I was twenty when I met Carmen. She was with a large bunch of people in a little country pub. They were clearly celebrating something. The landlord had told them several times to keep it down or he would kick them out, Well he eventually did and for some reason I got lumped in with them and also got ejected. The main bunch decided on the next pub they would go to, but there was two that didn't have transport. One of them was Carmen. Right from the start I fancied her like hell, so I offered them a lift so I could get closer to her. Three pubs later I offered her a lift home. Carmen said only if I dropped her mate Judy home first. Eventually at her parents house I got a nice kiss and when I asked for a second date she said yes. We quickly became an item, but beyond kissing and a grope of her boob she wasn't giving anything away. I wrongly assumed she was saving herself for the big day. Then one evening we were parked up and I was having a grope of her tits and a kiss. Every time my hand got anywhere near her pussy it would get shoved away. Then suddenly she pushed me away completely. "There's something I want to ask you," she said, "I know you want it. But you have to do something first," she added. Naturally I told her anything, as any young man wanting to get into a young ladies knickers would. "You have to do my sister first," she told me. Wow I thought I'd hit the jackpot, two for the price of one. I was about to say yes when she continued. "Rosie is a little older than me," she added. A bit of older pussy, I was up for that. "She's blind and rarely ever goes out, so she never meets any men, but she really wants to have sex." I was surprised, but still up for it if I was to finally get into Carmen's panties. It was nearly another month and I still hadn't have my way with Carmen when she announced that her parents would be away for the night and she had to "sister sit". This was my chance. Carmen's parents went of just after eight o'clock and by half past I was in their house. Carmen introduced me to Rosie. Other than her wonky eyes she was actually quite good looking and even had a better looking pair of tits than Carmen's. I didn't know what the plans were and must have looked silly waiting for something to happen. "Are you going to do it?" Carmen asked. I told her yes and she told me to go with Rosie to her room. Once in the room with Rosie I pulled her to me and gave her a kiss. She was totally inexperienced and probably never been kissed like that before. She seemed a little scared and was shaking. I asked her if she was ok and she told me she was a little scared and would it hurt. She wasn't my first virgin and I told her a little at first, but then it gets very nice. She asked me to be gentle with her. I slowly undressed her. I discovered under her loose fitting clothes she had a cracking body. I told her that she had a beautiful body and I lay her on her bed. and lay next to her kissing her and fondling her tits. They were nice and better than Carmen's. I kissed her neck and ears and Rosie was beginning to moan and groan. I worked my way down to her tits and spent quite a while playing with them and chewing on her large nipples, Then as I worked my way down to her navel she was trembling. I wasn't sure if it was excitement or fear. She jumped a little as I twirled my tongue in her navel. Then I was going down and over quite a bush of thick brown pubes to her pussy. Even with her legs splayed the lips still hid her treasure. I licked up and down the lips a few times and they started to peel open. I helped them along with my tongue. Then my tongue found her clitoris and she almost jumped of the bed as she yelped at the first contact. The door came open and there stood Carmen. I think she thought I had just taken her sister's virginity and looked surprised that firstly I was still fully dressed and secondly I was with my face and not my cock in her sisters pussy. I decided to ignore Carmen and resumed licking Rosie's pussy. Now she was getting used to it Rosie was positively cooing as I liked up and down her gash. She would jump just a little every time my tongue touched her clitty. Then suddenly Rosie's hands were on the back of my head before she started shaking and thrashing her arms and head around. She was in the throws of probably her first man made orgasm. As she slowly came down from it I got off the bed and got undressed. Then I was fumbling in my trousers for the condoms that I had bought for the occasion. Carmen saw what I was doing as I went to open one and informed me that I wouldn't need them as both Rosie and her were on the pill. I went back between Rosie's legs and licked her pussy a little more to get her climbing that hill again before moving up her body and taking aim with my cock. I eased it between her pussy lips and applied a little pressure. Her pussy didn't yield and she moved a little and my cock slipped up and over her clitoris. I took aim again and this time applied a little more pressure and again she moved and my cock slipped away. The third time I pushed harder than the last two times and I felt her hymen give way and the first inch or so was inside Rosie's tight pussy. Her fingernails were digging into by back. I held still while she got used a little, to having a cock in her pussy. Then as she stopped digging her nails into me I asked her if she was ok. She said it hurt, but was going off a bit. I withdrew just a little not wanting my cock to fall out and then pushed again. Now my cock was well and truly embedded in her pussy. Her nails were digging in again, so I held still again. Then as the fingernails eased off I withdrew almost all the way and thrust again. I was now balls deep and as the nails were back, I again held still. Now the nails had gone I started a slow steady pumping of her pussy. Rosie's hands had gone from my back and were now on my arse. I started kissing her again as I slowly pumped away at her pussy. Although I hadn't been with that many girls, she had by far the tightest pussy that I'd had the pleasure of. The Rosie started to hump back at my cock as I was on the downward thrusts. She broke our kiss as she started to moan extremely loudly. She was now setting the pace by humping at me at the speed she wanted and then she was pounding herself at my cock. I could feel myself getting ready to cum, but wanted to hold on as long as I could. It was no use as Rosie thrust with two really hard thrusts and then held the lat one as she came and the contractions in her pussy seemed to suck the cum from me. I collapsed on top of Rosie. As we regained control Rosie was kissing me and thanking me. As if a randy young man with raging hormones needs any thanks for fucking a girl. Then my cock slowly slipped from her pussy in it's poor limp lifeless state. Then I realized that Carmen was still stood watching me. She had witnessed me taking her sister's virginity. I climbed from between Rosie's opened thighs. The evidence of our encounter were obvious, besides my cum slowly leaking from Rosie's pussy, there was blood both on my cock and Rosie's thighs and arse and even a little on the sheets. Carmen told Rosie that we needed to get her cleaned up. I think Rosie would have been happier to lay there basking in her new womanhood, but Carmen pulled her to her feel and I followed as she steered Rosie into the shower. I stepped into the shower with her under the hot water and lathered Rosie's body. While we showered Carmen went of to change and make up Rosie's bed. Rosie wanted to touch my cock to see what it felt like. Who wouldn't like a young lady to play with their cock. I could feel it recovering and growing slightly. Rosie asked how come it could get into her if it was so soft. I explained that it got mush harder. She asked me to make it harder. I told her it wasn't quite that simple and probably the best way to get it hard again was for the girl to suck it in her mouth. To my amazement Rosie got down and started sucking it into her mouth. I had to explain what to do and not to bite it and keep her teeth off it. She was soon getting pretty good and my cock was certainly paying attention. Then Carmen returned with towels. She looked a little annoyed seeing her sister on her knees sucking my cock, especially as she could see that I was enjoying it so much. Before I could come she had the two of us out the shower and drying off. I was more than a little disappointed. Once dressed she had Rosie sit in her chair eating her breakfast. Then she had Rosie listening to her favorite radio station. Carmen told me it was now her turn. We went to her bedroom and undressed each other. Carmen was quickly on her knees sucking my cock. It was clear that she hadn't done that many if any times before and I had to tell her how to please her man. Like Rosie she took to it like a duck to water and I was soon having to stop her or I would have come again. Carmen climbed on the bed and laid on her back with her legs open. Like with Rosie I kissed and licked my way down Carmen's body I played special attention to her tits and pussy. I brought her to an orgasm as I licked her. As I played with her pussy and looked at it I could see her hymen. I was pretty sure she was also a virgin. That was confirmed when I crawled up her body and positioned myself at the gates to heaven, Carmen suddenly gasped, "Be gentle I'm a virgin." I told her I knew she was as I slowly applied pressure to her pussy for access. I felt her hymen pop and I was in. There was quite a gasp from Carmen, but no nails. I asked if she was ok and she said she was. I gave a thrust and I was almost fully home and as she hadn't complained and stopped me I withdrew and pushed gain. I was now balls deep. Carmen gasped and gave a sort of gurgle sound. I held still for several seconds. Then started long slow strokes. Like her sister her hands moved to my arse and were very soon pulling me into her pussy. Carmen came and went rigid for a few seconds as I continued to pump her pussy. then she was humping with me as we rose to the pinnacle and as she shook and moaned I dumped my load deep inside her. After we recovered, showered and dressed, Carmen changed her bed and proceeded to get the washing machine on. I felt like the luckiest person in the world having taken the virginity of not one but both sisters. It didn't happen again for several years. Their father died and I spent more time at their house than my own and then her mother was in an accident and I moved in after the funeral. I had been having regular sex with Carmen during our courtship. Now in the house permanently with the two of them the temptations were too great for both Rosie and I and we made love again. I couldn't believe how different they were in bed and what they like. Rosie liked doggy where as Carmen liked on her back with her legs on my shoulders. Rosie came many times in one session and Carmen only ever came twice if she was lucky. I must admit they became equally as good in giving blow jobs. Then Rosie went into hospital and had an operation on her eyes. Afterwards she came out with about 90% vision which was great. The inevitable happened and Carmen caught us making love. To my surprise she brushed it off saying that she guessed we were fucking. I tried on lots pf times to get them together, but the nearest I ever got to a full threesome was them kissing each other on the lips and playing with each others boobs. They wouldn't entertain touching the others fanny, But who am I to complain. Over thirty years later and two children with Carmen and one by Rosie, we still all live together. Over the years I have often floated the idea that a second cock could come in handy, but neither of them was interested.
