It had been some time since I had started the whole thing with my ex brother-in-law, Paul and his kids, Sue and Mark. I had finally arranged to have Mark find out his dad was also fucking his sister Sue and he accepted it without a problem. I was fearful that since he was the one who took Sue's cherry he would show so much jealousy he might have blabbed the whole thing all over town. No problem....we were one big happy sexy family. Well, I was just an aunt, but still part of their close knit group.
We had made it a ritual to have our Friday night's dinner in a local steak house and we would drive over in Paul's van. One night during dinner Paul came up with a suggestion that we might want to take mini vacation down to the Maryland shore. The beaches were nice and the weather was getting prime for some ocean swimming. Sue promised to get on the Internet and find some reasonable accommodations for us. Either one room with two king-sized beds or two adjoining rooms, each with a king-size playground.
I have a younger sister Sally to whom I had let slip what was going on between Paul's family and me and she was ecstatic about wondering if there was any way she could get in with us. I promised to see what I could do. She is only twenty-two and while her tits aren't quite as large as mine they are as firm as any I had ever seen. She is as pretty as a picture and has a body most women would kill for. She had been going with a guy for a couple of years but he was killed in an auto accident a year or so earlier. That night at the restaurant I casually let it out that my sister would love to join us in any mini vacation we would take and would be more than happy to pay her share of expenses. Both Mark and Sue jumped in with comments about how it might spoil our 'other' fun. Paul looked at me as I nodded that she wouldn't spoil it but instead would join in with us. That cinched it.... Sally was in.
It was going to be a four-night vacation and by leaving on Wednesday afternoon we could be there by dinner and ready for some serious fun ...read that as sex.
Sally fit right in with them during the car ride and by the time we arrived at the shore she was totally accepted...that is with her clothes on. It hadn't gotten around to the sex part yet.
The room was perfect. Just as I hoped, it had two huge king-size beds that we were able to slide together and make into one humongous playground. The hotel was right on the beach and we could step out on our own private balcony to look at the ocean below. Just perfect.
We had hinted around at sex with our conversation in the car but never got into any serious details. I figured that I was the one who was going to break the ice ... after all, she was my sister. I said that it was still early enough for a late dip in the ocean and stripped nude laying my clothes over the back of a chair and shouted.
"C'mon guys. Don't just stand around with your fingers up your butts. Get your clothes off and your bathing suits on"
Sally was right behind me and Paul soon followed. When he got a look at her luscious body his dick sprang to attention and all she could say was,
"Holy shit. You have a flagpole for a cock."
"Well, you better salute the flag at the top of it." He joked in response.
"Oh, I'll do better than that." She said as she dropped to her knees in front of him.
Sue and Mark were just standing there watching this and I went over to them asking if there were ready to join in the activities. One look at Sally's body and Mark was chomping at the bit to join in... as long as Sally was going to be part of the fun. I could see that Sue was feeling a little left out when she saw the size of Sally's tits and then she looked over at my globes and she felt a little inadequate. I had to rectify that and do it now.
"C'mon you two...strip." As I was saying that I went behind Sue and reached around to cup her breasts in my hands. She leaned her head back at me and turned her head to plant a huge kiss on my waiting lips. This girl could turn me into a full-fledged lesbian given half the chance.
They each had their clothes off in a hurry and I reached over and took Mark's cock in one hand as I pushed Sue over to the bed with my other one. When the backs of her legs hit the edge of the mattress I gave one harder push and she was soon lying on her back and I had pulled Mark with us. Before joining Sue on the bed I leaned forward and took Mark's cock in my mouth and let one hand reach back to fondle Sue's love box. They were both ready!
Sally and Paul were busy on their half of the playground and we had the other half to ourselves. I pushed Sue up to the top of the bed and soon had my face buried in her pussy. I had gotten up on my hands and knees while doing this and pulled Mark behind me. He quickly got the right idea. His cock was harder than a board and he was positioning it in line with my pussy when I felt him give one big push and he drove it home. Damn, this kid hasn't learned the meaning of taking it slow and easy yet. I didn't appreciate him driving it into me so hard but now that it was there it felt great. He was holding my hips with each hand and was pulling me back to him as he thrust into me. Sue had each of her hands on the sides of my head and was pulling me deeper into her with each stroke of my tongue.
I looked over at Sally and Paul and he was flat on his back with her riding his cock fast and furious. She looked over at me at the same time and just nodded. She had never seen me eat pussy before but I knew that before this weekend was over she would have eaten both Sue and me.
It wasn't long before Paul was grunting his familiar pre-orgasm noise and Sue was almost right in sync with him. I could feel the warmth starting deep within me as Mark pulled out and was jerking himself off and shooting his warm come all over my back and Sue's upper body. Sue could barely feel it for she was howling like a banshee as she had her own giant orgasm. I just lay my head against her lower abdomen and looked over to see Sally being driven to her own huge blast. Paul was holding her hips and pulling her further down on his cock as he let go with the orgasm he had been working up to. Everyone was happy ... except me.
I just turned over and lay back and asked
"OK, which of you love birds are going to give me what I need?"
They all looked at each other and I figured now was the time and reached over and took Sally's hand and pulled her to me. Her eyes opened as large as dinner plates and all I said was,
