as I opened the door, I saw Dorothy lying down in the bath rinsing her hair in the water. Her eyes were closed and her ears were under the water line and she had no idea I was there. I froze for a few seconds before backing out through the door, but in the time I was looking I had a very vivid picture. Dorothy's legs were bent at the knee, and wide apart, and as she lay back her pelvis was thrust upwards to the top of the water. I got an uninterrupted view of her hairy cunt stretched wide open and the pink inner lips swollen in between, much like Caroline's are after masturbation. Dorothy's huge tits were flattened by her posture, and were flopped down to the sides of her big chest and looked to be floating on the surface of the water. My abiding memory was her enormous, flabby thighs parted with her knees bent as she lay there massaging her hair.
I closed the door behind me and said nothing to anyone about it, but secretly my wank-fantasy had been fuelled again, and while I fucked Caroline later that night I pretended it was Dorothy spread out under me. It was too much to bear, and I started to cum up to my cumshot immediately. As I did so, I looked Caroline in the eye, and pretending I was speaking to Dorothy, said "I'm spunking up you, you dirty fat cunt". I had never had a cum which had lasted such a long time or produced so much filthy sperm. As I fucked my cock in and out of Caroline's cunt slit I could feel the cumshot running out of her fuck-hole and down over my balls and her bum hole onto the bed.
After we finished, Caroline commented that I was getting more and more adventurous in bed, and that I shouldn't stop as she enjoyed it as much I did.
Another thing that happened was one night after a party for a friend of ours in the local pub, Caroline and her dad decided to walk home at about midnight. I told them I wanted to stay and talk to some friends, and unbeknown to me Dorothy had stayed behind as well and was talking to the couple who lived next door to them. Their names were Brian and Leslie, and she was quite tall, well built and 'statuesque'. Brian was shorter, balding but well built and very outgoing. Over the months I'd come to know them quite well, as they socialised with Dorothy and Jim, Caroline's father, on a regular basis.
Eventually, I set off on the 10 minute walk to Dorothy and Jim's house to join my beloved Caroline in bed. As I approached the house, I could see two people in the driveway at the side of the house near the back door. They were hidden from the road, but as I walked up the drive I could see that it was Dorothy with Brian from next door, and they were locked in a passionate embrace. She was leaning against the side wall of the house, he was leaning against her kissing her fully on the open mouth, and at the same time, his hand was up her dress rubbing her through her knickers. Her large legs were open as wide as they'd go to allow him access, and he was rubbing his groin against her fat thigh.
I froze, eyes wide open, not knowing whether to proceed, withdraw, cough to announce my presence or just stand and watch. After only a few seconds, Dorothy noticed me, stopped kissing, pushed Brian's hand out from under her dress, and simply said "Hello, you're back soon."
