I was raised going to nudist resorts with my family. I always thought that my parents were swinging with others during those stays. At 15 I was given my own cabin, out of site of my parents place. Friends for many years at the resorts were Tom and his sister Anne. It happened when I was 17, Tom was 16 and Anne 15. We hung out a lot, and would spend some time in my cabin since I had it alone. I'd seen Anne since she was 8 or so and watched her body grow into a woman, the same for myself and for Tom. Tom was thinner than me, I was more muscular, Annes pubic hair was fuller and darker brown than Toms.
One evening I ended up fucking Tom. He was practically begging for it and I gave it to him. It was the first sex for us both. I loved having my cock inside someones warm body, and cumming deep inside someone was incredible. He kept wanting more and more, he was there in the evening after Anne would leave, he came first thing in the morning, each time wanting cock up his ass, and in order to accomodate, I made him take it in his mouth as well. Finally I told him that he had to help me get Anne high and fuck her. He didn't want to, I think out of jealousy and not wanting my cock inside someone else. But he did help. In front of him we both were hard, I could see some juices accumulating between her hairy pussy lips. She and I were kissing, I started playing with her nipples, and she was moaning incredibly wanting to squirm away but I and Tom held her in place. With encouragement from Tom, I moved down to her spread legs and ate her pussy. It was incredible, I loved the taste, the smell and at some point I let Tom take over. Anne didn't know that I had stopped, and thinking it was me she was orgasming as I kissed her and squeezed her nipple. Eyes wide open and in mid orgasm she didn't want it to stop. After than Tom got her in orgasm build up again, and he moved and I replace his mouth with my cock. Tom saw his sister lose her virginity.
After that I spent the next few weeks fucking brother and sister, betting sucked, and even fucking Anne in her butt. It hurt her a lot, so I didn't do it too much. By then Tom and I were sucking and fucking in front of her, and she and I in front of Tom. She let Tom lick her pussy but not fuck her and I got her to suck his cock a couple of times kissing her after he unloaded in her mouth. On the second to the last night I got her to agree that Tom could fuck her ass so that she couldn't possibly get pregnant from her brother. She did it for me, not for her and not for him. I promptly crawled on top of Tom and fucked him while she sat and watched with her brothers cum in her ass.
The next year, it was over with Anne. She'd gotten a steady boyfriend so it was just Tom and I. But I still jack off to the memories of taking the virginities of a brother and sister.
